ok speaker exagerated highs

I like a flat response in speakers for realistic sound. I record music and reference the mix in my car also. The high boost makes it hard to judge a mix. might be good for some people but just too bright in one high frequency for me.

Sastifying Product

I got the Polk Audio db651 6.5 in speakers. I have a Dodge Dakota Extended Cab and got 2 pairs. I am VERY impressed with the sound clarity and just sheer power of these speakers. Granted it is in a truck cab but these things are extremely loud. They have great clarity at all volume levels and are able to play loud enough to make me yell at my passengers to be heard and they still didn't have any distortion. For $65 a pair they are a steal. I'm only running 22 rms thru my head unit and they can take 60 rms I believe. I highly recommend these speakers to anyone.

kind of tinny sounding

There seems to be one high frequency that is much louder than the rest around the frequency of a hi hat or cymbal. I prefer a flat response.
These speakers have that high boost which colors the sound and doesn't sound real.

Polk Audio db651

I had replaced the Polk Audio db61 door speakers from some kenwood speakers that I ended up blowing. Believe it or not, they sound better!
And for the price you cant beat it anywhere.

GREAT

These speakers were installed in a 20 ft wakeboarding boat and without an amplifier these speakers get loud and clear with no distortion.

Major step up from stock boat speakers

Like others speaker clarity and loudness are great, bass is a little weak. I'm working on a set for my Tundra next.

Great for the price

Polk has always been a good brand. With a well adjusted stereo I can get good bass and treble as a two-way speaker is expected. The mids are alright as expected.

Four of these in my truck can provide enough thump to delay my decision on installing a sub. Everything from acoustical, rock, r&b, and whatever sound good. This is coming from an audiophile.

Incredible speakers (especially for the price)

Great speakers for an even better price. Very well built and sound phenomenal. Offer great highs, good mid, and surprising bass. They shake my truck even when they are barely cranked. I have a 98 GMC Sonoma with a JVC head unit running 18 watts RMS power and the speakers have plenty of power.

My only complaint is that installing the speakers was very difficult. The supplied mounting bracket was nowhere close to the right size for my truck so I had to re-drill mounts and use those horribly tiny mounting brackets they send you. The speakers are also much taller than stock and push on the door panels slightly. Grill did not even begin to fit.

Overall, though, I would recommend these speakers for anything from a stock head unit to a powerful aftermarket head with an amp. They are a major upgrade I should have done years ago. I plan on putting these speakers in every future car I own.
