Lord Dukk,
I have 4 Fosgate Punch 15s (1 year ago version). Each is housed in a 1.5 cu. ft. enclosure measuring 16"X16"X16". Is there any way of porting each of these boxes for an extra db or 2. Please, I have a show on Sunday and I want to win(doesn't everybody). Your advice will be greatly appreciated.

Anthony,
It was Josh's idea to ask Lord Dukk. Dukk, help a fellow spl'er if you can.

Lucky I stopped by here today!

That box is kinda small, especially for venting. You can do it but the bottom end is going to drop off (no low sine sweeps!) and it may be kinda booooomy....

Anyhoo, SPL is the name of the game! I don't have TermPro right in front of me but if you drop a 4" port 6" long in each chamber, it will give you a 50Hz tune and should bring SPL up some.

Good luck! Oh bring a few T-shirts to stuff in the vents if your numbers drop (with boxes that small, I give no guarantees!)

And that's the bottom line, cuz:

Lord Dukk and everybody else who replied,
I understand the boxes are rediculously small but with the short time frame I had the boxes were already built and I just dropped them in. Dukk, I will try the ports, just because I'm a man of chance. Thank you very much and wish me luck.
