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

Do I need bi amping?

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. |
Maybe a dumb question, but I’m not an expert on the field. If I connect one amp to the high frequencies binding posts and one to the low frequencies binding posts of the speakers, and both amps are "feeding" a full range signal, I believe it won’t damage the speakers as their crossover is filtering the full range signal to what's needed for each specific driver. I mean, it will relieve the amps from amplifying the whole signal, but it won’t damage the speakers. Am I correct? |
