1 15 to 18", It's a sub.
2 single driver, keeping it simple.
3 floor firing, a little safer.
4 SPL, but I really gotta have both.
5 conventional, yes small is nice, pocket size even better, but no big deal.
6 under the center channel.
7 built in amp, you can do a better match.
8 manual parametric, first, but auto might be a nice addition.
9 $1200-$1700, low loud and tight.
10 just plain black, nicely trimmed.
thanks
