If that’s correct, wouldnt that be a relief for the that amp?Yes as it only sees the load of the tweeter and it's xover
Same for the bass amp

Do I need bi amping?
Ok. I think I will try it that way. The only caveat is that the Concept 500 have the crossover at 2.5 khz so I will have the Class D amp runing a good part of the mid frequencies, maybe loosing some good 300B midrange smoothness. We’ll see. I think even if I had a crossover between my preamp and both amps, to split the frequencies below the speakers crossover point, I still would be limited to their 2.5 khz. So I believe there's no point on buying a specific crossover. |
I think your ok class-d to many only seems to have problems in the highs, I believe it’s because of the class-d’s output filters HF phase shift. Red trace. https://ibb.co/C16rpXx Cheers George |
Ok. I will try to see the result. But how an external active crossover will be revelatory if the internal speakers crossover is a limitation? I mean, if I only have one (1) pair of speakers, how do I biamp them using a different crossover point than the one they already have from factory? If the answer is bypasing their internal crossover, it’s outside my reach, knowledge, patience, money and will. Besides, one the best thing the Concept 500 have is their internal crossover. The blend between drivers is very very good. Another option is to use an external crossover to split the signal before the speakers, setting a crossover point between the speakers and the subs, but that would mean four things: 1- To split an amplified signal, wich I believe it’s not ideal. 2- The subwoofers shouldn’t reach more than 100 hz or their perfomance will be poor. 3- Maybe it wouldn’t be much relief for the valve amp if it only avoids amplifying the frequencies from say 100 hz and below. 4- I’ve setted up the main speakers and subs in my room considering room modes cancellation in bass frequencies. If I add an external active crossover between them, modifying their bass outputs, I may have new bass problems in the room. |
