Default MR13P vs MR16P distortion

After a lot of research and head scratching, I finally decided on the Satori MR13P for my home theatre 3-way LCR speakers. I'm currently really bothered by the high distortion levels of my of my 2380 horn, so want to be absolutely sure that my new speakers will not have this problem. I find distortion in the vocal range very audible.

I came over some distortion measurements of the MR13P, and comparing it to MR16P measurements from the same source, it looks like the MR13P has some excessive distortion at around 1.4Khz. 2% at only 92db/1m.

Is the MR16P a better driver for 350-2500Hz operation as indicated by the measurements? I would prefer the dispersion from the smaller driver, but low distortion is a higher priority.

I've build speakers with the MR13/16, own a few Satori speaker kits and also a pair of JBL M2/2435HPL + Acoustic Elegance TD15M-Apollo.

Whilst I am a huge SB/Satori fanboy I dont think your combination will work well.

Just for kicks I measured (umik+REW) the distortion levels of both systems and the AE/JBL combo was way lower in distortion than the Satori TW29R+MW16, something like -70db vs -45db.

IMO the difference in performance is also too much for them to mate well.

I'd suggest the Acoustic Elegance midwoofers to match to the 2380.

I am replacing the horn with a mid+tweeter combo. Trying to decide between the MR 16/13.

Ah I see.

I preferred the MR13 to the MR16 for a more integrated midrange and so long you cross high enough (300hz and up?) the distortion levels are better than the MR16.

Acoording to the tests done by audio press, the MR13 has significantly more distortion then MR16. Have you experienced the opposite?

Before giving up on compression driver, it might be VERY worthy to investigate better horn than the 2380.

Try a round tractrix or JMLC.

I really want to try a different horn, but i can't find any readily available well designed 2" horns. Closest i can find is the H2EA, but it closed a bit small to be crossed at 800Hz.

Havent compared side by side, both sound equally good to me. My diy friends prefered the MR16 after studying specs and being a newer driver it could well be the improved midrange satori driver.

If it would be Satori, then maybe the MW16TX would be a better choice for midrange. The TX doesn't have the elevated distortion and frequency response suckout between 1-2kHz like the paper Satoris.
