subwoofer enclosure mixing

[bm8998]

Thanks for the help , Kim. My problem started with the purchase of another car. My old car fit two bandpass enclosures perfectly. My new car only fits one enclosure. Now, my second problem comes about as i read the info. on this web site. BANDPASS OR SEALED???? I like the exagerated bass of a bandpass, but, I also like the clean tight bass of a sealed enclosure!! If I place one bandpass and one sealed enclosure will I have more complete bass or will they work against each other in certain frequencies. PLEASE HELP!!!

Because of the "gain" difference between these two types of enclosures and their rate of roll off, I don't think that using a sealed and bandpass enclosure together will work very well.
The other option is to use both enclosures and use a heavy duty switch or relay to select the type of box that you want to listen to.
If that is not practical, then build the single bandpass, and stuff the sealed chamber with half a bag of poly fill, and line the vented chamber with damping material such as a "quilting material". This stuff looks like a sheet of thin polyfill. You can buy this from any fabric store.
