Best way to connect Rythmik f12 with Parasound a23+ and Vandersteen 1c's

Yes assuming your amp has five way binding posts, preferably with holes for bare wires. 

@tomic601 I had a buddy with some decent speaker wire so I now have appropriate lengths of 14 awg w/banana plugs out of amp and into vandys; almost the same length of comparable wire out of holes in 5 way binding post (screwed down tight w/no exposed wire) from l/r speaker out's to bare wire eagerly awaiting the sub that goodwill has yet to ship out...

moved some stuff around and I now have a good amount of room behind and left of the left vandersteen that will host the F12..around 4 feet from corner of the room.  I AM READY!  likely my one year old son will want to play with it so i'll have to think of some sort of baby proofing..

will keep posted w/results

Awesome…remember to check out Vandy owners forum , lots of Model 1 owners there…. ;-)

The results are in: the rythmik def adds a lot of weight and space to my system...I think it integrates well on a low pass setting the gain at around 60%.

Im a happy camper and had no idea what i was missing, not that the vandys dont have nice bass extension but the f12 digs down lower than 20hz.  Adele 25 sounded great...Red hot chilli peppers UL shone as well.

Really glad for goodwill auction, thanks for the speaker level input advice @tomic601 

Wonderful !
