Fully differential Amp and speaker crossover
« on: 2 Aug 2018, 01:31 am »
Hi Guys I have a question for an expert crossover designer! If you have a fully differential amp like the Pass Labs XA60.8 where the Neg.(-) actually have signal! does that means that you have to put the same value of caps on both poles on the speaker. My speakers only have 1 cap on the tweeter a 10UF on the + leg nothing on the Neg. but my logic tells me full signal is reaching the tweeter on the neg leg because there is no cap in the neg leg.

Does this means that I need to add the same cap to the Neg(-) so confused ????

No, most loudspeakers are two terminal systems. There is no reference to an external ground. So no external asymmetry is involved.
