The only manufacturer of active loudspeakers with internal multi-input remote controlled preamp and DAC.

The first UK specialist hi-fi manufacturer to stop CD player production in 2006

AVI is the only manufacturer to offer a complete Hi Fi system in a compact pair of speakers.

Everyone knows that active speakers are better than traditional separates, but they aren’t much use unless, as ours do, they include a multi-input remote controlled preamplifier and DAC.

ADM9Ts have two digital inputs and one analogue, they come with a remote handset to control them.

A specially designed Sub woofer is also available, making them perfect for Movies as well as music.

All you need is a TV set and a digital source and you can be rid of an awful lot of clutter.

One box solutions and passive speakers cannot deliver!

Approximately forty years ago Wireless Word published an article entitled Dynamic Range Versus Ambient Noise. In order to reproduce accurately the full dynamic range of music they speculated, 1000 Watts would be required! In those days it was an impossible task and not really necessary because records had to be heavily compressed to avoid mis-tracking.

Digital recording changed everything, yet many well regarded amplifiers are still incapable of reproducing music at comparatively modest levels without a considerable amount of clipping. They are distorting, so not really hi fi. Hundreds of Watts are needed for musical peaks if clipping is to be avoided.

Cutting edge electronics now come from the Japanese giants and in the shape of AV processor/amplifiers They are considerably more powerful than most specialist hi fi.

Many so called one-box solutions cost a great deal more than ADM9Ts yet simply cannot reproduce the dynamic range because they don’t have anything like enough amplifier power.

Our ADM series of speakers have been a tremendous success, but we wonder how many realise that in part, the massive advantage they have in clarity, is as result of having enormous power reserves for musical peaks. Watts don't necessarily make the sound louder, but they do improve clarity.


AVI Neutron Five 2.1 system
See December 'Sound On Sound' Magazine for a full review!

AVI speakers are the perfect solution for your modern digital media :-

Modern: No more multiple box systems, just two speakers and a subwoofer

Versatile: Accepts digital signals from all TV, satellite receivers, computers, streaming devices, Blu-ray DVD players, games consoles etc.

Flexible: Can be used to provide front left and right and LFE as part of a 5.1 or 7.1 system.

Better sound quality: Three powerful 100 Watt amplifiers for the dynamic range and bass extension necessary for modern movies,TV programmes and games, plus greater clarity and neutrality for the finest music recordings. It is not possible to do justice to modern digital media with low power amplifiers, 25 Watts is less power than you get in modern TV sets!

Simple: Remote controlled with a digital display to show volume level, sub frequency and level, input selected and mute.

Affordable: Unique “all in the sub” electronics saves considerably on manufacturing costs and retail price compared to old fashioned multi box hi-fi.

The hub for all your media: The AVI Neutron Five 2.1 System comprises a pair of high quality 5” passive two-way speakers finished in a lustrous piano black lacquer and a special subwoofer which has three 100 Watt power amps, one for each Neutron and one for the 10” sub driver.

The subwoofer also contains a remote control preamp with one coaxial, three optical digital inputs and one analogue. A digital display that shows volume position, input selected, sub frequency and volume setting as well as mute is on the front of the sub. The sub setting is remembered for each individual input.

There is a great deal of video media with surround sound available; HD TV broadcasts, Blu-ray DVDs and games. The Neutron Five 2.1 system is ideal for use in a home cinema system.There is a handset button marked AV that selects fixed gain on the analogue input. This can be connected to the front left and right preamp outputs of an AV processor, the LFE output from the processor connects to the dedicated LFE input on the subwoofer.


AVI ADM9Ts

After four years of production and great success, we’ve updated our flagship 9.1s. Applying knowledge gained from development of the Neutron Five 2.1 System, we’ve taken advantage of recent advances in technology.

ADM 9.1s were cutting edge. The 9Ts are even more so. We’ve re-designed the power amplifiers, DAC and preamplifier boards for better performance and improved firmware to facilitate use with AV processors.

We’ve also given the 9T’s a new handset with a more durable finish and a button marked AV that selects fixed gain on the analogue input. This means that they can be connected to the front left and right preamp outputs of an AV processor. The special high power 10" ADM sub has an LFE input as well as the normal adjustable filtered, music input and both can used without need for switching.

All AVI products are made in substantial batches on modern automatic machinery in the UK and this together with our speedy adoption of the latest advances in technology means we’ve been able to to make these improvements without increasing our prices.

The ADM9Ts measure 31 x 20 x 24 cms and comprise of a fully active pair of speakers with 2 x optical digital inputs, one analogue (with fixed gain facility for use with AV processors) and an output for their own purpose designed sub.


There is a new article on the AVI Blog entitled Nobody Understands Bass which explains it all


HDD Audio stands for hard disc drive audio. The website aims to be the number one source of information for people looking to embark upon a computer-based hi-fi system, and help people to get the most out of music stored on their computers, iPod, hard drives, etc. We hope to provide advice in plain English as so many other websites perplex newcomers. http://hddaudio.net/
