Fountek FR88EX 3" Neodymium Full Range Speaker Driver

Fountek has applied much of what it has learned from designing industry-leading ribbon transducers in creating its line of full-range drivers. These high-performing cone drivers feature thin-foil aluminum diaphragms that shed resonance rapidly, for exceptional detail and smooth frequency response.

The FR88EX model features a high-strength neodymium motor structure for low distortion, extended excursion, and excellent transient response. Its advanced design makes it a true high-end contender in small full-range drivers.

Fountek FR88EX 3" Neodymium Full Range Speaker Driver
Fountek FR88EX 3" Neodymium Full Range Speaker Driver is rated 4.6 out of 5 by 5.
Rated 4 out of 5 by from Great for a FullrangeI bought these guys to see if they would work as a tweeter. They're just not quite crispy enough on the high end, but in a little ported cabinet they're great for little desktops. Add a little 3/4" dome tweeter and they'd be fantastic desktops.

Rated 5 out of 5 by from Good Quality - Sound within its limitVery well built speaker. Excellent highs and upper midrange. Given size of speaker, there is a substantial drop in sound pressure for the lower frequency range. I am using these as replacements for midrange speakers in a Porsche 928 and am very pleased with the result.

Rated 5 out of 5 by from Fantastic sounding speakerI put these in a small ported enclosure, and cannot believe how good they sound. Impressive amount of low end for such a small driver. You will not be dissapointed.

Rated 4 out of 5 by from Above average widerange.The FR88EX driver makes for a fun project. I built a set of desktop speakers and a set of mini-towers to give as gifts. I was very pleased with the sound quality and would have given them 5 stars if I hadn't made the mistake of putting them head to head with a set of Fostex FF85k drivers. The Fostex FF85k (and now FF85wk) is only a few dollars more but works better for near field listening and doesn't have as much break-up at loud listening levels. The Fostex FF85wk also excels at producing crisp clean highs. The Fountek FR88EX in comparison sounds brash. The mini-towers were the better sounding of the two projects I completed but would still require a subwoofer for pop and rock music.

Rated 5 out of 5 by from Amazing driverI am using this in a 3 way setup in a vehicle, I would love to use it full range, but I ended up needing a tweeter due to it being mounted in the dash and extremely off axis. I have heard it in full range in a house application, and it sounded great also. I have it crossed over at 200hz @ 18db/oct and 5khz @ 6db/oct. Blends with other drivers great, and has amazing clarity, stage width, and focus.

What is the best way to mount this?

I purchased this driver not too long ago and I'm having a little trouble mounting it. The screw holes are very small, even #4 fine-thread screws dig into the driver frame. Is there a recommended size (probably metric) and/or method to mounting this driver?
Asked by: niemo
Unfortunately there isn't a specific screw that is recommended for this driver. Your best bet is to bring it to the hardware store and fine the best screw for the mounting holes.
