acoustical stuffing / sound dampening subwoofer cabinet REL BRITANNIA B1 subwoofer
Hello,
Quick question on acoustical stuffing / sound dampening in a subwoofer cabinet.
I am the 2nd owner of a REL Brittania B1 subwoofer.
Opened it up, and NO stuffing. A bit surprising. My guess is the original who was a dumb &*(&#$ removed it.
I am guessing there should be some stuffing in the cabinet.
IF SO, I am looking for recommendations as to how much to put in the cabinet and where.
THANKS for the help!
Please see pictures for view of interior of cabinet. Bottom-Middle- Top pictures
FYI--- Interior of cabinet is approximately 13” x 15” x 19”

My experience with any type of stuffing on a ported or vented box is closer to Dukes. It isn't always about the slight changes in effective cabinet volume as much as it is the dampening effect and the amount of output or cancellation because of wave front cancellation inside the box. On a ported box, I personally like 1.5 to 2 inches of unfaced fiberglass glued to the paralleled walls. It does a great job. Some of the foam type products mentioned do a very good job for dampening also, but be aware the more dense or hard the surface is, things start to change from effectively enlarging the box to effectively making the volume less. Good luck with all of this. Tim |
I haven't used other software, but if you are serious about building your own subwoofers, Bass Box Pro is really the best. You don't have to buy anything. It's up to you if you are really picky about how a sub performs. You could just buy a SanSpeak or Morel subwoofer. Then do dynamat damping on the interior walls, and then spray-glue some Acousta-Stuf Polyfill on the inside walls. Like timlub said, the stuffing will damping some of the peak that happens right before frequency roll-off. This might help work with some of these other subwoofer drivers. |
If you're still looking for possible drivers, the Rythmik Audio appears to be very nice: http://www.rythmikaudio.com/DS1200driver.html The specs say the DS1200 works fine in a 3-4 square foot vented cabinet. I don't know the pricing, but you can contact them. They are in Texas. |
Yup, Rythmik woofers are very good. The 12" is offered in two versions---with an aluminum cone, or a paper one, your choice. For really high performance, the Rythmik woofers can be used with the company's dedicated servo-feedback circuit plate amp, 370w or 600w. For use in a sealed enclosure, 1.5-2.0 cu.ft. is recommended. A lot of Maggie users are very happy with their Rythmik subs. Jim Salk offers his top model speakers with Rythmik subs built in. |
