I was wondering how a high excursion car subwoofer would compare to a home one? I've built a couple home subs for my house form car subwoofers and they sound pretty good, but ive never built any using an HT driver. I used to have a JL Audio 15w3 in a 5 cubic foot ported box with about 250 watts running to it, and it was very tight and clean, and it made me worry for my windows. m currently using an Infinity perfect 10 with the same amp. Not nearly as much output, but with its excursion and aluminum cone its really accurate and has nice deep extension. My question is would it be worth it to get rid of it and get an HTdriver (Tempest or Shiva). I guess you would have to hear both to make the call, but ive never heard either one of these two drivers for myself.
