Well, it unquestionably much better, still I am afraid that they are trying to spread one ass across two chairs; I will talk about it in the end. The change from what was before was around the frame and upperbass horn. It looks like the guys are tryi...

[quote user="Marc HENRY"]hi all,thanks for your interest !yes the frame is curved, HF and MF are //yes there is a phase plug in the bass horn. This cover 80-300Hz.there is a separate infra-bass section, covering 20-80Hz.images of the bass phase p...

Interesting take on the Altec 820. No way can this be done for 20k. Looks like dipole bass with some attenuation for mid frequencies.Wolf von Langa has a faintly similar take on the Altec 820: [url]http://www.holgerbarske.com/allgemein/fremderregt/#c...

I realized that this thread is slowly becoming the most sophisticated web recourse about Midbass Horn available. Trying to keep the thread educational I would like to introduce to my readers one more objective of my project. The subject is super ...

Thanks for the detailed answers. I will explain my setup.You are right about the dipole bass correction instead of the injection channel. Since I am waiting for both a subwoofer and the Fane Studio 8M and their horn, I am using the 12" as a b...

I really enjoy this site. Romy has a fresh view that is actually easy to understand, if one simply reads instead of interpreting what he writes.Still, a view from "higher up" is something that many of us are not privileged to. Looking at the major co...

[quote user="guy sergeant"] The bass system had the two pairs of drivers facing each other into a 12" wide 6ft tall 'slot'. The drivers were open to the rear. I think this had been put together just prior to the show.[/quote] Ah, the slot-loaded, fac...

The first and the bigger thing that I like about them is that Anima is trying to use the vertical-horizontal configuration where the bell of the vertical horn serves as frame for horizontal channels. I love this idea and had a number of my own th...

[quote user="Romy the Cat"] 1) Horn loaded drivers are narrow-bandwidth transducing system. The wider range a horn channel covers the more it conflicts with restrictions of own topology.
2) All channels shell have strictly parallel axis

[quote user="haralanov"]Vasyachkin,in the context of your question, there is a very big difference between bass driver loaded with slow and fast expanding horn contours.[/quote]perhaps. but since i don't know much about horns i can't follow what you...

Hi Roberts, Romy and others,Before this thread vanishes in undeserved obscurity, I have a question or two for you. I understand that the issue is a complex one and should be addressed with more care and paying attention to detail than I am do...

A friend of my after reading my comments about the EdgarHorn installation in Vegas (in here) asked me why do I think the bass in Bruce’s room behave as it behaved. I tried to think about it. Some of those thoughts intersect with some other projects t...

Rakesh,Thank you for your kind remarks. I appreciate the close scrutiny you have given my previous post but I think you are at a stage of system design where many basics of your system should be considered and evaluated before the issues of my po...

[quote user="Joe Roberts"] I feel I am being objective when I say that a Mirrophonic system simply blows away Altec, Vitavox, TAD, etc. [/quote]

Joe, I think I would battle it.
I would not be so certain. Mostly the SUV sized bass horns are notoriously bad sounding despite of the assurances of the system owners overwhelmed with so common in audio endowment effect. Not to mention that the Stag...
