A/V-3RS?
« on: 11 Mar 2009, 02:53 am »
I really like the design of the A/V-1RS, the idea of the omnipole surround, and the way it integrates visually and functionally into the room, but the only knock on this speaker is general lack of output as it's a small surround speaker, and that some people prefer the sound of the O-3 for a beefier sound coming out of the rear.  The A/V-1RS is a great design for a smaller theater or for integrating a theater into a living space.  What are the chances of a new design for a larger version of this speaker with additional, larger drivers for those of us that are building serious theaters?  How about stacking a 6 1/2" or an 8" driver on both sides of the current configuration, or even aiming these woofers off to the sides or out towards the room?  I like the low profile of the speaker against the wall, but it could easily be twice as wide, a little deeper, and a little taller and still be visually acceptable, say 30" wide by 10" deep by 18" high.  As long as the speaker is above shoulder level and has a relatively low profile it shouldn't really matter how big it gets as far as I'm concerned.  The A/V-1RS is a great speaker.  I built a pair a couple years ago for a friend and they are very happy with it.  I love the design and I just want a little more... always a little more.  Our receivers have just as much power for the rears as they do for the fronts.  Why not use it!!!  I could go with something like the O-3 but I really like the design of the A/V-1RS.  Anyway thanks for hearing me out and if anyone else would like something along these lines please chime in!

+1, 2 x 6.5" would be enough. What is needed is something that will hit a very solid 80hz easily and with high output for home theater. A lot of the movies these days are now mixed with very aggressive surround in them.

I think another variant is warranted, would be nice to use a NEO in the design as well.

Hmmm, I'll give that some thought.

Keep in mind that the A/V-1RS is about 90 to 91db sensitivity already. Using a pair of the M-130/16's with no baffle step loss (wall mounted) would drive sensitivity into the 93 to 94db range. So the standard GR-T3 and even the Neo-3 wouldn't be able to keep up.

In order to keep the response balanced, and not tipped up in the lower end, the tweeters response must be higher than the woofers as it looses off axis energy as frequency increases and the upper frequency ranges are easily attenuated by the reflections.

The only way I could really add a second woofer is if I wired them in series and added a cap across the terminals of the outer most woofer. This would allow only one woofer to cross to the tweeter but they'd share the load in the lower region. The only real gain from this would be power handling.

The box could be made deeper (double the air space) and it could be ported if you wanted it to play down lower. This could be done with one or two woofers but sure would make the box bigger.

How about stacking a 6 1/2" or an 8" driver on both sides of the current configuration, or even aiming these woofers off to the sides or out towards the room?

It doesn't really matter which way they are aimed if they are playing in an omni direction range.

The easy solution if you want more low frequency output is to add a sub. They do play low enough to reach a sub you know.

Hey Eric that is very simliliar to my future setup. I bought 3 Neo 3 non deep cup versions.

Will you build the subs seperate from the sealed LCRs?  Are you going OB sub or sealed?

I like the idea of three identical monitor speakers up front. Will be sweet when its finished.

I don't think the non deep-cup planars will work with this network as designed. Danny?

The two different tweeters require a different network.

Sorry for the confusion. My speakers while very similiar are the AV-3 Neo's an oldy but goodie ;).

I haven't actually been able to listen to them yet as the wife is against more speakers in this house and I have to wait until we finish building our new house next year.

My system is 7.2 and I use a 3rd sub (nothing special mind you, 4 - 8" dayton units iso. loaded) near the rear of my theater. Granted, mine is a dedicated theater and I have the space for it behind the couch, but I really like the sub-surround reinforcement in the back. I can't foresee getting rid of it.

Do you send the full range signal to the rear speakers and supplement that with the rear subs, or do you have an external crossover that high passes to the rear speakers and low passes to the rear subs?
