NEW HT sub project need ideas|opinons

[djman37 5,000+ posts]

I have an amp. Old school Kenwood BASIC M2A 230x2 @ 8 320x2 @4 .002%THD

Dual mono block. Might only use 1 side since the other is acting squirrelly.

I'll get a pic up soon of the living space. I don't have room for a huge @ss sub enclosure.

I'm thinking of 4 8" drivers behind the TV stand or maybe a powered setup across the fireplace, running the signal cable under the carpet or an unpowered unit with speaker wires under the carpet.

i've considered MAW12 or 15, 4 8" assassins, Dayton Quatro 12. I have a DD9512 to use, but it's dual .7 and the two eclipse 10's in my F/S thread http://www.caraudio.com/forum/showthread.php?t=204941 2 10" dual 4's.

Sealed for size, but with an interesting design would port in the low 20's.

leaning towards using the amp and making something non-powered.

Uhh ok...

Is there a question here?

just looking for thoughts or ideas. I've got an amp, and am about to build an HT sub.

Your post is weird. You don't want a big subwoofer but you will consider a ported design. Most ported designs can be big, but if you keep tuning > 20hz the box size is reasonable

but probably in the 5 - 6 cu. ft. minimum range.

You want a non-powered subwoofer? What does this mean ? A subwoofer

that operates with no power? lol

If you want to make a non-active subwoofer, powered by your mains amp,

this isn't a worthy investment.

I have a DD9512 to use, but it's dual .7

Post T/S parameters.

***************************************************************

Someone paid $255 for that amp.

If you can sell yours for $250, then buy a buttkicker BKA1000 for $250 {maybe less}

and that would make a nice HT sub amp. Jury is still out on it's 2 ohm

performance vs. advertised.

i'm really WAY too busy here at work to make a good post. I'll re-do it tonight.

is this for music in a room, or acctual movies?

thatll have alot to do with tuning and box size

what im doing is putting a band pass box on the floor in my closet, so ill have 22 x 22 x 14, and can put stuff on it

i sold all my stuff and am starting over small. I may just pick up the dayton powered 12 on sale on PE for now. After putting an HD newscast on the air, i'm tired.

i cant remember what vc they are but i had all 4 wired to 4 ohms.

what a total brain meltdown today. I ordered a Dayton Quattro 12" and will build sealed enclosure to start with for it.

Might take the advice and sell the amp that's been sitting idle for a couple of years.

fokker out.

I would highly recommend something along the lines of 4 Mach5 18s in a sealed box powered by a Behringer EP2500, it would fit in a small box and would be able to extend into the teens with authority //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

A behringer DEQ2496 would be a nice addition for equalization purposes

when you say small box how small are you talking about?

smaller than his couch?

i have a hard time seeing 4 18's in anything less than 8 or so cu-ft

and i dont think there is room in his living room for a monster like that.

6.951 cubic feet for a Qtc of .702

a box thats ~20" wide, 40" tall, and 20" deep would satisfy the space requirement, thats not unreasonable. You'd mount 2 18s on the front and rear or 1 18 on each side to reduce non-linear distortion and vibration, you could substitute it as an end table or cover it in leather and it can be an ottoman

wife SO wouldn't go for that. Quattro is on it's way.

For that size, I've got a Decware WickedOne in the garage. I could do a housewrecker if I wanted an all out bass beast.

Thx for the info.
