Can a decent sub be made from an Alpine sub speaker?
I recently inherited a 12" Alpine Type R car subwoofer speaker from a friend (without the box enclosure). Seeing as how I have no desire to install it into my car (I find car subs to be obnoxious), can I make a decent sub out of it? Also, is there a service that will make a sub for me if I send them the Alpine sub? Just as background, I'm already running a Velodyne CHT-8 and the Alpine sub would be my second.
keep car out of the home!
remember that the alpine subs, while great for a car-sized space are really not designed to go into a home environment. Many are 4 ohms are less nominal impedance, making them all but impossible to run off of most HT receivers. Couple that with the fact that you'll need to find a separate amp you can power this sub with, find/build a proper box, and have to deal with the frequency cancellations of having two subs in the same room...you're probably better off spending your money on either another velodyne or an upgraded sub. sorry to p*** on your parade...i simply want to save you some heartache and $$ ;)
You can make home subs with car drivers
I recently purchased this 15" 37Hz. Fs car driver that sounded okay in my very large living room:

The output below 50Hz. was weak (as the 37Hz. FS spec suggests) but some EQ solved that problem. The +/-20mm XMAX prevented overexcursion damage. But the combination of the low impedance voice coils (4 ohms) and EQ boost made my 150 wpc stereo amplifier quite hot when using this car sub in my living room (150 watts for each voice coil).
