Mating Quad 2905's with crossover and subs?

I have had a pair of 2905s for 5+ years with a steady progression of REL subs, starting with the 305s, tried a single B1, and then a pair of 505s. I recently added a G1 with a second one on its way. IMHO 2905s with a pair of REL G1s is a pretty awesome combo and a match made in heaven. You get a holographic midrange and the transparency only a ESL can provide with a visceral bottom end. Don't believe all the theoretical nonsense about the problems integrating ESLs and subs. Been there, done it and its magic.
I set the X cross over at 30 hz on the RELs. Be careful regd phase setting: 0 or 180 makes a big difference. The G1 has a remote so its a breeze to set up.
Whether its a Bach organ piece, Dire Straits or Patricia Barber, opening the window below 30hz all the way down to 20hz or lower is something to be heard to believe.
I prefer not to mess with an X crossover and have moved up the REL chain. Am really excited about the arrival of the 2nd G1.
Be happy to share more info by mail.
2905s plus REL HUGELY recommended.

Your dealer is a wise man. It's not easy to replace the Quads. Sadly I am also in the process of selling my 2905s . It's a long story and no reflection on the Quads. The integration with a sub, preferably a pair ,is pretty simple. I can't think of many speakers incl the upper end Wilson Audios that can match the deep and musically satisfying bass a Rel G1 can provide.
