Harman Kardon and JBL will be introducing fresh meat for this spring, with the MS-8 being the first car audio tuner that was specially designed for owners themselves, since it brings together a digital audio processor with adjustment controls and headphone monitors which will help tune a car’s existing speaker system. Included is a step-by-step process that theoretically improves bass, dynamics, frequency response and other factors in a mere 10 minutes – now how about that! Expect the MS-8 to ship this April for $799. Apart from that, there will also be a range of iPod and iPhone speaker docks, 5.1-channel surround sound kits and home theater systems. If you’re a huge fan of either label, then you might just want to wait until April before making that upgrade jump.
