Features
The MR SLIM series was designed as PRO Audio On Wheels solution for shallow doors, featuring an Aluminum Phase Plug (Bullet). This mid is built like a professional midrange loudspeaker, but it has been designed for use in the mobile audio market, as we called it Pro Audio On Wheels®!
By combining elements from PRO Audio and Car Audio we have developed a NEW type of high efficient midrange that is able to give high levels of output from stock speaker location in your car.

- Slim Design – Perfect for door stock location
- Sound Quality without Cutting up interior Panels
- Endurance at Loudest Volumes
- Vented Air pole piece for heat dissipation
- Center phase plug for even sound distribution
- 4 Ohms Impedance
- Also available in 8″- 8MR400B-4 SLIM

The “bullet” phase plug is made from pure aluminum acting as a radiator cooling system for the voice coil and machined to perfection for even sound dissipation. Beyond good looks, this cone is extremely light, providing excellent damping to keep an incredibly natural yet accurate sound.
Also featuring a cloth M-roll surround helping resonance to be kept under control making for an easy transition to a super tweeter.

The suspension design of this midrange features the single layer spider – which connects to the coil former with premium stitched lead wires, all being driven by a copper-clad aluminum wire voice coil providing high efficiency and excellent power handling.
You can expect outstanding sound stage quality and realistic sound reproduction for a great value.

Great sound elven after my tweeter blew
Awesome
Literally The Best Speakers I’ve Ever purchased… SO LOUD, SO CLEAR, SO CLEAN!
10 Stars hands down the best. I will be ordering more for my son and daughter trucks..
I love them very loud just wish there was more you could do for someone that is pushing your products in motorcycles I do the sound compactions and I have not seen any other person running prv speakers or amps but me and I get asked every time I’m out what in the world am I running so yes it would be nice even shirts and stuff to give away and the shows I fished the pro tour for 26 years and sold millions of my sponsors products and gave away stuff it was amazing something to think about
This little speaker is loud and clear. It’s slim design allows it to
Fit in tight places. Set your high pass crossover about 120hz – 160hz and enjoy loud, full,clear mid range.
I have always ran ds18 loudspeakers in my trucks but i wanted to try something else and let me tell you these prv 6.5s are like a night and day difference. LOUD AND CLEAR. I have only 2 ran at the moment to a stinger mt1000.5 amd you can hear me almost a mile down the road.
I’m impressed with the sound quality even without an amp. Can wait to put it to its capability with an amp. Being a Brazilian my self. Proud of this great product.
This speaker is really loud and good for vocals definitely satisfied with it.
Very nice great sound very heavy hood speaker
W speakers very loud and clear 100% worth the money
