I wonder if Jim can hear the difference between sapeli and sycamore. I wonder if anyone else can.
The thickness of the veneer is barely a millimeter, hardly enough to make a difference. The design of an enclosure is so that it doesn't resonate. Otherwise is would be an acoustic enclosure or instrument, one designed to resonate and add overtones. This is the last thing a speaker designer wants.
Are there differences to be heard between woods? In the world of acoustic instruments, 100% yes. Is there a difference in the sound of metals in acoustic instruments? 100% yes.
Thanks Doc (95bcwh), but my hearing is perfectly fine. I can hear a gnat fart at 30 paces in a forest at dawn.
This proves nothing I'm afraid. It still doesn't say anything about your ability to perceive things. Some of the most sought after recording engineers have holes in the frequency response of their hearing, and suffer from tinnitus from years of exposure to high SPL's, but can still function very well. Beethoven was practically deaf towards the end of his life, and some of the works he did during that period are considered by many to be some of his best.
From what I have read, there has NEVER been any proof that a wire or even an amplifier can exhibit any differences. Once the levels are correct and balanced, it’s all the same, according to ABX.
I don't know how many white papers you've read, but there are many on both sides of the fence. I don't see you even hint that there might be some validity to the other sides findings, which demonstrates that you have an inherent bias.
Even Frank Van Alstine himself has gone to efforts to test whether it's plausible, despite his experience as an electrical engineer telling him otherwise, he still tried it for himself. I am sure however, that he can hear differences in the different amps he makes. Otherwise he would still be selling the first amp he ever designed and not gone any further in developing new ones.
The NRC ( National Research Council ) here in Canada has done quite a bit in the field of audio testing and has accumulated some interesting findings. The place is filled with Phd's. I know some people who've had to use the NRC for scientific analysis (in other fields).
Here is a link to an interesting one that pertains to speakers, and explains a little more about the NRC :
