CORAL 10L-1

Commentary

This 25 cm cone type woofer unit was developed as the second product of Coral's L series.

Alnico magnet is used for the magnetic circuit.

Around 1965, 16 Ω model and 200 Ω / 400 Ω high-impedance model were sold.
It seems that only the 8 Ω model was sold around 1970 which is the latter period.
