Recommend a driver for salvaged powered enclosure... Or...?

Hi All,

I am considering a quasi-DIY project here -- apologies if this is not the right place to post this but it seems to be the best fit.

I have been given a Cambridge Soundworks Powered Sub Woofer II with a blown driver. It looks like the plate amp is ok but the surround on the 8" driver went bad and is reading infinite impedance across the coil. Given that surround is completely shot on the driver and I am guessing it bit the dust by being driven in this damaged state.

What I am pondering: is it worth getting a replacement driver for this? I thought if there is an inexpensive (<$25 up to maybe 50 or so depending on results) drop-in driver it might be be a nice enhancement to a computer / gaming or maybe tv setup.

There is very little info on the original box and I have been unable to track down specs but unlike its respected predecessor, the PSW I, the PSW II was, it appears, a bit of a miss. Here is the owner's manual download (it does not contain much info on the components): http://download.cambridgesoundworks.com/manuals/psub2.pdf

Although nothing special, the sealed enclosure itself is solidly built with an internal brace. The internal measurements are ~7.5"x19.5"x9.75". The plate amp is labeled as 400 watts, accepts L & R speaker level input or L & R line level input via RCA jacks. The low-pass filter can be set to 55, 80, 100 or 140 Hz and there is a bass level gain control. Inside it has single L & R output leads that connect to the speaker. Its components look of decent quality and has a pretty hefty transformer, a couple of beefy capacitors, etc.

So does this notion have merit or am I off my rocker? I see places like parts-express.com have items that might work but I figured I would run it by you folks -- what with your notable sub-savvy. Another possibility would be to perhaps salvage the amp and use for...? So what will it be? Cheesy Sub? Boat Anchor? Any thoughts are appreciated --

Thanks for your attention,

The cutout looks to be a pretty standard 8" mount so my thinking was to go for something in that size.

Regarding impedance: I just double-checked and the only info on the driver is "Cambridge Soundworks" embossed on the back and a date: Sep -5 1995.

Also, faintly on the back of the cone it looks like:
P680100
95 030

The lower numbers might be a year - week indicator but there is nothing obvious (to me) suggesting the impedance, but perhaps someone might recognize something?

Thanks for your response!

Thank you for the info! I was not sure about the flexibility of that type of dual 4 ohm driver but suspected that what you said about wiring for 4 or 8 ohm might be the case -- thanks for clearing that up! In addition, I had not seen the items you mention -- I will definitely take them into consideration.

Decisions decisions...

Thanks for your response!

Regarding contacting Cambridge: I had checked with them earlier and they were not able to help but given I have a bit more info now it does seem like it is worth another try.

Also, thanks for your noting the issue regarding the size of the driver -- it had not occurred to me that there might be such variations.

Thanks again!
