Introduction
The Frugel-Horn
Mk3 (the name is a cross between flugelhorn & frugal) is a redesign of the original
Frugel-Horn with goals of
simpler, smoother,
more versatile, a bit taller... all have been met, and driver versatility has proven
to exceed hopes.
A recent review of a commercial FH3 build/system.
The 1st build was a prototype shown at the August 2010 VI diyFEST (4 years after
the original with debuted at VI diyFEST
2006). These had removable baffles and worked with FE126En, CHR-70, EL70, and Alpair7.
Since then 100s of pairs have been made, and they have met with critical acclaim.
Even prompting it being called a "timeless classic".
A number of other drivers have proven to work, Fostex FE127e, FF125wk, FE138eSR*,
Mark Audio Alpair 7.3, Tang Band W5-1611, and a number of mid-woofers, with more
expected to be fitted. Fine tuning is done with damping placement & density,
room placement, Drivers like FE126En can benefit from a corner, drivers like Alpair
7.x or CSS EL70 have more latitude, and in many cases will need to have the LF levels
reduced.
Deflectors & supraBaffles are optional. Woofers have been built into deflectors
to give stealthWoofers.
*(FE138eSR has other issues no cabinet will fix) |
