Test Bench: The Peerless by Tymphany PMT-40N25AL01-04 Mini Full-Range Driver
The 1" diameter full-range drivers are among the most used transducers in consumer electronics. They are finding broad use in numerous Bluetooth speakers. The driver submitted by Tymphany for this Test Bench fits into that category. The Peerless by Tymphany PMT-40N25AL01-04 is a 25-mm (1”) diameter full-range driver built on a proprietary injection-molded two-piece polycarbonate (one piece for the motor assembly structure and one piece for the protective grill).
