binding posts
If your speakers have 2 pairs of binding posts each, connected by the ubiquitous metal plates, if biwiring or biamping should you remove the metal plates or doesn't it make any difference?
@mazian I think if you’re bi-wiring (2 sets of speaker cables, one amp) or bi- amping (2 sets of speaker cables, two amps) you’re right, you don’t need jumpers. That said, I had good luck to my ears replacing my stock brass plates (~$4K pair of speakers) with quality jumpers (one amp, one set of speaker cables plus one set of jumpers). Ymmv.
In short answer to your question, definitely remove the brass plates if you’re bi-wiring or bi-amping. |
One thing more to mention , myself and others who are Audio-Electronics techs have measured quality of connectors ,did you know over 80%/ use lower quality Loudspeaker terminals Loudspeakers ,as well asAmplifiers they use gold plated brass , which is brighter , and 3x more resistance, as as as that in lower conductivity. Just look up the metals index Silver around a 67, Copper 65,brass 22. I have changed all connections to WBT ,or Furutech throughout my Audio system which is a Big difference in fidelity ,this too includes Rca , and very overlooked The IEC input most use cheap $3 inputs when the Furutech are retail $30 gold over Copper ,not zinc,brass then tinned ,meaning you are creating 3x+ more resistance which = distortion before you even start x the 2-3- or 4 components in your Audio chain . In Audio Everything counts ! This is where you start ,and BTW these biwire setups on speakers most are Fake , true bywire the wire from theXover goes to the topend-mids and lower terminal Bass if you just unscrew the plate you can see , most have all wires soldered together inside which is more a marketing ploy then a true Bywire setup. And the metal terminal connectors on the majority hurt resolution ,much better to have true jumpers wires with quality connectors . i was selling them for awhile but most people don’t want to spend the extra $$ for top quality -Everything in the chain is cumulative ,keep this in mind .i have been anAudiophile over 40 years have been modding speakers for years and owned a Audio store for a decade, trial and error ,and many good techs have help me ,these are tips more then anything else, It’s your gear to do as you wish !! |
No. You can damage them even if the polarity is correct. Two amps will have slightly different output voltage levels for any given input. The difference exists between the hot (red) terminals of the two amps. The shorting bars short the two sets of terminals together. So if one is driven at a particular moment to 30 volts and the other to 25 volts, you have 5V/ zero ohms = infinite current from one amp to the other. remove them. Bi amping allows you to choose one amp that is good for high frequencies and another that is basically a ballsy beast for low. With bi-wiring there is no danger either way.Bi wiring simply allows two sets of wires to connect to the two. Its pretty subtle. But, removing the straps minimizes cross-drivers impacts (e.g.: the larger back-emf from the woofer) from impacting the higher frequencies. I suspect its a very, very, very small impact.
