Just a note, when we compared the M22s and M50s, it was on the harder rock (probably worse!) recordings that we listened to. At higher volumes, the M22s were somewhat more difficult to listen to. This jives with your recollection, correct, Peter and Adam?

I'm still waiting on mdrew's sibilant recordings so i can compare the M60s to the M40s. I can weigh in with another opinion on some of the Axiom speaker models, the brighter vs the M40/50 line hopefully soon.

In the meantime, i will use some of the recordings i've found to be sibilant and do some listening this weekend.

Ken, you recommended the Metallica disc w/ that "sandman" song. I burned it and returned it, so no damage done.

Huh. Been awhile, I guess. For a bit I was recommending S&M, but none of them are particularly well recorded. The remaster of Master of Puppets is pretty good, but I haven't heard that on Axioms.

Skerdi, I think a STEREO GRAPHIC EQUALIZER would do the trick. You could pump up the mid-bass for warmth and cut the sibilant frequency which is below what the usual treble tone control covers.

Sibilance does not come from high treble.
Anyone can make a regular S sound sibilant just by holding the letter sssssso that everything sssssounds sssssharper with sss notessss.

I've done the M40 vs M60 test for sibilance with mdrew's original recordings that he had complained/asked about. I'm going to do a listening test with my big Tannoys and the M60s later today. In a preliminary test with the Tannoys, the sibilance from mdrew's recordings is still present. The recordings definitely have alot of "s" sounds. However, the remaining question is, do the Axioms enhance this more with their forward sound?

The beauty of a "brick & mortar" store is that you can listen and directly compare speakers side by side before you buy them...something everyone should do.
The M50's can rock but I felt the bass was just too weak no matter how I placed them. I think the problem is the dual port configuration. Upping the bass control adjusted the wrong frequency.

Were you running with a sub? I only noticed a lack of bass without a sub on recordings with very low frequency stuff. 'Course, I only run with a sub now that I noticed that.

A good tweeter (like the Axiom's) reproduces what it is given. I agree, the sibilant frequency is lower than that which is covered by the treble tone control.

No...I have no sub.
