Active speakers will differ in sound. Of course they will, as speakers are the single most difficult part of the sound reproduction chain to get right, however differences will be less pronounced between monitors, as in general, they have all been engineered to be neutral, so the variations between such speakers will not be so pronounced as speakers that are designed to have colouration, ie hifi speakers in general. Some hifi speakers are designed to be neutral, as I suppose are the Kef LS50 (and I'm sure they're just fine BTW). Thus it can be said that monitors (ADM9s included) are generally neutral, or close too.
Again, AVI ADM9s are recommended so much because of the lack of anything else like them, as responses to my earlier question highlight. I would actually imagine that the LS50s would be quite a good alternative to the ADMs, but I've never heard them. The caveat with the LS50s would be that they would seem to need a fairly capable amplifier.
Under what definition of neutral is a frequency response that is -2dbs at 100hz and -6dbs at 60 hz neutral?
In my book that's not neutral. It's not even close to neutral. It's lean.
I don't think that AVI ADM9's are recommended so much because of the lack of anything like them. I think they're recommended so much because the marketing methods are similar to those used by Ivor Tiefenbrun for the Linn LP12 in the 1970's to 1980's. I'll start a new thread if anyone would like me to explain what I mean by that.
I would need a lawyer if I were to say what I really felt about that episode in the history of British hi-fi. (Assuming the mods even left it in.)
I once witnessed vile behaviour (by a then very senior member of staff at a Glasgow based hi-fi company) towards two innocent customers, at a dealership he was visiting (and that I used to buy from), that caused me to switch dealers and never return. As a result I have never bought anything made by that company.
However, the 'very senior member of staff' is still active in the industry. (And is now an even more senior member of staff at another well-known UK based hi-fi company). So that is as far as I can go.
Suffice to say the episode encapsulated the bullying style of marketing - in force at the time - far more vivdly for me than the famous phrase coined at the time by another company very close to Linn ...

I'd like to know more details! (i) What you say hasn't identified them, (ii) if it really happened you can't get in trouble!

Trouble is Ben, when did truth have anything to do with civil action being taken? If it really happened and you have plenty of witnesses, that have a backbone, then you can't get in trouble; might be closer.

What you say hasn't identified them
I can certainly narrow it down to a few people - indeed probably the exact one....

I think you need to be a little more specific. What are you refering to exactly?
The ADMs are very much recommended because there are little or no alternatives at their price, they are also very good. That's my standpoint anyhow.
Mac mini > AVI ADM9Ts
The AMDs are recommended by a very small number of people very many times, that does not make them very much recommended.........

I suspect that you did not understand my last statement.
Harbeth has been reviewed by What Hi-fi?
In their Russian edition.
(Page 75, January 2013)
Did they get five (red) stars?
final conclusion sounds like that "If you need fullrange big monitor speakers and have experience in systems setups hi-fi equipment pay attention to these,they have everything to reproduce music"

Ok,thinking abaut passive vs active ,searching web and reading this thread,to my mind poped an idea-ACTIVE CROSSOVER.The Basic idea is- make active speakers from passive ones just adding active crossover and power amp to excisting system,dissconnecting passive crossover from drivers and connecting to it power amps which is connected to active crossover,crossover connected to preamp .Like in this picture.
There is a very detailed description of converting passive B&W 801 speakers to active HERE. I've heard these speakers and thought they were excellent.
Thanks for a link. Now I am obsessed with this idea
I was refering to the frequency response specifications given on the AVI website for the ADM9's. Speakers that you said were neutral or close to neutral. They might be close to neutral for you. For me they aren't. They are on the lean side of neutral.
I'm with Mac on this one. Back on topic. I have some P3ESR's and i love them!!! They look beautiful too (especilally in Rosewood).
I'm sure i saw an AVI or an active thread somewhere. Can you AVI owners bang on about how good they are on that thread and stop hijacking others...........its soooooo boring.

Ah I see. I suppose you would need the see the whole graph to get the full picture, rather than pick a single frequency?
Is the -6dB figure not for the woofer alone and the -3 dB figure for the tweeter extension alone anyway?
What about the total system amplitude response of better than +/- 2 dB 100Hz to 20KHz?
That seems pretty good to me and S.O.S (and others) seem to think so also.
BTW, have been reading a lot of AS on the HUG - he is the god of common sense! I'll be off to Doug Brady to audition some P3ESR's soon as.
How did you get on by the way?

That is not what the topic was about. As already stated earlier in the thread, the topic was more or less exhausted after 6 posts.
