In Reply to: RE: "I heard them in the lab room at my company's factory..." posted by Ethan Winer on May 13, 2009 at 12:47:34
Yes, Ethan, like duh, but the (D) next to my posting name means I am a dealer in this industry. Because we sell acoustic products including the Cathedral Panels, ASC, Echobusters, etc., I took your 2 year old critique of the Cathedral product and their documentation seriously and followed the earlier threads and exchanges between you and the manufacturer very carefully. I have been very direct with the manufacturer in this regard and they have been very forthcoming in return. I respect their responsiveness, willingness to acknowledge that the third party that ran the original, since withdrawn waterfall plots, goofed, and they didn't catch it (you did), and their willingness to offer even you, their most vocal critic, the opportunity to retest using a testing methodology that works with their product.
Why don't you address the questions (such as when you say you "heard them in the lab room at my company's factory" are you talking about hearing test tones or music?) instead of getting personal? I can get personal too if you insist.
I love the part too about my needing to quit because I am not an engineer. Hey, at least, unlike you, I have used the products I referred to (Cathedral Panels, Shakti Hallograph, Roomlens, Synergistic Research Acoustic ART, as well as the "conventional" ASC and Echobuster products). At least I admit what I don't understand, instead of insisting that if I don't understand it, it can't work.
Anyone is welcome to share their opinions, but you claim to be an expert, and you beat everyone up with it that has differing opinions (or, sob, who isn't an engineer). Don't you have to have basic experience with the products being discussed to be an expert on them?
So if I am a "shill" because I have actually used the products and like them, what exactly is someone who trashes them unheard because they don't fit your set of comfortable theories?
Follow Ups:
I don't "beat people up" when they disagree with me, at least not if their disagreement is legitimate. I've learned a lot over the years from people that disagreed with me. But this is not at all like that.
In this case the product is too small to be useful, even if it did work. But it doesn't work, so it's not even minimally effective. Claiming these panels work on "new physics" that defies the large body of current knowledge about room acoustics is sophomoric and disingenuous.
A good example here is Auralex LENRD bass traps. The absorbing material they're made from works well enough, but they're too small to target low bass frequencies. They still improve a room at least a little at higher bass frequencies, which can be easily heard and measured. Versus Cathedral panels that do nothing beyond placebo effect and wishful thinking.

Nobody called it "new physics." Quite the contrary, as was pointed out, the Venturi effect is very old physics. Since the first up when I Google it is Wikipedia, I will post that link below.
I think the only "wishful thinking" here, is your wishing that it didn't work because that would challenge your stuck in cement attitudes.
Assuming that your having avoided the repeated questions regarding your claim to actually have listened to the Cathedral panels means that in fact you did not listen to them, maybe you can stop repeating with emphasis that it doesn't work unless and until you actually have some listening experience with the product in the real world, by which I mean with a music or video system.
And if you want to test it in your lab, at least try the methodology suggested by the manufacturer. Just a thought.
Which leaves us right back with the fact that everyone who has posted on this product after having actually used it, and every reviewer who has actually reviewed this product, liked it.
Since this whole thread started with someone asking for opinions on his room, maybe we can leave it on this note, and suggest that if he is interested, maybe he can test with a money back guaranty - ask a dealer.
I know I am worn down by the whole interchange.

Ya think?
BTW, I did listen to music in the room that day with the Cathedral Panels in place and heard no effect. They don't work. They can't work. Wishing they work will not make it so. Convincing a few people that they work also does not make it so. Some people are convinced they heard an improvement after "demagnetizing" their vinyl LPs. That doesn't make it so either.
Okay, I'm done. :-> )
