I presume you're soliciting everybody. My bench is pretty quiet as I get ready to move. One lucky guy purchased the field coil prototypes. I miss them terribly! My OBs are currently loaded with a pair of BetsyK's that had the old hemp matrix cone. I really think the new black cones are an improvement, but having a bunch of used speakers around doesn't further my purpose of selling them!

I've really been enjoying this First Watt DIY stuff. I've got the parts for a B1 of my own on their way. Not sure when I'll get it assembled, though.

Hi,

Here is a recent project for Betsy-K (MLTL, 40Hz) designed by GM, I do not remember the link but I had copy/pasted everything in a document.

Rgds,

Just ordered a pair of betsy's. This will be my first try with FR speakers. I'm going to make the project betsy first. Amp will be Magnavox console convert el84 pp at 10 amps. Should sound good!

congrats opa1.

I had an old console, pair of 6bq5 (same as el84 I think) outputs per channel.
It made James Taylor sound so wonderful, even on non full ranges.

Open Baffle design ?
