Noobtastic14 Posted June 11, 2008 Report Share Posted June 11, 2008 (edited) i THINK i can get this in, and would be more cost effective than two 10s. specs: Double Baffle 4.5cuft Net internal volume two 2x18" slot vents total 72sqin of port 40hz tuning. Designed to go behind the rear seats firing fwd sealed off from the trunk. Music preference for this enclosure is Rock/Double Pedal with the woofer seeing ~1200-1500wrms Just looking for Approval/Disapproval from some of the expert box builders. -Drew Edit: just initial draft design, some changes need to be made such as increasing height to compensate for the outer mounting ring of the woofer.

Boon Posted June 11, 2008 Report Share Posted June 11, 2008 Looks pretty good, maybe do 1 big port for the sake of less turbulence? Quote 10.x volts fo' life! Link to comment Share on other sites More sharing options...

Decaf Posted June 11, 2008 Report Share Posted June 11, 2008 and ur tune frequency wont be exact because the bottom of the port extends beyond the top, so lets says its tuned to 40hz... include end correction factor if you havent + the port extending at the bottom and its prolly closer to 36-38hz sweet design and i like two ports, i like the symetry of it Quote Link to comment Share on other sites More sharing options...
AI James Posted June 11, 2008 Report Share Posted June 11, 2008 4 cubes is tiny for an 18 Quote Link to comment Share on other sites More sharing options...
meade916 Posted June 11, 2008 Report Share Posted June 11, 2008 your better off doing 1 4" x 18" port then 2 2" x 18. Those are a little too thin of ports and will probably make noise.

Noobtastic14 Posted June 11, 2008 Author Report Share Posted June 11, 2008 (edited) hmmmm... i'll re-draft a single 4x18" port version. if the tuning frequency drops a few hz i wont be sad, same effect as the distance between sub/up port/back and the tailgate in an SUV right?? whats a good size for a single 18? reason i opted for 4.5 is because i have my 15 in a compact 2.6cuft box and LOVE the punchy tone it has. -Drew Edited June 11, 2008 by Noobtastic14 Quote I am a United States Military Arts and Crafts Professional.

PaulO2288 Posted June 11, 2008 Report Share Posted June 11, 2008 I wuold do a 15 rather than an 18" in a trunk. I would still try to do the 2 10"s or 2 12"s though. Even if they are level 3's its still 10x better in my opinion. Your trying to stuff 200lbs of shit into a 5lb bag lol Quote Link to comment Share on other sites More sharing options...
