I just completed a BESL dual 10 sub. The inner case is 3/4 inch MDF and the outer case is 3/4 inch Oak. It uses two 10 inch Peerless drivers downfiring in a push pull arrangment and a 3 inch port. The sub is powered by a KG 5230 amp. Here are my thoughts on my new sub: Looks- Much better looking than the production models. It has legs and a nice top and looks like a fat mission end table. My wife gives it a thumbs up. Sound- I had a sunfire hooked up to my system and have listened to several velodynes. No AB test, but I think my sounds just a good as any of the mentioned model. Build- much better case than production models. Very heavy but super solid. Total cost- 700 dollars
