Commentary

This speaker system is the successor to the slim design Model304.

The Model304/2 is configured by adding a woofer to the Model303/2 which is a sibling machine.

Two 20 cm cone type woofers are installed in the lower range.
By making the woofer unit a parallel drive, the enclosure size is kept slim while the low-frequency playback capability is enhanced.

A 2.5 cm soft dome type tweeter T33 is mounted in the high range.

The enclosure is hermetically sealed and has a walnut finish.

The stand was sold as a separately sold option.
