'Short' horns


I rarely see anything related to this subject but want to know the experiences and opinions of those who have used either speakers that utilize short horns, or the experience of anyone who has attached them to an existing speaker. I enjoy experimentation with just about anything audio, so these are on my list.

There's a really neat, short, oval horn design out there I've seen become popular in home kits, do check them out.
Erik,

  Thanks again. Yes, no doubt there is a mountain of horn designs as well as many others. I have been fascinated by speakers for decades going back to my early youth. The first speakers that I ever built in '76 were a knock off of the K horns. I built them in high school shop. The bass is still unforgettable to me, but the midrange is where things didn't add up as well. The tweeter used was the K77? Sounded fine. Anyway, it has just gone from there and has been a great experience.
So glad you've had so much fun, and that's what this is about, when it isn't about education and culture. :)
 I was born with 'what if' in my head. That can be good or bad, but the side of curiosity led to can this be done better? Often times the answer ended up being just more experience under my belt. Then there are those times that something really shouldn't work, or at least work as well as it does. 
 The target relies on a bullseye to make shift the rifle. The eye tells us the score, and that is enough for that approach. Perhaps I am attempting to shoot over the shoulder while using a mirror. More than that, I am not even aiming at the same target as most others. Could be that after I fire, a theory falls.
I do quite a bit of DIY.  Right now I’m listening to a pair of 2 way speakers with a 6.5” woofer and a 3” wide-range driver mounted in an 11” diameter turned maple horn.  Design is similar to the Viking Acoustics Berlin.  To my ears, the sound is quite good with excellent depth and imaging.  I also designed a pair of LeCleach style horns for the same driver that I’m waiting to get back from the finisher- they’re quite amazing to listen to and sound far better than just mounting the driver to the cabinet baffle. Both styles are fairly shallow.
