How about an LSi subwoofer?

Yeah!
Sealed box...or maybe passive radiator...big amp...big driver...response down to about 15Hz...all for $600!:D

how about less than $1000?:rolleyes:

you might be able to make your own sub. that is what i have planed for this winter.i made one the car a few years back and it was quite easy.

Are you talking about the subs in/on Parts Express? Or taking the dimensions from like a Velodyne and going from there.
I built a center from Parts Express and used Polk drivers, SL2500 tweeter, and a crossover from a CS400 to try and make a better match for my monitors. I turned out as planed but a CS350ls seems to match better.

Everyone thinks I'm ****. I have twin jbl 2226 15" loaded in theatre cabinets runnin' here. They get power from a Crest Audio FA901 amp which gives me about 550 watts of overdone subs! What the heck, I had 'em, might as well use 'em!:eek:

i would really like to build something to the like of a sunfire sub.
but were can you find a real good passive sub,and a nice big plate amp for not alot of money?

I don't know about the "not a lot of money" part, but Bryston makes a modular amp called the PowerPac. It comes in 60, 120, and 250W flavors. Their amps are renounced for their bass abilities. My guess is that 250W baby would make an incredible sub amp.

I built a passive sub for my father-in-law a while back. I used an 8 ohm JBL 12" car sub. His receiver (Technics) has a built-in sub amp with a variable crossover, though I doubt that it has much real muscle. I used the equations out of Radio Shack's "Advanced Speaker Systems" book, and built a sealed box. It's theoretical -3db point is 28Hz, but since it's a sealed box, it seems to have decent output down to the 20Hz range. I only had about $95 in it.

I've got a plate amp out of an AR S12HO powered sub. It's not entirely healthy--- has a hummm. Not really that great of an amp to begin with, but probably fixable if anyone wants to try and use it. I believe it's supposed to be something like 140 Watt @4Ohm, and has a 40-160Hz variable crossover, speaker and line in/outs.

Oh, and I've got the 12" Driver from that sub also. I sold the enclosure to someone else, after having probs with the amp.

If you keep tabs of Velodyne on eBay there are amps and parts which come up every now and then. The HGS and SPL series have the class ‘D’ amps which are rated some where around 3000 watts peak. That is why I asked if you were going to build one matching a Velodyne. Parts Express has some good sub kits. There is one, at least, which hits 20HZ. It is at least worth a look plus they sell amps sepratly, don't know their wattage thou. I did research on subs when building my new H/T room, you should get one which hits below 20Hz. I did a comparison for a friend with his sub which went to 36Hz with an explosion in Die Hard there was hardly any bass noise. It showed him how much a good sub adds to a system.

i would get the wood my self and build it from the ground up getting a kit from one of those parts houses makes it no fun
getting the absulute best sound quality is not the most importent thing to me.just want to add a little more bottem end.

I know that MCM sells a pannel amp that does 250 watts with a variable 40hz to 160hz crossover, auto power on, and fully variable phaze control for $129.00 or so. They also have quite a lot of drivers from modest to pro-audio quality. Might be worth a look:

No, I don't work for 'em, but I have ordered some stuff and I like their company. A repair tech I know turned me on to them.
