Hi Guys,
Regarding bi-amping, I have an idea, and I wonder of your opinion. I have a Monitor Audio Bronze 6 speaker with integrated passive filter (crossover frequency is 2.5k). I think the main advantage of bi-amping is not to amplify the whole spectrum reducing the intermodulate distorsion with this method. But for this advantage you need an active filter before the amps to split the spectrum otherwise both amplifier will amplify the whole spectrum eliminating this advantage.
On the other side I do not want to remove the passive filters from the speakers, because they were to expensive to destroy them.
And I also do not know the exact characteristic of the passive filters to be able to reproduce them on active way.
So my idea: Leave the filters (with 2.5k crossover frequency) in the speakers and use active filters too with the following characteristics:
- LF: Low pass filter with break point frequency at about 4kHz
- HF: High pass filter with break point frequency at about 1kHz
With this method the characteristic of the passive filter will prevail, but the spectrum on both amplifiers will reduce significantly reducing the intermodulate distorsion.
What do you think about this?
