Need help with DIY open baffle speakers using console drivers

[Isaac C.]

Hello everyone, I plan on making some DIY open baffle speakers using some drivers I pulled from a GE stereo console. My biggest question is what is a desirable baffle width and height to have for the 12" CTS 933C675-4 drivers? My other question is mid-range and tweeter placement? Please see the attached picture for the drivers I'll be using.

This simple open baffle was part of a Homebrewer article I wrote for Sound Practices back in the 90s. It was designed by G. A. Briggs of Wharfedale which was marketed in the 50s as the SFB3. It doesn't follow current audio conventions but it adheres to the laws of physics.

As a cheap and quick experiment, you can probably extend your current baffle (with drivers) dimensions to match the G. A. Briggs design.

Hope this helps!

Thank you! I will definitely take a look!

Experiment with cheap 1" thick foam board or even thick cardboard when figuring out layout and what sounds best. I have 15" woofers and midrange/ tweeter horns from an old tube console I've played with OB. Using heavy corrugated cardboard I found 24" wide by 36" tall sounded best with a 24"x24" base coming off the back with short 1/2"" tall puck feet at the front tilting the whole mess back a bit. I still haven't gotten around to making something more permanent out of plywood.
