Granted the sound wave of the 10"s is shorter than the 15 so it wont quite go as low. So the people 8 blocks away wont hear/feel as much low bass as the people 5 blocks away.

When looking at 15" subs, 2 12's maybe be a better option than the 10's. It will still give you some nice bottom end and will get plenty loud. Best thing to do is let your ears decide what you like.

Guess your cats gonna die.

Sound quality is something else. To get a good sound curve you would need to tune each setup to the car. I do happen to have a bass car I built back in 1995. It's a 1980 Trans-Am T-Top car with 14 10" subs where the back seat use to be. Oh, I use to co-own a Mobile Electronics store. We did manage to build a couple of award winning cars as well as made it on a magazine cover. Didn't mean to high jack your thread, just started rambling.

Ummm no.... Basically everything you just wrote is wrong.

10" is the diameter, not the surface area. Average 10 might have the surface area of 300-400 cm^3 whereas a 15 is around 700-800.

The resonant frequency does play a part in how low the sub will go but its entirely up to the DESIGN of the sub, not the size of it. Size determines surface area and cost, thats it.

Displacement determines volume below 50 Hz and above that its more-so sensitivity.
