I will take a look anon at
@eddantes link. We're kind of busy getting ready for houseguests coming this weekend for -- that big Amurrican holiday that happens next week. The one where we all eat ourselves into a stupor, then euthanize any remaining functional brain cells by watching the amusingly misnomered pastime called
football.
Oh, on topic (?!!!???!) I think the biggest downside to good ol' monkey coffin design are the built-in resonances. Not a deal-breaker, but one of those things that has to be designed around or mitigated after the fact. On the other hand, boxes are easy to build.
OK, in
theory they're easy to build. Unfortunately, for some of us,
competence is a stretch goal.
Yes, I really, truly built this (these... yes there were two of 'em). No, I am not proud. It was a quick & dirty
experiment with some cheap fullrange buyout drivers from PartsExpress!
Going forward, I think I'd build 'experimental' boxes out of gypsum board ("drywall").
