Bi-wiring - Hogwash?
I have a pair of speakers that support bi-wiring and bi-amping. I only have
one aplifier. Will I appreciate any improvements in sound by bi-wiring alone? |

No. The really dumb thing is that there's still a crossover inside. Separating the drives for each speaker is only interesting when you have multiple amps and electronic crossovers. You can fine tune the crossover, isolate clipping, and use amplifiers with different powers and qualities. This is why subs are often driven from a separate Class-D amp. |

It actually really depends on a lot of factors...it's possible that instead of using a crossover, each speaker has it's own high-pass and low-pass filter respectively. That would seem to make more sense because that allows for bi-amping without an active crossover at some point in the signal path. What it really comes down to is the wiring inside the speaker cabinets. Your best bet is to calculate the load that your amp will see in both situations. If your amp sees a lower impedence with the bi-wiring (a likely possibility since you are forcing parallel wiring on the drivers), your amplifier will have to do less work to produce more sound. You will also want to check the specs on your amp though to make sure it is designed to handle the lower impedence. Matt Leonhardt |

Amplifiers are a constant-voltage source, so the amplifier will produce whatever current is required to achieve the necessary output voltage at any given instant. The only possible advantage I can see with bi-wiring is if one of the drivers (the woofer most likely) draws so much current that the voltage drop in the speaker wire would otherwise affect the voltage going to the other drivers. Bi-wiring would then provide a dedicated run for each driver to the constant voltage source (the amplifier). However, unless you were using severely under-rated speaker wire, I would expect this effect to be miniscule compared to all the other effects that adversely affect the sound (the speakers themselves, the room, source material, etc.). |

Will I appreciate any improvements in sound by bi-wiring alone? No. The really dumb thing is that there's still a crossover inside. And you won't achieve any improvement by using two amps either..... Separating the drives for each speaker is only interesting when you have multiple amps and electronic crossovers. You can fine tune the crossover, isolate clipping, and use amplifiers with different powers and qualities. This is why subs are often driven from a separate Class-D amp. It actually really depends on a lot of factors...it's possible that instead of using a crossover, each speaker has it's own high-pass and low-pass filter respectively. That would seem to make more sense because that allows for bi-amping without an active crossover at some point in the signal path. What it really comes down to is the wiring inside the speaker cabinets. Your best bet is to calculate the load that your amp will see in both situations. If your amp sees a lower impedence with the bi-wiring (a likely possibility since you are forcing parallel wiring on the drivers), your amplifier will have to do less work to produce more sound. You will also want to check the specs on your amp though to make sure it is designed to handle the lower impedence. The above is mostly garbage. Speakers designed for biwiring normally do have separated ground returns on the crossover, which is the same as saying that they have separate low-pass and high-pass filters. It's still a crossover. However, because it *is* a crossover, there is *no* parallel operation, hence the overall impedance is *identical* to a single-wired configuration. Let me repeat that - biamping as described above is *not* parallel operation, the impedance is *not* lowered. As someone else noted - remove the ? in the thread title for accuracy. -- Stewart Pinkerton | Music is Art - Audio is Engineering |

I have a pair of speakers that support bi-wiring and bi-amping. I only have one aplifier. Will I appreciate any improvements in sound by bi-wiring alone? If you run bi-wiring in your situation you will be bypassing the crossover circuitry in your speaker cabinet, thus asking the individual drivers (woofer and tweeter) to try to reproduce frequencies for which they were not designed. Even if this causes no physical damage it can only make the sound worse, otherwise the speaker manufacturer wouldn't have gone to the extra expense of including a crossover in the first place. Bi-amping assumes that you'll be using an "active" crossover to divide up the signal into low and high frequencies ahead of amplification and then giving each frequency band its own amp and driver. It also assumes that you already have the knowledge and experience to select and setup the proper equipment necessary to do so. You aren't there yet or you'd already know the answer to your question, which, of course, already knowing the answer to, you wouldn't have asked in the first place :-) Of course if you're planning on running these speakers in a large room (auditorium, sanctuary, nightclub, etc. AND you have more money to throw at the problem, you might want to consider going with an active crossover and another (stereo) amp, but consult a good sound contractor before you rush out and spend. |
