I have a question on this. When I use the equation on JL's site for a slotted port, I get a shorter port if I use a smaller Height. So for a slotted port is it smarter to use the whole side, or just use a smaller slot on that side? For instance if he put in a 2" Width x 6" Height port, tuning to 32 Hz would be achieved at 15" depth. Correct? If so, and there are no negative port noise effects, I'd rather put this in mine than a snakey port. P.S. I'm trying to build my box also and still in the research stages. Stumped on the port.

I'm guessing 29.5 in. But I'm curious how others will break it down. I used JL audio's equation to do this. http://mobile.jlaudio.com/support_pages.php?page_id=165

Research led me here, and i hit the jackpot on answers

I tried to read the threads on how to make a slot port and etc. etc. I tried to use the ones on the net, but people keep saying they are off. So if you happen to have microsoft excel, you can use this on and plug and chug some numbers in to get your required port length. This is based off the equation on JL Audio's site and it also takes into account End correction. If anyone has any input or if the JL Audio equation is wrong, then let me know, I just wanted to do my port right. http://www.uploading.com/files/CFXVZ5QA/Sl...ulator.xls.html

I'm looking at getting 2 with the 2 ohms. I like the Kicker ZX2500.1 It is 2500 watts RMS at 2 ohms. Works just fine
