thanks I have a few questions to ask if you do not mind:
1) Did you experiment with surface of the horns and a negative contribution of smooth surface to Sound?Smooth surface are fine don't waste my time on a trival matters.

I am going to show two different simulations for a 105Hz
tractrix horn with the same 8”driver (B&C 8PE21). The parameter values for these two
simulations are quite different. However
the simulations predict the same great flat fre...

Yes, proper upperbass is what I am l longing for. In my current system, folded horn going up to 350hz is not satisfying me and was the starting point of this project. It colors and kind of covers up the sound of big bands and orchestras...

[quote user="George"] I am not quite understanding part of what you say:
"It is very difficult to make a generalization about it but generally this quite “large bloomy space” will be a space equal to, I would say, 1/8-1/12 of the room ...

[quote user="Romy the Cat"]Folding introduce a bunch
of resonating chambers and cost audio coloration in most of the cases that do MASK
OUT the transient dynamics but folding itself should not have an impact to dynamics

here's the measurement we've got from S3 on tractrix 260 horn.
the increments on the graph are 1db
it seems useful from around 450-500 to some 1.3k, but it still looks very bumpy in comparison with a number of ot...

[quote user="Romy the Cat"] I do not use compression driver
for bass channel. I would like to have my system esthetically balanced, to get let
say 120Hz from a compression driver would take too long horn and it would be no
way time-aligned it. So,...

I'm a new reader of your website and one subject which interests me a lot is that of upper bass horns.As you have noted time and again (with which I agree almost completely, after reading a lot of 'research' [many claiming to defy the laws of physics...

Thankfully, JMLC chose to use english as the common language for he event, not altogether surprising given the many nationalities that probably attended.JMLC writes:

Romy,I'm new here, and I have read your posts in the forum. I
have some questions that relate to this post of yours: 'The midbass horn is
a pain in ass, a big pain!!! The GOTO-Jackson horn went for the very noble
small throat size – somethin...

A visitor sent me email “Imitation is the sincerest form of flattery” with a link to (I presume Australian company http://www.goldstandardaudio.com ) that does this:

wow. So much to digest here.
Further thoughts.This is where I’m at.
It
seems that I don’t have the space for optimum straight horns exiting directly
onto the listening position as per Romy’s diagram. And besides,...

Nine years ago, when I posted the initial post in this
thread the Aries Cerat was a different company with different products.
As I understand in 2014 they changed a lot and today they have a speaker that I
would like to talk a little: Aries Cera...

... or wondering if it has any new insight into horn design.I did not read the book but I find funny that person who presumably do not “believe” in horn write a review about the presumably horn related book. It would be similar to ask a blind person ...

[quote
user="jackydai"]My basic point is: the flare rate has to be coherent
right from the entrance of phase plugs. In this sense, not even Bruce and Sam
did it right, I’m afraid to say. In many cases the driver and the horn are
designed by diffe...

This there is the last in the “THE PROBLEMS WITH HORNS” cycle. The previous threads might be found at:
Problems with horns: tweeters.Problems with horns: mid-range horns.Problems with horns: mid-range drivers.
This would be probably the most contro...

Jorge,
You're quite welcome to visit any time you are in the SF Bay Area.

Romy, I use MDF primarily, plywood occasionally and solid wood if I am forced to.
Round horns are precision CNC made within +/- 50 microns.
However, during sanding and finishing process the accuracy is somewhat s...

Some of you
have already seen my old posts about the 2 pair of concrete midbass horn a
friend and I built a few years ago.
Now I just
