I love your arts and crafts home, and even though I only heard them once, I think that those Silverlines (I only heard the 17) are classics. I recall when they came out and had good reviews, and next thing there were always a few pairs for sale, but then that ended and they are now rarely available, and I think that it’s because owners are keeping them. I would love to own a pair.
ribbons vs domes and sibilance
I came upon a thread from the DiyAudio site titled "Can you have sparkling treble but without sibilance?" from 2011. The discussion is very technical and as such, completely over my head but one participant asserted that ribbons are far less prone to sibilance than domes.
Here's an excerpt for the technically minded: :
... the middle of the dome basically flops about doing it's own thing at high frequencies as it's only very loosely coupled to the edge because of it's own less than infinite stiffness. Thus any distortion or resonances that occur due to the middle of the dome bending and moving in non-piston ways are not reflected back to the amplifier via back EMF... when the ribbon is only 8mm wide compared to a 25mm dome, there is far less narrowing of dispersion with increasing frequency than a dome. The directivity control is achieved with a wave-guide instead. This is why a wave-guide loaded ribbon can achieve an almost constant 90 degree horizontal dispersion from 2Khz right up to 20Khz - the ribbon element itself is far less directional horizontally at high frequencies than a dome, with the wave-guide then adding in a constant directivity control.
I'm wondering whether any forum members have compared speakers with domes and ribbons in regard to sibilance and arrived at any conclusions.
