Post Subject: "Random Venting"Posted by Paul S on: 10/17/2024
Romy, I am reminded of large olden days enclosures that were "randomly vented", in that the venting was meant to diffuse backwave reinforcement/cancellation rather than trying to use the backwave to augment the front wave. It is very difficult these days to search for Tesla (Tesla a.s., CZ) speakers, since all search engines are trained to show Tesla cars. Anyway, the large Tesla ARO woofers were used in large and heavy double-walled enclosures with "diffusion vents". I experimented with this concept by drilling multiple random sized holes in the backs of empty boxes, and at times I used a rock wool "curtain" behind the driver. These enclosues do not "help" the driver in any way, really, but they come close to IB in terms of allowing one to hear what the driver itself has to offer. I did not try any of these enclosures "corner loaded", and - of course - the room figures largely in that case. Not to say it wouldn't "work", rather any particular "solution" might be fairly room specific.

I think the "big problem" for any large woofer candidate is equalizing output in the passband, and most fancy "solutions" have the real world aim of getting LF from a "reasonably sized" enclosure. I think, regardless, there is no Free Lunch with LF, although I certainly agree there is a lot of room for the improvement of Musical Bass. It always gets my attention when someone goes after Musical Bass.
