Re: How much "Bigger" do ELX towers sound compared to the Sierra LX?
I have both the LX and ELX RAAL Towers (started life as the v1 RAAL Towers). Currently have the LX in my office and Towers in my main system. I did put the LXs in my main system for a week or two when I first got them.
The LX are definitely incredible speakers. The bass, as you know, is surprisingly good considering the size. The Titan tweeter is no slouch either. I could probably live with those as my main speakers (in fact, I did buy them to take to our vacation house in Brazil but still haven't got around to that - much easier to get on the plane than the Towers :-)).
That said, the Towers are overall the better speaker, IMO. Particularly in the mids (as nate mentioned) and highs -- I prefer the RAAL to the TITAN, even with rock/metal which is what I primarily listen to. The Towers are more efficient, as well, so less power needed at equal volume (so more headroom).
Are you close to Ascend? If so, see about arranging a demo. Otherwise, I guess you could always order a pair and return them within 30 days if you don't find them a step up..my bet is you'll keep them.
