[QUOTE="Grant Conklin, post: 59780, member: 120"] Re: B&C Sub designs Hi Kip, I just ordered these exact same drivers for a project. I accidently ordered the 8 ohm version, so I'm hoping to swap them out for 4 ohm before getting started. I plan to build one of Art Welter's Keystone subs ([url=http://www.diyaudio.com/forums/subwoofers/185588-keystone-sub-using-18-15-12-inch-speakers.html]Keystone Sub Using 18,15,&12 Inch Speakers - diyAudio[/url]) which he says should compare favorably to Danley TH118. I'm going to try 1 or 2 other designs as well before settling. As for plywood, Baltic Birch is decidedly best, as you found. Art mentions using Arauco plywood ([url=http://www.araucoply.com/informacion2.asp?Submenu=1522&cat=1651&fin=1667&idioma=44]AraucoPly, MORE THAN JUST A PRETTY FACE - ARAUCO[/url]). I've seen this stuff in Menards, and though it's not hardwood, it looks to be void free or close to it. $40/ sheet for 3/4". It's what my first boxes will be made of. Check out Art's last post in the thread I linked. The SW115 driver will take a lot more than rated power, and the same may be true of the 18TBW100. Grant [/QUOTE]
