Frugel-Horn Lite for 3" drivers
 
The 3rd in the series of small horns based on the Frugel-Horn Mk3 is the Frugel-Horn Lite aimed at supporting 3" drivers.

Designed to target the Fostex FF85wk, sims show that it should work with a wide range of 3" drivers (see drawings for those summed)

We built the original proto-type in early January with the FF85wKeN and have refined the design since then. As one would expect with 3" drivers bass extention is somewhat limited, but listening we were very impressed with bass reproduction. Comparing to more bass capable speakers, they produce the 1st harmonic very well, creating the illusion of deeper bass. This will satisfy many. Higher frequencies will depend on the driver used, with the F85wKeN they are very good.

With pressure on to get this out i worked on a basic set of drawings today (thanx David). Please contact me with any QC input.

Ok, I see it if I download the PDF just not in the image in the post. The dimensions are very close to what I ended up at for the foam core homage.

Thank you for the plans. Going to have to add these to my list of near future projects.

do you reckon a TB W4-657 driver would work on this enclosure or would a bigger Frugal be better?

FH3 would be better.

Thank you very much for this new plans and especially for your efforts for this community. It's a pity that you guys are so far away for me.

Only thing that is curious to me, this build should run for the Aura NS3 as well as for an Fountek FE85. No criticism at this point, I got both drivers and will give this build a try :)

Need to leave work early today and buy some sheets of wood :D

Frugel-Horns have proven to be quite tolerent of faitly different drivers, adjustable damping is the key (reminds me i need to add a damping drawing).

3" drivers tend to cluster closer together spec wize so many should work.

Wood isn't needed; this FH is clearly thought for a carbon fiber execution due to the relatively little size
