Design

The woofer is a 12.5 cm cone type with a newly designed polymer-coated fiber cone. The cone maximizes diaphragm area and reduces distortion. The high-frequency driver is a 5 cm cone-type tweeter with a paper cone. The crossover network is optimized to improve sound integration between the woofer and tweeter. The enclosure is bass reflex with an oak-like finish.

Market

The J50 was sold new in 1995 for ¥24,000 per pair in Japan. Some users have reported that aftermarket foam surround rings don't fit correctly, which can make maintenance or restoration harder.
