I don't have time to post the pic's, maybe tonight when I get in, but when I look at what Sonor did with the Designers and then look at what Premier did with the Signia's, (I hold these two as the top level kits of each manufacturer in a similar era) I clearly see why Signia's resonate significantly more than Designers.
At first glance, the drums look identical (a Signia drum and a long lug Designer).
A closer look reveals the completely different type of ISO being used. In size, on the lug mounts, and in design on the tom holder mount. Premier used no ISO mounts from holder to shell. It is attached to the rods of the lug mounts.
This is not to say one is better than the other, I love Designers, and not everyone desires all the resonance Signia's provide, it's just to point out the significance of this ISO stuff and the part it is playing. In my opinion anyway.
If (like in SONOR's case) a hole is drilled and rubber is covering the metal part, the sound vibe will surely be a bit absorbed by the rubber. So, the more rubber You have, the more isolated the tom is, but also, the drum is more choked. At least that's my point of view.
Premier Signia shells should vibrate more and have more sustain, if there's not that much rubber on the inside, under the screws...
I (think) I understand the german concept of drum making - the idea is to get the best performance, monitored on an oscilloscope. And the oscilloscope picks up the vibration from the head (since it's connected to a microphone). So, in the end, what You're after is a clear sound, not a lasting sound.
It's the same with cars - if You pass the point of sound isolation, where You can't hear someone's horn when You're inside the car, the result is obvious...
Just my 2 cents regarding this...
All that wood-metal touching and vibrating gives something to the drum that we seem to forget nowadays - liveness!!!
Now we like a smooth action - we seem to forgot Bohnam's hihat in the "Since I've been Loving You"...
