You all will be mind-boggled when you hear the AK6- new Klipschorns. Imaging and musicality is staggering, and both PWK and Edgar would be grinning!!!

...the benefit of using two subs is obviously smoothing out the room, but also you can turn each sub down so they are "loafing along". This helps with definition. I have found that the appropriate crossover in my processor to my RF7IIs is 40 Hz for music. 60 Hz delivers more wallop but I have to turn the subs down. Right now the sub setup I have is tuned to make the most of 20-40Hz with a combo of R115Sw and SW115. When those deep deep notes in music or effects in movies come along they are startling! And yes I too test the patience of my dear wife. After dialing the subs in, I had to go to the kitchen cabinet where our wine glasses are and separate them so they weren't touching each other. oh yeah, much better ;-)

re: the new models ? "Oh ye of little faith!" the SW311 is a little monster and a smart one too

Actually... my father's parents are from Quebec, so there is a family thread I'm sure... I found out later that my Dad's first name (on his birth certificate) was Joseph, even though he went by Roderick. It adds up, because I am a bass freak

interesting thread! We have a few exceptional tracks that we use for Klipsch Inc.subwoofer development (hint), and one of my favorites is a Telarc recording of Michael Murray. Needless to say, quality recordings of pipe organs serve as dynamic, brutal and fantastic test tracks. But with that said, one must hear/feel an actual pipe organ in all its acoustic glory, in a large cathedral or concert hall, to grasp the room shudder of the lowest notes. A full body experience. And a lofty goal in audio reproduction for subwoofer designers. get ready --Mark Casavant

I wish they had shown the hand hammering K craftsmen. A bit of old world with new.

funny we just got another Maximum PC Kick *** Award for the wireless ProMedia 2.1 system. A nice anniversary present.

what is matched up to these as main speakers?

and.... in order to get additional 6 dB of output you have to keep doubling surface area (with double the power assuming the subs are the same model) 1 sub + 1 sub = 6 dB "up" (this is the most economical bang for the buck improvement.) 2 subs + 2 subs = 6 dB "up" 4 subs + 4 subs = 6 dB "up" This was the premise of the ProMedia SWS concept, which not everyone understood. Ultimately, the simple benefit of going from one sub to two is a large advantage gained... "Doesn't everybody have 16 subs??!!" ;-P

thanks haus (Trey) ... another thing to remind folks about is that loud bass is pleasant, and it needs to be loud to truly hear/feel the infrasonics...~ 20 Hz. So whoever thinks 110-115dB is enough, that's fine. The ear (no dude, not you/ the human ear) can tolerate more without pain or damage, and in nature bass gets pretty loud. But there are true bass junkies here and those that appreciate clean and loud, which is the hallmark of Klipsch and one of the very reasons we entered into the sub category in the first place.

this is not really fair but, I thought it was still relevant due to some of the prices people are wiling to pay for flat extended bass... This is the latest version of my RT12d + RSW15 combo. no mods to either product... One thing I did since the last round was balance the output from the two, so each works less hard. ARC is active for both, obviously...

yessir. that's the plot I asked for ... now you know why, homeslice ;-) .... it's called 'optimally flat'

I would recommend the front right corner, which will help smooth out room modes. This will make the frontal bass impact better as well. 'boomy' huh? try lowering the crossover setting a bit. I am a purist about rears subs. If you're going to add one in the back do it only after you have two in-phase across the front. and the rear sub should be tied to the rear (large surround speaker setting) signal to really not detract from the multi-channel presentation.

the bottom graph is a measurement of just the RT-12d. plenty of real output at 22 Hz and up....

keep in mind it's half space measured specs listed above. Typical home envirnment is 1/4 or 1/8 space which equates to room gain on the lowest frequencies. with that high sensitivity you could EQ it to a degree and get useful bass extension at 30Hz. I own two for PA purposes, and as I have DJ'd with them in large ballrooms and put the power to them, they are visceral and very good sounding/ low distortion tuneful bass/ not the typical droning of most PA subs. I limit the power at 20 Hz as they do come 'unglued' 'down there'... where some new heavy dance music resides... the passive radiators unload and have a flapping sound. if anything it is an audible governor and I back them down a bit, all the while the 18" drivers are protected. But that is when I am dumping 2500 watts peak into them. I would *never* play them that loud at home... on the other hand you may ultimately spend more $ to tune them appropriately for home use, and defeat the great deal.
