Should I bother to try a subwoofer?

Having owned a pair of REL Stadium 3's for approx. 8 years, I can say with certainty that all of the above posts recommending a REL sub(preferably 2)are spot on!!! As recommended, cross it/them over low and don't turn 'em up too loud.

I doubt Kenscollick has ever heard a GOOD sub used for music. He doesn't know what he's missing. They add much more than just additional low frequencies. As mentioned, they really open up the soundstage, add power and weight to the music, and all the little nuances and musical cues come through more clearly.

Just my 2 cents!

Subs are great for affects , I leave mine off for music . Subs are for people that buy the wrong speakers .

I had Dynaudio confidence 3's (similar in bottom end spec's to your speaker I think) and went to Vandy 5a's with internal 500wpc powered subs.
For me getting the bottom end of the frequency range reproduced at appropriate sound pressure levels was really a big deal and added a lot of enjoyment.
A caveat is that you really need sub(s) that allow themselves to be individually tuned to blend with your speakers and to react appropriately to room resonances, otherwise you are buying a boom box that is maybe only good for movies or whatever.
In my opinion.
Still miss the Confidence 3's sometimes. Seems like every good speaker has certain songs that really make it shine.

"Subs are for people that(dont' you mean who?) buy the wrong speakers." That's the dumbest blanket statement I've read on this forum in a long time!

Yeah...this subject seems to engender some weirdly snarky responses to what is a basic reality: Subs make the lower freqencies audible. Is that so wrong? Also there is something to be said for the imaging capabilities of small baffle speakers that don't have much bass combined with a good sub (like a REL) that can be a magic formula, without having to spend $97,000 on a pair of Rockports (speakers...not shoes).
