Magnets!

[d to the g]

In between trade war tariffs and COVID19, there has been some difficulty in getting magnets.

I want to thank everyone for their patience, but magnets are here. Betsy’s should be shipping At the end of the month.

Best,

Douglas

Mine arrived the other day, thanks.
Break-in recommendations while I sort out the OB?

I like hooking them up to the alternative station and playing at decent volume for a week.

For now I ended up putting 'em in a couple of 1/4 ft3 sealed boxes xo-ed at about 200 Hz. Even with less than ideal alignment the sound is coming along.
I'm working on the OBs, based on the simple half-sheet plywood plans on the website. I will be mitering the edges of the panels to give them a more finished look.
The instructions call out angling the wings to about 45 degrees. Do you expect a sonic penalty from closing the angle to 60 degrees, thereby presenting a visually narrower, less imposing image?
(The lady of the house commented on how attractive the plyboo center panels looked, propped up against the workbench after making the driver holes but I'm afraid some of that enthusiasm may wane when close to a half sheet of bamboo plywood appears either side of the TV.)

They’re on hinges for a good reason! You could even fold them closed when not listening and pop them open for those late night sessions. Also, experiment for what works in your room.

FWIW you can calculate the baffle's directivity control to see at ~what frequency the different angles changes the beginning of baffle step loss: F = 10^6/[wall angle * mouth width].
