Dynaudio Emit 25C Centre Speaker

Audio T Verdict

The Dynaudio Emit 25C is the dedicated centre-channel speaker for the Emit range, combining the same Cerotar tweeter and 14cm MSP driver technology used by the matching stereo models.

Its 2.5-way layout uses two MSP drivers positioned on either side of the tweeter, giving dialogue convincing body while providing the dynamic ability required for films, television and multichannel music.

The Cerotar tweeter includes Dynaudio’s Hexis inner dome to control resonance, while the MSP drivers use one-piece cones, copper-clad aluminium voice coils and dual-stacked ferrite magnet systems.

With 87dB sensitivity, a 4-ohm impedance and 180W IEC power handling, it deserves a capable AV receiver or power amplifier. Better amplification brings greater clarity, control and composure during busy soundtrack sequences.

Its rear bass-reflex port and 550mm-wide cabinet require sensible installation planning. The speaker should be supported securely, centred in relation to the screen and given enough rear clearance for the port and cable connections.

For an Emit-based home cinema system, the Emit 25C is the natural choice. It provides the tonal consistency needed to keep dialogue and effects coherent as they move across the front soundstage.

Dynaudio Emit 25C Centre Speaker

The Dynaudio Emit 25C is a passive 2.5-way centre-channel loudspeaker designed for home cinema and multichannel music systems.

It combines:

  • One 28mm Cerotar coated fabric soft-dome tweeter
  • Dynaudio’s Hexis resonance-control inner dome
  • Two 14cm MSP drivers
  • A model-specific 2.5-way passive crossover
  • A dual-flared rear bass-reflex port
  • A rigid and internally damped cabinet
  • A removable black magnetic grille
  • A single pair of loudspeaker terminals

The Emit 25C is supplied as one centre speaker rather than as a stereo pair.

The Centre of an Emit Home Cinema System

The centre channel commonly reproduces the majority of dialogue, centrally positioned voices and many of the effects anchored to the picture.

Its responsibilities can include:

  • Film and television dialogue
  • Narration
  • Front-stage music
  • Effects positioned in the centre of the screen
  • Sounds moving between the left and right front speakers
  • Vocals within multichannel music recordings

A correctly matched centre speaker helps voices remain attached to the screen and prevents their tonal character from changing as effects move across the front soundstage.

Designed to Match the Emit Range

The Emit 25C uses the same Cerotar tweeter and related MSP driver technology as the rest of the current Emit family.

It can be combined with:

Using speakers from the same range helps maintain a consistent tonal balance through the front channels and around the complete surround system.

Closely Related to the Emit 30

The Emit 25C is closely related to the Emit 30 floorstander.

Both models use:

  • One Cerotar tweeter
  • Two 14cm MSP drivers
  • A 2.5-way crossover arrangement
  • Related crossover frequencies
  • Shared Emit-series voicing

The centre speaker uses a horizontally arranged cabinet and different port tuning to suit its role beneath or above a screen.

Symmetrical Driver Layout

The Cerotar tweeter is positioned centrally between the two 14cm MSP drivers.

This layout provides:

  • A visually balanced centre-channel design
  • Substantial cone area for dialogue and soundtrack effects
  • A clear acoustic reference point beneath or above the screen
  • Greater output capability than a single-driver centre speaker
  • Close integration with Emit front speakers

The speaker should be centred horizontally in relation to the screen wherever the installation allows.

2.5-Way Crossover Configuration

The Emit 25C uses a 2.5-way crossover with transition frequencies at approximately 1000Hz and 3500Hz.

Within this arrangement:

  • Both 14cm drivers contribute through the lower frequencies
  • One driver is progressively filtered through the lower transition region
  • The remaining driver continues through the midrange
  • The Cerotar tweeter takes over through the upper crossover region

This provides greater low-frequency output and dynamic headroom while limiting interference between two horizontally separated drivers through the upper midrange.

28mm Cerotar Soft-Dome Tweeter

High frequencies are reproduced by Dynaudio’s 28mm Cerotar coated fabric soft-dome tweeter.

