Awesome thread. Knee deep in the project as we speak, excited to talk about sonic differences. Fully taken apart, cutting up braces and about to glue them all in and dampen the interior of the cabinet.
I'm new to modding Klipsch speakers, but wondering if anyone has experience with damping of stiffening up the horns. Tyson and Danny threw a piece of NoRez on there, but would it be better to Dynamat the rear to kill reflections, add mass, and possibly stiffen things up a bit? Would this cause undesirable sonic changes that I'm not thinking of? There are pics in earlier posts where other Klipsch modders did do this to other speakers (clay, bitumen, dynamat, etc), but just curious as to what the rest of you experienced modders would do.
I suppose this would go for the stamped steel baskets of the woofer and passive radiator too. Would it be better to Dynamat these to kill reflections and mass load the driver a small amount?
