Bandpass Enclosure

Why do you want to build a bandpass enclosure?

Call Audiobahns tech support 714-988-0400 they should be able to give you the specs. Also you may want to consider venting your trunk into your cars cabin. It will allow your trunk to breathe resulting in increased SPL in the cabin.

i would scrap the band pass box. I would use a sealed  or ported box. then i would take the 6x9's out of the rear deck, put them in there own box. then dyno mat or some other brand of sound deading for your trunk. lay it on thick the sides the deck lid don't leave a spec uncoverd. that should help you out. ported and sealed boxes are a lot easyer to build. and i think a lot better.Big Dave

I want a bandpass enclosure so all of the bass will be ported straight into the cabin.  I hate the thought of all that bass banging around in the trunk when it could be filling up the cabin.  I have 2 of them hooked up in a Dual Folded Foghorn box, which is similar to that Double Shot box on www.power4sound.com.  Just the 2, 10's are hitting disgustingly hard but my trunk is about to explode.  I already crushed a 6x9.  there is no way i am adding the other 2, 10s.  I would love to but the rattles in the trunk just wouldnt be worth it.  Thanks for all your help.4, AudioBahn AW1000x Subs

Adding to what has already been written above, I do not think a bandpass enclosure would give you the effect you are looking for.  As Speedwayauto and bberman said, deaden your trunk to relive you of some of the rattles, and use the openings you now have your 6x9's in to port the trunk into the car's cabin.  Leave the openings clear and cover them with a speaker grill that has no speaker in it, for example.  Good luck!

Some really good ideas guys, here are some more. A lot of statements about sound deadening the trunk. #1 good idea. Old Isaac Newton is right, each action has an equal and opposite reaction. You are losing this bass energy tht you should be listening to as it is being transformed into energy causing things to rattle. Solve this problem with sound deadening. Your speaker (6x9) probably blew beacuse of a distorted signal being fed into it that you couldn't hear due to the more powerfull bass form the subs tht play at the same frequency and also due to the fact that your subs were physically moving so much air that it caused the 6x9's speaker cones to move and distort. So if you want the rear 6x9's to work in the future, you need to isolate them from the shock wave of the subs (also known as speaker hats or baffles) and probably would be a good idea to cap off the 6x9's or engage a high pass filter and amplifiy them. Do you know what the term Bandpass means? Do a little research and I'm sure you will agree with most of the veterans and even newbie's that are responding to you that it is not the way to go. A sealed box or properly constructed ported enclosure is your best bet. As DYohn suggested above, you need to get the output of the subs into the cabin, concentrate your efforts here as well. Sound has frequencies, those frequencies have wavelenghts, the lower the frequency  - the longer the wavelength. If you want to enjoy as much sound as possible it is usually accomplished by pointing the subs to the rear of the vehicle. Listen to what these guys have suggested above, they are right and eliminate the bandpass idea.Top Secret, I can tell you but then my wife will kill me.

yes a band pass box is not a good choice. trust us use a sealed or ported. face the subs to the rear of your trunk, and as far back as possible. building a band pass is very hard if your not an expert. ported and sealed can be build by a novice following plans very easyly. good luck with your project.Big Dave
