EXCELLENT CHOICE

These are excellent replacement speakers for motorcycle fairings. I run with straight pipes with no baffles and have no problems hearing these speakers. The looks are great I have won many 1st place trophy's at bike shows with these speakers in fairing, I have also purchased another pair for my second bike, they also hold up to water excellently, been through rain even had water sprayed directly into them ( Bike Show, Bike Wash, Blond Girl, need I say more?) and they still work great. BEST SPEAKER FOR THE PRICE!!!!

Good speakers for the money

I updated the speakers on my deck boat. They are a good set of speakers for the money. However, I put a set of JL audios on the front of the boat and no comparison. Of course, the JL's were also 3 times the cost and needed more power to produce the sound. If good sound for cheap is the way you are looking I would highly recommend. If you like cranking the volume up then maybe you might go with a higher quality speaker that can handle more power. Overall i would say 4 out of 5 stars.

Great Speakers!!

I bought these to mount as a center channel setup in my 1986 Chevrolet Crew Cab's original 4x10 dash slot. It took some modifications and building a custom plate for them, but they fit better and sound better than a single 4x10, which I tried before ordering these. They work great and I achieved what I was looking for.

SOME OF THE BEST SPEAKERS I'VE EVER HEARD

I put these speakers in my Harley Road King faring and even my mechanic said they sound better than HD stock speakers. I would recommend these speakers very highly.

good

I have 2 of these in the front. They are very good at picking up high sounds and very clear. Not good if you want to crank it up with bass though obviously since its a 4 incher. Not bad for 4 inchers certainly.
