Use a car woofer for home audio cabinet.. any downside?

QUESTION—I need a replacement 12” woofer for a large volume enclosure. A REL Britannia B1

I know the T/S parameters of the old driver which is helpful. I have been shopping and see a huge range of prices from $40-$1000. Seems like a suitable replacement is $400+ if I were to go with a home audio driver.

What I was wondering is what about CAR stereo woofers? I see a ton of 12” car stereo woofers that are extremely well built (sometimes better than home audio), have good parameters, and are at a lower price. The only downside is that they are DUAL VOICE COILS, DVC. I know a DVC would have to be wired in series thus taking 2 ohm to 4ohm for example. Is there any downside to a car audio woofer? Any downside to merely connecting the 2 voice coils?

 

Thanks for your thoughts!

MATT-- I tried REL  /Sumiko about 18 months, and got nowhere. They claimed no parts and no support. Maybe different for your B2.? But I will try again. You are correct these are unique subs! Hard to replace. Their new stuff is nowhere even close to the performance.

TIMLUB-- That looks almost like the REL driver. The pics on ebay kind of suck, but I will contact the seller. Tonegen made them for NHT, did Madisound make their own and just give it the same number?

ERIK--I actually posted this thread because I too found that BK electronics in the U.K. Problem is they have never written me back.  Emailed many times, called and left messages. Looks like they don't want to do business in the USA. At checkout says UK shipping only. Bummer!

Hi Steve,
    The 2 on ebay are a bit high.... Yes, Madisound had this knocked off for them. I believe Foster made it.  Neither of these is the Madisound part.  I don't recognize the part with the fins on the magnet,  but the other looks to be the original Tonegen/NHT.
