Probably wireless with built in amplification, and perhaps room correction. But it must sound as good as any planar/ribbon/dynamic speaker.
I want my speaker sounds like the original music. I am getting close.
If the original music (cleanest) sounds veiled and fuzzy, your ears are unnatural hearing mode. To make your ears to normal natural sound mode, listen to the original music for 1-2 minutes ("equalize your ears to make ears to pop to make it faster) until the orig music sounds clean.
General public (non-audiophiles) ears are always in natural hearing mode. So, they hear all hi-fi audio sound veiled and fuzzy. Therefore, wives don't like hi-fi audio sounds. All audio systems (except my WT system) in the world sound unnatural. Alex/Wavetouch
