Misprint… 90db not 60.. havent installed yet but boxed well. Includes speaker wire with terminals already attached to wire. Adjustable tweeters. They are 3 ohm…Installed 4 of them on motorcycle. Not bad for a 4″ speaker. Has many things I like.. adjustable tweeter.. nice silver coating on tweeter that looks good behind my stock speaker grills. So far they are holding up well with weather. For $22 they are a good deal and are great for my application. Just as good as the 4″ Polks… The brand seems to be quality as I have a 5ch amp in my truck… good clean sound. Just as good as my Alpine and MTX of the past.
