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

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.

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.

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.

Speaker arrived with damaged dome and bent corners due to a very flimsy box that broke, allowing the speaker to be knocked around in the Amazon shipping bag. I hooked it up to a Spark 40 amp to see if it still worked, to see if I wanted to try a replacement. It's sounds almost identical to the stock speaker, so if you are looking for better sound in your Spark 40,this isn't the answer. But, as a speaker for another application, it sounds fine. But the packaging is very poor.

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.

These little mid range drivers are so loud. I build speakers from ammo can and cases... I was blown away at the clarity!!!!

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.
