Smooth upper register, incredible bass response, excellent value
By Joel Grant
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 put a set of 4 of these in my wifes aveo a year ago and they are still alive and pounding just as crisp as ever, I just bought a set of 6.5s and 6x9s for my s10 blazer and they are also amazing quality they look great have 9.5/10 lows 10/10 mids and highs you will be nothing but pleased. They come with foam gaskets that are really nice makes alot better seal, adapter rings to fit to a variation of vehicles, mounting hardware, and a really nice set of grilles. Buy them dont look at anything else just buy these lol. You wont get better for the price Ive heard some really really high end 150$ a pair type speakers that were slightly better but not by far.

Great speakers
By N. Ward
I really love these speakers. They produce wonderful sound and bass, even without an amplifier. I only have one complaint. I did a lot of research and cross referenced multiple websites before buying these. All sites said these would fit my car (2007 Chevy Cobalt). The speaker did fit in the housing, but the mount where you screw the speaker into the housing was too thick. It only allowed me to use two of the four screws. I had to do more research and find a way to secure these without those other two screws as I do not have the tools to widen the screw holes.
