Beyma 12XA30Nd Speaker

These are the most expensive speakers I have made. Drivers are Beyma 12” with a titanium\polyester concentric 2” dome – 12XA30Nd. Efficiency is 98db\1W\1M for the woofer section and 105db for the tweeter. The drivers can handle 700W! Box is 33ltr and heavily braced with 4” rear port. Finish is heavily stippled and applied with a roller. Xover is at 2KHz. Bass is not super low and requires a subwoofer for better bass. Speakers work extremely well with my 0.5W 1920s tubed amp. See the forum thread Beyma, a Spanish coaxial driver for more information.
