First things first, thanks for the links to Capricornkid's information as folks lose sight of the amount of effort that goes into a "simple" exercise such as comparing two different subs, graphing and posting and annotating the results. A sulute to Capricornkid for his efforts and your's for forwarding the linked information.
With the above in mind, I feel that I'm being backed into a conversational corner based on the graphs posted. So allow me to ask, what are you wanting me to take away from the posted graphs? The reason I ask, in a sound control room, one doesn't place the slider positions to flat because they use the sliders to EQ the sound to flat. Yes, later in the thread, Capricornkid attempted to do just that and EQ out null and reinforcements.
(The Velodyne, SMS-1 looks like a nice add for one who likes to play
In the first couple of graphs, what I saw was opposite to how sound tracks are mixed. Short of being willing to jump the fence, go all sound crazy and start doing measurements myself, realistically, I'm in no position to be a "true" critic of another person's thoughtful effort. All I can do is kickback and sincerely say; thanks for the efforts.
My attitude is: "Walk the walk Chuck or put a cork in it." That sort of cleaned up conversation and for your understanding, after thirty plus professional years of not being appreciated, I've sworn myself to mediocrity and refuse to ever jump the fence again. Philosophically, I'm a pragmatist and in cases of sound and art, believe that purity of action is a sign of insecurity. I say Photoshop the bejesus out of the image as it's an image, not sworn court evidence and I say, when one can, in the reproduction venue, EQ the heck out of the track. That's the beauty of having an AVR with XT32; we have XT. As you pointed out in the provided link, my thinking, if there's a 40HZ null in the room (A reading note, the 80Hz signal was bumped in both and didn't show as a harmonic null) and one has the ability to bump that 40Hz slider the necessary 3dB or 6dB so as to flatten the curve, then without hesitation, one should reach right over and make it happen. Whether in a performing arts venue, a sound recording studio or sitting at a THX movie mixing board, I have no conflicts with this type of behavior as that's what's being done by all mixing crews.
Allow me to repeat myself so my thought isn't unintentionally lost in my above ramblings: "So allow me to ask, what are you wanting me to take away from the posted graphs?"
I'm not knocking your thoughtfulness when I post, personally, I'm looking for waterfall graphs and spectrographs as opposed to a linear EQ graph. What I took away from the posted information was, if given half a chance, room acoustics will eat reproduced sound alive more than what the capability of the two subs were. Yes, I read your very interesting and insightful comments regarding the design differences of the two subs; a snapshot of your comments below:
"NOW this isn't to say the BIC PL200 is bad. To the contrary. Some might prefer this design decision ---where it stays clean at loud volumes playing demanding source material. But the Klipsch is definately more accurate to the original source, and if kept within its limits --- the more desirable sub, at least in my strong opinion."
In truth, there is no accuracy to the original source as everything has intentionally been colored from the choice of instruments and strings to the choice of venue treatements, to the personal preferences and mood of the mixing crew, all of which has been colored by everybody's personal bias'; taught thinking. What happens when everybody's signal is EQ'd flat; at the pre-out and in the room?
An aside, to counter the room eating the sound, I use Fluid Dynamics and see sound as if waves of water in the room. Makes it much easier to visualize the invisible and hopefully, counter the behavior of the room's need to eat sound.
A note, should I get the Jones, after installation of the new subs (when money comes available,), just for giggles, I'll pull out the mic and scope the room. Should make for a month or two of healthy, Alzheimer's delaying entertainment. Looking forward to your reply on what I should take away from the linked information.
And FWIW, yes, overall, I would consider the Klipsch, RW-12D a better choice over the BIC, PL-200. But then again, in the same light, I'd consider the SVS, PB12-NSD to be a better choice over the Klipsch, RW-12D as in the end, it's all about available budget.
