Priced Per Pair

Note: Polk Audio specifies the nominal impedance of these speakers to be 2.7 ohms. The product box states the impedance to be 4 ohms and the speaker magnet shows 2 ohms, 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 ohms.

Speakers sounded great, and had a lot of power, but the durability wasn't as good as I expected. To get the right sound, you need an amplifier or it will just sound all crackly.

I replaced my damaged Rockford Fosgate Power Series 6x8s with these just to try somethin new. I just put these in, so they need break in time still. Compared to the RFs they both have pros and cons, these are very clear sounding, but not quite the low end response I'd hoped. When they break in I'm sure they'll be fine. I have them powered by a Memphis M Class that does 50x4 at 4 70x4 at 2 so they're getting good power, Kenwood X993 HU. I recommend these if you want high SQ. They have nice crossovers as well.

These speakers kick out a ton of midbass for a 5 x 7. They actually make my doors rattle. The highs are crisp and detailed without being harsh. The only drawback is that they have seperate external crossovers although better they are a pain to mount in tight spaces. Also you have to remember that these are 90 watt speakers so you need an amp to make them sound good. Don't just hook them up to your head unit and wonder why there's no bass.

I purchased these a few weeks back and have never been so aware of the varying tones embedded within the music I listen too until now. The clarity is astounding and the ability of these speakers to handle such a huge wattage is supreme. I cannot wait to get another set to complete the setup.

I have a F150(single cab), and still have room for 2 more. Although I'm using the crossover as provided with these I have yet to detemine whether I should keep the amp filter on full or hpf, either way they sound great( these are running off a Crunch 500.2 amp).

Will purchase more of these from Sonic in the future, thanks fellas.....

Not so sure about these speakers. IMO they have a very week mid range and very little bass response. The speaker wire clips have come loose twice not only on my vehicle but my friend has the same speakers and his wires came off as well.

Richard M.,
Not only did you provide an answer to my question quickly, but you went up and beyond your call of duty by informing me of other parts I will need in order to install my new head unit. Thank you so much for your help and expertise.
