Condition: The speakers were serviced by DALAUDIO, crossover capacitors checked, level controls cleaned, drivers confirmed and auditioned. These are well performing speakers for their age, relatively efficient, but in our humble opinion should not be overdriven. We auditioned them with a DALAUDIO Studio LM3886 Amplifier (58 Watts/Ch.). Units exhibit smooth bass with extended midrange and high end. Overall, a bit of surprise for a 45 year old speaker. The cabinets are very good overall, the grills have some pilling, but are very usable in this condition. Please see all photos.
A bit of audio history: Ohio based Maybern Sound Reproduction Company filed for, and received, the Synergistic brand name in 1979. RTR was one of the largest speaker manufacturers in the country, and also supplied drivers OEM to other mfrs as well. In particular, they were very well known for their dome, mids, tweeters, and ESL panels. In 1981, they moved manufacturing to the RTR complex in Canoga Park California. Synergistics was Mayberns own well-regarded private brand designed by RTR's and sold by Audio Warehouse, and Tokyo Shapiro among others. Audio Warehouse became the largest Audio chain in Ohio.
This pair was sold by Tokyo Shapiro (as marked on the box). They were shipped from Synergistics 8116 Deering Avenue (also known as RTR Headquarters!) in Canoga Park Ca. so likely sold in 1980s after the RTR move.
