Review on Seismic Audio SA MS69W Waterproof Speakers by Johnny Spencer

First the bad. Due to the strong plastic frame on the back, the original 6x9 hole had to be cut larger. Don't take the tool needed to widen the hole. This is bad. Now for the good stuff: they sound great, the frame and lid are made of very durable hard plastic. Very high quality workmanship and not skimped on the material. in my cockpit and I put my foot on it when I swim. They are smooth with rounded edges and are great for foot support. Yes they are that strong ;) Very very happy with this purchase. if they last and sound good. Time will tell, but it looks like they're holding up.
