Pioneer CS-05

Commentary

A non-directional speaker system that does not limit the listening area.

In the CS-05, the woofer is mounted downward at the bottom of the enclosure and the sound is radiated all around with a diffuser. In the middle and high range, the sound is covered all around by installing three tweeters at an axis angle of 120 ° in three directions.
This realizes a non-directional speaker that can be installed anywhere.

It is equipped with a 20 cm cone type woofer for low range.
FB cone is used for the vibration plate of the unit. In FB cone, the fiber is not crushed as in the conventional method, but it is molded in the long state, and it becomes a soft cone paper. This cone has high transient characteristics and efficiency due to its small mass, and moreover, its internal loss is moderately large, and its characteristics are flattened.

Three 7.7 cm cone type tweeters are installed in the high range.
The unit is located at an axis angle of 120 ° and provides high-sound energy throughout the room.

The enclosure is a bass-reflex structure with three pipe ducts arranged in the direction of the axis angle of 120 °. The inner part is made of sound absorbing material made of glass wool.
The exterior has a walnut oil finish on all sides, and it is designed with a round grid grill and black grill net to emphasize the beauty of the design.
