"William Sommer******"
I did do my research properly, because I knew I would be subjected to this
crap. Did you look at the B215 link I supplied? The B215 is A POWERED
SPEAKER, and the 1/4" phone jack is a balanced input. READ WHAT IT SAYS on
the Details tab.
** The B215 is a passive speaker - as stated at the top of the first page
of the link.

Says: " * 2 professional speaker connectors (compatible with Neutrik Speakon
connectors) plus ¼'' jack connectors."
The "details" tab give you a different model - the B215D which
incorporates a class D amplifier.
The OP made it VERY clear which model he was on about.
