Brian, just wondering where you were with this. Did you finalize a design?

I should be starting the build early in the new year. I was going to start it this week, but got distracted by other projects. Basically I'm going to build the first sim that I started this thread with.

Well, I can't wait to see pictures of the saw dust.

Are you going to flare the port exit or keep it straight, as designed?

Keeping it straight. Particle velocity at peak output is going to be so low that flaring it is likely to make no difference.

Some build pics. I opted for a 50 Hz MLTL variant.

I was hoping to have it finished by tomorrow afternoon (in time for a beach party), but the weather said otherwise . Probably not a good idea to bring an MDF enclosure out to the beach when there's a chance of rain anyway.

Sweet ! - it should kick better than a small port BR - it could make a nice Econowave type too

Probably not good for a full-range design. While the driver offset should kill must of the 200 Hz organ-pipe resonance, there's the other one at 300 Hz to deal with. It might be lower than sim'd (the folds may help to tame it), but let's see what the measurements say....

its interesting that pa310, with its 3" coil can reach to 5KHz on axis. In this ancient diy copy of a 1955 K12 (no damping material inside), it sounds like it needs a midrange driver to fill to a K-tube tweeter. A 3-way Boom Unit might be cool.

Hm.
Shouldn`t this ideally be flat or at least kind of flat?
