Nice n thumpy

Very high sensitivity and thumpy lower mids. Cutout is big - like 4 7/8 and the basket on these things is WAY deep. Not a shallow speaker. Good value for rear deck.

Great Company and Speakers

For the price these speakers sound just as good as speakers twice their price. One mustn't forget that these are JBL speakers. JBL's are still being used in recording studios, theater, and for announcing. Remember studio monitors.....wish I had gotten a pair. Tried to, but couldn't pull it off. Anyway, for the money, you cant go wrong.
