Can someone run a frequency response graph for 4 12" 2006 dual 4 ohm L7s in a 13.2 cubic foot box tuned to 34 and 37hz please? My T/S parameters are conflicting in bass box pro 6, so I've designed my box with the 2004 L7s and their response may be different than the 2006 L7s. Thank you very very much, I appreciate it.
