Horn vs. Waveguide

[Salas]

The mains in that pic you posted are positioned so you can’t get reflections off the console at mix position.

I hate NS10 monitors, and always change them if they are there.
Yes, meter bridge mounting is a problem. We agree!! Yay.
Probably better to mount just behind the meter bridge, and depending on what’s in front of you, could avoid work surface reflections.

Take into consideration that the environment is changing rapidly, and console or work surface footprint is diminishing. In some cases, like I mentioned, a mastering room might have little or nothing. And I suggested this might be a good application for the Gedlee monitor.

If you see what I have said as criticism, perhaps I was responding appropriately or in-kind; but I’ve tried to take what you’ve said at face value as best I could.

I'm glad you took the time to find out about Hendrix, a lot of people don't know him these days. Hey, even I was young at that time ...LOL.

Those multicells in the pic aim surely at the desk area by large IMO. How do they aim away, when the operators are mainly right there mixing, I don't get it.

Anyway studios are getting better its true. And big names in studio consultancy can push new trends. I will be happy to see some ESP15s in a prestige facility, installed by you. It will credit you back for sure. No purple haze in their dispersion patterns for sure!

Interesting double there...

Well, I am not a studio designer, though I have worked with design firms as a client, so I am familiar with the process. But thanks in advance anyway.

With the big Smith-horn monitors, just look at it geometrically, the reflection off the console should be below the engineer's head. Now off of the small piece of real estate called the meter bridge...could be a problem, though looks like it goes above the engineer's head. I can't tell from a pic, anyway.

Gonna layback and let the science guys riff.

I just looked up the definition of "sockpuppet" in Wikipedia

Interesting.

I'm sorry, my mistake. I appologize, it was Macka that was being so rude. I won't respond to that.

The only place that you can here these speakers is here at my home or in Bangkok, Thailand.

Earl,

I was not being rude.

As you know you are on an open forum and you do NOT have the luxury of your own web site where you can project anything you like without feeback except lack of sales.

My point is you made the statement about the studio environment (which flys in the face of everything) without any factual scientific support information because it suited you to do so at the time.

Your have a nasty habit (as a scientist) of doing that.

I have no issue with you promoting your idea but please dont make misleading representations for the purpose of creating a following.

I posted from a friend's laptop bcs I was absent and forgot to log out his name. Then I posted exactly the same from my account so it is obvious it is me. My post came up first bcs the other account got moderation delay since he never posts, just reads.

I am a member from 2002 here. You should wait for an explanation Magnetar. Thanks. You are quite suspicious. But be open eyed too and see that I would not have made a carbon post with my nick if I intended to use an alias! BTW are you Romy the cat of goodsoundclub?

Magnetar = Romy. Aha! Now I know why they've never been seen in the same room together.

 

[soongsc]

Here you are.

Thanks,


Now there does seem to be a similar noise trend in the noise between the JBL and the wave guide when first posted.

Baffled & passive EQ'd:

Multi resolution spectrograms

.... are very nice

are there any tests with known systems?

Unless the windowing and graphics are just right it is harder to know what is real and what artifact, without some reference.

Unfortunately I don't have access to the software used, or would test it myself.

Hello

I threw a wrench into things. Two are EQ'd number 1 and number 3. It seems that some of you are using the high frequency roll off in the some of the plots as part of your determination as to which is which.

What is unique in the time domain between a Wave Guide vs. a Horn?? Are there tell tail artifacts in the CSD's that can be used to see the reflection back into the horn??

I would assume them to be shown and the longer decay rates that seem to be a intervals that are tied to "holes" that appear and then dissapear as the time interval increases.

I am going to attach an non-EQ'd plot for number one and post pictures for the horns and waveguide to but a face on them so to speak.

Thanks for your input

Rob

 

[Robh3606]

Here's number 1. It is a JBL PTH1010 waveguide. I know Earl will take exception as it has a pronounced diffraction slot in the mouth. It is rounded and not sharp edged but it's clearly a diffraction device.

Rob

 

[gedlee]

Actually it is not clear from the photo that it does have diffraction. But I would say from the unEQ'd plot that it does. It is clearly head and shoulders better than most diffraction horns.

 

[Robh3606]

Here is number 2 It's the exponential horn. A baffled 2307/H91 horn used in many of the vintage JBL systems and in the 434X large format 4 way monitors. The measurements are without 2308 lense in place.

Untrue as all of the other posts have attested to.

Your opinion.

I have no issue with you promoting your idea but please dont make misleading representations for the purpose of creating a following.

I don't

 

[Robh3606]

Hello Earl

I am calling the narrowing in the throat a diffraction device. I assumed that any narrowing or impingement into the horn that obscures the drivers throat qualifies. Is that correct??

Rob
