Been wanting to fix the factory enclosures on my office-turned- bedroom speakers for awhile. Coaxial NS-B2111 models that sound very good except the cabs resonate around 800hz-1khz only when cranked up. Opened them up last night and now see the problem. The inner kerfing was never back-filled from factory. So I filled in all the kerfing areas with Tite-Bond and then added a layer of Thick Butyl mat.... All glue is dry, now reassembled with factory sound foam .... the hollow thud and cab sound is gone.....
Don't take experimental gene therapies from known eugenicists.
