Can We Pair 4 Ohms Speakers With 6 Ohms AVR?

[doors666]

I am not sure how this can be done, but I am sure there is a way to increase the impedance of speakers without affecting other features. Since Naren likes the PSBs so much, this may be the best option.

Cheers

that would mean redesigning the crossover, at the minimum an extremely complicated task.

2) However if there is slight difference like it is in my case ( speakers min impedance 4 ohms and AVR impedance 6-16 ohms) then it may result in sound distortion at high volume and the AVR may get hot if volume is not brought down immediately also it may result in AVR getting auto shut down as a safety measure by the AVR circuit but this all may not happen if the volume is kept not very high

Sound distortion is a function of:
1. amplifier operating beyond its linear operating range, and/or
2. speaker operating beyond its linear operating range

And both depend on the volume position in the amp! So you know what not to turned up too much:lol:

Does a slight mismatch in impedance between source and load make either amp or speaker to operate beyond their linear range? or at least quicken the process? Well I don't know - I am asking. But I think not. As far as my limited understanding goes, a mismatch reduces energy transfer and that's about it.

And regarding someone pointing out that the resistance is reactive, please note that the impedance of any source and any load is never pure resistive. It will always have inductive and capacitive components. But for design and practical purpose all complex voltage sources are reduced to their equivalent simple source using Thevenin's theorem and all similar complex current sources are reduced to their equivalent simple source using Norton's theorem.

Actually in this scenario, we should not worry. However if we run a 4 ohm speaker on a minimum 8 ohm supported amp, depending on the amp's current drain capacity, you would loose this linear operating range as the current drain will always be higher beyond the DESIGNED range and hence voltage will continue to drop making the output UNSTABLE and hence will add a distortion of about 1 to 2 percent due to such unstable and non linear current and voltage curves.
