thats what i ended up buying.
800 watt rms, 2k peak
28-1.8k hz
damn good for a 10" woofer and it was only 119+30 shipping
i was gonna go with a single 12, but... the 10 is lighter, the box will be smaller and lighter, its gonna be getting at least 1k rms watts and its going inside the cab of my del sol behind the seat. so it should be pretty damn loud on its own.
as far as ported vs sealed
sealed-
Advantages
Easy to build, smaller enclosure size, lean tight sounding bass, better power handling vs. ported design and Linear low bass extension.
Disadvantage
Less efficient as compared to ported design.
ported-
Advantages
More output at the tuning frequency as compared to the same woofer in a sealed enclosure, higher efficiency.
Disadvantage
Larger enclosure size, Calculating enclosure and port dimensions more difficult,easy to blow woofer if power handling limit is exceeded.
thats straight from soundstreams website, and i figure since they are the most highly awarded speaker maker since 1983 i think they would know
