Guess you've never leak tested any early Altec or similar consumer cabs.......... How do you think I learned this?Indeed, if you look at early T/S programs, considerable leakage [low Ql value] is recommended in the vented alignment design routine due to how hard it is to seal one up properly for most efficient vent action.
Heathkit's vented cabs OTOH taught me what 'tight' was all about. Ditto theirs and AR's sealed cabs.

But with the days getting longer(daylight) this should improve.
Barring physical impairment, I don't think I'll ever stop building and repairing things. The Good Lord put a few "fixers" on the Planet to take care of the needs of the less skilled and I happen to be one. I like my role.
