Commentary

A speaker system that uses the same unit as the Model 940 floor-type speaker system with a bookshelf enclosure.

The Woofer uses a 12-inch holey cone, the Skoker uses a 5-inch one with a back chamber, and the Tweeter and Super Tweeter use an LPF dome unit, originally developed by Marantz, which is a diaphragm dome with minimal distortion and good sound.

The enclosure has a strong assembly structure with tight internal reinforcement to eliminate unwanted vibration and interference with the unit, and is finished with an oil finish by hand polishing.

The front baffle of the system has ports cut and sealed, usually with urethane foam filler. This allows you to fine-tune the low-frequency playback depending on the state of the listening room.
