Audio T Verdict
The Spendor Classic 3/1 are beautifully proportioned standmount speakers that combine the warmth and charm of the Classic range with excellent transparency and dynamic expression.
The proprietary 18cm EP77 polymer driver provides convincing bass weight and a clear, natural midrange, while the 22mm polyamide-dome tweeter delivers smooth and well-integrated high frequencies.
Their 88dB sensitivity and 8-ohm nominal impedance make them relatively accommodating, allowing the Classic 3/1 to work successfully with capable valve or solid-state amplification.
A single reflex port extends the in-room response down to 40Hz, giving the speakers a surprisingly substantial presentation without requiring the cabinet size of the larger Classic 2/3.
Used on their dedicated stands, the Classic 3/1 offer an engaging balance of tonal richness, fine detail and room-friendly flexibility.
Spendor Classic 3/1 Standmount Speakers
The Spendor Classic 3/1 are passive two-way standmount speakers designed for smaller and medium-sized listening rooms.
Each cabinet contains an 18cm EP77 polymer bass and midrange driver, a 22mm polyamide-dome tweeter and a single reflex port.
They are supplied as a stereo pair in Cherry or Walnut real-wood veneer and are designed and manufactured in the UK.
Stands and Amplification Are Required
The Classic 3/1 are passive loudspeakers and require a suitable external amplifier.
Spendor recommends its dedicated Classic 3/1 stands for the intended listening height and mechanical support. The stands are supplied separately.
18cm EP77 Polymer Driver
The Classic 3/1 are built around Spendor's proprietary 18cm EP77 polymer bass and midrange driver.
The driver combines a cast magnesium-alloy chassis with a high-efficiency motor system, optimised electro-dynamic damping and effective heat dissipation.
Its carefully controlled cone behaviour helps voices and instruments retain their natural tonal character while providing impressive bass weight from the compact cabinet.
22mm Polyamide-Dome Tweeter
A 22mm polyamide-dome tweeter handles frequencies above the 3.7kHz crossover point.
Its compact diaphragm provides an extended high-frequency response while integrating smoothly with the larger EP77 driver.
The result is an open and detailed presentation that avoids pushing treble unnaturally forward.
Refined Crossover and Cabinet
The meticulously developed crossover network is designed to create a cohesive transition between the bass and midrange driver and tweeter.
An enhanced cabinet structure and elastomer panel damping help control enclosure vibration that could otherwise colour voices, soften transients or obscure low-level detail.
Removable magnetic grilles maintain a clean front baffle without visible mounting points when removed.
Single-Port Reflex Loading
The reflex-loaded enclosure helps the Classic 3/1 achieve a typical in-room response extending down to 40Hz.
This gives bass instruments convincing body and weight without making the speakers unnecessarily large or difficult to position.
Spendor specifically describes the Classic 3/1 as suitable for smaller rooms and relatively close-wall placement, although the final position should always be adjusted by listening.
Start with Modest Toe-In
Begin with both speakers positioned symmetrically and angled only slightly towards the listening area.
Small adjustments to wall distance, spacing and toe-in can then be used to refine bass balance, soundstage depth and vocal focus.
Dedicated Classic 3/1 Stands
Spendor's dedicated Classic 3/1 stands measure 575mm high before their adjustable spikes are fitted.
The rigid open-frame design uses precision-machined solid-alloy components with stainless-steel top supports and non-slip polymer cabinet interfaces.
Each stand weighs 9kg and is designed to provide a stable, low-mass and non-resonant foundation for the speaker.
Amplifier Matching
Spendor recommends amplification between 25W and 150W per channel.
The 88dB sensitivity, 8-ohm nominal impedance and 5.9-ohm minimum make the Classic 3/1 compatible with a broad range of well-designed amplifiers.
They can work successfully with valve or solid-state electronics, although amplifier quality and clean power delivery remain more important than wattage alone.
Single-Wire or Bi-Wire Connection
Two pairs of gold-plated binding posts provide conventional single-wire or bi-wire connection.
For normal single-wire operation, the supplied terminal links must remain fitted securely.
Check the Terminal Links
Remove the links only when using a correctly configured bi-wire or compatible passive bi-amplifier arrangement.
Incorrect connection could result in missing frequencies or damage to connected equipment.
Classic 4/5 or Classic 3/1?
Choose the Classic 4/5 When
- The smallest Classic model is required
- The room is particularly compact
- A sealed cabinet is preferred
- Close-wall positioning is essential
- 55Hz bass extension is sufficient
Choose the Classic 3/1 When
- Greater bass weight and scale are required
- An 18cm driver suits the listening room
- Higher 88dB sensitivity is useful
- A larger soundstage is important
- Dedicated 575mm stands can be accommodated
The Spendor Classic 4/5 provide the most compact route into the Classic range through a sealed cabinet.
Classic 3/1 or Classic 2/3?
Choose the Classic 3/1 When
- The room is small or medium sized
- More flexible placement is important
- A smaller and lighter cabinet is preferred
- An 18cm EP77 driver provides sufficient scale
- 40Hz bass extension suits the system
Choose the Classic 2/3 When
- The room can accommodate a larger speaker
- Deeper bass and greater output are required
- A larger 22cm driver is preferred
- Greater room-filling weight is important
- Substantial 425mm stands can be used
The Spendor Classic 2/3 step up to a larger 22cm driver and deeper 35Hz in-room response.
