Anyone have more specifics on the Audio system. I like the 360 surround idea and removable speaker, but wonder about specifics -- any amplifier, sub-woofer, or etc. They called out the titanium dome speakers, but not sure on rest. Also, is there any plan for a cover underneath the glass, for example, if someone wants it much darker inside... they can close it? Was def. looking for the 400+ miles and excited to see how close they could get to the 350kw charge rates, but guess that will come with time.
