Sonosub is 18.5^3 tuned to 15.5Hz. Stands about 7' tall. Will be powered by an EP2500. Sounded very good off my 800watt amp. Shook the crap out of my house. Triple baffles top & bottom with a single 8" port. He's picking it up this afternoon, and his wife should be rather surprised as she has NO idea :laugh:

They're not "pretty" but they provide TONS of LFE....

I would think about cutting off the bottom of the little feet and attaching them to a circle cutout painted black or carpeted and the enclosure would then rest on that flat surface instead of those tiny little feet (and it looks like only three of them?

It only weighs about 150#'s and has (4) 1 1/4" hardood dowel legs, so it's more then sturdy.

Nothing really to look at. Cut out 6 end caps, make some inner supports for the port, do a big *** round over, so it's sort of flared. Line the tube with blanket batting, drop in the end caps, glue/screw/silicone.

Hardest part was wrapping it in the cloth :furious:

VERY common for HT subs. My 15" RL-P's are in 10cubes each...

Feet are fine, and look beefier in person. Plus the only real weight is the sub and it's at the bottom. I've built a few of these and this one is plenty solid. Bottom plate would have made it even harder to try and move around. It JUST clears the ceiling when trying to tip it and move it.

Normally you "try" to hide them in a corner, but there's no hiding this thing...

how do you actually make something like that? whats the whole tube consist of?

so the tube is cardboard? are you serious?

mlstrass
04-27-2008, 06:56 PM
Yep, concrete from that's 1/4" thick. Has no real right angles inside, so the pressure is distributed throughout the enclosure. HT guys have been doing them for years. And they're a TON lighter then an MDF or BB enclosure. My BB enclosures are 200+ pounds each...

not like regular cardboard,more densely packed, very sturdy without being worried about flex.

I'd be more concerned about the damage it will do to his house, seriously.

My 15's have broken light filaments, knocked out my projector bulb ($300 accident :verymad:), and knock **** off the walls all the time. And it's just the way I like it :crazy:

No they're not made of concrete. It is a concrete pouring tube for pouring columns and such. It's made of a dense and thick cardboard material and the cylindrical shape helps increase rigidity.
