System uses top end Sinister 6.5" neodymium driver with 1.5" voice coil. 94db 1 w/1 m woofers. When others claim better, they are usually talking about the tweeter. 1" soft dome tweeters with partial horn. Includes woofers, tweeters, tweeter bridges, speaker covers, crossovers, speaker wire, ports, and templates. It does not take a large amplifier to make Sinister Sound systems sound good, and loud. Our systems sound great with small class D amplifiers. You do not have a large charging system or large battery on your motorcycle, so this is important. Amplifier not included.Click here