The Cerotar was developed for the Evoke range and is inspired by technology used in the Esotar Forty and professional Esotar Pro tweeters.

Its principal elements include:

  • A coated fabric soft-dome diaphragm
  • Dynaudio’s Hexis inner dome
  • A lightweight aluminium voice coil
  • A carefully controlled magnet system
  • Optimised internal airflow
  • A damped space behind the diaphragm

The tweeter is designed to provide clear dialogue, detailed effects and smooth high-frequency reproduction without excessive hardness.

Coated Fabric Diaphragm

The Cerotar uses a coated fabric diaphragm rather than a rigid metal dome.

The combination of fabric and surface treatment is selected to provide:

  • Low moving mass
  • Controlled internal damping
  • Smooth diaphragm behaviour
  • Consistent production
  • Reduced reliance on strong resonant peaks

The diaphragm, coating, voice coil, magnet and internal airflow system operate as one complete high-frequency assembly.

Hexis Resonance-Control Inner Dome

The Hexis is a small dimpled inner dome positioned directly behind the Cerotar diaphragm.

Its shape guides airflow behind the playing surface and helps reduce internal standing waves that could otherwise reflect towards the main soft dome.

Reducing this unwanted energy can improve:

  • Dialogue clarity
  • High-frequency smoothness
  • Transient control
  • Low-level detail
  • Decay and ambience
  • Integration with the MSP drivers

The Hexis concept is also used in Dynaudio’s more expensive Evoke, Contour i and Confidence loudspeakers.

Lightweight Aluminium Tweeter Voice Coil

The Cerotar tweeter uses a lightweight aluminium voice coil.

Reducing the moving mass helps the dome respond quickly to changes within dialogue, music and high-frequency effects.

The motor system must also maintain control during loud or sustained soundtrack sequences.

Twin 14cm MSP Drivers

Two 14cm Dynaudio MSP drivers reproduce the bass and midrange.

The drivers are closely related to those used in the Emit 10 and Emit 30 and incorporate:

  • One-piece MSP cones
  • Integrated central dust-cap areas
  • Dynaudio balance ribs
  • Copper-clad aluminium voice coils
  • Two-layer glass-fibre formers
  • Dual-stacked ferrite magnet systems
  • Long-throw suspension
  • Substantial rubber surrounds

The two drivers provide greater total cone area than a conventional single-driver centre speaker.

One-Piece MSP Cones

Each cone is made from Dynaudio’s Magnesium Silicate Polymer, normally abbreviated to MSP.

The cone and central dust-cap area are moulded as one continuous diaphragm rather than assembled from separate components.

This construction provides:

  • Consistent behaviour across the diaphragm
  • Controlled stiffness
  • Useful internal damping
  • A strong connection to the voice-coil assembly
  • No separate dust-cap joint to introduce another resonance

Dynaudio Balance Ribs

The small ribs visible around the central area of each MSP cone connect the diaphragm to the voice-coil assembly behind it.

These balance ribs help the cone and coil move as one controlled mechanical system.

The design distributes the motor’s force across the diaphragm and helps maintain the cone’s intended shape as excursion increases.

Copper-Clad Aluminium Voice Coils

The Emit 25C drivers use copper-clad aluminium voice-coil wire.

This combines a lightweight aluminium core with a thin outer layer of copper.

The construction provides:

  • Lower moving mass than a solid copper winding
  • Improved conductivity compared with bare aluminium
  • Space for additional windings
  • Strong interaction with the magnet system
  • Controlled transient response

The relatively light moving system is especially useful because the drivers must reproduce both bass and the critical vocal range.

Two-Layer Glass-Fibre Formers

Each voice-coil winding is supported by a two-layer glass-fibre former.

The former must remain stable as the cone moves and as the voice coil changes temperature during prolonged playback.

Glass fibre provides a useful combination of rigidity, low weight and electrical behaviour.

Dual-Stacked Ferrite Magnet Systems

Each MSP driver uses a dual-stacked ferrite magnet system.

