That's great
. BUT you seem to be implying that the speakon connection and the amp/sub connection method is inferior. Which, I believe IF you were able to set up your sub with that method, you would find the
opposite. Simply because your connector is faulty
OR you have not connected the cable correctly at the amp end ( no grounding) doesn't invalidate the set up. BTW, IF you amp is balanced, ( I have an ARC tube amp
that is set up this way...) the connection is NOT the same as suggested in the sub manual. You would again need to talk to Sumiko or the amp manufacturer for their set up recommendation. ( It is
VERY odd that
the manual for these subwoofers mentions
NOTHING about this issue
).
