enclosure design

I designed an enclosure I have no idea how to tune, I'm looking for dramatic SPL numbers from only 2 12s, any ideas? It was an experiment(to me at least, never seen the design prior) It resembles a normal dual driver sealed box, yet with a shared slot loaded vent in the center of the speakers on the front baffle..Jeremy

It's a box with a rectangular hole in the middle between the speakers?  Are you trying to find out how to build a port?  Did you read the forum rules about posting your equipment models etc. so this forum would know a little about what you've got to work with? Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Sorry about that, I'm pretty well versed with designing ported/vented boxes for x freq tuning, it's just this particular box I designed I'm kinda lost on because to me it's experimental(though I'm sure someone else has designed something along the same lines) - Anyways, equipment involved is as follows(please don't laugh it performs better than you think.) 2 L121P5 12" Sony Xplod's / 350RMS / 4ohm 1 Audiobahn A8000T monoblock with the subs presenting a 2 ohm load in parallel with 800RMS @ 2 ohm / 1600 ACH stock honda head unit with 6 disc alpine changer. 1996 Accord 2.7 V6 Gold Ed. any ideas on how to increase cabin gain, properly tune this box(4.66820 cu ft) would be most appreciated. I'm new to this stuff... Jeremy jeremy[at]uniksystems.com jeremy[at]powerprecision.comJeremy

Oh, forgot I have 12 speakers aside from the subs, the stock 1" dome tweeters on the dash, amplified by a crap amp, along with full range 3 way L-audio 6x9's, and alpine SVS for the front stage. Jeremy
