  • Summary: Sonic excellence! Down right beautiful work of art design!These are the championship series! Awesome build quality, very heavy! Nice deep, full,accurate true bass, sound quality better than most "8"subs on the market! Tweeters are sweet and not bright. Polk outdid themselves with these speakers! You will not want to leave your vehicle!If you can find them buy them without hesitation! Did I mention they have a three year warranty!

  • Summary: This is my 3rd pair of Polk MOMO's. I have purchased the 6 1/2 round MOMO's before. These speakers are AWSOME. I have them in my boat with a 2000 watt amp. They are as crisp and clear as any speaker I have heard, and don't distort even with heavy bass and volume. I hose them down while washing out the boat and it doesn't effect them at all. My next purchase will be a 12" MOMO sub.
