Simplier, smoother, more versatile, a bit taller... discontinuation of FE126e had us starting over, hence FH Mk3.
After a couple iterations and a failed alpha build, we trialled a design at the recent VI diyFEST we are happy with. The alphas were built with removable drivers and we tried it with FE126En, CHR-70, EL70, and Alpair7, Now we are ready for some beta builds. ![]() ![]() dave Frugel-Horn Mk3 Builds & Build Questions (current plans posted here, see post 1 for where the most current are) FH3 Picture Gallery Short cut to the plans: http://www.frugal-horn.com/downloads...1v0-060518.pdf

Looks more like a rear firing folded voigt with a horn thingie attached to it. Wasn't the original frugel a true horn. That would account for the unique sounds these two cabs make. Still, a very graceful appearing speaker cab- regardless of what you want to call it.

They look somewhat like a folded voigt pipe or straight pipe. I wonder the effect of the curved rear opening? I'm sure it alters the sound but curious if there is a reasoning behind it. This design looks like it can be unfolded so we can all start building things like we used to for the RS 1354 and 1197. I love the simplicity of the folds. Btw, are those BIBs in the background? Also, i wonder if a 'simple' build can be done with 90 degree angles and just an opening at the rear without the curves. Perhaps a less ambitious design but satisfying... then we can all buy drivers and start building again! I'm excited about the new design! Thanks for sharing!

Would that make it a hybrid as it appears that the throat of the horn starts at what would be seen as the exit port on this particular example below:
diytube.com :: View topic - Show me your DIY Speakers ! That would make the rest of the cab a 'tuned' compression chamber where the higher freqs are filtered out by the length and folds of the transmission line prior to reaching the throat of the actual horn. Would raising the height of the 'throat' to the width of the line proceeding the throat and extending the length of the line to tune the frequency be more in line with the definition of a true horn? Or at least qualifying as a tapped horn? Still, I love the looks of this new cab. Looks like a fun build. Maybe some variation to accomodate the b20's could be in the works? Now would be the time and palce for that now that they are available on the cheap for expirementation. |
