Rear Screen: 48-inch Ultra-Widescreen
The centerpiece of the 4-seater LM is a 48-inch HD monitor that spans the width of the cabin partition. It can be used as a single giant cinema screen or split into two separate 24-inch displays for independent viewing/meetings, complete with two HDMI inputs and independent Bluetooth headphone support.
Audio: 23-Speaker Mark Levinson Reference 3D
While the 7-seater gets 21 speakers, the 4-seater flagship features a 23-speaker Mark Levinson Reference 3D Surround Sound system. It is designed to turn the rear cabin into a soundproof "mobile concert hall," assisted by five layers of acoustic headlining and active noise control.
