I just finished my latest DIY sub that I call "The Bonecrusher".
All enclosure panels were constructed by laminating 2 pieces of 3/4 mdf . The vertical corners have a 1.25" round over . Internal dimensions are 49 x 18.5 x 25 for an internal volume @ 13 cubic feet. The exterior has three coats of roll on truck bed liner over 2 coats of high build auto body primer.
The active drivers are a pair of 15" Dayton Reference HF and the 4 passive radiators are Exodus Audio PR-18's with 1750 grams of mass per radiator.
For power I am driving the sub with one channel of my Face Audio F1200-TS . The drivers are wired for a 2 ohm load.
Excuse the photos , they were taken with my phone.
Poor dog, I bet he's not a big fan of it.Does he head for the hills when you fire it up? I don't subject any animals to that kind of SPLs including my dog, cat and, fish. However, nice sub! In that second picture he has a look like OH NO NOT THAT BOX AGAIN. ;D

lol , Thats my little sweetie, Kandy. I have a pair of Weimaraners . They both want to get in my lap when I am running reference levels or above but normally it doesnt bother them . In the second photo she was already back to sleeping.
This sub is exceeding my expectations so far but if I really want to shake the neighborhood I can always fire up my diy ported AV15X that resides in the opposite corner. With both running the amount of bass is totally awesome.
nice sub rb. i came real close to calling you up on my way to bike week in april to listen to those statements. i guess by the time thunder beach rolls around again in oct. you should be ready to build something new and let me buy all that stuff.

What was the cost for both subs? Was the diy ported Acoustic Elegance AV15 ie. did it come with the box, speaker and amp or did you build it from the ground up? They both look great, Im trying to convince my friend into a DIY project. He doesn't have alot of money, so far ive talked him into not wasting his money on a $100 b.b sub.

Bob , I completely built both subs. The AV15 enclosure is constructed of Baltic Birch and covered in oak veneer and then trimmed with solid red oak strips. The cost of this one totals @ 450 I believe.
The Bonecrusher is constructed entirely with dual laminated 3/4 mdf . I bought the passive radiators second hand so that lowers the cost a bit. The paint is roll on truck bedliner. I have about $640 in it.
Both of these are overkill for most "normal" folks .
I have The Bonecrusher dialed in now and this thing is an absolute monster. I watched terminator Salvation on it last night and everything in my house was shaking.
That's great. With those prices im sure I can talk my friend into it. maybe 2 12" or a single 15". Did you get the components from parts express? Do you have a parts list. ie. do we just need a woofer, mount an external amp and build a box. Is you box hallow on the inside or did you add insulation? sorry for so many questions, I really want to make one. If this is successful, nex will be bookshelves and maybe fronts. Im sure those will be more difficult though.
