First I apologize if this is wrong forum.

thinking about either Yamaha, or Sony, any suggestions?

thanks in advance.

hi gychang
any comercial subwoofer under $100 is frienkly not worth anything
most of those comercial 6" subwoofers have poorer bass than any well done good 2 way system and sound like fried dog poop
you will be much better off making a subwoofer
this is diy forum if you did not notice
any $100 comercial sub will most likely have $10 woofer in it at best
if you buy woofer for let say $50-$80, you can built quite decent subwoofer, much better sound quility than $100 comercial sub
good luck

Sony Xplod 12" 5 sided poly car subwoofer works good. Clean sound with little distortion.

There is also a 10" version of the same woofer.

Costs just under $70 at Wal-Mart for the 12".

350W RMS, 1200W Max Rubber Surround, and the lead wires run under the spider.

I replaced my old blown 12" with the new Sony Xplod, and it sounded like I went to a much larger speaker, with the same 1.25 cu ft enclosure as my old speaker.

Also, my amp that pushes over 300W RMS does not push the woofer to the limit, even with the deepest bass notes while starting to clip. :eek:

The bass is solid, clear, and the low notes sound powerful and controlled. Even at low volumes, you can feel the bass.

Doing that kind of abuse to my old 12" woofer didn't let it last more than 15 mins before it blew LOL! :hot: The Sony however is a brute and takes everything I throw at it, and you can hear the music in the street!

Hi EWorkshop1708

that's a good idea, car woofer
I did not want to suggest car woofer, because gychang wanted home theatre subwoofer, but if you are on the budget, that will work fine
obviously you can select hundreds of woofers in that price range
parts express has lots to offer, many on sale

interestingly, that sony Xplod woofer...I have similar experience
I have once made a system for my friend for his lab, we share the company, but he is in differrent department, so I made a two satelite system with subwoofer, whatever speakers I had around, dont remember brand of woofer, powered by 2x60watt amp for satelites and plate amp for sub....he blew the woofer in about a week...he listens way too loud when he stays late at work
than I replaced the woofers with Xplod, picked it up on sale in BestBuy, I think $19, that think is undestractable!!

I will post a picture, dont remember weather it was 10" or 12"...

Guys If you havent noticed, the car sub market is now a world of its own, typical examples with very large rubber surrounds and heavy cones, will go deeper than any hi fi style can and are perfect for Sub bass at home.

IMO a car sub, in the right box, makes a great HT speaker. As long as your subwoofer amp can drive a 4 ohm load or less, it's all good.

For HT, you want the frequencies under 40Hz to be nice and strong. Good Car subs have no problem doing this.

It's really nice to have a 20hz note shaking the room, while watching a movie! Also, for really bassy music at home, a car sub is awesome!

Before I got my Sony Xplod 12", I checked out the speakers on Parts Express. Lots of nice speakers, but the cheaper ones IMO were not what I was looking for. I wanted strong low frequency performance.

Also, I've broken the lead wires on subwoofers before from high excursion, and I wanted a subwoofer that had the wires run under the spider so they would not break!

I'm also planning on using a 10" Sony Xplod car sub for a small computer sound system. Car subs are cheap, and have lots of bass, and do good in smaller enclosures.

8" Dayton DVC subwoofer (SD-215, I think is the model number). Good for sealed or ported. Just use WinISD or something similar to calc out a box you can live with and use it with the 75 watt Dayton sub amp or whatever else you can find handy (think Apex Jr. has a decent cheap plate amp).

I know you're wanting to run this with one of your sets of BiBs you recently built. Maybe just run a line from each channel of your JVC amp to one of the coils on the Dayton with an inductor inline to low pass it . . . give you around 4 ohm load on the amp which should be just fine as I used my older crappier JVC Hybrid Feedback to run 4 ohm car speaks for a good long time with no ill effects.

Let us know what you come up with. Loved your woodwork on the BiBs.
