In Reply to: RE: Down-Firing Straight Edgar Style Mid/Bass Horns posted by the carpenter on November 15, 2014 at 11:17:51
Hey John!
I'm glad you checked in!
"The reason I don't fire my horns downwards is that when the axis is horizontal the mid bass horns are a dandy table top for my large paper mache horns."
The Tune Audio had a good mounting solution, and so does EduargG. There are many ways to skin a cat.
"Another thing: in the mid-bass/mid-range, reflected sound doesn't sound as appealing to me as it does when looking into the throat of the horn. "
I have no doubt you are right. I'm guessing a straight M/B horn sounds better than a folded W horn, but speakers are all about compromises. It seems the compromise with horns is always the size. It's a way to get a big horn in a small room. How 'bout this? A really big horn in a big room? Of course, I'm talking to the horn maniac. I'm surprised they ever let you out of this place. Taking your meds?
"I enjoy all those little nuances in the mid bass region and a reflector diminishes the details."
I bet you do.
I had a little list of advantages of the DFSESMBH. I'll be back.

Hi Jamie,
Good to see all the avid interest in horns, especially the larger variety. When I say a "dandy" table top, I'm basically saying that the throat of the paper mache horn is at ear level when setting on top of my mid bass horns. It's just a natural way for me to do things, considering I have a large listening room.
For the average listener, their room will most likely be smaller than mine, and I can understand the need to economize on size.
If you want to make the horn compact, consider the crescent horn on my web site. It's vertical (for the most part) and has a gentle curve that won't destroy the musical details. If you want a really compact design, one could always design a mid bass horn that spirals like my bass horn. When I have more spare time (??? what's that ???) I'll design a spiral version.
In the mean time, because the spiral bass horn is extremely clean up to 200 hz, I'm designing a 150 hz mid bass horn to take the place of my current 100 hz unit. Instead of using the B&C 12PE32 it uses an 8" B&C 12PE21 driver. The 8" cone is light, the motor huge, the Qts low, and the response is spectacular. This will become my new mid bass horn. I'll be posting it on my site, soon.
Hi John,
Your spiral horn certainly deserves it's own thead. If you wish to discuss it, and answer questions about it, at least until you get bored, then I will start a thread.
Love your work!

Hey Jamie,
A spiral bass horn thread sounds great! Thanks for taking the initiative to get a thread going. :)
Woohoo!

If the mountain won't go to the prophet, then the prophet must go to the mountain. How long will the 150hz horn be? Not to many horns out there designed for a lowpass of 200hz. That makes it kind of special. Or will it be 150 because of anullment? It could be used with any number of PA friendly bass bins. Bill Fitzmaurice, big PPSLs, your own folded bin. Lots of options at that crossover point, and never anything but PA style horns to cover it. I never tried any of them.
110db efficient?
