I am using a PearlAcoustics Sibelius, and am very happy with it. Don't know about driver, but cabinet is 1.5" solid oak. Love those speakers, not even thinking about changing them.
Voigt Pipe speakers still a thing?
Are any of you currently using/building Voigt pipe speakers? If so I’d be interested in the drivers and materials you have used with success. I recently stumbled on to Real World Audio on YouTube and Janos there has me thinking of building a pair this year.
