Woofing "Q"

Todays query pertains to sub matching to a stand mounted two or three way speaker. Irrespective of room acoustics and crossover over or underlaping points and levels. What are the effects of mis matching Q or damping. Is it detremental to match a acoustic suspension sub with a ported monitor or must they both have the same box alignment. This assuming that a sealed box is quicker than than a bass reflex box. I curently am using sealed Yamaha 10m monitors with a Yamaha sub that has two 8 in drivers and a port. It is matched pretty well. The Cary 805c is telling me I need to step up my game, but I don't want to lose my alignment match. Halp before I make a 'greener grass' mistake.

Can you adjust the damping of a box,either sub or sat, acousticaly, by putting a 'brick' in the box or a 'sock' on the port? Thanks all for your patient answers

I understand that level and xover point are adjustable and must be optiomised first but adjustable dampining Now that's a new concept . Marty: is it more noticible to have an over damped sub (lower number) compaired to the monitor or the other way around.

I remember a white paper from Dunleavy on multi way speakers and his statement said that the only drivers that should be ported ( hi q) are the biggest ones. Does it make sense that you wouldn't want ported monitor and a sealed sub? idk Or does that only apply to mono amping?

Also I am using a SET amp so doesn't that raise speaker Q because of its hi output impedance. Of the speakers that are going to replace the Yamaha 10m (which are sealed) most of them tout " impressive bass for a speaker this size". Isn't that just another way of saying "kinda loose" Is that something that I want? My room is kinda small and a loose sub seems like it could get out of control real fast.
