I don´t understand very much the need for a low resonance frequency.

Low Mms and Low resonance means High Vas.

A 10" driver with low Fs and the desired sensitivity (including BSC) would have too low Qt to work properly in a BR, and for a BLH of the given size the low Fs is unnecessary.

High Vas is ok
the Voume of the box can be near 200 Liter

the most importent fakt is that he sounds good in the midel Frequenz Range so the cut of can be near 2,5 Khz
