Cambridge SX80 Floorstanding Speakers

The Cambridge Audio SX80 are 2-way bass reflex floorstanding speakers from Cambridge Audio (London, England), available at Vinyl Sound, an authorized Cambridge Audio dealer in Buffalo, NY. With dual 165mm (6.5") treated paper cone woofers, a 25mm (1") silk dome tweeter, and a CAD-modeled MDF cabinet, the SX80 delivers an effortless, full-range soundstage that captures the scale and weight of demanding music while maintaining the speed and finesse of a smaller speaker. The SX80 achieves 87dB sensitivity and a frequency response of 40Hz to 20kHz.

Rock Solid Foundations

Hi-fi speaker engineering starts with the cabinet. Computer-aided design (CAD) was used extensively to refine the SX80's internal structures to ensure that while the drivers are vibrating with your music, the cabinet isn't. This means that every millimeter of movement from the drivers is directed where it should be — at you.

Sound Reproduction

Each SX80 speaker has two 165mm (6.5") woofers made from treated paper. Hi-fi manufacturers have used paper for years, as its impressive strength-to-weight ratio is matched by excellent tonality — so instruments sound rich, well defined, and real. The 25mm (1") soft dome tweeter, made from treated silk, handles the higher frequencies with the same balance of realism and refinement.

Many Drivers, One Voice

Cambridge Audio's engineering team took great care when designing the crossovers in the SX80, as they are responsible for ensuring that each driver receives the correct frequency. Accuracy of timing and stereo imaging depend on phase remaining completely linear, from top to bottom. The result is music that sounds engaging, energetic, and real.

Engineered, Front to Back

A rear bass reflex port helps you fine-tune lower frequencies by adjusting the position of the speakers relative to the rear wall. Immediately below, conveniently close to the floor, are a pair of high-quality binding posts that accept thick speaker cable with or without banana plugs.

Designed for Real Life

The SX80's clean, understated design exudes confidence without demanding attention. Leave the grilles on to protect the drivers, or remove them to display the SX80's driver array. Floor spikes are included to isolate the speakers from surface-borne vibration for cleaner bass reproduction.

Frequently Asked Questions

What are the Cambridge Audio SX80 speakers?

The Cambridge Audio SX80 are 2-way bass reflex floorstanding speakers from Cambridge Audio of London, England, designed to deliver an effortless, full-range soundstage in medium to large rooms. Each speaker features dual 165mm (6.5") treated paper cone woofers, a 25mm (1") silk dome tweeter, a CAD-modeled MDF cabinet with rear bass reflex port, and a phase-linear crossover, achieving 87dB sensitivity and 40Hz to 20kHz frequency response. Floor spikes are included. The SX80 is available at Vinyl Sound, an authorized Cambridge Audio dealer in Buffalo, NY.

How do the Cambridge Audio SX80 compare to the SX50?

The SX80 is a 3-driver floorstanding speaker while the SX50 is a compact 2-driver bookshelf model. The SX80's dual 165mm (6.5") woofers provide greater bass extension (40Hz vs 50Hz) and significantly greater output capability for larger rooms. The SX50 suits bookshelves and smaller spaces; the SX80 suits medium to large living rooms. Both share the same silk dome tweeter design, treated paper cone woofer philosophy, and phase-linear crossover engineering. Vinyl Sound in Buffalo, NY stocks both models for direct comparison.

What amplifier works best with the Cambridge Audio SX80?

The Cambridge Audio SX80 is rated at 87dB sensitivity with an 8-ohm nominal impedance, making it compatible with a wide range of integrated amplifiers, AV receivers, and stereo amplifiers. Its manageable impedance and sensitivity allow satisfying results from modest amplifiers, while the SX80 scales well with more powerful designs for larger rooms. Vinyl Sound in Buffalo, NY can recommend an amplifier matched to the SX80 for your listening room.

Are the Cambridge Audio SX80 suitable for a large room?

Yes. The SX80's floorstanding format with dual 165mm woofers makes it well suited for medium to large living rooms where a bookshelf speaker would fall short in bass output and dynamic scale. The rear bass reflex port allows fine-tuning of low-frequency output by adjusting speaker placement relative to the rear wall. Floor spikes are included to improve bass definition and isolate the speakers from surface-borne vibration. Vinyl Sound in Buffalo, NY carries the SX80 in Matte Black finish.

What is the frequency response of the Cambridge Audio SX80?

The Cambridge Audio SX80 has a frequency response of 40Hz to 20kHz, achieved through dual 165mm (6.5") treated paper cone woofers handling the low and mid frequencies and a 25mm (1") silk dome tweeter covering the upper range. The rear bass reflex port further extends and reinforces low-frequency output by proximity tuning to the rear wall. At 87dB sensitivity and 8-ohm impedance, the SX80 is compatible with a wide range of amplifiers. The SX80 is available for audition at Vinyl Sound in Buffalo, NY.

What are the main features of Cambridge Audio SX Series speakers?

The Cambridge Audio SX Series is a line of 2-way bass reflex speakers featuring treated paper cone woofers, silk dome tweeters, CAD-modeled MDF cabinets, and phase-linear crossovers for neutral, accurate stereo reproduction. The series includes the bookshelf SX50 and SX60 and the floorstanding SX80, each scaling in driver size and output capability while sharing the same design philosophy. All SX Series models are available at Vinyl Sound, an authorized Cambridge Audio dealer in Buffalo, NY.
