mustang guy Posted May 12, 2014 Share Posted May 12, 2014 Niles has done it again. They have developed a subwoofer that is buried. I was looking at my crutchfield catalog and saw a diagram in the back, and thought, "why didn't I think of that?" I love the idea, but since we are real knuckleheads, we will of course figure out a way to do it bigger and better. I'm thinking an old cistern would be a great chamber for an inground IB. Here's the site. 2 Quote Link to comment Share on other sites More sharing options...

mustang guy Posted May 12, 2014 Author Share Posted May 12, 2014 (edited) About a year ago I actually priced 1/2" plastic to build BFM subs into a hillside. I couldn't come up with a good method to secure panels to one another. Perhaps something like this with a horn like a brass Tuba shape pointing straight up, and then an inverted bowl to keep critters and weather out. This has inspired me. Its raining like crazy outside, so I might as well draw a neat underground sub on Sketchup. edit: OK here is the IB chamber. The approximate size is 87 cu ft. Should allow for a nice sized driver or two. I am forgetting about the tuba shaped mouth, and just figuring on a driver or drivers mounted in a large pipe. I could use an upside down bowl idea like the Niles people, or go with more of an upside down J, like gas companies use. second update: I calculated 4 sub drivers of brand and model Kicker S15L7 Solo-Baric 15" DVC Subwoofer 2+2 Ohms. Using this chamber and 3 - 12" wide ports 27 1/2" long results in a 15 - 350Hz response curve, with some pretty flat max spl everywhere from 15 - 450Hz in the 130db range. Would be great for an outdoor movie... Edited May 12, 2014 by mustang guy 1 Quote Link to comment Share on other sites More sharing options...

Sancho Panza Posted May 13, 2014 Share Posted May 13, 2014 Looks like it needs about 3 racks of ribs. Dry, wet, or both? Who's got the rub & sauce? 3 Quote Link to comment Share on other sites More sharing options...

I would think it would act more like a port than a sound transmitter. 1 Quote Link to comment Share on other sites More sharing options...
