Speaker Floor Coupling

Mechanical coupling with mechanical coupling the stage or floor is excited by vibrations from the cabinet or by the acoustic output from the speakers port.

Speaker floor coupling. I have several floor standing speakers. By making the speaker a part of the floor to the greatest extent possible the vibrations from the speaker do not get pushed back into the enclosure. Jim smith is well known in the high end is author of the set up bible get better sound and is also now writing for copper. Hence isolating the speaker from the floor might mean some other changes in the sound due to reducing the floor vibrations.

If you have a floor which is made out of wood however which can easily transmit vibrations you will very likely prefer to decouple your speakers so they do not have further vibrations transferred to them. Funnily enough people will use spikes on a concrete floor or will place coins or specially made washers under their speaker stand spikes so they don t pierce their wood floors which defeats the purpose of coupling altogether but still helps to decouple. And non resonant meddite mdf construction with extra bracing. On one pair i took the cheapest solution as a first try before considering spikes and cones.

When this happens the floor itself or stage becomes a resonating surface a bit like a massive drum skin or giant. Wooden floor is alive coupling decoupling the speakers or. Quality crafted cabinet design. Coupling your speaker to the floor coupling is a technique that seeks to minimize unwanted resonances by increasing a speaker s connectedness to the ground.

As you can see getting a proper understanding of sound speaker coupling and decoupling is not as difficult as it may seem. Why getting your bass cabinet off the floor may help your tone august 29 2017 25 comments if you re a bass player who rolls a heavy speaker cabinet to the gig and once the cab is on the stage you turn the cab on its side or remove pop out casters.

Strong rigid and acoustically inert enclosure reduces unwanted internal standing waves for less audible coloration.
