Johnmcelfresh, If I was sounding condescending, it was because you started putting words in my mouth, and were missenterpreting what I was saying!!!
HOwever, your 25 years of owning a turn table and a pair of speaker, plus some Stereophile mag's on the coffee table, don't tell me anthing!...nor do I care!
Show me your accomplished track record of custom theaters and I'll be impressed..I've worked on hundreds, plus $1million dollar installations, for large clients! I've been trained by the best in the biz, consult on setting these things up for a living, yada, yada...so you can discredite me all you like. I can put together world class systems. When you even setup "one speaker" properly in your room, come talk to me. If so,TEll me your proceedure? Let's see what you know. Then you can tell me how it should be done.
Till that time THIS GUY IS REFERING TO "ACTIVE SUBWOOFERS"! I hate to inform you. He might not has specified, but he's infering "powered subs", not some passive boxed woofer-weirdness...lol.
And, BTW, most separates sub modules, sans the amp and crossover, are really active subs anyway!...the gear is just outside the box, that's all..same thing.
Still, to reiterate, YES, EVEN A PAIR OF OLD DEFINITIVE BP2000'S WITH 15" 1000WATT ACTIVE AMPS DRIVING THE BASS, WILL STOMP ANY WILSON GRAND SLAM, JM LABS UTOPIA FULL RANGE, or anything else you can think of that's passive, even being driven by, YES, Bolder 1000watt monos!!!!!...graantee it, every time!! How do I know?
Because, I've been there, heard that, tried that, installed/set up that, and it's not as good! It's called LEVERAGE AND EFFICIENCY! AGain, passive crossovers suck engergy, limit control over bass woofers, and don't offer even remotely the kind of control that "dirrect coupling" does!
So you can skirt around with semantics all you want! Active subs are what people need to do this right!
They can rinky-dink around with their full range setup. But it's not as good, setup properly.
Go sell THX and Lucas Film your BS! They'll tell you the same.
So, yep, I'm sure some bum under the overpass has some tv stereo speakers sitting in a shopping cart, who swears he's got a THX sound from a console television....that doesn't mean it's truth for the masses.
