Talk:What is bi-wiring, and should I do it/@comment-31022905-20171228223026

Edit after re-reading my own 'article':

The reason bi-wiring in some cases may still 'improve imaging' (as i think someone mentioned in the thread), is when your speaker actually does have electrically completely separate high-pass and low-pass sections in its XO-circuit. This in fact means each cabinet houses two independant XO/speaker units, resulting in four independant speakers (albeit caught in two cabinets).

Now if you 'bi-wire', that is, run a cable from four separate amplifier outputs to connect each of the four speaker units, you will obtain (in the case of stereo through two-way cabinets) a four-amp-four-driver setup. Now that each driver has its own amp, you will get some (though not the most significant) advantages of bi-amping. In other words, it gets better, but because you bi-amped instead of bi-wired.

At least now the amplifier will see four separate loads and, depending on amplifier output stage topology, will behave differently as compared to seeing two separate loads (as in: two drivers connecting at a XO-circuit, connecting to a single binding post per cabinet).

Still, most of the advantages of the one-amp-per-driver setup, as described in my previous post, are lost if the amp doesn't connect directly to the driver. So, if you have a passive circuit after the amp, like you do when bi-wiring passive two-way speakers, chances are any improvement you perceive is imaginary. Which is fine btw, since you perceive it, right?

Just so long as you realize this perception is caused by expectation bias, you will not get into a fight with any electronics engineers.
