Thank you Brent
Home Theater (HT): Front -- Tower II SEs with megawoofer upgrade, Center -- QSO626s (horizontal centers at sides of Display due to cpnstraints) upgraded midbass drivers, Surrounds -- older dipole surrounds. Tallboy sub to be rejuvenated for addition to HT.
Two sets of LCRs: too big for living room HT (WF'tor constraint?!) sitting idle at the moment
2-channel system: FF1s
Dedicated sub in master bedroom integrated with soundbars...
Unfortunately the family really doesn't appreciate being able to 'move air' for true HT effect -- like the cannon shots in Master&Commander!

. ...so expansion is problematic.
Aside: in upstate NY and a few years back a Craigslist by a Vermonter literally giving away a New Larger Sub... I didn't know how to explain myself if I were to have brought it home! Arghhh...
