Well right now i have 2 dx 12's in a sealed box (.88 cu ft). and i got plans off here for a iso push pull bandpass box, but i was wondering if this would be louder than what i have now?? i thought i read some where that push\pull type enclosures dont make it louder, so i was wondering how this design compares to the sealed box?? Grrr.... i have been debating over this for awhile, and i still dont know what to do! a girl at work has ONE! JL 10W3 with 250 watts going to it in there "DB monster" box, and it beats my subs with 250 watts of power!!! i almost cried... also how would a bandpass box compare as well?? thanks for your help!!

The Iso-Push Pull Bandpass will be significantly louder than the sealed enclsoures. This enclosure will have a gain of 6 dB over the sealed box so the power needed to play these subs at louder listening levels is greatly reduced. Plus the cone displacement is kept within the drivers specifications and there is less of a chance of damaging the woofers' suspension. Most bandpass enclosure do not incorporate "gain" into their design. They may strive for a flat frequency response instead. You can detect this when you see a design where the volume of chamber 2 (which is the chamber that receives the ports), is only half the size or even much smaller than chamber 1. Thank God for box programs!!
Happy Bandpass Box Building!! ( hint, hint..)

I can vouch that the ISO push-pull is LOUD. It is a nice box, and polk should manufacture them with plexi windows hint hint. This box in my car with 400 watts rms@2ohms moved air, and caused passenhgers to shout turnit down a lot:cool:
