Multiple binding posts on loudspeakers

Lets consider the rear of our SR58 loudspeakers and why we have fitted 3 pairs of binding posts. Being a 3 way design, means the speaker has separate bass, mid and tweeter transducers mounted to the front panel. These are wired to an internally mounted passive 3 way crossover and then out to each pair of binding posts at the rear of the speaker cabinet.

Flexibility We could have used a single pair of binding posts, but in using 3 pairs, the loudspeaker can be more flexibly fed and wired. Lets say you already have a hifi system and want to purchase the mighty SR58 speakers, but feel that your existing system is not capable of optimally driving the new speakers. So do you sell your existing hifi system and purchase a larger one or do you keep your system and simply purchase an additional power amplifier? The good news is that there is no need to change everything just to get into the SR58's. You can keep your existing hifi to run the mids and tops and by using the pre out function on your existing hi fi sytem, you can purchase and feed a separate power amplifier to run the bottom end only. In this instance you would link the tweeters and mid range binding posts together to be run from your existing hifi, whilst the bottom end would be wired separately from your power amplifier. 

Taste There are all sorts of amplifiers out there and some users have a predilection for valves. No problems when using the SR58. You can use your small valve amplifier to drive the tweeters and your Perreaux integrated or power amplifiers for the mids and bottom end.

Single, bi and tri wire You can link each set of binding posts together and run a single pair of speaker cables, alternately you can bi or even tri wire to suit.

All things considered, you are far better off having a loudspeaker with multiple binding posts with separate access to tweeter/mid and woofer elements, as opposed to a single pair of binding posts with the loss of access, flexibility or control.
