Avantgarde Duos: Omega or Mezzo?

The smaller room is too small for any of the Avantgardes - you need to sit a minimum of 10' from the tweeters for proper integration, and the tweeters in that case would be 12' apart if proper ratio is used - meaning that the small dimension of the room must be 14' or more.

As another owner has noted, the Duo Omegas have no practical limitation on bass extension; I find that the bass integration issue some cite is actually due to poor set-up, crossing the subs over too high, and/or setting subs' volume level too high.

Thanks Triode, makes perfect sense.

I've actually decided for Mezzos for the bigger room. Any comments on:

1- Placement away from walls
2- Amp matching - currently thinking of an Audio Note Jinro

Thanks!

Miguelito,
Placement is critical, first, you have to position for the best bass response in your particular room- could be tricky, since it might NOT coincide with the best position for the imaging. So you will have to experiment in your own room.
I can tell you though, that farther away they are from the back wall. the better the sound stage depth will be (duh!)
Amp matching- I tried a few, and not surprisingly, Lamm ML-2
SET amps are a match made in heaven. And it is well accepted choice from many other owners.
Owners also say, that Art Audio PX25 is another good choice, but comes with a warning- DO NOT deal with Joe Fratus who used to represent (actually to misrepresent) Art Audio, which is a British company, in the US.
I also tried Tom Eavans Linear A amp, which was good, but not as good, as Lamm ML2.
I heard very positive reports on expensive Audio Note amps with the Avantgardes, but this is not a personal experience

I second Maril555's recommendation of the Lamm ML2; magic combination with my Duo Omegas!

Indeed, the speaker position in the room that yields the best bass response will very rarely, if ever, also yield the most natural midrange, and the best sound stage and stereo image. However, that is very very true for normal speakers, i.e. drivers in a box. With horns, because the directivity of the high and midrange frequencies is controlled, the situation is much less critical. Placing the DUOs close to walls (back wall or lateral walls) is less problematic and in most cases will have only minor effects on the midrange and high frequencies. Beside being a natural amplifier, the horn also minimizes the interaction of the sound field with the boundaries of the room. Consequently, the most important thing to do is to move the speakers in the room and look for the position that gives the best bass response. Tilting and/or changing the inclination of the speakers will almost always solve most problems with the high and midrange frequencies.
