    Installer was here today to diagnose. I need listen and explore more thoroughly but he's declared success. He revised the Triad amps settings substantially. He confirmed they were set for 8 Ohm, so in the circuit they were operating as 4 Ohm subs (and not set as 4 Ohms and drawing at 2 Ohms each). At a quick listen, the sound is full and the walls aren't rattling under more than reasonable volumes.

    There's maybe a little adjusting for the Silver sub's mount. And a wall sconce to be tighter, maybe given a rubber gasket, to reduce its vibrations.

    I'm cautiously optimistic, but I'm hopeful and look forward to listening and demo-ing the next week to confirm.

    The one downside so far is the Silver On-Wall is set at 20Hz with the 48 slope, so there's no content below 20Hz. With an in-room sub in my living room ported for 16 hz, I'm used to have some very deep content. But if the system is otherwise working well, I can augment with a smaller in-room sub dedicated to sub-20Hz content as a future upgrade.

    I ran Audyssey on my pre-pro (after setting my front speakers back to Small and base to just LFE) and it seemed to work well. I had to make some adjustments to Input Gain on the Triad Amps but they weren't as drastic as when I had the amps set for LFE passthrough. So I think the system is working better.

    It appears that the subs were being given too much deep bass and were being over-driven, causing them to clip and shake the walls.

    Makes sense.

    I had a similar situation a few years ago when I was contacted by a Triad customer who's installer really made a mess of things. The Rack Amp settings were way too aggressive and the inwall frame screws weren't tightened enough. Once those things were properly addressed everything sounded great.
