Do I need a sub woofer to match my ATC SCM11s


Hi,
I love my speakers (ATC SCM 11s), but am wondering if adding a sub woofer would better my experience? The speakers are on stands being driven by a Hegel H160. Any suggestions/tips to further enhance my system would be greatly appreciated.

JL D108 would be another option. Unfortunately great subwoofers aren’t cheap. 
A subwoofer is not a panacea to that thin sound that you describe. You should check out a Spendor floor stander. They have a footprint the same size as a stand mount.

if you love your speakers, ATC makes great passive and active floor standers...

Fair enough. I think given the choice of adding a sub or replacing my speakers with floor standers, I'm inclined to lean towards adding a sub. after an  exhaustive search for speaker stands, I found a really nice match that really enhances the look of the speakers and I paid about a grand for them, so my preference is to keep them (please see for picture of my speakers and their stands). The enjoyment of sound is the most important quality and if it makes sense to get floor standers, then I'll make that switch. All things being equal, what is the smart choice here?
