So I found a sub for a decent price locally and I am curious if it will compliment the current setup There is a Klipsch rsw10 locally for I believe $175 Will that sub do any good with my klipsch rf7's,rc7,and rs7's Or should I hold out for a better bigger sub when it pops up Any thoughts would be awesome Also I currently have just a little Yamaha v757 running everything till a good deal pops up on a good amp. Thanks as always Ron
