installed 2 of those in chevy sierra 1500 extended under rear seat matched with kicker zx750.1 under 2 ohm load and while i normaly don't waste my time reviewing anything ----- those 2 deserve review enought for me to actualy sit down and type (i hate TYPING)

dont get me wrong they are NOT as good as SR series (no longer manufactured) but not very far behind ----- they handle anything from rap to rock right through some of the heaviest base hitting electronic !
you set your amp gain and eq right and you can and will switch betwen music genere without touching any controls in your head unit or adjusting eq (some older ROCK might require a little base boost)

if you are looking for SQ with some awesome pressure look no further they are not going to win against DD's or other 75 lb monstrocity designed for nothing but monster pressure under very narrow frequency band!!!

but any main stream (good Brand SUB) is going to have to work extra HARD to hold their own against MM series and it's a losing battle

i've compared them to several others and no JL, RF, RA, KICKER, MA is comming close to versatility of sound being reproduced (some get slightly louder but at much higher price bracket)

the recesed magnet is an awesome idea !!

dont forget your poly fill (10-20 oz. bag pet chamber) and take POLK.s advide and make your Bafle 1" thick MDF your ears will apreciate this very much and so will your amp !!!

P.S. i've tried those 2 powered by Hifonics Brutus BRZ-1200.1D and the efect was just as astounding !!!!!! and just my observation is the those subs do better in wel designed sealed enclosure of at least .7 to 1.2 cu ft per chamber ! - although i've installed a single mm 1240 under HIFONICS BRZ 1200.1D in sealed .62 cu ft (in my 2012 Toyota Yaris) in 4 ohm configuration with amp mounted upside down above my doughnut spare and absolutely love the result The sub POUNDS very hard and amp under 4 OHM load NEVER gets warm on normal weather and warm to touch durring the summer on the hotest of days !!!!


hope this helps some of you in making the decision to moove towards one of the best speaker out there from a manufacturer who is bent on SQ since they started in AUDIO !!!!!

I was using 2 jbl gt5 s12 sub's in my toyota innova, read about this sub on various sites believe me it deserves 5 star rating. It can out perform my 2 jbl subs with a ease, it sounds clean and can go very deep even with sealed enclosure. It is a only sub that can perform good with less power. My search for the best sub is over with this sub.

I bought these about 6 months ago and boy do they sound good. I did research on many name brand subs before finally deciding on these and I am very satisfied. The price was good but nothing can beat the base sounds that they put out, not even the price. I will never get any other subs but Polk. If you want nice sounding subs go with another brand but if you want the best sounding subs then pick up a pair of Polk Audio subs. From a man that's been listenning to bass all his life, you will be happy.

I have one of these in my dodge durango running on a AP1200 Profile Amp and it hits hard and loud not to mention it also can hit bass in every range. I highly recommend this sub along with any of polk's products, thats all i have and they havent let me down whatsoever

This sub is awesome! i bought two of them and they hit hard now i am gonna have to buy Dyanamat from sonic cuz they rattle the whole car! awesome sub in my opinion!
