Priced Per Pair
Important Note: Polk Audio specifies the nominal impedance of these speakers to be 2.7 ohm. The product box states the impedance to be 4 ohm and the speaker magnet shows 2 ohm, this has been confirmed by Polk Audio to be an incorrect specification. The product manual is correct in stating the nominal impedance of the MM series of speakers to be 2.7 ohm.

talk about bang for your buck
hesitant at first but once i put them next to my type x pros i was relieved. Not only can the keep up but they can outdo them and the price is definitely a nice perk too.

I think I'm gonna need a bigger AMP
Replaced 2 Sony Xplod with these and wow what a difference.. these Monsters hits hard.. Now I get a nice clean mid bass and the highs are very clear..
I have a Clarion EQ hooked up to my Pioneer gm6400 just for the 6x9 and I had to turn all the levels back to 0. Unfortunately my amp is only 75w rms at 2ohms x 4 (2channels bridged for a 10" sub) so I have to upgrade my Amp since I cant crank up the volume..My rear deck now rattles so it now its also a Dynamat project..
These speakers brought out things I have not experienced before with my Sonys good and bad ;)
Definitely recommend these speakers to anyone but be aware the thin metal on the rear deck will shake so please use sound deadening material.
By the way C********** stated these won't fit my 07 Altima but the DB691 would.
Maybe because these are rated at 2.7 ohms? But they fit perfectly no mods, brackets etc just can't use the Polk grills..

not bad.
These speaker's aren't to bad, I think my jl audio speakers that I had previous to these mm's sound better at extreme volume.

Great Clarity
Great speakers that allow you to crank it up inside without blasting out the neighbors. You can definitely hear me coming but you don't hear the annoying rattling that most speakers generate. These speakers are with out a doubt the best bang for the buck!

great product , amazing price
I am very satisfied with the product. The sound quality compared to my old marine speakers is a huge difference. The system has sound filtration so the sound can not be more clear. overall it is a great product for marine use.

Polk Audio MM691
These sound great in the back deck of my new Challenger! The high's and mid's can handle a lot of Power from my Kicker 350.4 amp,and they still have clarity!

They slam killer base
I have a old school rockford punch 250.2 amp and a alpine 103BT head unit I set the cross over to high pass 80hzs and these speakers slam with killer base I'm so very happy with this buy.I acutualy cut my doors to make theys fit behind the door panels so know one could tell what I was running they trip on how loud and how hard they punch I highly recommed these speakers and I bought them because of these reviews there so right. I thank you Sonic reviews.
