Thin Walled Speakers -Tonian, Musical Affairs, etc


Hello,
It seems that a few speaker makers are using the thin walled, lightweight, less damping approach to building. For example Tonian, Musical Affairs and some others.

And I've read some very positive reviews of such speakers. I can see how they would sound unreal with vocals, acoustic instruments etc. But how do they sound with other more spectrally complex music- lets say rock. Do they turn to sonic mud?

I'd be curious to hear feedback from anyone who actually owns or has heard such speakers.

Thanks

I have Tonian Classic 12's. I can assure you that the speaker does not turn the music to sonic mud when playing rock or orchestral works. You might not like the sound of PHY based speakers but it would not be because of its lack of detail or coherence. I consider these traits one of its strong points.
Light weight and less damping do not go together; the BBC "Thin Wall" design was based on designing a cabinet with a resonance at a less critical point and then damping that frequency. Not easy to do; requires skill in design and building. Can work very well if properly executed but simply making the cabinet thin and cutting down on the damping is likely to give a colored sound. I currently have 6 pairs of the "Thin Wall" construction as well as others of heavier construction. Actually my S 100s weigh around 80 lb. so thin wall does not mean light weight.
I have Tonian TL-D1s and yes, they can rock without the use of a mudroom. Even electronic fare like Trent Reznor's and Atticus Ross' soundtracks sound wonderful, varied and nuanced.

Just because a speaker is designed/voiced like an instrument, it will still give you a gratifying listening experience. In all genres.

Granted, it may be off a bit, but what isn't? What matters is, is it convincing enough to allow you to suspend belief?
With the Tonians, I always leave my brain behind.
