the reason i need these measurements is for an enclosure basically. my problem is that im in a van, the seats are taken from the back. in the very back is my sub enclosure and behind that is where the rear speakers are. this is a problem because the sub really screws up the sound from the back speakers! so im going to build a satellite-type enclosure for the kappa perfect 6.1's (they will look like small home speakers.) i know these are meant for a door, but i dont have many other ideas, and this doesnt seem like such a bad one. any other suggestions would be appreciated.
