ADM40s Imminent Most visitors to this site will be aware of the impending arrival of ADM40s because they've been discussed on the AVI Forum and the Facebook AVI club, so now it seems appropriate to give more detail and a background to their development here. Introduction It has been obvious for a long time that there is a worthwhile demand for a slightly larger and more versatile floor standing version of the ADM9Ts, but since these would have to be more expensive, we were determined, if we produced them, that they should offer significantly better performance. However, in the event, it has been so difficult to improve on ADM9s that we've spent a couple of years working on ADM40s. The exercise has taught us a lot and finally we've produced what may well be the finest sounding speakers money can buy. They compare with the best headphones for smoothness and clarity, but have the advantage that speakers have, of a lovely deep and wide stereo image. Without the price constraints of ADM9Ts, we've been able to design completely new floor standers that provide more inputs, a digital display, more bass and improved sound quality. ADM9s have almost certainly redefined Hi Fi, they've made expensive traditional separates redundant and given others a blueprint for the future and yet clones are only beginning to appear now, a full five years after they first appeared. AVI is an innovator and was the first British company to stop production of CD players in June 2006. We predicted the end of hi fi separates then. Description ADM40s comprise of an elegant, slim and comparatively small floor standing two ways measuring 90H x 21W x 31.5D. Small is crucial to good sound because the size of the box dictates how it radiates from it and also how it impacts on the acoustics of a room. Different boxes sound different and small is preferred because dispersion is better and cabinet reflections are less obvious. There are four optical digital and two analogue inputs, a digital display and outputs for one or two Subs. In the old days, passive three way speakers were regarded as the best that could be done, but we know now that even the tweeter/mid crossover is very intrusive and that the bass/mid, in our opinion unacceptably so. Therefore Active two ways are more pleasant to listen to and a different approach is necessary to get the benefits of three way without the irritating distortions. The ADM40s have been designed as a full range two way with a -6dB point of 40Hz, or to be switchable to a full three way, crossing over to a Sub (or two if required) at 100Hz. This extends LF output to well below 30Hz and gives greater mid range clarity and more dynamic range because driver excursion is considerably reduced. A full, active, 2nd order crossover at 100Hz has been built into the ADM40s which has to be extremely accurate because phase errors can amount to a metre or more! However our ears aren't very sensitive at such a low frequency, so unlike a big old three way, we don't hear it provided its done properly. This means that the internal AVI SUB filters are not used and that ADM40s, unlike ADM9Ts are connected to the LFE input. Electronics We've designed new electronics for the ADM40s and these give four optical digital inputs and two analogue. There is a discrete digital display that indicates volume, sub level, input selected and mute. Drive units The weakest link in any speaker is its drivers and because good actives sound better than passives by losing the sound of the crossover, it becomes more important to find the very best possible. We already have them in the ADM9Ts, or we thought we had, but after a considerable amount of evaluation we've found better, albeit at far greater cost. Scanspeaks normally appear in ludicrously expensive hi end speakers, which is not necessarily a good reason to choose them, but these are special, they have 50% more linear travel and the cleanest mid we've ever seen. Their tweeter is too, is the most beautifully transparent, smooth and detailed we've ever heard. Conclusion Small, very powerful, amongst the best sounding, comparing favourably with the best headphones, more bass on their own than ADM9s and better still with separate subs, ADM40s are the very embodiment of everything that matters to us and what we hope does to you as well. The signs are good, because all of the first batch have sold and quite a few from the second, so if you'd like a pair and haven't yet ordered, it is time to consider doing so because there will be a bit of a delay, but it's worth it. AVI Neutron Five 2.1 system
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.
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/
