Cambridge Audio SX80 Floorstanding Speaker - Single (Certified Refurbished)

The Cambridge Audio SX80 is a 3-way bass-reflex floorstanding speaker that pairs twin 165 mm (6.5″) treated paper cone woofers with a 25 mm silk dome tweeter to deliver effortless full-range performance, room-filling scale and the natural tonality that defines Cambridge Audio’s signature clarity.

Twin 6.5″ long-throw woofers — Two 165 mm treated paper cone woofers deliver rich, full-bodied bass and a strong midrange presence, capturing the weight and scale of demanding music with controlled low-end output.

25 mm silk dome tweeter — A dedicated 25 mm (1″) silk dome tweeter handles the high frequencies with smooth, refined treble for clear, detailed reproduction across vocals, strings and cymbals.

2-way D’Appolito driver array — Twin 6.5″ woofers flank the centrally-mounted silk dome tweeter in a D’Appolito configuration, with a precisely tuned crossover at 1.6 kHz for a coherent, focused stereo image and accurate phase response.

Rear-firing bass-reflex port — A rear-mounted bass-reflex port extends low-end response and overall efficiency, delivering deep bass without compromising clarity (allow roughly 30 cm of clearance from the rear wall for optimal performance).

Rigid MDF cabinet — Hi-fi speaker engineering starts with the cabinet, and the SX80’s rigid, well-braced MDF construction is developed using computer-aided modelling to minimise unwanted resonance and coloration for clean, distortion-free playback.

Precision-crafted crossovers — Optimised crossovers are engineered for seamless integration between drivers, ensuring phase accuracy and a natural, immersive stereo image with real depth and dimensionality.

Wide frequency response — Covers 40 Hz–20 kHz to render deep bass, refined treble and everything in between with accuracy for both two-channel listening and home-theater playback.

Recommended amplifier 10–100 W — With 87 dB sensitivity and an 8-ohm nominal impedance, the SX-80 is rated for amplifiers from 10 to 100 W per channel — making it an easy pairing with everything from compact integrated amplifiers to mid-power AV receivers and dedicated stereo amps.

High-quality binding posts — Secure binding posts accept thick speaker cable or banana plugs for a reliable, fuss-free setup that adapts to whatever cabling you already use.

Vibration-isolating floor spikes — Included floor spikes mechanically isolate the cabinet from the floor to reduce external vibration and ensure stable, precise performance regardless of the surface beneath.

Stereo and home-cinema ready — Equally at home as the front pair of a two-channel hi-fi system or as front L/R speakers in a surround setup, the SX80 slots cleanly into both stereo listening rooms and full home theaters.

Modern, stylish aesthetic — A contemporary, elegantly simple design lets the sound take centre stage, fitting naturally into modern living rooms and AV setups without dominating the décor.

Floorstanding hi-fi proportions — Each speaker measures 240 × 980 × 338 mm and weighs 16.9 kg, giving the SX80 the cabinet volume and stability needed to anchor a serious system without overwhelming a typical room.

The Cambridge Audio SX80 floorstanding speaker is the natural choice for listeners who want big, confident sound from a polished, contemporary tower. With its twin 6.5″ woofers, silk dome tweeter and bass-reflex MDF enclosure, this pair of hi-fi speakers pairs seamlessly with a Cambridge Audio integrated amplifier or a stereo network receiver to build a complete two-channel system — and slots equally well as the front loudspeakers in a 5.1 home cinema setup, where its scale and dynamic ease genuinely show their worth.
