I'm not quite sure that I fully understand your question, but I will say that a good suspension will definitely isolate a turntable from footfalls and other vibrations. A stunt I use to prove it to non-believers is to hit the suspension of my Basis Ovation turntable with a hammer (covered with cloth to keep from marring the suspension, of course) while a record is playing. None of the energy from the hammer is transmitted through the speakers. While my prior (non-suspended) turntable, a Well-Tempered, was pretty good at isolation due to its mass, it still could be affected by vibrations from heavy footfalls--it clearly could have benefited from a device like a Vibraplane or Seismic Sink, but they cost more than the table and arm itself.
Suspensions on turntable...really effective?
Been wondering about this, so did some research, but was surprised I couldn't find any that categorically says that turntable suspensions really isolate/substantially reduce outside vibrations, resonances, etc.
Any reference out there you can point out?
Cheers

Basis uses a combination spring and fluid damped suspension in my table and I believe most of their line. AJ Conti (the man behind the company) has many technical papers about his products on his website, including the suspension system he uses--since you asked for it, see this link: http://basisaudio.com/docs/SuspensionTP.pdf There are plenty of other ways to design a turntable, as evidenced by the many fine products out there; this is AJ's take on the subject. As I posted before, this suspension is very effective, IMHO.. |
