Superb price/quality & value

The Polk db651s are perfect for getting articulate mids and highs in either a car of boat application.

They are equipped with a basic crossovers mounted on the speaker terminals (6db slope) however to sound clean they will need a high pass filter at about 60-80Hz for eliminate the lowest frequencies which will otherwise distort the sound.

Time will tell how long they will last in harsh environments like marine use but thus far (6 months) they seem to be holding up.

For automobiles the 6.5" coaxials will produce more low end such as midbass because of cabin gain however on a boat or any other open air vehicle (golfcart, jeep, ATV...) they will require a subwoofer to augment the missing low frequencies.

Once set up correctly they will sound surprisingly good with very detailed and smooth output.

For the price the value is highly recommended!

Very good sounding speakers

I purchased these speakers to replace the old completely worn out speakers in my Chevy truck. I had to modify the stock speaker mounts to fit them but they fit in there nicely now. The sound is really good. Sounds better than it ever did before. They are a good value for the price. I recommend them.

Great Value, Fast Delivery

I ordered these speakers for my 16 year old son's 1995 Chevy S-10 pickup truck for Christmas. Not only were they shipped right away, but the sound is far superior to the factory speakers at a fraction of the price!

Very good value

Very good, clear sounding speaker, and this price was excellent. I bought them for an unusual application - replacing the 4" speaker in a Roland MicroCube guitar amplifier. It gave me exactly the improvement I wanted.

Recommend!

I have these in my sound (roll) bar in my 2014 Wrangler. They sound really well with the JVC deck I installed and were even better when pushed with an Alpine amp (KTP-445U). Install was easy and I couldn't have asked for a better speaker. Easy to install.

If you own a wrangler, I would seriously recommend these. Another piece of advice is poly fill the sound bar. It does help out with the overall sound.

Big sound outy of small speakers

When you buy small speakers (because thats is all the room you have to install in) you really don't expect to get much bass sound out of them.
Well, I was very surprised at the great all around sound I got out of these Polk db 651s speakers. I put them in a smart car and they sounded way better then I ever thought they would.
For the price, they can't be beat!!

Great Speakers

I've tried other brands at similar prices, but for the money nothing beats Polk Audio (especially when paired with a pioneer head unit). This model is the shallow mount as opposed to the regular DB651.

If you can fit the DB651 instead of the DB651s, go with the non-s model. It has a slightly bigger magnet and will give you a better low end response.

All in all, Polk makes some great speakers. When I bought these from Sonic they were priced at about $65 /pair which is a helluva deal for these speakers.

Polk Audio db651s speakers

I love these speakers. I installed them in my 2000 Toyota Avalon and they sound absolutely great! I already had the JBL system in my car and the speakers were getting old so I upgraded to these and couldn't be happier. Thanks Sonic Electronix for a great price on some great speakers.
