All things considered, I would strongly advise you go for this $1200 option. OR ask Tyler what the quid pro quo is & purchase your own separate amp with electronic xover facility to drive 4x15".
Don;t worry too much about the "pro". And your room is large, very difficult to get coherent energy in so large a space. AND many women respond VERY positively to rhythm (which means midbass energy), so maybe a good thing?:)
I also have to keep the system clean
Whadya mean??
