The BBS-10 is unusual and rarely seen system consisting of headphones and seat-back sub-woofer, along with an amplifier specially designed to drive them. Text copyright © Walkman Central. Unauthorised reproduction prohibited.

Clearly this was not intended to be a portable system, the amplifier took its power from the mains and the sub-woofer had to be experienced while seated in a reasonably sturdy chair. The idea behind this was that the listener would not only hear the lower frequencies, but feel them too. Text copyright © Walkman Central. Unauthorised reproduction prohibited.

The BBS-10’s purpose was apparently as a sales tool to help sell the DD-100 by showing, amongst other things, the advantage of DOL (Dynamic Optimum Loudness). Text copyright © Walkman Central. Unauthorised reproduction prohibited.