The arrangement helps concentrate magnetic energy around the voice coil, providing the force required to control the cone during dialogue, music and soundtrack effects.

The motor system supports:

  • Improved driver control
  • Useful low-frequency output
  • Clear midrange reproduction
  • Dynamic headroom
  • Consistent movement at higher playback levels

Long-Throw Driver Suspension

The two MSP drivers use suspension systems designed to permit useful controlled excursion.

Additional movement helps the relatively compact cabinet reproduce convincing bass and lower-midrange weight.

The suspension must also keep each voice coil centred and return the cone accurately to its resting position.

Model-Specific Passive Crossover

The Emit 25C uses a crossover developed specifically for its driver arrangement, cabinet volume and centre-channel application.

Dynaudio specifies:

  • A 2.5-way configuration
  • An approximately 1000Hz lower transition
  • A 3500Hz upper crossover frequency
  • A first-order electrical topology for the tweeter
  • A second-order electrical topology for the woofer section

The crossover manages frequency division, relative output, phase and integration between the three drive units.

1000Hz Lower Transition

Both MSP drivers contribute through the lower frequencies, but one is progressively filtered through the region around 1000Hz.

This allows the remaining driver to continue through the midrange before handing over to the Cerotar tweeter.

The arrangement combines additional cone area in the bass with more controlled behaviour through the vocal range.

3500Hz Tweeter Crossover

The Cerotar tweeter takes over through the upper crossover region at approximately 3500Hz.

The crossover must preserve dialogue clarity and tonal consistency as the active radiating area changes from the MSP driver to the tweeter.

The final acoustic result depends on the natural driver responses, cabinet and baffle as well as the electrical filter components.

Dual-Flared Rear Bass Port

The Emit 25C uses a rear-mounted bass-reflex port that is flared at both its internal and external openings.

The dual-flared profile allows air to accelerate and decelerate more gradually as it moves through the port.

This helps reduce:

  • Air turbulence
  • Port compression
  • Audible chuffing
  • Mechanical noise on deep effects
  • Changes in behaviour at higher output levels

Rear-Port Installation

The rear port requires sufficient clearance to operate freely.

Placing the Emit 25C too close to a rear wall or enclosing it tightly inside furniture can:

  • Increase bass reinforcement
  • Reduce bass definition
  • Restrict airflow through the port
  • Create additional cabinet or shelf resonances
  • Make dialogue sound less clear

An open-backed shelf, dedicated centre-speaker support or well-ventilated AV unit is preferable to a tightly enclosed cabinet.

Allow Additional Space Behind the Cabinet

The official 285mm complete depth includes the grille but does not provide the additional space required for speaker cable, connectors and rear-port airflow.

Check the usable shelf depth before installation rather than relying only on the published cabinet measurement.

53Hz to 25kHz Frequency Response

Dynaudio specifies a frequency response from 53Hz to 25kHz within a +/-3dB tolerance.

At the wider -6dB tolerance, the response extends from 46Hz to 35kHz.

The difference between these figures demonstrates why frequency-response specifications should always be read with their stated measurement tolerance.

Actual in-room response will also depend on:

  • Distance from the rear wall
  • The supporting shelf or furniture
  • Room dimensions
  • AV processor crossover settings
  • Listening position
  • Subwoofer integration
  • Room-correction settings

87dB Sensitivity

The Emit 25C has a specified sensitivity of 87dB at 2.83V measured at one metre.

This is a moderate sensitivity figure rather than an especially efficient design.

The amplifier requirement will depend on:

  • Room size
  • Listening distance
  • Preferred playback level
  • Dynamic peaks within the soundtrack
  • The chosen bass-management crossover
  • Amplifier current delivery
  • The number of channels operating simultaneously

4-Ohm Rated Impedance

Dynaudio specifies a rated impedance of 4 ohms.

The partnering AV receiver or power amplifier should be suitable for a 4-ohm speaker and capable of delivering sufficient current at the required listening level.

An AV receiver’s headline power rating may be measured with only one or two channels operating. The output available when several channels are driven simultaneously can be lower.

