HiVi M6N 6" Aluminum/Magnesium Midbass
I have a little boston acoustics "subwoofer" with a 6" driver that has foam rot. It is a bandpass box with a sealed rear chamber and ported front chamber. Would this be a good replacement? A set of new foams is the same price as this driver is.

These are the drivers that seem to be the best in the price point. What is the volume displaced by the driver?
This woofer displaces 0.028 cubic feet.

Hello, I am an owner of these speakers, and was wondering if there is a way to get more bass from them. I have a 1" x 5" bass port and .72 cu ft box. Would either widening the port or adding a second HiVi woofer help extend the bass response? Thanks.
Right now you have two issues; the port size is far too small so you are essentially "choking" the output of the woofer. It is also tuned far too low as it is now (about 22 Hz) which will take a way a lot of the perceived bass response you should be getting. I would recommend replacing the port with a 2" diameter, 5" long port to bring the tuning frequency up to about 42 Hz. Adding a second woofer will not help with extension but it will help with output. You would need more airspace to make this worthwhile though.

Hello everyone and thank you for your help. I would like to use two drivers per speaker box and was wondering what size difference this would make in the enclosure? Also, will a 1 1/8" x 6.5" bass port work? Thanks!
The enclosure volume will double if you add a second woofer. That port is on the small side for a pair of these. In the recommended vented volume, I would use a 2.5" diameter, 3.5" long port for a tuning frequency of 45 Hz.

Trying to figure out if this will fit in my Acoustic Research M4 woofer.This is a older model. Or what speaker would you recommend for replacement. Thank you Chris

The ideal sealed volume is listed as .23 cu ft. Does the box need to be built oversized to account for the amount displaced by the speaker itself? If so, how much additional volume? Thanks
You could build the box to 0.25 or so to make up for it, but the woofer displacement will have almost no affect on the audible performance in a sealed box.
