RooTxBeeR Posted August 14, 2012 Report Share Posted August 14, 2012 (edited) So I guess my design wasn't good enough. I didn't think to much of it till I got the extra baffle on because that does effect the port. But it just seems like my sub should be playing lower. I am tuned to 29Hz, and anything from there and lower, is barely loud at all. My hole purpose of this build was to be able to reach down into the low 20's so I can get a feel for it as a daily driver and to see if I liked it at all for future preferences. From what I have learned on this forum, I believe I designed this properly, did I do something wrong?

notorious97200 Posted August 14, 2012 Report Share Posted August 14, 2012 2.5 ft3 for a 15" sub ? Been told by the owner ? I'd rather have a bigger box and less power !!! I've never seen any 15" liking 2.5 ft3 ported. At least 3ft3, but that's on the small side !

Joe X Posted August 14, 2012 Report Share Posted August 14, 2012 I was told by kevin himself since i am running almost dbl rms, to go 2.5Cu That's to prevent it from bottoming out. Some modelling may help you. Also you have checked sub,/port up but the port height suggests the idea was sub front/port up. Quote Link to comment Share on other sites More sharing options...
Skullz Posted August 14, 2012 Report Share Posted August 14, 2012 Way too small for a 15" regardless of what someone says, you want at least 3.5cf to start and go up to 4.0cf depending on your goals.

RooTxBeeR Posted August 14, 2012 Author Report Share Posted August 14, 2012 (edited) It is indeed portup/subup, As far as port dimensions, I have always gone off of the height of the port being if your looking at the top of the box, so the depth of the outer dimensions on the program. i thought it might be a bit small, guess I was right. Edit: I was told this by the owner of the company, so I thought that was the best place to ask for the design on their equipment.

You are also at 1" from the sidewall so the port length is 44" so tuned a bit lower. Edited August 14, 2012 by Joe X Quote Link to comment Share on other sites More sharing options...
