I have the L1 Model 1 AND a pair of 802 series2 with the 802 c controller. When I am using the 802 system exclusively (no L1 involved), can I use the controller in bi-amp mode and feed the b1s using my 802 system?
The B1 Bass Module is designed for use with the L1 system. Although it is physically possible to connect the B1 to a controller and amplifier for use with other products, we can not guarantee performance as these components were not designed to work together as a complete system.
If running the 802 II's at full range is not providing enough bass for you rapplication you may consider adding a 502BP bass enclosure.
