Default Monacor SPH kevlar midranges

I've been trying to find some test data around the web for the SPH135KEP or SPH165KEP kevlar drivers, without luck. Especially interested in distortion and off-axis measurements.

Monacor's datasheets suggest the on-axis response is extremely smooth up to ~10 khz, I wonder if there's any truth in the datasheets..

They does look very smooth
But SPH-165KEP seem to have a dip around 6khz but falls off smoothly, and with a moving mass at 17g it seems very likely, but definately an interesting driver
SPH-135KEP....what I doubt most is its rated sensitivity at 89db

Vedo, thank you a lot!

I kinda suspected that.. The off-axis response isn't all that great and I wouldn't cross it higher than 2k5. It's a 6,5"driver , so a lower crossover point would be probably better anyway.

Is the T/S data measured by this magazine? The moving mass seems way off, 12g against the stated 17g?

Yes it is accurate, at least on the two 165KEP I got.
Fs is more around 45Hz than the stated 30Hz.
The response is smooth up to 5/6Khz with little breakup.

The only concern with this unit is that a high volume, there is an air leak around the plug, which makes some noise.

Response:

THD at 1kHz (meas of my speakers, crossover at 3kHz):

And my speakers:

Crossover point IMHO could be at 3kHz and below. It is a great driver, I think it is better than vifas 18cm xt/xg.
If you need I have meas of: 165c/cp, 130al and prapobly 200ke.

I guess I would "attack" it around 4khz (6db with double RC)

Question exact dimensions

Does somebody have more precise dimensions of the SPH-135KEP or maybe SPH-165KEP would aslo be adequate. I ma looking at theese drawings and can't make much of them: http://www.monacor.de/de/PDF/G/G1/G102410/G102410Z.pdf
What does 133x133 mean? Is it 133mm measured at units narrowest point or at the wide part.

Thank you in advance
