DB402 DB+ Series 4 Inch Marine Coaxial Speakers, Black

Installed in my 2018 Lexus GX460 (non Mark Levinson and using the stock amplifier) in the dash corners and center. The installation was super easy and only required a minimum amount of fussing to get the fit right. I chose these due to the high efficiency rating knowing I’d be using them on the stock amplifier. They actually sound pretty good. Bass response (for a 4 inch speaker) as well as detail and dynamic “punch” have all improved over the stock speakers. For a budget upgrade I’m fairly happy with them.

Sounds great. Replace your paper speakers with these. You won't regret it.

Handles power well , strong can handle rain and off road , easy set up , very durable , great clarity , great compatibility with marine pods

Using these speakers as an upgrade in a Spark 40 desktop guitar amplifier. Definite improvement in balancing out the audio spectrum versus the stock speaker performance. Perfect fitment and easy to install. Includes all wiring and mounting accessories needed for a variety of applications. Familiar with Polk products for a number of years, trust their build quality and faithful musical reproduction. Pricing represents an unbeatable value - an additional positive note for choosing these. The Polk DB402 DB+ speakers are certainly another fine model of Polk's exemplary offerings!

Very easy install on 2021 Bronco to replace horrible OEM front and rear 4in. Significant upgrade in clarity but much more impact in the dash speakers than the rear speakers. These low profile coaxial speakers fit nicely and tweeters that protrude any more would not fit. Needed to add washers to screws on rear speakers since they aren’t quite as big as the OEM with the built in ring. OEM front speaker bolts have a built in flange so no mod needed.

I bought these to add to the saddle bags of my cruiser and I have nothing but great things to say. These speakers sound amazing and were incredibly easy to mount and wire. Once they were installed they make some noise. I pretty much have surround sound even when I am riding. They are strongly built and made to last. There is no cracking sounds or issues when the stereo is turned all the way up. They have a nice deep sound and the bass is clear as crystal. If you were considering buying these puppies, go ahead and get them.

Very well made. Work as they should.

Brought these speakers for motorcycle to replace factory speakers. Disappointed in bass sound as it is weak to my ears.

These speaker flap and fart even at low volumes. Tried mounting them in unsorted and ported enclosures. My original no name brand speakers are better. Was trying to get something much nicer than factory speakers. Supplier is comunicating with me to resolve my issues ATM.

Product was exactly as described, I used them for my 4 wheeler sound system and they see plenty of rain/mud. no issues in the last 2 months I've had them

The tweeter on one of the speakers isn’t working properly; the high frequencies seem to be cut off.

I thought they were great sound for the money , good mid-range and bass was good

used these to build a bluetooth speaker and the sound quality is great, definitely a good buy for the price.
