Car Subs as Cabs? Anyone try this?

[anonymous1015111]

I have been reading through specs for Car Subwoofers (for my car of course!) but it go me thinking...Could these be used for Bass Cabs? If the specs are right (8ohm, 300watt power handling) they could be mounted in a typical car sub enclosure (which can be had for cheap), add in a Low pass filter and Bam! Cheap powerful bass cab.
Discuss.

This comes up about one a week. Car subs are just that: car subs. They are worse than useless for a bass cabinet.

No, it would not work well at all. The average car sub is nowhere even close to efficient enough for pro audio usage. On top of that, the inductance found in your average car sub is WAY too high. They break up and start sounding god awful much above 200Hz. There are a few exceptions on the market, but even those suffer from efficiency in the mid 80db range. Just not a viable option I'm afraid. My .02 on the subject of course.

Plus they only work in cars. That is an important bit, the enclosure is the car.

Ahh, saw the sensitivity ratings (85-90 typical for car sub, 97+ for Bass Speakers), didn't think of that.
