I was using all Ricci's measurements to be equal and the UXL-18 is the closest to the Cap driver but with a little more X-max. Now I am just talking SPL and nothing else.
You guys can reproduce anything you want, I just want everything on the disc. When a person records sounds you bet there is low frequencies, the crew decides what they want, some leave it on and some don't. I want to produce or recreate the films that do. I have plenty of 20hz and above as well. Again why do we just say 25 hz is enough? I mean that contains 98% of material so why bother with the 1-2% at all. You says 99% is enough but not 100%? It does not cost that much to get it. It does require measuring and boosting. Oh yeah, of course 75-85 dBs at 10 hz is hardly noticed, I am talking 120-122 dBs at 10hz, try feeling that an let me know if you want it or not. I would not even bother with a sub for 75 dBs at any frequency, heck, dialog is louder than that. We would not even considering Captivators or JTR for 75-85 dBs!
No offense, but I'm not seeing anyone contending what you're iterating above. And certainly no one stating that 25hz is "enough".
If it matters, I'd say sub 15 hz content represents FAR below 1% of movie audio and virtually NONE of music, never mind 2%, and getting 10hz reference-level playback DOES come at a cost: namely displacement/space, amplification and monetary expenditure- especially for those not able or willing to do DIY.
And I wasn't attempting to unequivocally compare different tests, but simply wondering how much power was presented as we all know that a doubling or quadrupling of power provides for more output, all else being equal.
Further, I would argue that the goal shouldn't necessarily
be "producing everything on the disk"...because that operates under the assumption that what's being recorded actually inherently
contains those frequencies. I don't have any links handy at the moment, but it's easy to find that many recordings contain frequencies that are NEVER "naturally" present in the source. There is, for example, NO human voice that produces a 12hz freq but it has been detected in a few vocal-only recordings.
Should that be reproduced? I suppose it's a matter of perspective (it's important to understand that there ARE distinctions to be made, here) or even "taste", but I'm not going to tell someone they can or cannot pursue it. That's important.
It- imperatively- is not to say there are NOT other sources of sub 20hz sound that are completely "legitimate" (read: inherent to what's being recorded)...then the "debate" centers around not only how often, but how meaningful it is. And again, I don't think anyone is saying people cannot pursue it.
The real problem is, if I make speak bluntly, that some speak so matter of factly about "reproducing the disk" or not so clandestinely implying that those who cannot reproduce 5-8hz at 115dbs are not serious about a "real" home theater experience. I'm not being flip, the tone and insinuation is clear and present on many threads and conversations just like this one. This of course accomplishes nothing other than what other ego-maniacal, posturing, "I'm superior" male behavior does: inciting conflict.
And make no mistake, there are some on the other side of the fence who do the same...identical result.
