BassJunkie Posted November 5, 2009 Author Report Share Posted November 5, 2009 Slot port it is.

BassJunkie Posted November 20, 2009 Author Report Share Posted November 20, 2009 11.16 cubes before displacement. about 10.1 cubes after displacement of subs and bracing. Any thoughts on this type of port? Not sure exactly how to calculate it since the bottom half of the port is shorter than the top half, but I'm sure I can get it figured out. Or if anyone is willing to help me pm me. the 18's like 5 cubes each so 10 cube common chamber after displacement. They need 80-95 sq inch total of port opening to be low end monsters. i would tune at 30-34hz I'm really delaying my build because I've had so many different ideas on boxes and I want to pick the best one before I start chopping up wood to only find out its not going to work.

Hmm interesting great minds must think a like. This is how my design looks for my 18s however im going for 13 cubes after sub, and bracing displacement. Cant give you any feed back cuz I barely bought the wood but if I finish first I'll let you know how it goes.

Boon Posted November 21, 2009 Report Share Posted November 21, 2009 That port fails terribly. Are you sure you're really up to doing a wall? Quote 10.x volts fo' life! Link to comment Share on other sites More sharing options...

brewer_brewer Posted November 21, 2009 Report Share Posted November 21, 2009 it looks like it wouldn't even act as a port, more of a hole in your box why not extend the box to the ceiling (hence the word, WALL) and then put a regular port up top. would also give you a bit more displacement since you only have about 5 feet a sub (small for an 18) Quote REFS http://www.caraudioclassifieds.org/forum/itrader.php?u=2026 http://www.stevemeadedesigns.com/board/topic/44535-official-brewer-brewer-feedback/page__p__625998__hl__brewer__fromsearch__1entry625998 "you're not allowing natural selection to work, you're like the guy that invented the seatbelt" Link to comment Share on other sites More sharing options...
