I had a set of Cresendo's, I see ALOT of people running them at the contests, but the sound shop that I am sponsored with had Digital Designs! I blew a Cresendo tweeter, and replaced it with a DD tweet. You could hear the one door sounded sooo much better than the other door! I got all DD! They are a little more, buty not crazy, I've seen some crazy competition sets go for $600 for just 1 set, but you can find DD's for about $50 ea.! Well worth it! Now I run ALL Digital Designs!!!
I have two DD vo 8''s, two DD vo 6.5''s, two DD 5.25'' 3 ways, and 2 DD B2 super tweets, on two 4 channel amps. One amp is for the 6''s and 8''s set on mid bass, and the other amp is for the 5.25''s and tweets set for highs.....
And EIGHT DD Redline 12''s on a DDz2
