The placement and angle of every speaker and the careful consideration of every component were essential in the development of the Lexus Premium Audio System in the IS F. And for the true audiophile, an available 14-speaker Mark Levinson® Premium Surround Sound Audio System  uses 5.1-channel architecture and pushes 300 watts of power, immersing the entire cabin in sound quality that was once only reserved for six-figure home audio systems.
