Question Looking for new inexpensive powered sub.

I am looking for a new replacement for my subwoofer as it is the only speaker in my setup that bothers me. I originally bought this 12" Infinity downfiring sub via crutchfield a few years ago. Within a few months it was making distorted nasty unatural sounds. So being fairly good with electronic work, I opened it up and found some burnt out componets inside already. Strange as I didn't have it cranked up past 30 percent power. I got out my tools and soldering iron, and Infinity sent me the replacement parts. That fixed the problem, but every time I turn on my home theater, that sub just gets to bassy or overwhelming to my other speakers. It seems that it may just be too big. I dunno, I hooked a 15" sub to a friends system and I definitley thought it was overkill due to size and output. I am thinking of maybe a 10" subwooofer replacement, as I know an 8" won't produce enough bass response for me. I am unsure rather to go with side firing or downfiring this time. Any suggestions on a powered sub that will give a a nice bass response without being overwhelming to my other speakers. I currently have JBL 3 way mains with an 8" woofer, a nice JBL Center with two 6" speakers and a 1" laminate tweeter. Rears are ultra cheapie JBL 4" single speakers as I can't see the expense back there. What are the difference between downfiring and side firing subs sonically?

The difference largely will depend on the crossover. Down firing subs tend to allow a bit higher frequencies to be output by the subwoofer and soaked up by your floor. Some people like the coupling to the floor the down firing subs provide. I say it will also depend on the type of audio you listen to as well. If you are into explosions as opposed to music, the more coupling the better.

Some people use shakers on their theater seating rather than just rely on the subwoofers to reproduce the physical effects of explosions. In such case a smaller sub is possible where you turn off the shakers for listening to music.

I have to assume the Infinity sub you have is a powered subwoofer and it should have a gain control to reduce the overpowering of your other speakers. If it is not a powered sub and the components that burnt are in the crossover/filter, you might consider getting a subwoofer amplifier so you can control the level of the sub and bypass the Infinity components by wiring direct to the driver. If you don't have a subwoofer output on your amp or receiver, there are active crossovers available. Subwoofer amps built for that purpose have the crossover/filters built in.

In general when you think of size of a sub you need to be thinking of frequency response not sound level. The bigger the sub, the lower the response. Horns and ports and hypermagnets and other tricks can effectivly enlarge the driver, but size matters when it comes to moving a large volume of low frequency air.

If you are dead set on replacing the sub, my favorites are the Carver Sunfire series. http://www.sunfire.com/

Default I just purchased...

JBL Northridge E150P 10" Powered Subwoofer with 150-Watt Digital Amplifier

http://bestpriceaudiovideo.com/

It was $169.00, including shipping.

So far, I'm pleased. But then again, I never owned a subwoofer before. The construction is solid, and the volume is plenty for me.

They have a 250W version as well, but thats more $.

I recently bought a 12" powered sub from best buy. KLH? I guess its their brand or something. It sounds damn good to me. Didnt cost me but around 100 bucks too. Maybe check them out if you do not want to spend much money.
