Harman Kardon Premium System
$875 option, 360 watts, 12 speakers incl. two subwoofers (under front seats)
Spectral: Bass overpowers all other frequencies at neutral setting. Had to turn it down, and system only offered treble/bass adjustment.
Spatial: System claims to offer surround sound, but there is no adjustment for it, and we had difficulty placing specific instruments or vocals. Seemed like a closed stage.
Dynamics: Powerful, crisp sound at high volume with no distortion.
Integrity: No trim or panel vibration detected.
Overall impression: More difficult to justify the premium price of this system, which we ranked third in sound quality.
