When using my current vizio 5.1 soundbar, i hear crackling/pops/stutters from the wireless sub+speakers. will i face the same issue with this system?

I've been having the same issue with my Nakamichi 9.2 not the one with E-Arc. I've upgraded my speaker wires from the factory ones. I'm using 4k and a 8k HDMI cables gold plated. I've even had my sound bar swapped out to an updated one with vents in the area of the HDMI ports. Because they thought it may have been heat related. I'm still having that issue with all that being done. The dedicated frequency may help some. It was explained to me by the head Nakamichi ninja (lol). If you live in an apartment building you will experience interference because of all of the residents Internet signals running throughout the building. So after all of upgrades and the replacement sound bar, I still experience this issue from time to time. So if you're living in an apartment building expect to have this issue...

How is each speaker powered?

The powered subs plug into wall outlets and the speakers plug into the subs. There are wires going from each subwoofer to 2 speakers.

I have the ultra 9.2 sse, is it worth upgrading to the ultra 9.2 earc model?

Besides eARC and aptX HD, the Shockwafe Ultra 9.2 eARC system is fully upgraded: Software + all speaker drivers + amplifiers. The surround, bass and theater performance is unmatched by any sound system by a wide margin. See full comparison of Shockwafe models here: https://www.nakamichi-usa.com/shockwafe-soundbar-series-specifications

I have an earc tv, is the shockwafe sse soundbar compatible with it?

Nakamichi Shockwafe SSE soundbars are compatible with HDMI ARC and eARC TVs and can receive Dolby Atmos from your TV’s built-in streaming apps.
