Audio T Verdict
The Acoustic Energy AE107² is a compact but capable centre speaker designed to make dialogue clearer, more focused and more natural within a Home Cinema system.
Its twin 130mm paper-cone drivers provide useful weight and dynamic impact, while the centrally positioned soft-dome tweeter and Wide Dispersion Technology help maintain clear speech across a broader seating area.
It is a particularly natural match for Acoustic Energy's current 100 Series speakers, but it can also work within other systems where its size, tonal balance and amplifier requirements are suitable.
Acoustic Energy AE107² Centre Speaker
The Acoustic Energy AE107² is a passive two-way loudspeaker designed specifically for centre-channel use in Home Cinema and multichannel music systems.
It combines two 130mm paper-cone drivers with a centrally mounted 25mm fabric-dome tweeter, a rear slot-shaped reflex port and a carefully braced High Density Fibreboard cabinet.
Its horizontal cabinet can be positioned centrally beneath or above a television or projection screen, helping anchor dialogue and on-screen effects to the picture.
The speaker requires connection to the centre-channel output of a suitable AV receiver or surround amplifier.
Sold Individually
The price shown is for one Acoustic Energy AE107² centre speaker.
It is intended for the centre channel of a Home Cinema system rather than stereo use as a pair.
Why a Dedicated Centre Speaker Matters
In most film and television soundtracks, the centre channel carries the majority of dialogue as well as many effects linked to the action on screen.
A dedicated centre speaker places this information directly beneath or above the picture, rather than creating it as a phantom image between the left and right speakers.
This can improve speech clarity and keep voices anchored to the screen for listeners seated away from the exact centre of the room.
Using a centre speaker from the same range as the main speakers also helps maintain a consistent tonal balance as sounds move across the front soundstage.
Twin 130mm Paper-Cone Drivers
The AE107² uses two 130mm paper-cone drivers positioned on either side of the tweeter.
Their long-throw motor systems are designed to provide useful output and control from the relatively compact cabinet.
Paper combines low moving mass with natural damping, allowing the drivers to reproduce voices, instruments and effects smoothly across the midrange.
Using two drivers also increases the available radiating area, helping the centre speaker achieve a specified peak output of 115dB for demanding film soundtracks.
25mm Soft-Dome Tweeter
High frequencies are reproduced by a 25mm fabric-dome tweeter positioned centrally between the two paper-cone drivers.
The soft dome is designed to provide clear detail without giving dialogue, music and effects an unnecessarily aggressive edge.
Acoustic Energy developed the tweeter and mid/bass drivers together so that they integrate smoothly through the 2.2kHz crossover region.
Wide Dispersion Technology
The tweeter sits within Acoustic Energy's Wide Dispersion Technology waveguide.
This shaped surround helps control the spread of high-frequency sound and improves integration with the neighbouring paper-cone drivers.
Broad and controlled dispersion is particularly useful for a centre speaker because several people may be watching from different positions across a sofa or seating area.
Correct placement is still important, but the waveguide helps retain intelligibility beyond one narrow central listening position.

Designed to Deliver
- Clear and focused dialogue
- Consistent sound across a wider seating area
- Useful bass weight from a compact cabinet
- Strong dynamic output for films
- Good tonal matching with the AE 100 Series
Rear Slot-Shaped Reflex Port
A wide slot-shaped reflex port is positioned on the rear of the cabinet.
The port uses air movement within the enclosure to reinforce the lower-frequency output of the paper-cone drivers.
Its broad opening and shaped internal vent are designed to smooth airflow and reduce the turbulence or chuffing that can affect smaller conventional ports.
The rear-facing design means that some space should be left between the speaker and the back of a cabinet or wall.
High Density Fibreboard Cabinet
The enclosure is manufactured using 15mm High Density Fibreboard with carefully positioned internal bracing.
HDF provides useful mass and stiffness while allowing relatively thin cabinet walls, creating more internal volume without making the speaker unnecessarily large.
