I decided to try my hand at routing, and leather work. I just wanted to use the router inside, but the 18mm board was 17.02 and the 18mm quarter round was 19mm. So I had to do the corners myself anyway. So my skills were quite stretched out here..
Even a bit of balsa wood in there, and I've not used that before either. So I'm happy enough. Just a cheap wrap as I'm not sure even oak would of taken to the r18 corners. Quite a bit more rubber crumb underlay went in, and various stuffing types weighed out.
Sound good, but I can still hear the box playing a part.

Need to add a cap to the top but posting these early. Ported Alpair 10 tower, built for a local buyer. Still playing with the tuning a little but early impressions are positive.
Wood is Baltic birch plywood, edges are solid maple. Base is MDF painted black with some light speckled texture from a stone style paint. Finished with polyurethane.

Slick! Kind of reminds me of the super rare '50s era

With that dimensions you could consider a decent back horn loaded bass, or a modified Onken-360. If midrange suffers, a front horn would balance things...
Also, have you guys tried Dammar varnish on the cones of fulrange drivers?
(do not varnish the surrounds
)Cheers,

My latest project uses dual Tang Band drivers in back to back transmission lines. The woods are walnut and wavy oak. The drivers are epoxied back to back and floated on the baffle with caulk. They sound great, very realistic, bass down to about 50Hz. The top end is a bit soft but I can’t hear that high anymore.
