The Fibhorn Model 6c

Model 6c

(Click for full-size image)


The Model 6c FIBHORN may be the WORLD'S BEST under $600/pair speaker. It has the combination of 3 design features that make every one of our designs unique: a  full-range SINGLE DRIVER for seamless musical clarity, a FIBONACCI sequenced horn cabinet for totally accurate reproduction and the U. S. Patented EnABL process for vanishingly low distortion. You will hear the NATURAL SOUND & SPACE of the original recording session for the first time with each record you play.


The Model 6c has a larger driver and cabinet than the Model 2b, our candidate for the WORLD'S BEST under $400 speaker pair. We use the superb TANG BAND W4-1320SJ 4" driver for its excellent sonic characteristics, including the deepest and most accurate bass response we have ever heard from a driver of this size. (We also build the 6c with the FOSTEX FE103En driver, as pictured with the cream color cabinet front panel.)


The easy-to-install ISOLATION SPIKES further enhance the unequalled value of the 6c by eliminating micro-vibrations. This feature adds to the realism of every record that you play.