The bracing helps reduce unwanted panel vibration so that dialogue and effects are reproduced with greater clarity.
Rounded cabinet edges, flush-mounted drivers and a slim magnetic grille give the AE107² a clean and understated appearance.
Positioning Beneath a Television
The AE107² should normally be placed centrally beneath the television, with its front edge close to or slightly forward of the supporting shelf.
Pulling the speaker forward helps prevent the shelf or cabinet from obstructing its output or creating strong early reflections.
Angle the speaker towards seated ear height where practical, particularly when it sits significantly below the screen.
Ensure that the supporting shelf is rigid, level and capable of safely carrying the speaker's 4.6kg weight.
Positioning Above a Screen
The centre speaker may also be positioned above a television or projection screen where there is no suitable space beneath it.
It should remain centred horizontally and angled downwards towards the main seating area.
The supporting shelf or bracket must be securely attached and should prevent the cabinet from moving or vibrating during louder passages.
Allow Space Behind the Rear Port
Avoid pushing the speaker tightly against the rear of a cabinet or enclosing it within a very small sealed compartment.
Leaving approximately 15cm where practical gives the rear port useful breathing space and can help prevent heavy or uneven bass.
Using the AE107² Inside Furniture
The compact cabinet can be placed on a suitable shelf or within open-fronted AV furniture.
The opening should be large enough to avoid closely surrounding the sides and top of the speaker, and the front baffle should remain close to the front edge.
Enclosing the speaker too tightly may alter its tonal balance and reduce dialogue clarity.
Lightweight shelving or cabinet panels may also vibrate, so a rigid supporting surface is recommended.
AV Receiver Setup
After connecting the AE107², the AV receiver should be configured so that the centre channel is active and its distance, level and crossover settings are appropriate for the room.
Automatic room calibration provides a useful starting point, but the final dialogue level should still be checked using familiar films and television programmes.
Where a subwoofer is used, the centre speaker will usually be configured as a small speaker so that the lowest bass is redirected to the subwoofer.
The best crossover frequency depends on the room, speaker position and capabilities of the rest of the system.
Amplifier Matching
The AE107² has a sensitivity of 89dB and a nominal impedance of 6O.
These figures make it suitable for a broad range of good-quality AV receivers and multichannel power amplifiers.
Acoustic Energy specifies power handling of 175W, although clean and controlled amplification is more important than choosing solely by headline wattage.
Reduce the volume if dialogue or effects become hard, strained or obviously distorted.
Single-Wire Speaker Connections
The rear terminals accept a single speaker-cable connection from the centre-channel output of the AV receiver or power amplifier.
Maintain correct polarity by connecting the positive amplifier terminal to the positive speaker terminal and negative to negative.
Switch the amplifier off before connecting or changing cables and ensure that no loose wire strands can create a short circuit.
Matching Acoustic Energy Speakers
The AE107² is designed to complement the current Acoustic Energy 100 Series.
It can be partnered with
AE100² standmount speakers
,
AE109² floorstanding speakers
or
AE120² floorstanding speakers
for the front left and right channels.
The
AE105 on-wall speaker
is a practical option for discreet side or rear surround channels.
Adding a Subwoofer
The AE107² reaches a specified 55Hz, but a dedicated active subwoofer is still recommended for the lowest film effects.
The
Acoustic Energy AE Sub
can reproduce deeper bass while allowing the AV receiver to reduce the low-frequency demands placed on the centre and surround speakers.
Subwoofer level, crossover, phase and position should be configured as part of the complete system rather than adjusted in isolation.
Black or Walnut Finish
The Acoustic Energy AE107² is available in Black or Walnut vinyl veneer.
Both versions include a slim, magnetically attached cloth grille that can be removed carefully when the exposed driver arrangement is preferred.
The finish should be cleaned using a soft, dry cloth without abrasive products, solvents or furniture polish.
