if u want a box design pm me lol, but i hope i didnt offend ya man it just seemed like you were acting better than everyone else.. maybe its me.. if so im sorry
but the port wouldnt be that long...

Ok, since I don't know how to design boxes, I'll let you...

We need 8.0cu^ft after displacement of port and woofer. 150sq^in port tuned @ 28Hz. With 2,000W rms.

So, what is the length of that port.

I know the answer... LONG, real....LONG!

if it was me.. I'd raise the tuning frequency upto 32-33hz, downfire the woofers and port.. and go for 100 + sq inches of teh vent..

OR

put some funky pups in there..

well... if you build the port as a slot using 2 enclosure walls... around 49" long

if you dont' nearly 55" long

I WANT COOKIE!

not disrespecting the quality of his work. Just saying that the customer had a problem and when i suggest an answer i get smart *** remarks.

Smart *** remarks?

Ok.

Anyways, the customer asked for 80sq^in, 28Hz tune, 8.0 after. We recommended 70sq^in because the vent velocity was very, very low with the power he was going to be running. (2,000 rms)

Then he and I stated what we thought of the woofer. No one on the net liked that response. Other said 125-150sq^in port. I checked.. The enclosure would be over 14cu^ft before displacement. Which I'm not sure if Manny even has that much room in his vehicle. Plus the port would be for example... 15" x 10" x 58" L

Building a port that large, that long in an enclosure would be tough. Which means we'd have to charge the customer quite a bit more. But that isn't the point.

Imo, the enclosure isn't built incorrectly. we're so sure of that, we're going to build Manny another. As soon as he figures out what he wants to do.

I do have (4) brand new 2005 XXX 15's sitting at the shop. We should throw those in for a comparison test.

But like I said on this board before in other threads...

"They're very loud, no doubt.

It's not that they didn't have a low end. Because they did. They just don't have the authority like other woofers with ALOT of low-end. It's authority is 40Hz, no doubt.

GREAT F'N woofer for the money, no doubt!

I recommend them to anyone!

I really hope they break in and start dropping low with authority. With that said, it will be a forced to be reckoned with when it comes to the subwoofer market. The high frequencies are brutal. Match that up with some vicious low-end. Right there you have an unbeatable combination."
