I live in an apartment so i dont want to shake the place down but i want try to get down to 20hz.
The room is half kitchen half living room. total room is 15' 4" x 22 but the theater portion is 15'4" x 13
the other thing is i dont have a workshop w/ woodworking tools to build a box.
I'm looking at trying to find an old sub on craigslist that i can reuse the box.
I've read a bit about the SVS SB12-Plus (or the NSD is all i see now) and i'm tempted to just buy that... but building is so satisfying
Supposing I can get a hold of a box what would be a good woofer / amp combo for my situation?
Is recycling a box a good idea?
What do i need to consider as far a the structure for the box for good sound / resonance or whatever?
You like that 'resonance' bit there? i'm trying to act like i know what i'm doing / talking about... lol
thanks in advance

erich has flat pack enclosures. diysoundgroup.com. he is a member here and does it for a hobby, not for a profit.

a driver and an enclosure work as a team. you can't just plop any driver in any enclosure and expect it to work.

an inuke nu1000dsp will be enough power for an apartment and it has on board eq.

i wouldn't worry about trying to get down to 20hz with authority in an apartment because the sound is going to go right through the walls and buzz everybody in the complex.

Listen. It's All Good.

If you're okay with a bit of work, these flat packs are great

http://www.diysoundgroup.com/flat-packs-1/subwoofer-flatpacks.html

Glue them together, then sand, and paint/veneer. If that is still to much, then these Dayton cabinets might be better.

You would simply us a jig saw to cut out the woofer and amp cut outs. if you completely botch one of the baffles, you just order a new one

http://www.parts-express.com/pe/showdetl.cfm?Partnumber=302-862

Use the following woofer/amp combo in either the 3ft3 or 3.5ft3 box and you're golden

thanks fellas!

I like the DIY 1.25cu ft... small footprint in my small space.
I can screw and glue ( i do it to my girlfriend on a regular basis!! lol)

What would be a good 10" woofer (is that the driver?) and amp combo?

The TC Epic 10, with the same 500 watt amp I linked earlier. The TC woofer is .07" smaller then the cutout Eric has for the 1.25 ft3 box, so it will fit just fine.

Good for you! not too sure about the glue part, that's unfortunate biggrin.gif

Use PL PREMIUM for any "gluing" of boxes, works great, expands into gaps and bonds rediculously well.

I did the TRIO12 in a huge box earlier this year, and now have a SDX10 kit that I just received. I am doing it to spec this time, and also have the 2 passive radiators. This option lets you change the tuning of the sub without disassembling it (external access to weighted discs). You may find some tips on my build thread to help you. That was my first one too: [ TRIO12 build ]

I recently finished the sdx 10 from css and its a pretty decent performer. Only change i made was the actual dimensions,the volume remained the same. Only thing i did not like about it was i built the box while waiting for the sub to arrive and found the sub to have a very thick surround which would not allow flush mounting. If i were to do it again i would put a second layer of mdf on the inside . Aside from that it sounds really good musically and adds a real pounding when watching movies. You can surely piss of your neighbors with this biggrin.gif

Oh and you can see my finished sub in the diy gallery if interested.

on my TRIO12, I added another layer on the outside of the front baffle and rounded over the corner of the outer circle. I like the look, but couldnt imagine doing all the way around on that beast.

Socketman, was it the sub's actual surround (which is quite big) or the rubber ring that's installed? I've removed the rubber gasket before, and flush mounted the driver's frame. Then only the actual surround protrudes from the baffle. Still not flush-looking, but it looks better this way to me.

here is a close up with the hard rubber 'surround' AND weatherstrip installed to prevent airleaks.

caper_1 , your Trio12 box looks fantastic! i like the DuraTex
my box came out looking pretty rough. i did kinda of a fast and loose job.
it'll work but to make it look ok i'm going to have to do some more work
