Heather can you recap what has been modded to date ( I've now lost track ).
F.I. , did you ever add a tweeter on top ?
Basic Updates.
Modified Woofer replaced stock woofer (Same model)
Tweeter with back-cap pad and vent holes replaced original (Same Model)
Horns modified with 2 layer of QPad lead based damping material.
Notched Fiberglass panel installed between woofer and horn.
approx 4 cups of well fluffed lambs wool in lower cabinet area around woofer.
Existing Rock wool left undisturbed on sides and back.
Removed rock wool blocking "vents" at ends of horns.
2 tiles installed to the bottom of the cabinet - one 18x18 ceramic, one 12x12 granite with RTV silicon for constraint layers
2 tiles installed to the rear panel of the cabinet - one 18x18 ceramic, one 12x12 granite with RTV silicon for constraint layers.
Replaced internal wiring with 13 AWG stranded silver wire in teflon jacket.
Major rebuild/update to crossover network with polycarbonate & Teflon caps
Used stock inductors & tweeter controls.
Installed rebuilt Altec Bass Energizers with (new) Bennic Electrolytic caps.
After listening, removed Altec Bass Energizers (Maybe later) ...
I have NOT installed the stone tops with constraint layer
yet but I still plan to
(time and $$ - I want to find a DEAL on price, and not pay market cost)
I have not added a top tweeter yet. I do have a schematic for adding a JBL slot tweeter,
but I'd build the crossover and see how that works.
