Vandersteen 2WQ Subs and ARC Power amp

Just purchased a pair of 2WQ subs in very good condition.  However, the variable crossovers that came with them were single ended, so elsewhere I purchased the fixed balanced versions, marked with "150K".  The seller assured me that was the proper value for my ARC REF 150, which has an input impedance of 300K.

I have very little, if any, output from the subs when I use these crossovers.  Do I have the wrong values for this amp?

Vandy subs are very subtle in performance.
When you plug them in, do you hear a 'Thump'. If so, good! They are working.

150K crossovers should be giving you noticeable bass, considering the amps 300K impedance, but perhaps your room needs a bit more 'punch'.

When in doubt PM John Rutan (Audioconnection).
Mr. V will also respond via phone iquiries. Just call Vandersteen and leave a message.
Either can give you the best information.

Another thought...
Which taps are you using with the ARC?

I do hear a thump.  And if I disconnect the main speakers and just listen to the subs, I do have very low level output.  This is beyond subtle though, all the way to nearly dead.  Unless I just need to get used to these....

Another piece of info, there seems to be little difference in output level with or without the crossovers.
