Product Details

PRV Audio 8MB500-NDY Neodymium 8" Midbass/Midrange Woofer 8 Ohm

PRV Audio's 8MB500-NDY neodymium 8" midbass woofer is a lighter version of the popular 8MB450 and offers the same high output punch, a smooth midrange, and response up to 4,000 Hz. A lower Qts motor design offers more driver control, and a lower free-air response allows it to reach a little bit deeper. The 8MB500 is designed for use as a midbass or midrange driver in 3-way speakers. Alternatively, you can use this speaker in small sealed and ported cabinets as a woofer in floor and studio monitors.

A thick, light, and rigid paper cone is mated to a 2" voice coil for great sensitivity and high power handling. A durable spider suspension, woven cloth surround, and stamped steel frame are combined for extreme durability. High output SPL car audio enthusiasts gravitate towards this driver for use in their systems when looking for a lightweight midrange or midbass that can sustain long hours of extreme operation.

Rated 5 out of 5 by from ABOVE EXPECTATIONSLet me start by saying this...  After first trying and loving the 6" midbass drivers, I received a call from Parts Express and was offered a free pair of PRV 8" neo-drivers.  I thought to myself PERFECT TIMING!  This began the design of a PRV 3way masterpiece at a fair price point for a build I had been planning.  The D280Ti-S, is a well built horn driver which I found works very well with "apologies to PRV" Selenium's HC23-25 Horn.  A simple -3db attenuation in the crossover build perfectly suited the horn with PRV's 8" neo-driver.  After finally coupling the PRV 15w700, PRV 8" neo and PRV D280 into a 7cu.ft. sealed enclosure crossed over at 500/2.5k, I found that my purchase and freebie were definitely well worth the effort.  To date, I have had bass players, guitarists, keyboardists, vocalists, and music all played through the built speakers with nothing but compliments given.  I give kudos to the PRV line for the quality put into every product purchased thus far.

Rated 5 out of 5 by from Very punchy mid bassI've tried a pair in a sealed 0.5 cu ft enclosure as a mid bass in an automotive application. I'm sending them 110 - 800 Hz as part of a 4-way system. They do a really good job reproducing snare and kick drums. Paired with two Dayton 10" Titanic III's, they reproduce a darn good low end and they are a winner in my book.

Rated 4 out of 5 by from Replacement for EV ZX-1Sounds as good as the original for 1/3 the price. We use them at church for que wedges. I will buy them again when I need an 8inch speaker.

PRV Audio 8MB500-NDY Neodymium 8" Midbass/Midrange Woofer 8 Ohm

I would like to use this speaker as a mid-woofer, from 80 hz on up to about 2500-2600hz. What would be the best enclosure and power handling. I wildbill

Asked by: wildbill
The recommended enclosure is 0.35 cubic feet for this driver. It will only handle about 100 watts before excursion becomes a problem at 80 Hz, so if you want it to handle the full 250 I would recommend a high pass around 150 Hz.

I plan to build 2x8 pa boxes with these, using a horn of course. I'd probably cross over about 3.5k but I'm wondering where to port these in a roughly 1.6 sq ft box. I would like to run these speakers close to max output if possible. 

Asked by: fingersg
I would recommend a port that is 4" in diameter and 4" long for a tuning frequency of 54 Hz. If you want these to handle full RMS power, I would recommend high passing them at about 150 Hz.

I want to use this driver down to the 50 to 60 Hz range. What would be the power limitations based on driver displacement limits?

Asked by: Gregor
In 0.43 cubic feet sealed this driver will only handle 45 watts before excursion becomes a problem at 48 Hz. In a 1 cubic foot vented enclosure it will handle 50 watts before excursion becomes a problem. These are both considered optimal alignments.

what would be the optimum ported enclosure volume and tuning factor for this driver (used as woofer) ?

Asked by: db dave
The optimal vented enclosure volume for this woofer is 1.3 cubic feet with a 3" diameter vent that is 5.5" long. This will tune the enclosure to 44 Hz.
