Ophidian was founded by Gareth James in 2011 with the goal of creating loudspeakers of outstanding performance.

By ignoring common conventions and thinking outside the box each part of the design process has been reimagined.

Every loudspeaker we make is based around our unique AEROFLEX bass topology. A method of extracting the most clean and accurate bass out of any cabinet size - be it a full size floorstander or the height of a CD case.

All of our loudspeaker cabinets are built in Sheffield, England with final assembly and quality checking done in house at our base on the Wirral.

We also use the highest quality crossover components and drivers available; not to mention the hundreds of hours spent tuning both by measurement and listening tests.

We hope you enjoy the final result!


AEROFLEX is our unique bass loading method that enables even the most compact cabinets to deliver clean, accurate bass.

Ported or reflex speakers, as they are often commonly known, re-use what would otherwise be wasted energy from the rear of the bass driver to boost the low frequencies.

Unfortunately in most systems the size of the port is not adequate and at high continuous volumes or even during short musical peaks unwanted noises and distortion occurs.

By utilising a much larger and longer port system AEROFLEX drastically lowers air velocity, properly controlling the driver throughout its stroke. This greatly enhances dynamic range and ensures the speaker produces the same tonal balance at both high and low volume levels.

As the port is built into the cabinet itself structural rigidity is also greatly increased, in turn improving the quality of the midrange.

High definition crossover design

The electrical crossovers in all our loudspeakers use only the highest quality components from Mundorf of Germany including audiophile grade capacitors, pure oxygen free copper coils and metal-oxide film resistors.

The use of such high quality components ensures that signal integrity is preserved from beginning to end and your music sounds as it should.

High fidelity drive units

All of our loudspeakers feature drive units designed to deliver music as free from distortion and colouration and as naturally as possible.

M and P-series speakers all use tweeters from renowned manufacturer SEAS of Norway. The Sonolex coated fabric diaphragms provide a detailed yet smooth performance that is easy to listen to for long periods.
