Our take on the Infinity 6912M

by Buck Pomerantz

Infinity's marine speakers bring superior sound to your boat. Strong, weather-resistant materials and precise construction ensure these high-performance speakers will keep the party going for years to come.

The Infinity 6912M 6"x9" speakers feature a polypropylene woofer cone bonded to a tough, UV-resistant rubber surround. This design delivers full bass response, while maintaining excellent resistance to sunlight and moisture. The corrosion-proof, cast-polymer basket shrugs off deterioration caused by salt, moisture, and UV rays, while the stylish non-removable grille is specially treated to retain its shiny chrome finish.

The grille-mounted 1-1/4" tweeter offers excellent high-frequency projection. Infinity seals the front of the woofer cone along with the speaker's magnet structure for extra protection against moisture. Stainless steel mounting hardware is included.

I purchased two sets of these 6x9 speakers for my pontoon boat and I am amazed at the sound quality. I have them hooked up to a Kenwood marine BT head unit along with a Kenwood marine 400w amplifier. I was going to install a sub along with these,but I may just leave it how it is. The bass that these speakers produce is already enough to rattle the panels in some places on the boat. The sound is clear and has a nice punch without distortion. They have a very nice look to them as well. Overall, I am very pleased with the performance, appearance, ease of install, and product quality of these speakers.
Great sound, look, and quality for the price.

Great speakers! I installed 2 on my pontoon boat. Loved them so much I added 2 more. The cutouts in the shipping box worked great for templates.
Great sound and price.
I would of preferred a white grill, but they still look good.

Very nice speakers. Look great and sound great.
Look great and sound great. No problem so far.
Didn't have a template for mounting on the boat. I could have used that in order to cut and drill when mounting the speakers.
