I know that wiring two speakers in parallel to one set of speaker outputs halves the impedance the amp sees. Correct? So does biwiring a speaker have the same effect on the amp? In other words, if I biwire my 8 ohm (nominal) speakers, will the amp "see" 4 ohms? Thanks.
Not neccessarily guys. Buffered amps and throughput (Krell) amps can see a super low impedance from the high freq posts. Depends on the crossover. Do a little homework on the speakers you want to try this with if you are not under warranty.
Kal, It is quite common in first order crossovers, both the woof and tweet work far outside their sweet spot with such a gentle slope. Tweeters particularly drop impedance in this situation. Amplifier say POOF! If the amp can handle very low impedance, tweeter say POOF! Been there- done that.
Any fisrt order crossover has drivers operating over greater frequencies. Drive a tweeter at 300 cycles and report back with your findings. Blown tweeter or amplifier? A buffered or throughput amp has no connection with any part of a crossover as is "normal", so depending on how stable the amp is determines which blows/burns first. I have blown a Krell amp this way and can think of no other brand as stable at frequencies approaching DC.
After reading again the OP it seems I may have misinterpreted the question. Somewhere down the responses, anwsers got a bit off topic and I followed along. I have blown up a few things (luckily under warranty) and would not wish this on another member.
Kal, Thanks for letting me slide. Low impedance is a real issue that newbies can get into trouble with. Several speaker mfgrs refuse to replace tweeters that have been burnt by unstable amps. They claim owner abuse when it is simply a matter of "I didn't know".
