Default Largest Sonosub yet!!

Just finished a third sonosub... largest yet!!

and , I've gotta say, with both these and my BG's, I've reached the ultimate... no electronic tone enhancements and stable, clearly defined bass (with proper room placement) down to 20 Hz or so @ 110 dB... with very low distortion... nice!!!

Highly recommended, and built for ~ $150 (mostly the xover caps and inductor)...

Don't you have some spacing of the driver off the floor, to allow the driver to breathe? Rule of thumb is that the Sd should be less than or equal to the opening area. What driver is that, it looks car audio?

Default big ole' sonosub

David got it right... it's a Kicker Comp C-12... got 2 of them when Circuit City cleared their stock @ 2 for $75... couldn't pass them up. Not the greatest driver around, but it fits the bill here.

Driving it with 1 channel of a modified Adcom 555 II (other channel drives the PE Titanic sonosub on the other side of the room (you can see it in the background of the pic, left of the lamp). It's ported, tuned to 22 Hz extended bass shelf (see excel spreadsheet above).

and yes, it sits ~ 8" off the floor when operating.

Luckily, the glass cabinet sits next to an exterior block and brick load bearing wall, so the contents don't rattle around too much

Wife made the sock out of some $2/yd WallyWorld chair fabric... solves the sonosub finishing problem.

l8tr...

John, looking good! Are you using it for home theater or 2 channel?

dunno yet... wife and kids have to be out of the house b4 I crank it THAT loud... according to the spreadsheet, it should be down 3 dB @ 108 spl power limited (but we all know about calculations)



BUT... with both sonosubs and the mids on the linesources running, organ music, things like "Gates of Kiev, Mussorsky", etc. are downright frightening even at 100dB or so.... you should see the cat run!!!

I'll have to run a sweep if I get some time alone in the house... unfortunately, 20 Hz is highly room dependent, so I might have to place the mic ouside the house to actually detect it

Evan
It's for 2 channel, but I have 2 more (one isobaric loaded) up above the garage for the HT... augmenting my old heavily modded Infinity RS II's
