Celestion Ditton15

Commentary

This speaker system is the top-of-the-line bookshelf type of the Ditton series.

UL8, a 20 cm cone type woofer, and ABR, a 20 cm planar dron cone, are mounted in the low band.
The ABR uses a special double structure that uses lightweight and rigid synthetic resin for the diaphragm and is held by a neoprene double roll suspension.
The operating mass is precisely designed and tuned with the woofer. In addition, the low-frequency output of opposite phases below the fo of the woofer and a sharp drop in low-frequency output, the ABR always vibrates in phase with the woofer and enables playback in the low-frequency range below fo.

The HF1300, a 3.8 cm dome tweeter, is installed in the high range.

There were two variations of the enclosure finish : walnut and cheek.
