Avantgarde XLR subwoofer connection

Yes, actually 2 pair of the SUB225s with the Duo Omega.
I run from my pre to a Behringer DEQ2496 ( for bass correction ) then to a Y adapter to feed the signal to each sub.

I have never been a fan of driving AG speaker this way.

I much prefer the speaker level into a sub for any 2 channel system. Especially with an UNO as the sub comes so high to meet mid. Don't you find that odd phase or textural difference annoying? You will find it hard to get decent image depth or believable soundstage that way IMHO.

Chadeffect, i agree with you, its difficult to obtain a good result with direct XLR connection, because it depends from preamp line output. I came back today to usual connection, using Transparent Reference between medium and bass-treble, instead of Avantgarde cables, and its better

Marco,

If you are in need of better bass, I would save your cash and find an amp with those characteristics you require and run the whole speaker from it.

You will have a much more cohesive sound. The UNO already suffers from the sub meeting the horn up high, so I wouldn't make an even larger difference in character by running subs with differing signal chain.

You will be in heaven when you find the right amp.

Right, i consider using the Model 3 as a preamp, and Pass Labs XA 60.5 for the Uno ( or maybe the Mezzo)