180W IEC Long-Term Power Handling

Dynaudio specifies IEC long-term power handling of 180W.

This does not mean that a 180W amplifier is compulsory, nor does it guarantee that the speaker cannot be damaged by an amplifier carrying the same rating.

A lower-powered amplifier driven into clipping can produce harmful distortion, while a more powerful amplifier used within sensible limits may provide cleaner dynamic headroom.

Reduce the Volume if the Sound Becomes Distorted

Audible hardness, compression, crackling or obvious distortion can indicate that the amplifier or centre speaker is being overloaded.

Reduce the volume immediately rather than continuing at the same level.

AV Receiver and Amplifier Matching

The Emit 25C can be used with a capable AV receiver or a separate AV processor and power amplifier.

Important considerations include:

  • Stable operation into 4 ohms
  • Power available with several channels operating
  • Current delivery
  • Power-supply capacity
  • External power-amplifier outputs
  • Room size and listening distance
  • Required film and music playback levels

A well-specified AV receiver may be entirely suitable for a smaller Emit system. Larger rooms, higher playback levels or Emit 50 front speakers may justify additional power amplification.

Browse home cinema amplifiers and AV receivers at Audio T to explore suitable options.

Bass Management and Crossover Settings

The Emit 25C’s published 53Hz lower cutoff does not automatically mean it should be configured as a full-range or Large speaker within the AV receiver.

Using an appropriate bass-management crossover can:

  • Reduce low-frequency demand on the centre speaker
  • Reduce the power required from the centre amplifier channel
  • Improve dialogue clarity
  • Increase dynamic headroom
  • Transfer the deepest bass to a suitably positioned subwoofer
  • Improve consistency across the seating area

The best setting will depend on the room, listening level, subwoofer system and position of the centre speaker.

Check the Automatic Calibration Result

Automated room calibration provides a useful starting point, but its speaker size, distance, level and crossover settings should be reviewed.

The measured crossover should also be checked by listening to familiar dialogue and effects.

Subwoofer Integration

A suitable subwoofer handles the deepest low-frequency effects and can reduce the workload placed on the Emit 25C and AV receiver.

Correct integration requires attention to:

  • Crossover frequency
  • Subwoofer level
  • Phase
  • Delay or distance settings
  • Room position
  • Interaction with the front speakers

The centre channel should retain body and authority without sounding boomy or disconnected from the subwoofer.

Adding the Dynaudio Sub 3

The Dynaudio Sub 3 is a compact active subwoofer suitable for Emit music and home cinema systems.

The final subwoofer choice should consider the room size, required listening level and number of seats rather than brand matching alone.

Positioning Beneath the Screen

The Emit 25C should be positioned directly beneath or above the screen on its vertical centre line.

Placing it close to the screen helps dialogue appear connected to the picture rather than coming from a separate point elsewhere in the room.

Where a television is mounted relatively high on the wall, positioning the centre speaker beneath it is normally the most practical arrangement.

Aiming the Speaker Towards the Listener

If the Emit 25C must sit significantly below or above seated ear height, it may benefit from being angled towards the primary listening area.

Correctly aiming the speaker can help:

  • Improve dialogue intelligibility
  • Anchor voices more closely to the picture
  • Preserve high-frequency detail
  • Improve integration with the front speakers
  • Reduce the impression that sound is coming from the furniture

Any angled support must remain stable and must not allow the speaker to slide forwards.

Keep the Front Baffle Clear

Where practical, position the front baffle close to the front edge of the supporting shelf.

Recessing the speaker deeply into furniture can create reflections from nearby shelf surfaces and side panels.

Do not place ornaments, equipment or decorative objects directly in front of the tweeter or MSP drivers.

Strong and Stable Support

The Emit 25C weighs approximately 11kg.

The shelf, cabinet or stand must support it safely without:

  • Sagging
  • Rocking
  • Flexing
  • Resonating audibly
  • Obstructing the rear port

Large unsupported furniture panels can vibrate in sympathy with the speaker and reduce dialogue clarity.

