Broke leg or not I'm putting my 19s together today. My question is the last owner blocked the bottom from the top of the cabinet. Was this some type of fix? Never heard anything about this one. Thanks
A part of what makes the Nineteen unique among it's peers is it's cabinet design which incorporates a resonant cavity as part of the enclosure. No doubt this in part is what allows the 416 play well across an unusually wide frequency range in the Nineteen, wider than any other Altec system using the 416.
I can't see how eliminating the resonant cavity would do anything to improve the speaker.
