A 270 watt speaker system with 6.5 inch drivers. It delivers great sound thanks to several technologies. The driver cones are made with Plus One technology with carbon fiber added, which enhances the bass frequencies. The tweeter domes are large, for increased power and smooth clean treble. Two-level tweeter volume control compensates for less than ideal cabin acoustics and is customizable to personal preference. Low impedance of 3 ohms improves handling of thin wires in the car and efficiently utilizes the power of the amplifier.
