Its always the metal dome speakers that cause SSSSSSibilanThx
Better cymbals sound and sibilance (metal dome)or no sibilance and not so good cymbals (soft dome).

You're using 'passive' LC cross overs no doubt?
High pass for the tweeter. Low pass for the sub. Band pass for the mid.
You still cannot beat the natural resonance of wood enclosures though right?

Resonance (when entity A = B / corner frequency)
It is the cancellation that counts right? Complex stuff speaker box design.

Beg to differ. IME, metal tweeter Totem Forest + bi-amp'd Arcam A38/P38 = sibilance-free zone.
A pair of Totem Forests, yesterday
I prefer silk, have not noticed any sibliance. Cheap metal tweeters canbe a problem.
Don't always look for the obvious - most tweeters are pretty well behaved through the sibilant region, it is however at the point where bass/mid drivers generally break up which can cause a "hissing" sound. It can be controlled but will depend on the design of the speaker/crossover as to how much.

Is this where active XOs come into their own?
And today's winner of the wooden spoon award is....
We do so many shows in a row,
And these towns all look the same,
We just pass the time in our hotel room
And wander 'round backstage,
Till the lights come up, and we hear that crowd,
And we remember why we came.
Too much analysing on this site, just listen to the music!
I've heard that the Forests are supposed to be very good... did you demo them?

There is a theory, common in another place, that suggest that sibilence and other higher frequency harshness is caused by tweeters that are opperating at too low a frequency, remember in two way designs the bigest challenge is to roll off the bass driver before the cone breakup becomes too severe so tweeters are used down to frequencies at the limit of their abilities. I think there is some truth in this.
Low order crossovers are an issue too, the tweeter rolls off slowly and can still be producing significant output an octave or more below the crossover point, distortion produced at these frequencies is usually harmonically related and manifests itself at higher frequencies, harshness, sibilence etd.
Many metal dome tweeters are speced for use at lower frequencies than their soft dome counterparts, a big part of the problem in my view.
Ladies and gentlemen, dear friends,
I honestly didn't see this one coming. I mean: whaaw! I'm so happy. It's so nice to finally get credit for all my efforts and devotion.
I want to thank all my friends and family who supported me when things got difficult. Most of all I thank my lovely wife. Ingrid darling, you were always there when I needed you; I never could have done this without your ongoing support and love! [gets emotional and starts to cry vigourously...]
Let me be the last to offer my congratulations.

Sorry DocG, it appears that once again my humour falls a little flat.
I thought that introducing active speaker techology into such a thread was an excellent and amusing wind up on your part, hence the 'wooden spoon' award.
It would appear that no one else took it that way.......
Well you get a wooden spoon for coming last so it didn't make any sense.
