So how many people are using subwoofers

My Jaguars on their own are pretty strong to the mid 30s. Adding a pair of Titan IIs makes all the difference in the world. It isn't just the added last octave, it is the openess and increased sense of "ease" over the whole upper bass and even into the lower midrange. The soundstage is also significantly expanded and at the same time more focused! I use ACI's passive 85Hz line-level filters in front of my main amp. The Titan II crossover is actually set around 50Hz. You'd think this would result in a hole in the response, but instead it greatly eliminates an otherwise obnoxious room mode at around 70Hz. The bass is far tighter with the subs in the system.

Im not 100 percent sure on this but I beleive that in music all notes carry some bass in them regardless of frequency. Maybe its not so much the note but the the sound of the string off the wooden guitar or the way breath resonates off of a reed. I can tell you that a good sub will add to the entire spectrum. Recently I added a second sub and the difference was more like a cable upgrade then just adding bass.

Powered subs for music, not a good idea. They always mess up something. I have used Stereo Rels, Genesis 928s and single Vel HGS 15, Bag End Infra, Paradigm 15 etc. They always mess up something. Shut subs down and listen for a WEEK, I guarantee you will prefer naked. Eggleston Fontaines, Tyler Reference, Paradox 1s to name a few I have tried with subs.

Many say they prefer monitors w/sub ??? Monitors generally have no mid bass punch and are small sounding, adding a sub and you end up with no mid bass punch, small sound, but some added low rumble.

GOLD's statement may be more of a commentary on the REL than on subs in particular...my friend just hooked up a REL sub to the MUSICAL FIDELITY amp and said the sub sounded "WOOLY"...that is "kinda sloppy..not tight...not hifi"...and its possible that the built in amp has something to do with it ...so Dennis may have a point as well...i would love to A/B the famous REL with the brand new line of subs from ADIRE appropriately called the BRAMHA SERIES...10,12,15...and a monster 18!!...the 12 weighs like 40 POUNDS!!!adire audio.com

SCRATCH the ADIRE...replace with the UTOPIA line of subs from FOCAL the 11,13,and 15 inchers
