Customer Reviews

I own multiple sets of polk db and infinity reference series speakers. These are tightly competing product lines both offering incredible performance and value. This is my first set of 6x9 by either brand, so I can't compare them directly, but here are my comments. These were installed into the rear deck of an older bmw and replaced 6" woofers/1" silk tweeters. They are driven by an old school 65x4 RMS clarion pro audio amp (back when clarion was better quality). I intended the polks to provide good bass to complement a set of 5.25 infinity reference components in the front. They surpassed my expectations.
Pros:
- Fantastic bass response. No question. I have the amplifier network boosting the rear channel by ~6db at 40hz, and many have asked if I have a subwoofer because the low-end extension is clean and can be felt through every seat in the car. Dialed in properly, these perform very well to 35hz in tightly sealed infinity baffle (trunk/cabin) setup. These can literally make my very-tightly adjusted trunk vibrate more than my 100 watt rms 8" subwoofer due to the infinite baffle setup.
- Highs are clear, but have a warmer tone.
- True 4 ohm speakers are easy on amps and unlikely to cause create any clipping conditions
- Awesome power handling. IF YOU PAIR THESE TO A HEAD UNIT DIRECTLY, YOU WILL BE DISAPPOINTED. There is simply no way a head unit can cleanly drive these large speakers if you want to hear them as they were intended by the designer.
Cons:
- Simple integrated crossover does not deliver the clarity of component setups, but it does very well for coaxials
- Speaker cones are quite thin and flexible, probably do not deliver as accurate of base as they could otherwise (though the bass is extremely impressive)
- Mounting hardware is cheap and flimsy, Polk could have spent a few more cents on decent screws, nuts, etc.
- Slightly less performance/quality for the money than other brands. Infinity give you better overall value in my opinion with their reference series.

I decided to upgrade my sound on the interior. my choices came down down to infinity and polk audio. and i honestly chose the polks because the infinity tweeters looked ugly and i knew the sound quality between them was similar. I am very happy with the sound out of the polk they sound awsome. I do have them running through an amplifier and they do need the power to push them. with this upgrade id be happy even if i didnt have a sub. which i do but i turn off quite often when i feel like it and these speakers sound amazing.
