seems a bit dodgy, but try have a look anyway...

I'm going to build a REAL transmission line for one of these woofers!!!!

just designed one now //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Few questions:

1. Why in the world would you fire 7 of them on the front and one up? It would make more sense to go bipolar and fire four forward and four back to pick up reflections off the back wall. There is no imaging from up firing, all that it may give is extra output. Tell me your reasoning if you don't mind.

2. What sort of slope are you using on the crossover, what attenuation and what kinda tweets?

only 7 woofers will fit on the front...

box position doesn't allow for woofers on the rear, as they are pretty much up against a wall...

7 woofers cant be wired to an amplifier in any reasonable way...

hence, 8 woofers, one of which is firing up...

um. thats a great explanation.

.....In that case, why are you set on using 8 woofers as it's a waste of space putting a speaker on top. Maybe on bottom if you run it in a 2.5 way and use it as a "subwoofer", but even then it's questionable. Why not six?

cos, what fun is 6? lol

Ok....

Anyway, you still didn't say what kind of x-over you were using.

12dB per octave at 4000Hz...

not filtering the woofers...

this isn't meant to be a SQ setup, its meant to just get loud...

Wait...what? You're crossing over your tweeters at 4000 and are letting your woofers play fullrange? With all due respect, do you know what you're doing? I'm not trying to be rude, but that makes no logical sense. If you wanted to get loud, just get some goldwood 12s and mids and throw in a horn tweeter. Slap 'em in a huge box and go, not something I'd do with decent speakers.

Those towers look very similar to the ones I'll be building soon...except mine will just be housing one 6.5" //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Gaaa, your towers will give you way better results //content.invisioncic.com/y282845/emoticons/up2something.gif.dd110ecf3ae4b76050d87598f2f8de7c.gif
