Mating Quad 2905's with crossover and subs?


I love the 2905's, but I can't take their dynamic or bass limitations. Has anyone got any experience with crossing the quads say with a pair of REL's and a crossover (a Bryston Xover is what I'm thinking)? If so, what were your impressions, and at what frequency did you Xover to the subs?
I'm thinking I could get the dynamics out of the quads, if I were to pass the lows to the subs, and let the subs handle the bottom.
Any thoughts, remarks, impressions, or advice would be greatly appreciated :-) !

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.

Sunnyboy -

Your REL G1 is very encouraging news. I will soon be auditioning a couple of box speakers as possible replacements for my 2905's, but will also ask for a G1/2905 setup for comparison.

My dealer warns me about the impossibility of finding Quad magic in box speakers under astro sums of money, so I'm inclined to keep 'em.

Still, I do wish the Quads were more, ah, visually inspiring...

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.

fwiw, I have heard many a system with subwoofers over the years and never heard one I like.
Just too amorphous for me.
The same goes for equalizers/tone controls.
It's nice in theory, but my ears tell me something is always off or unnatural.

This even happens where the manufacturer makes the speaker and the sub. Case in point (all for speakers I owned):
Kharma 3.2, Wilson Watt Puppies, Apogee Stages.
