AI James Posted December 16, 2007 Report Share Posted December 16, 2007 rd audio alpha 18 shipped to me is $450 not that bad about the same as the btl but it has a boltdown spyder and vented magnet like atomic but after that dd im almost wanting to run the same setup in the blazer under the window line 15's but 18's in a wall sound so much better to me but i heard there about 600 a woofer vs 450 for the rd alplhas um the RD Alphas are NOTHING like a BTL, im guessing an RD rep or Steve from RD told you they were, they really need to stop the bullshitting of customers. Just do yourself a favor and look at the T/S specs on both before stating they are "about" the same. Quote Link to comment Share on other sites More sharing options...

johnnycat76 Posted December 17, 2007 Report Share Posted December 17, 2007 DD isn't too bad I have a few DD products but am I always looking for something better. (currently dissapointed with my system ) 153.6db is not that bad of a # for 2 15s. The last TL session I was at this guy with 4-9515s in a wall, 1 US Amp 4000k hit a little over 152. Here is the video. I would be happy hitting anything above 150, I'm still trying.
