Good point.

I've checked eBay, you can also get some mid-fi hi-watt (100+ wpc) stereo power amps (Kenwood, etc) for not too much. Not sure how these would compare with the subwoofer "plate amps" you can get at partsexpress.

Be sure to check Audiogon.com as well. Some folks do dump off some decent older stuff on there. I picked up an old 100+ watt Parasound amp with volume controls for just over $100. Looks practically new. Should serve the purpose if I need it.

Andrewbee! That is also a solution, to stick a filter that the car hifi uses to just block anything under say 200 to the midrage and then ad a subamp to the subwofer. I save alot by doing this, noactive or passive crossover, no preamp etc.

For the sealed fostex enlosure do you have any dimensions that may work, also the crossing att 200 is something I havent calculated on I just got it from somwhere maybe its easier to find a sub that works up to 150 instead of 200

Hiya Dave,

Wilma passed ~180 miles to the S.W. and still caused damage and plenty flooding. Flooded 6 homes in my neighbourhood, and nobody had any insurance. After Hurricane Ivan the insurance premiums went up just under 300% so many folks simply cannot afford it anymore. Me I just cut back on stuff from you and I'm okay to pay

Andrew

JohnB,

All you need is a cap and a resistor in // e.g a 220nf with 5k will be -3db@ 144Hz

Sound as decent as that TB W3-594 can sound IMHO. Much better integration/imaging than the Logitech set it started life as .

Cheers,

AJ

Thank for all input, right now it seems like I am going toward a closed cabinet for the Fostex and maybe get away without a filter since the natural roll off. Any ideas on a sub enclosure to match the sealed mid/high?

Sealed. Lot of good 12" drivers out there that would work.

I would still recomend using a capacitor for your fostex. Otherwise any bass content at anything more than background listening levels will push you 168s past thier x-max, thus hurting the midrange and treble as well. As far as something for the bottom end, if your using a seperate amp for that then sealed would be good (or OB, or anything you like), however if you decieded against an active set up then you'll probably end up with a ported prosound driver to keep up in effeciency.

Best place for it is in front of (or inside) your HF power amp.
