Townshend Springs under Speakers
Man...this thing is still being discussed....wow...if you needed springs, I would think the speaker manufacturer would have provided them or somehow implemented them into the design. Still ain't putting slinkies under mine. My tannoys sound great as is....I thought the same about my ATC's. It's unfortunate that this thread has become about personalities rather than the topic under discussion - because the Podiums actually work as described. |
Ok, "My Turn"... Anyone here with an abundance of experience in this realm of study, "And there are quite a few of them about". They all know at least one thing about this subject for sure. And that is, that there is simply not any single, "One thing". Whether, "device, method or practice". That will truly (solve) this issue with ANY combination of, "floor, flooring, room, speaker and etc.". There are simply too many variables. But understanding a few concepts. Along with a bit of experience implementing the several basic ways we approach problems of this nature. This helps us to narrow down "Hopefully" towards what is that "best formula" to utilize in improving a systems properties. A bit more quickly. Sometimes this is easy. Sometimes not. And sometimes, "We just get lucky"! Or at least I have felt like that at times over the years. One thing I have also learned is that there is simply "No substitute for mass". Speakers with little mass. "Regardless" of cost, space-age technology and the designer/engineer's reputation? Those "Low mass" speakers will always sound like they are in fact, "Low mass speakers". At times the best of them may, "At low energy output values" sound pretty good. But once at what most, (99%+) would call a reasonable output in an avg. environment? They begin to ring, vibrate, resonate and dance to their own (now) distorted voices. Which is all the same thing. Just differing verbiage. In the effort to make speakers smaller, lighter and with with as few materials and mass as possible? Many modern speaker, "Designers" have fallen prey to their marketing divisions wants. If you simply calculate the energy your transducers as a whole are going to output at your reference listening level. It is not hard to then take the overall weight of a given speaker as one value. And then translate the energy output of the transducers, "Minus the energy lost in heat exchange, voice coil friction, Air friction across various interior surfaces and etc. etc.". And then, Each speakers weight must then be translated into a form and then value, which after calculation must be in excess of the energy in inertia against which it is being forced". (The dead weight of the speaker). (Which is sometimes, but not always, "An applied force In a single direction") or "vector of force". So that you may in turn find that your, (Tiny, plastic and nearly weightless "Bose" speakers) may be at best, "problematic". I'm just throwing that out there. Doing my part. Trying to help. |
Robert - Sound Engineer for SST
Ok, Just to be clear, I had skipped ahead and over the above referenced gentleman's posting. But I did just read it. "In it's entirety", and, "Twice"! Wow! And I could not agree more. "With all of it". And I also admit that I "Wish" I had his "Abundance" of experience which is truly of considerable nature. Anyone here simply discounting his words above? Or arguing the points of fact which he made? I believe you do so at your own peril of remaining in you own "Bliss of Ignorance". He took what "I" have found in my own exp. to not just the, "Next level". But "Several levels" upwards. So, A big, "Thank You" > To, Sir "Robert" - "Sound Engineer for SST". |
@jollygreenaudiophile2, you're a bit late to the party. As posted earlier by @nonoise this guy would probably be able to explain better: https://www.youtube.com/watch?v=aW2LvQUcwqc |
