Hey...My current rig incorporates a pair of 1x12's that get all the way down to 29hz @ -3dB, so I;m set for low end...in fact, i have almost too much...I tend to cut my bass back a lot, and keep treble and mid alll the way up (Yamaha pb-1) I am in the process of obtaining a new power amp (crest 4801 or EW PL-1000) and was thinking...I'd like more high end. my last amp had a tweeter, and I think I got used to being able to get the highs to draw blood... and now I'm kinda lacking them. I like the sound of the 8x8 a lot, and was thinking that I may be able to add a 4x8 (a full 8x8 is too big, methinks) but - and afew BUT's - It only handles 250 watts. My 1x12's are 600 w a peice. And I'll have a big poweramp running it all...and the 4x8 is 8 ohm (both 1x12's are 8 ohm) - so I could run one side of the amp @ 4 ohm and one at 8 - but do you think the 4x8 can keep up without blowing up? the 1x12's are medium/low efficient...I just want to know what you think...and if you have any other suggestions for getting more high end. A 2x8? 2x10? suggestions? oh - what if I biamped, and ran the henry crossed over with, say everything below 100-120 rolled off? Would that let me push it louder? Or sound louder?, with less actual power running to it? Help!
