PRV AUDIO 4 Inch Midrange Speaker 4MR60-4, 60 Watts Program Power, 4 Ohm, 30 Watts RMS Power Pro Audio Loudspeaker (Single)

These PRV 4-inch speakers are perfect plug-and-play replacements for the Positive Grid Spark 40 v1. The amp rattle is gone; there is still a sizeable amount of bass, but you can dial that out and stuff the voids with an old T-shirt, which helps tremendously. The bass response in these speakers is much tighter but still prominent; however, it is much more usable.

Like many others with Broncos, I replaced my center channel dash speaker with this. It's very, very loud compared to stock speakers, and fits as it should. Sound quality was much improved over the stock paper cone. This almost overpowered the others in the B&O system though. Still, a great improvement for the Bronco's stock stereo.

Very respectable speakers, especially for the money. Balanced, dynamic sound, and solid build quality. Unless you’re hooking these up to a really cheap or really expensive amplifier, these should be a great choice for most situations.

Bought to replace a dash mounted center channel speaker that had blown in my 7 series with the Top HiFi Logic 7 stereo. I had read reviews that praised it for that role in Range Rover systems, and there aren't very many options for 4" that are not sold as a pair or coaxial.The packaging is was as basic as it comes with the driver being in a plastic bag inside of a thin box that had come apart, not a huge deal but you should be careful about how you store them pre-install. The build quality is impressive for a $25 speaker especially in the wish/alibaba era. I like the look of the woven glass cone and the speaker seems to be equally well crafted next to the HK it is replacing. And while the basket is by no means flimsy, I am a fan of how easy I was able to trim the mounting tabs with some heavy duty scissors in order to fit them into a homemade adapter to go with the standard BMW 3 screw triangle pattern.I had already replaced my front door 4"s with Blam components and worried how the PRV would blend with them, considering they cost over 4 times as much if you broke it down to a per speaker price. So far I can say that I am impressed with the PRVs performance and look forward to hearing how it does once the suspension loosens up a little. My only issue so far and not any fault of the PRV speaker, is that despite having almost double the impedance of the Blam drivers, the higher sensitivity of the PRV driver is resulting in my center channel overpowering the FL/FR channels and thus throwing off the overall sound of the Logic 7 system. That being said, for the price I was willing to order another one, and will swap the PRVs into my doors and see how things sound with one of the Blam mids taking over center channel duties and will update or review the second purchase once that is completed.

I replaced the factory speakers in my positive grid spark 40 with these. Much better sound, and no more speaker buzz. These speakers are 4 ounces heavier than the stock speakers in the spark 40. I am very pleased with the sound they produce. Loud and clear, easy upgrade, plug and play. Recommended.

These speakers sound fantastic. I had tried Kenwood speakers in the same size and they sounded terrible. I'm so glad I returned them and tried these.

These sound so clear and have high sensitivity so they play significantly louder than the factory speakers. These midranges really shine when you give them a good amount of power which i have an aftermarket Bavsound amp on my BMW. Absolutely 0 distortion, they sound so good they are outshining my factory tweeters (in terms of distortion) so now i have to upgrade those! I used these speakers for my 2013 7 series BMW which are known to have factory audio problems. I purchased 3 speakers in total, 1 for each front door and one for center channel on dash and they fit perfectly which i was concerned about considering how large the magnet is but no issues!

They didn't have the sound I was looking for.
