I have a 10" woofer right now, do you think I can use a spacer to fit it into a Bose box?Which RF do you have (what size). I know the Bose box is 8". I think the Burmester box is 10" (please confirm). But I have not seen any Burmesters boxes for sale (at least not on eBay or any other resale). Have seen many Bose boxes for sale at eBay.
If you have the 8" version of the RF, you'll be able to fit it with a 1/2" ring spacer. I used to have the RF in my Bose box, which I fit with the 1/2" spacer. I moved to an Audison APS-8D since then, and selling my RF on eBay.
