The entire PS-Series boasts super-efficient, 20mm neo-titanium-dome tweeters bridge-mounted over the woofers to counter extreme vibration, and incorporates a tweeter sensitivity jumper. Designed as high-efficiency speakers for low current draw from small Powersports charging systems, the PS-Series provides quality without draining a vehicle's battery life or sacrificing high volume levels that should be heard over the roar of the road.