Check the Installation Before Positioning the Speaker

The cabinet is 550mm wide and approximately 11kg.

Confirm the support’s load rating, usable width, depth, ventilation and cable clearance before placing the speaker beneath a television or projection screen.

Acoustically Transparent Projection Screens

In a dedicated cinema room, the Emit 25C may be positioned behind an acoustically transparent projection screen.

This can place dialogue closer to the visual centre of the picture, but sufficient space must be provided between the speaker, screen and rear wall.

The screen material and installation should be selected to avoid excessive high-frequency loss or unwanted reflections.

Channel-Level Matching

The centre-channel level should be matched with the front left and right speakers.

If the centre is set too low, dialogue can become difficult to follow. If it is set too high, voices may sound detached from the surrounding soundtrack.

Small adjustments may be useful after automatic calibration, but large corrections can indicate a positioning, amplification or speaker-matching problem.

Speaker Distance and Delay

The Emit 25C may be closer to the listening position than the front left and right speakers.

The AV receiver uses distance or delay settings to align the arrival time from each channel.

Incorrect settings can weaken dialogue focus and reduce the precision of effects moving across the front soundstage.

Using Dialogue Enhancement

Many AV receivers include a dialogue-enhancement or centre-lift function.

These controls can be useful for quiet evening viewing or difficult recordings, but they should not replace correct positioning and calibration.

Before applying a large amount of dialogue enhancement, check:

  • Speaker angle
  • Centre-channel level
  • Crossover setting
  • Distance and delay
  • Furniture reflections
  • Whether the speaker is obstructed

Single-Wire Loudspeaker Connection

The Emit 25C uses one pair of rear loudspeaker terminals.

The Emit series supports properly prepared stripped speaker cable and compatible 4mm banana plugs.

Cable spades are not supported by the Emit-series terminal design.

The AV receiver or amplifier should be switched off before the speaker cable is connected or removed.

Correct Cable Polarity

Connect the positive amplifier terminal to the positive speaker terminal and the negative amplifier terminal to the negative speaker terminal.

Incorrect polarity can affect dialogue focus, bass integration and consistency with the front left and right speakers.

Loose bare-wire strands must not be allowed to touch the opposite terminal.

Speaker-Cable Guidance

Dynaudio recommends speaker cable with a conductor cross-sectional area of at least 1.5mm².

Performance may begin to suffer when cable runs extend beyond approximately 15 metres, depending on the cable construction and amplifier.

Selection should consider:

  • Total cable length
  • Conductor area
  • AV amplifier compatibility
  • Connector quality
  • Installation route
  • The overall system budget

Browse speaker cables available from Audio T to compare suitable options.

Black, White and Walnut Finishes

Audio T currently lists the Emit 25C in:

  • Black
  • White
  • Walnut

All three versions use custom laminate finishes designed to coordinate with the other speakers in the Emit range.

Availability can vary according to current UK stock and production.

Black Magnetic Grille

A black magnetic grille is supplied with each finish.

The magnetic attachment avoids visible locating holes when the grille is removed and allows it to be fitted without tools.

The grille protects the Cerotar dome and MSP cones from dust and accidental contact.

Dynaudio advises that removing the grille may provide a marginal performance improvement during critical listening.

18mm MDF Cabinet Construction

The current Emit range uses 18mm MDF cabinet construction to provide a rigid and stable platform for the drive units.

The centre-speaker enclosure must resist vibration from two 14cm drivers while remaining compact enough for installation beneath a screen.

Cabinet rigidity helps reduce:

  • Panel vibration
  • Unwanted midrange colouration
  • Loss of dialogue detail
  • Mechanical noise
  • Energy being stored within the enclosure

Model-Specific Internal Damping

The cabinet uses acoustic damping material selected for its volume and port tuning.

The damping helps absorb unwanted energy behind the MSP drivers and reduces sound reflecting back through the cones.

The quantity must be controlled carefully because too much damping can also affect efficiency and bass behaviour.
