Our take on the Cambridge Audio Minx X500

A sub for bass lovers

High-powered rock concerts, soulful jazz tunes, rumbling action flicks — the Minx X500 can handle all of it, and more. It delivers true home theater thunder thanks to a 500-watt built in amplifier. And it's carefully engineered to deliver audiophile-quality bass, so you can experience the visceral impact of big bass drums and baritone saxophones as if the instruments are being played right in front of you. Such room-filling performance might conjure images of a large, unwieldy subwoofer. But like all Minx speakers, the X500 was designed for a more a compact footprint than most other subs in its class.

Engineered with passion

The Minx X500 uses a 10" forward firing driver made of a single piece of super-strong, aerospace-grade aluminum for amazing punch and attack. It's paired with a bottom-firing passive radiator that adds some serious mid-bass boost. Cambridge Audio's software engineers specially designed the sophisticated Digital Signal Processor (DSP) in this sub, allowing it to pump out sensational bass from a compact enclosure. You may even be fooled into thinking the X500 is several times its size.

Cambridge Fan from Clarksville TN on 4/21/2014

Crutchfield Customer Review (What's this?)

It's hard to say how this sub measures up to others but I'm very happy with what it delivers. The bass sounds very accurate and deep. My system sounded great with one but I'm a bit of a BassHead so adding a second was in the plan. I now have two and I plan to let the neighbors know not to be afraid to let me know when it's bothering them. The first X500 came with the Cambridge 5.1 system which is awesome. The speakers are engineered well, compact, powerful, clear, clean and accurate. I'm sold.

Pros: Deep, accurate, and clean bass

Cons: Price may seem a little on the high side. However, if your a fan of good bass your money is well spent.

Product Research



Digital Signal Processor (DSP): The Cambridge Audio X500 powered subwoofer features built-in Digital Signal Processing (DSP) which allows for smaller cabinet construction without sacrificing bass response.

500W Amplifier: The Cambridge Audio X500 powered subwoofer is equipped with a 500 watt (RMS) digital amplifier for increased efficiency and reliability.

10" Woofer: The Cambridge Audio X500 powered subwoofer uses a one-piece, aerospace-grade aluminum, front-firing 10" cone woofer to move air with incredible efficiency.

Auxiliary Bass Radiator (ABR): The Cambridge Audio X500 powered subwoofer utilizes a down-firing 10" auxiliary bass radiator (ABR) for greater bass response and better efficiency. The ABR design replaces the need for bass ports to eliminate air noise at higher volume levels.

High-Gloss Finish: The Cambridge Audio X500 powered subwoofer is available in a high-gloss black (with black cloth grille) or high-gloss white finish (with silver cloth grille). The black and white high-gloss lacquers are finished to the highest standard using paint application techniques developed by premium automotive manufactures. The black and white lacquer finishes are hard to scratch and easy to clean.


Volume Control: The Cambridge Audio X500 powered subwoofer has a rear-panel rotary volume control to adjust the volume of the subwoofer relative to the other speakers in the system.

Crossover Frequency: The Cambridge Audio X500 powered subwoofer offers a continuously variable low-pass filter, adjustable from 50-200 Hz.

Phase Adjustment: The subwoofer's phase adjustment allows you to adjust the subwoofer's phase between 0° to 180°. If the bass sounds muddy or unclear, adjusting the phase control can sometimes strengthen the bass performance.

Auto On/Off: The X500's Auto On/Off feature will switch the powered subwoofer On and Off automatically by signal detection.


RCA Input: The powered subwoofer has gold plated left & right RCA line-level inputs for use with receivers having a subwoofer or stereo preamp output that do not contain their own low-pass crossover. The left channel RCA input doubles as the LFE input, if your receiver has an LFE output and a built-in low-pass crossover.

RCA Output: The powered subwoofer's gold-plated left & right RCA line-level outputs allow you to connect (daisy-chain) a second powered subwoofer.
