Product Details

Visaton SL87 FE-8 Ohm 3.4" Full Range Speaker 8 Ohm

Visaton designed the 3.4" SL87 FE speaker for flat frequency response from 100 to 15,000 Hz for use in small high fidelity speaker systems and for thin, column array speakers for personal professional audio use. This driver is also weather resistant for permanent installations in humid environments and for outdoor use.

A spun plastic cone is combined with a rubber surround for self-damped output without the need of a crossover, while offering IP64 protection against dust ingress and splashed water when installed in a proper enclosure. The large ferrite magnet keeps Qts down to respectable rating of 0.65 for true fidelity and a small enclosure requirement, while increasing sensitivity to 87 dB (1 watt/1 meter).

Visaton SL87 FE-8 Ohm 3.4" Full Range Speaker 8 Ohm
Visaton SL87 FE-8 Ohm 3.4" Full Range Speaker 8 Ohm is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Great full-range speakerGreat quality speaker. A bit on the heavier side of things, so take that into consideration for your project. Super responsive on the midrange-treble spectrum, though it is lacking on bass punch. I have this serving in place of a tweeter along with two Dayton 3.5 inch full range speakers supplying that bass power.

Since no specs are given, what would be the optimum cabinet as well as port size? Hopefully an f3 around the 60's? Thanks, John

Asked by: fastjohn
The recommended volume for this driver is .14 cubic feet, but it won't really be possible to get an F3 quite that low. A 1" diameter, 1" long port will tune the box to about 90 Hz and have an F3 of 76 Hz.

This appears to be a great driver as it has high SPL and is weather resistant. You don't appear to sell a compatible grille for it? Visaton has P/N Grille FR87 which is made for this driver. This would be nice to be available.

Asked by: Digital_Steve
We may be able to special order the grill for this. Please call or email our sales department for a special order request.
