To optimize power and equal power distribution, the number of BKs in a BK system needs to be an even number.
When the number of BKs in the system is an odd number, a “Dummy Load” should be included as a final BK to make the total number even.
A Dummy Load is a BK transducer with the internal moving mass removed.  The coils are still active, but there is no shake from the Dummy Load
Dummy Loads are not offered for sale on our website.  If needed, please email help@thebuttkicker.com to order.
