I plan on running to Fi Qs in a sealed enclosure, using the minimum recommended volume due to space constraints. My power is a Zapco c2k 9.0 4ohm version. I can run the amp bridged or in stereo, so that opens up both the dual 1ohm and dual 2ohm voice coil configs as options. Since I intend to run sealed, I plan on ordering the high QTS option. So here is the dilema: I noticed that the T/S parameters are different for both the D1 and D2 ohm cofigs, and I imagine that the high QTS option further changes the T/S parameters. With that in mind, does anyone have any thoughts on which configuration would behave the best installed in the smallest recommended volume and using the high QTS option?

Need a little guidance. Here are my application parameters: Wakeboard Boat (open air for the most part, so no cabin gain/transfer function) 4 cf to work with Zapco c2k 9.0 amp (2 x 1100w rms) Here are the two options I am considering: 2 x Fi Q 15's in a sealed box, approx 4 cf 2 x Fi BLs 12's in ported box For the 15s I gain cone area but am forced to go sealed. For the 12's I gain a vented enclosure, but lose cone area. It is an open air environment and will be listed to mostly while underway, so there will be a lot of engine and wind noise to overcome. Any thoughts or suggestions?
