Volt DVC251.7 Dual-voiced Bass Unit

 10" Dual Voice Coil Paper Cone Centre Bass

The DVC251.7 has been developed for use in home theatre systems to enable  accurate reproduction of bass frequency effects.  It uses a long voice coil and symmetrical field, double magnet system for exceptionally linear cone excursion. This enables high level reproduction of extremely low frequences with maximum fidelity and impact. The dual 8 ohm inputs allow use with passive crossovers to augment an existing system or they can be connected in parallel for use as a 4 ohm unit on the bass channel of a 5.1 system.

The Thiele-Small parameters are optimised for easy use in relatively small enclosures to give extended bass performance.
