Not replacing, just adding and no, they don't really fit lol.... But that's never stopped me before!
I was just messing around with their placement in the back of my room this morning. I won't be able to have them directly behindy sofa but on an angle, they will work (only because my equipment cab is directly behind the seating) but be a bit tight to get to my rack.
It's only me in there 95% of the time, so it's all good.
I'm in the process of figuring out how to EQ everything... Man, I with there was just a box with hpf/lpf knobs and that's it. That's really what I need.
Hoping to get the Monolith HTP-1 once the bass modules comes out, the ability to run 3 independent subs with full eq etc in the unit will be awesome. I will be powering them with a fp14000 clone.
