I have posted this one before.
This D2 is from a vertec, not the M2 labeled version.

I use a 2435 modified with aquaplass and ferrofluid that sounds better to my ears. Also measures smoother,...

I expected there to be some phase plug fuzz aswell. I will measure more this weekend to be sure, but I don't hear anything wrong during the sweeps. After hearing a few 100 sweeps on this horn I...

I recently got hold of a pair of 2435 HPL drivers and was curious to see how they do on the M2 waveguide.
I thought maybe some others here are as well...

The 2435 drivers use a 3" Beryllium...

Interesting POS. Thanks for puting it up.

Can you tell a little bit about your measuring routine; What distance and what kind of gating is used?

To measure the crosover properly you need a...

Good observation POS.

Here is a comparison between my Dayton UMM-6 using the individual calfile provided by Dayton, and my Behringer ECM-8000 using a generic cal file (based on the data you just...

That is a good point.

I should check with a different MIC.

I don't think an anechoic chambers or outdoors is necessary to measure this area precisely as I can use gating to eliminate...

To all owners of the M2 wg and D2430K:

It would be interesting to see measurements from others using the EQ/crossover values in POS google docs document. See https://goo.gl/GdfQ7N

I have...

Yes I have compared a SEOS 18 (1.5" version) and the M2 WG with the D2430k, and to me the M2 WG is a better device.

In short:
Lower coloration (subjective), smoother more consistent response...

You could be rigth... I really need to get them outside.

But it can also be a diffraction effect. There is a dip on-axis in JBL's on axis mesurement aswell @ 2kHz.

But most likely room...

For some reason my REW measurement file from before was lacking some of the measurements I used in the listening window I showed earlier
Therefor I made a new set of measurements.

I was more...

The baffle size and baffle diffraction affects the off-axis response in lower frequencies. The speaker is much taller than it is wide, so I guess it is natural that it is somewhat different.

If...

Sure I can post them tomorrow when I get home. :)

I agree about the German magazines polar plot, looks to narrow down low.

My version of the listening window response is an average of 0-10-20-30 horizontal and +/-10 deg vertical.

There are some sources of error here, as I don't have a dedicated measuring facility....

Since you helped me out I took out my MIC again.Below is a picture that illustrates the "issues" I have/had.
- This is an on axis measurement at 1.5m gated.- The red curve is the orginal XO/EQ...

Thank you so much for pointing this out POS. This is a bit embarasing. I had completely forgoten about the input EQ!

This fits perfectly with my measurements. I have a few minor bumps in the...

I see what you mean. I also don't really think the 18" + 12" midrange combo is justified in this concept. JBL has done alot of work to making it work as a 2-way.
It is mostly because it was what I...

Good remarks as usual POS :)




All in all, I think my testing/build might be a little too far off the original M2 to discuss in detail in this thread. It might be confusing to those who really...

I am using the 1201 from 130hz up to 800hz.

1201 really wants to be crossed around 200hz, but the subwoofer I'm using at the moment isn't usable that high, so I EQ the 1201 on the low end. I'm...

I finally have a prototype with sound using the M2 waveguide and the D2430K. Only one channel though. TAD TM-1201 from 800-130hz, a comercial ported sub below that.

First impressions: The M2 is...

Has anyone figured out the best way to mount the wave guides to the enclosure?

There are 10 holes on the back that can be threaded, but then you need access form the back.

How is it done in...

Awesome! Thank you.

That is the original flange, the one that was not in stock when I ordered the waveguides. Looks like it is now. Thanks for making me aware :)

I was curious if this guy 'sebackman' had an...

Is this universal adapter for sale somewhere? Is sebackman a forum member?

The adapter wasn't available when I ordered the waveguides. I was hoping that maybe someone could share the dimensions of...

Thanks!

About the 1201 3-way mentioned, What potential benefit do you see in this arrangement? (I also own a pair of TM - 1201's)

Does anyone here know the exact dimensions of the M2 waveguide?
