Review on Poly Planar MA 4055W 5 Inch Flush Mount Speakers by Ron Patel

I have a pair of omnidirectional speakers on my pontoon boat that have worked great for 12 years and still work great. My other speakers that came with the boat were falling apart so I ordered these polyplanar speakers to replace the faulty ones. The speaker cutout for my old speakers was 5 inches. The neckline size for her should be 4 3/4. You worked in a 5" hole, but you must center them perfectly or one of the screws will miss the mounting surface and go into the cutout. Once installed they sound and look good but then again I'm not trying to add any more waves to the water. I just want to listen to soft music and go fishing.
