?? Well at least half my tweeter got a nice shot :-) ...

Man, that was impressively fast! Awesome.

Interesting how Seth's grey speakers still look purple. I like them no matter what the lighting. Very nice finish. Sent from my SCH-S968C using Tapatalk

I wondered whom would be the first to mention this. I didn't want to toot my own horn about it, so I let it ride. This experience utilized my Cecropia project I recently constructed.

I have 5 different coils in the woofer circuit, and 6 different coils in the tweeter circuit that I can switch in or out at will, as well as a shorting switch on the 3rd order cap on the tweeter to change from LR4 to a BW3 acoustic response. I did inform the crowd what I was switching in terms of circuit, but not the parts involved. Nobody knew my preferred before the setup, nor did they know what was being used.

I know I played the following, and I think it was the order, along with switching in and out of BW3/LR4:
14 Litz on both; this is my preferred, and I started with it. Crowd just listened.
14 air on both; Crowd said a 'dryer' result in sound.
14 foil on woofer/12 foil on tweeter; nobody liked this.
Returned to initial setting for comparison.
15 P-core on woofer/16 Waxcoil on tweeter; most did not like the bass.
Initial setting again.
18 I-core on woofer/Air 22 on tweeter; one person liked tweeter, all else did not, but most liked the bass. One asked to set tweeter to initial setting, and leave the bass from this one.
18 I-core on woofer/14 Litz on tweeter; This was the crowd's preferred setting as a majority, while the LR4 was preferred for most recordings, and BW3 for those that preferred some vocal enhancement. The bass is a bit emphasized with the I-core over some others, but I guess the general consensus as a whole is bass is good, no matter how much.

Some comments:
Dan says he preferred the Litz on both, and at the BW3 setting. Matt agrees. I like both the LR4 and BW3, as a source-dependent setting. I find the BW3 can be a bit shouty sometimes, where the LR4 is not.
Rory said he likes that I do this sort of demonstration thing, as he always comes away having learned something.

I'm glad it was informative, as it was a challenge to emulate and create. I found it solidified my hunch that coils do indeed sound different.
Later,
Wolf

Belated thanks, Ben -
Wonderful test and knowledge transfer.
Even those of us that were/are unable to make the trek can benefit from the accumulated experience.
Now looking at purchasing some I-cores and Litz inductors for my projects.
Hmm, maybe PE can treat you like Troels - just give you a couple of boxes of high end crossover components.

I might do resistors next year, even though I've done some minor testing before and couldn't tell then.
You're welcome,
Wolf

Belated thanks to Ben & Company for putting on another great show. I really enjoyed listening to all the unique and interesting designs. I agree with most of the sonic commentary; these were some of the best sounding systems I have heard to date. I was initially sitting in row 2, but had to move because the room was "booming" like crazy. The dance studio at MWAF doesn't seem to do this at all, so I am going to set my subwoofer just a "tad" higher when I get to that venue.

Craig, you are correct. I was in error when I told you that these speakers would look "grey" when properly color corrected. Actually, any object takes on the color cast of the light source in the same way that speakers take on the sound coloration of a listening room. Those speakers look "purple" under tungsten lighting (2300 degrees Kelvin with zero green/purple tint) because something in the texture of the surface reflects this color back when exposed to tungsten lighting. Since I put a tungsten "gel" on my flash unit to match the tungsten overhead lights, the overall balance came out much lower than daylight.

But this is not to say that "gray" is the "correct" color. The speakers look "grey" when exposed to daylight balanced light (5500 degrees Kelvin with zero tint). But they should and do look "purple" when exposed to tungsten light. Both colors are correct. Hope this helps.

Sorry about that, Eric. I always seem to miss a speaker when racing through the editing process. I don't have access to the HD with all pictures on it right now, but I will go back and find my full length shots of your speaker. I am sure I took several shots of it. When you see me at MWAF, tap on my shoulder, and direct me to the speakers you want covered. I always seem to miss something.

Eric,

I e-mailed 3 High rez pictures of your speakers to Bryan and Ben. Below are the low rez versions, which I capped at 150k each for posting. If you want the high rez versions, send me a PM with your new email address. The one I have on file returns an error message. Thanks.

Ahhh, there's my babies! Thanks Bill, I'll shoot ya my email.

That Scimitar design is totally awesome, the woofer layout and driver choice is inspired

Regarding the YouTube videos, I would love to see the audio for the speaker introductions restored, even if the music can't be included.

I thought I removed the copyrighted songs to restore the audio back....! Which ones are muted or are all of them muted? I will check again....

Most of the speakers design can be found in the forum.... and all the designers are here.
