Dead DefTech ProCinema 600 Subwoofer - Any Replacement Amps Available?

[Strong Eagle]

My DefTech sub has died, leaving me with a white box. The amplifier is dead, otherwise the sub is in great shape. I'm not too sad, though... I bought a new SVS SB-1000 Pro. What a difference.

DefTech no longer carries the amp board for this sub and I've seen a handful of used amp boards for fairly outrageous prices.

Given that this sub optimistically only makes about 35 Hz, I wouldn't want to spend a lot of money making it whole again, but then again, I am also a very good handyman and I like to repair and restore whenever possible, even if I'm going to give it away.

So... are there other plate amps (or otherwise adaptable) available that I can stick into this box, even if I have to do some custom work?

TIA

You can maybe check out plate amps at parts-express.com. May not find one with same dimensions or dsp, tho. I really wouldn't bother with most DefTec subs, tho. Maybe frankenstein one with an external amp for your garage or something....

"I really wouldn't bother with most DefTec subs" Ya... I'm beginning to see that. Popped over to eBay... could buy a used plate amp for $179, can buy the whole used sub for $99.

Hmmm... what can I make with a nice looking white box? A guinea pig hutch? A secret stash for valuables and that bag of weed?

Repair vs a new "good" sub is a no brainer, purchase a new sub with warranty and much better performance.

Yes, I am now the proud owner of a shiny new SVS SB-1000 Pro... great for my room. I just hate tossing stuff unless there is no way it can be fixed... and in this case, it looks to be cost prohibitive to do anything.

There is never any point in spending any money fixing junk. That unit was junk when you bought it, it is junk now and will be junk if you fix it.

I wouldn't bother with that 8" sub with it's limited passive radiator at all....it's just small more than effective. Sub pretender.

Comes down to what you could do with it if you got it working again. It will have no value on the marketplace. You would be lucky to recoup the cost of the plate amp. If it only goes down to 35Hz then it might be useful in a garage or den setup for music. Parts-express is about your only option but their amps will not be tuned to your particular speaker. Cheaper subs are usually destined for the bin when they break down.

Your characterization of this DefTech product as "junk" is not accurate.
