Even if you add in the cost of the Cornu project to the $24 for the Vifas and $6 for the foam core here, the mini-FH3 is still a great bargain. And a bunch of fun as well!
Agreed. One of the best sounds around for $30/pair, and a lot of fun.

I can't seem to open the audio clips. Windows say they are not compatible. Any clues for me.

Sorry about the mixup. Here are the files re-uploaded as true zip files. They have been tested to work this time.

Default FH3 Inspired Bipole (?)

Hi xrk971,

Have you tried your FH3 inspired layout as a bipole? Looks almost like a natural for that.

Regards,

No bipole yet, but maybe one day... It is not as simple as cutting a hole in the back - the volume has to be doubled along with the vent CSA. So it would be a complete rebuild. My attention is more on a Synergy or a Karlson type speaker lately.

Hi xrk971,

I have seen your first try at a Synergy/Unity horn. Someone posted a link that has a lot of good information as to the location of the speaker entry holes, etc. Good luck with that one, a very interesting design.

I still think a bipole FH3-Inspired would be interesting.

Regards,

I finally got around to building a pair of FH3 Foam Core Mini using Aura ns3-193-8a1 drivers that I had on hand. I basically used the dimensions That X provided a year ago with one modification is that I changed the back of the flared sides to 10" instead of 12.
The build didn't go as well as it should have; they aren't square- more a parallelogram .
I only had enough felt to cove the back panel and used poly stuffing around the driver.
Sound is fairly good the mid and upper range is very good but lacking a bit in the bass. I'm still messing around with the stuffing as you can see in photo 3.
This is a good fun project- Thanks X for getting this one started

cheers

Prezden,
That looks great with the stained plywood! Congrats on another build. You were going to build a Met that I sim'd for you at some point or did that morph into the 24 in Cornu? The stuffing makes a huge difference - very light amount below driver - loosely pulled out and just an inch or two.
