Product Details

PRV Audio 6MR300SEAL 6-1/2" Sealed Back Midbass Midrange Woofer 8 Ohm

A sealed-back basket design on PRV Audio's 6MB300SEAL 6-1/2" midbass/midrange woofer protects it from the air swept by larger drivers in a shared cabinet. This results in decreased driver distortion, increased durability, and increased midbass punch from 250 to 500 Hz and power handling over the open-back 6MB200.

A thick, yet light and rigid paper cone, 1.5" voice coil, durable spider suspension, and a woven surround supported by a sturdy steel basket. All of this ensures its ability to withstand long hours of operation making this driver a popular speaker choice amongst high output car audio enthusiasts, especially when you consider the extra moisture protection offered by the sealed-back design.

Rated 5 out of 5 by from Accurate specs; very loud!After testing these midranges, I found that the 1-watt SPL, frequency response, and the RMS wattage rating are all accurate. The sound quality is excellent, even with the most demanding computer-generated music, which is why I'm giving this midrange five stars.The only problem I had was that part of the basket (as seen in the attached photo) was bent when I took it out of the box. I didn't feel like exchanging the driver, so I just used a hammer to straighten it out, which worked out very well.So what is this driver capable of? If you use a first-order high-pass filter at roughly 1000 hertz, then you'll be able to produce sound pressure levels high enough for a high school dance in a full-sized gymnasium, but nothing larger than that.

Rated 5 out of 5 by from Decent sealed midI used these to replace some Dayton RS52AN-8's that met an unfortunate demise as I was putting together my new active crossover setup. Couldn't be happier that I made that mistake now that they're installed. The midrange is much fuller with a good spl match to my other components and I have more flexibility with the crossover points. I'm still waiting on a couple more items and will be measuring response with the new Dayton EMM-6 Mic I picked up recently to EQ the speakers and room with my miniDSP2x8 xo.There weren't many reviews for these speakers when I purchased them but the specs matched my needs quite well and using sealed back units again made the process of replacement easy - not needing to seal off another part of the enclosure for a mid driver of this size. Nice construction and the workmanship seems good.I don't know about the rest of PRV's line but if the specs match your needs I wouldn't hesitate on recommending this one.

PRV Audio 6MR300SEAL 6-1/2" Sealed Back Midbass Midrange Woofer 8 Ohm

Is this a 6" or a 6.5" driver?

Asked by: AndrewT
This is a 6-1/2" driver.
Answered by: MattP
Date published: 2015-02-20

Just to make certain ... because this speaker is sealed, it doesn't need an enclosure or ports or any of that other stuff. Just mount it and you're good to go. Right?

Asked by: Chronic Iguana
Yes that is correct.

Is there an impedence plot available for this driver? Wanting to work on the crossover.  Thanks!!

Asked by: GWally

What size of hole do I need to cut to fit it I'm properly

Asked by: Timbo111
Thank you for your interest in PRV Audio products. I have verified that the cutout of 5.82" listed on the specifications sheet (listed under Manuals/Resources) and on the Mounting Information (listed under Product Details) is correct if front mounted onto a baffle.Some customers choose to rear mount this speaker. If that is what you would like to do, please cut a 5-15/16" hole (5.9375").
