    IMHO,I would just go with as high current/high power(emphasis on current) solid state or tube amp. I tried bi-amping SDA's,and for me it just did not perform as I expected,,maybe I'm just impatient.,,I just prefer something like a Belles,BAT,Parasound in the solid stse realm,, and VTL,Manley,Quicksilver and Cary in the tube arena. Good luck.

    I biamp'd my 1.2TL a couple of years back with a set of modded Adcom 565 mono blocks on the lows and a Parasound HCA1000A and loved the improvement of bass, imaging and soundstage. Then I purchased a TriVista 300 and haven't looked back.

    I recently un-biamped my 2.3s. I'd been running a pair of pro amps (qsc and carver) and was very very happy. Then along comes a carver tfm45 for sale on craigslist. Unless something catastrophic happens to the new carver it's highly unlikely I'll go back to the bi-amp set up. The sound quality and soundstage is significantly better with one good amp imho. Another plus is that my local utility company probably won't be sending me a Christmas card next year with one less power guzzling amp in the mix.

    I don't have an amp yet. Im using Integra's 40.0 to push them with Klipsch's RC-64 Center Speaker in a dedicated room with double layer floating floor. 60/20/20 mix of blu ray viewing (I LOVE MOVIES) and Hd sports and xbox 360. When I was saying clearer I was refering to their current overall preformance.

    Alan there are many threads on upgrading xovers here in the forum. Search around. Some give step-by-step instructions.

    I have done 2 sets of crossovers recently for some 2Bs and 3.1 TLs, and I had very little experience doing this. It's not difficult with the people around here giving you help. The one thing they can't help you with is the actual soldering skills to do it. If you practice doing it a few times, you'll get it down though.

    "I'm yet to hear a Polk speaker that merits more than a sentence and 60 seconds discussion." :\
    My response is: If you need 60 seconds to respond in one sentence, you probably should't be evaluating Polk speakers.....

    I did my crossovers first then bought a new amp . . . I'm sure glad I did it in that order.

    Just out of curiosity, instead of an SDA bi-amp connection of hi-frequency versus low frequency via the external binding posts, has anyone ever bi-amped the stereo drivers separately from the dimensional drivers?

    You'd have to make internal mods to the speakers to be able to drive it this way. The load for the dimensional drivers, as the left/right difference signal, *might* benefit sonically if driven by a completely independent amplifier.

    Since the band-limiting of the SDA signal evolved with the product line evolution, even including the tweeters in the earlier incarnations if I recall correctly, the results would probably vary with SDA model.

    I have no plans to try it, and it was just one of those passing "I wonder if..." thoughts.

    Sorry for not responding sooner, I've been kinda busy fixing stuff. Were you able to find any of the SDA crossover upgrade threads?

    Considering that the SDA crosstalk cancellation signal is designed to produce sound at a dB level slightly less than the stereo drivers I don't think the above idea would work.

    B&W's do not impress me. If you don't feel comfortable doing the XO's yourself you may find someone near you to help. Posting your location will help you make some friends, and help you get your learn on. I also have done many XO's for Polkies. I don't mark up amy parts, and I charge very reasonable prices for Polkies. Don't give up on your speakers. Upgrade them. You would have to spend some serious money to beat SDA's. As for BiAmping money would be better spent getting one good amp. The money saved could be put to better use on upgrades, and decent wire.
    Ben
    Please. Please contact me a ben62670 @ yahoo.com. Make sure to include who you are, and you are from Polk so I don't delete your email. Also I am now physically unable to work on any projects. If you need help let these guys know. There are many people who will help if you let them know where you are.
    Thanks

    You really should find a way to upgrade your SDA's first.....take Ben up on his offer. If at that point you still don't like them by all means get those dry, sterile, finger nails on a chalkboard B&W's.

    You might find a friend in that area. If you can't all you need to do is remove the XO's and ship them. It is an easy endeavor.

    Ben helped with both my TL'd SDA-2B's and SDA SRS 2's and mailing to Ben is a great way to go if you don't want to tackle it yourself.

    I agree that upgrading the crossovers first seems to yield the highest payback for level of investment. I've upgraded about 10 components since and the speakers have NEVER been the weakest link since upgrading.
