Doing great!
I finally cleaned up the basement after it flooded a year and a half ago. I also lugged the EV Sentry IVs downstairs and discovered many terrible sound transmission issues upstairs emanating through the floor and heating ducts. It's funny that the Altecs upstairs don't do the same when I am in the basement. Both upstairs and downstairs layouts are identical.
Worst offender was the adjustable heat registers rattling in the duct work and also the dampeners in the registers. Fixed that by slipping automotive car door edge molding onto the registers and removing the dampeners. Doesn't sound like someone hitting the duct with a drum stick anymore, but still tons of sound coming through. I still need to somehow wrap the 6" ductwork running across the basement ceiling with something sound deadening. Too bad they outlawed asbestos.
I also need to remove the drop ceiling, stuff the floor joists with 12" of friction fit fiber glass in the 10" joist space, and I was thinking of covering the ceiling/bottom of the joists with removable 4x8 sandwiches consisting of from bottom to top; 1/4" oak ply-wood glued to 1/2" or 5/8” gypsum board, glued to 1/2" foam carpet pad and screwed to the floor joists with rubber sleeved and under headed screws so I can remove the panels and access the floor system. I need to come up with some kind of channel to wrap the sandwich edges with like they make from 1/2” and 5/8” drywall.
Also need to glue something on the upstairs stairwell hollow core door as that is also a bad sound source as well a dampen the stove range hood and lots of other things upstairs that rattle.
I’m making my kids buy me a bunch of black light posters for fathers day and birthdays.
And… finally got my Crown DC300A power amp fixed, now just need to do the same with the Stax SRA12S preamp, and re-cone the 416-8As and I can listen to my A7-500s again after 15 years or so.
