These are Martin J. King designed open baffle speakers with 8 inch Tang Band 1808 full range drivers over 15 inch Eminence Alpha full range bass drivers.

The Tang Bands are powered by Paramour 2a3 monoblocks of 3.5wpc while the Alpha bass drivers are powered by Emo/Dayton monoblocks of 150 wpc with built in crossovers set at 80hz.

I'm using a Conrad Johnson preamp to control the four amps in this system. Signal is from an Integra DPS-7.2.
