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”

Faital Pro makes some good stuff.  However, this woofer would not be a good choice for your REL box.  For one thing, the resonance frequency is very high at 45hz - making this a general woofer instead of a subwoofer.  Subwoofer drivers typically have a resonance frequency between 17hz and 25hz.  The second thing is the VAS on the Faital is only 1.06 cubic feet.  This woofer would not perform well at all in your 3.5 cubic foot REL B1 box.  I modeled the Faital in BassBox Pro and it really wants a 0.7 cubic foot box for vented, and it still would not give you deep bass like a normal subwoofer.  The Faital stuff is designed to have very high efficiency for pro audio sound - to be very loud for live sound concerts.

Both the Scanspeak and the Peerless would be highly superior choices.  I don't know about the Eminence, but I suspect it would be fine  The eminence is not in the BassBox library and I didn't have time to enter in all the T/S parameters.

I just did the model on the Eminence and it would work out just fine in your REL B1 box.  So, ultimately, any choice of the ScanSpeak, Peerless or Eminence subwoofers I suggested would work great in your REL B1 cabinet.
