Product information "Scan-Speak 12MU/8731T00"

The Scan-Speak 12MU/8731T-00 4.5" Midrange woofers are based on compact under-hung motor systems with large neodymium ring magnets. The patent pending motor offers a very long linear excursion together with a very high force factor. The top plate is shaped to “guide” the backside airflow around the motor and with the very open cast aluminum chassis design the driver is virtually free from compression.

The under-hung voice coil is precision wound with CCAW ribbon wire on a titanium bobbin for a low loss yet high power handling design. The vented pole piece has contoured openings to eliminate any hint of turbulence noise. The uniquely shaped top plate and open air frame ensure there is virtually no dynamic compression caused by restriction of the diaphragm back wave.
