Japanese-made 3-way bookshelf speaker with hermetically sealed cabinet and multi-amplifier input support
Overview
The Pioneer CS-700 is a 3-way bookshelf speaker system made in Japan by Pioneer Corporation. Note: it is unclear if 'Pioneer CS-700' and 'Pioneer CS-700G' are the same model, and the facts here are explicitly for the 'CS-700G' variant. It has a 30 cm cone woofer, a 12 cm cone midrange, and a multi-cellar horn-type tweeter for the high frequencies. The enclosure is thick particle board and hermetically sealed, so it is airtight. The finish is walnut oil, and the grille is brown fabric.

Design
The CS-700 uses FB cone diaphragms for both the woofer and the midrange, plus the multi-cellar horn tweeter. The cabinet is thick particle board, hermetically sealed. A 3-step switching type level control is built in. Multi-amplifier operation goes through dedicated rear terminals, and a switch turns them on. The outside is walnut oil with a brown fabric grille.
