Spawn of Frugel-Horn
 
2 Attachment(s)
As you know Scottmoose has been helping out with MJK sims of the Frugel-Horn (since MJK as yet doesn't do 1/8 space these are only of interest as a design reference when compared against one another)

Anyway, this spurred Scott towards implementing some of the stuff floating around in his brain and has spawned a new member of the Frugel Family... if the original Frugel-Horn is the mama, this is the tall-gangly -- but smart -- teenager.

Inspired by Terry Cain's double mouth BEN series, the Replikon (discussed here http://www.diyaudio.com/forums/showt...threadid=55721 and conversations with GM about the big box (CC) long exponential port bass reflex style horn as respresented by the Replikon, Scott came up with a box that is very tolerent of differing driver parameters. It also requires no curves to be cut.

Scott is building the 1st prototypes now, and will hopefully get a chance to let them get a listen at the upcoming EggFest.

The working name for this horn was the FrugelBEN, but unless Terry Cain gives his blessing, we'll need to come up with a different catchy name -- DoubleFrugel is kinda derivative.

I haven't got detailed plans ready yet, but i will, in the next series of posts, attach some teasres.

Some ealy renders to give the idea... the post of the tarted up one that follows has the most recent rev of the internals

This one shows the proper internals, but also some liberties taken with respect to moving it away from a retangular box...

The modeled response of 6 potential drivers -- it can be seen that the box really dominates...

And the current rev of the plan...

I just finished the Frugel-Horns, now you are making me want to try building these... d*mn you and these good designs.

Looks great

Thanks,

Josh

I like the way MetalMan put it, "quit pushing my woo-woo button". I said no :)

I've been up at school for a couple of days, school starts tomorrow and the shop is about 100 meters from my dorm. My roomate is in the design school, so maybe I can use the shop, hopefully they have a CNC :D

Do the really small throat and large mouth area have anything to do with the reasonably driver independent response?
