Selected User Reviews For Polk DB652 UltraMarine Dynamic Balance Coaxial Speakers, 6.5" - Pair

This item does not come with a warranty since the serial number has been scratched out
3/5

There were no problems with the speakers, but it would be wise to register for warranties. It's apparently because they mark them out with a black marker, and when asked why, they don't say why. The number I attempted to register had already been registered, so I managed to obtain one for a low price. My opinion is that this is shady!.

The best marine grade speakers you can buy
5/5

There are two pairs on my bike, one in the fairing and another in the lower section. They are exposed to rain in the lower part of the house and they have never caused me any issues. I use a small Kenwood amp (kac-26) to power them. They have a great sound (m1824bt) and The sound of them over my pipes and highway speeds of 75 mph can be heard. People who ask me for recommendations should try these.

This is the best six
5/5

I never heard anything like this before. HOLY CRAP is all I have to As part of my 2009 GMC Sierra 1500, I replaced my factory speakers with a factory head unit. My back door is where I placed these. With the head unit equalizer, I think the bass is best emphasized on the back, so I chose fosgates for the front and these for the back. It is amazing how good these speakers are for not having an amp. Some complain that there is no bass in these because they want bass like a subwoofer. The expectations you have for amp free 6 are unrealistic. Speakers with a diameter of 5 inches. NOW IS THE TIME TO BUY.

It would be beneficial to upgrade the motorcycle application by adding an amplifier
4/5

They fit my 2015 HD Road Glide nicely. Unfortunately, they were a little tricky to align the factory holes and speaker mounts, but we got them there in the end. It would be beneficial to upgrade the motorcycle application by adding an amplifier.

To a very good volume, they play as clear as a bell
4/5

Despite this, however. On my boat I am using 100 watt rms (a clean JL Audio amp) as filler speakers between two sets of Pioneer 8's and a 12 sub, so I have turned the gain down a little To a very good volume, they play as clear as a bell. In addition, they are harsh until you tune them and tame them, and even then are a bit harsh, so EQ is necessary to pull out some of the mids and reduce the harshness While I have only used it for 20 minutes during the tune, it is definitely worth it for the price. I like the purchase. Our boat trip will help us determine whether they hold up.

I like the sound quality a lot
5/5

It is my second pair of these Polk 652s. Access cab for a 2004 tundra. The stock tweeters are in my front doors, but I have these in all 4 of The sound is really superb. Despite the uneven distribution of lows and highs, the overall balance is very good. My speaker budget has grown over the years, and I have replaced a lot of speakers with high Among the companies we already mention are Klik, Romford Fallsgate, Kicker, and Sony. This is the best sound quality I've ever heard on my car without using insulation, moving a sub, or modifying the stereo settings to suit my taste. No matter whether you have a stock or not vehicle, these sound great. When you buy these, every penny you spend is worth it.

Polk speakers are always a good pick! The two things are a perfect match when they're mounted to marine-grade plywood panels in the Weldcraft boat and powered by a Planet Audio PGR35B head unit
4/5

In addition, it definitely helps to have the front bow area enclosed when mounting the speakers. The bass is more than sufficient for a fishing boat, the mids and highs are clean without being overdriven, they're not muddy or lacking in volume, and the volume is loud enough to jam out if we so desired! In a boat with a 150hp Merc jet, the audio can be difficult to hear over the engine's insanely loud noise, but at lower rpm, the sound is very good and heard Last time I owned a boat I went cheap on speakers and had some poor Boss 6112" speakers. This time around I have some nice ones instead! I think these are a good pair of speakers, better than the Boss speakers I had on the old boat that cost 20 dollars each.

The quality of Polk speakers is excellent
5/5

In my boat, I replaced old Clarion speakers with these Polks. Having your music 3 times as powerful and very clear, crisp to jam to on the water is now possible. A lot of research was done before deciding on these marine speakers. The brand I have been using for the past few years is Polk, which is known for its high quality speakers. This is a great deal for speakers that sound great!.
