I think the real issue here is why do some speaker designers provide the option to biwirebiamp. If biamping is so great, why do some high end speakers.
Biamping is using two separate amps, one for highs and one for lows, using an external crossover. Whoops just broke my own rule 2 benefits of biwiring is speaker dependent. Biamping involves the use of two separate amplifiers however, which deliver separate voltage and current to the bass drivers and midrangetweeters. And though it may seem a little intimidating at first to experiment with what works for you, dont forget that your end goal is all about achieving the best sound that fits your preferencesand to have fun while youre figuring it out. The voltage drop is almost neglible anyway unless your running something like 50metre lengths to your speakers or speakers that are so low in ohms they require a massive curent draw.
In initial research we where open to the possibility that biwiring could potentially lead to better sound, since our multiconductor cable design easily facilitates such configuration. So, whats the difference between biwiring and biamping. What receivers definitely support biwiring or biamping. Biamping is a different kettle of fish, and although you may get variable results and opinions depending on speakers and amps, i found that biamping which necessitiates biwiring to improve the dynamics of my source material. Biwiring in the absence of biamping is widely acknowledged as being a waste of money and effort. By having this set up, you are forcing the tweeter currents and the woofer currents to run in separate cables. I also bought front speakers that support biampingbiwiring. Biamping, of course, is a different consideration, but this is not biamping, it is biwiring and it seems that nobody has once offerred up any evidence that shows that real world audible differences will occur when using a good piece of 12 gauge wiring vs. While im skeptical of biwiring, i have no problem with the idea of biamping, which is done all the time in mixing rooms and sound studios. Some speakers may benefit from biwiring, particularly those which have a tweeter with a higher impedance than the woofer.
At its root, bi means two, and it relates particularly to the axiom m80ti and m60ti tower speakers, which are supplied with biwiring terminals. From what little research i did, biamping makes sense, but biwiring does not. The only difference in this case is that you run 2 signals to each speaker, instead of ruuning just one signal with a biwire cable from one speaker pair a or b and then. Ive recently purchased some new equipment, onkyo txsr608 to be specific. These models feature two pairs of binding posts on the back of each. To make the matter worse for noobs such as myself, some sources indicate that sometimes the term biamping is incorrectly used.
The terms biwiring and biamping short for biamplification continue to confuse lots of stereo and home theater fans. Active biamping involves the use of an active crossover which splits the electrical signal into high and low frequencies.

This is when you use multiple amps or channels on amps to power the tweeter, mid, and woofer separately on speakers. You have to either have speakers that are made to be biamped or you must modify them remove the crossover and add a second set of speaker terminals. Also, if the speakers impedence is low 4 ohms, would biwiring in a a, b setup help or hurt the amp it seems like it might hurt instead of help performance because the amp has to work harder to drive the 4 ohm speakers, and then you put the. And there is a lot of work to set up the system to make it play correctly. This technique can allow users to take advantage of the strengths of each amplifier in its interaction with the speakers i.
