After I purchased Triton Ones I saw that GE stated that the passive crossovers were 'balanced.' I asked my dealer why that could possibly mean. He did not know. Now I see that the SuperCenter XXL has balanced xovers, but the other centers do not.

I know generally how inductors, capacitors, and resistors fit together to form a network to send the right frequency range to the right speaker units, sometimes shaping the frequency response. But what 'balanced' would mean escapes me.

Thanks in advance for comments.

I think there is a good explanation here:

Thanks for the video; it helped a lot.

It got me to thinking and led to some more questions to bring this down to my level:

dsp in the bass amplifier - this seems to imply that the class D amplifier controls the crossover between the bass and mid-tweeeter section. That is, low pass for the bass and high pass for the passive crossover the mids and tweeter. In addition, dsp has logic to create a smooth transition for any setting of the bass volume. Correct?

Eliminating "common ground cross coupling between transducers" seems to be analogous to splitting the passive network into two separate sections and then bi-wiring them. Correct?

As for a balanced impedance at the voice coil terminals of the drivers, is this not like what Zobels were intended to do?

thanks again.

Nope, the passive crossover is fed directly from the speaker terminals. The DSP only affects the woofer section and is responsible for the "blend" to the passive section of the speakers. And yes, the DSP insures the volume ramp up and down with the speaker's level control is smooth and does not interfere with the blend to the passive section.
