Interesting video. It is a compelling argument for open back, infinite baffle or transmission lines designed to completely absorb the back wave. Everything else simply works much differently than we want to believe......

I think the usage of Romys Injection Channel has misguided you to think it was implemented because of a certian lack of tone or some sterile sound, nothing of the sort, I cannot blame you for not having listened to Romys system, but theo...

These speakers were not open baffle. I would agree with Mani's description of their sound, except for the 'edge' bit. That depended on where you were sitting/standing....
|

Weren't these speakers (at least in Germany) normally used built-in (infinite baffle situation)? And I don't like the word "open baffle" because it can mean anything. It reaches from quasi-IB like proposed by PHY-HP up to that more and more crazy con...

There seems to be a lack of useful feedback on the actual sound quality of these oddball, relatively rare TAD mids. So I think it would be helpful to share some basic observations I gather after listening to them for a couple of days. I install these...

I had a look at the pic of your speaker just now - may I ask about the reasoning that went in to choosing a diffraction type horn?Also, your midrange looks like an open baffle type. What kind of back wave/diffraction management do you use? Kris...

[quote user="Wojtek"]I use regular Lowther DX4 (ENABLED) . I don't think the 250-400 is stellar and I'm still waiting for the extension to try small throat for lower midrange (2,75") (B&C 8P21E driver) for 200-1000Hz .[/quote]Look...

[quote user="msaudio"]Your Typical Acoustical Suspension-type Loudspeaker enclosure witch has less then 90 db at 1 watt does not belong with a horn system that starts at 110db at 1 watt, even when you ad more then 1 driver, it is still way to far...

[quote user="Joe Roberts"] Yeah, but plywood is cheap and the result is audibly noticeable. Baffle extensions were recommended for all of the Altec VOT cabinets too. Make a big improvement for cheap if you have the space.
As the frequency dec...

The only reason I don't have a giant WE system is that I can't afford it and I don't have room. I sold all of my WE and Lansing field coil gear to my Silbatone friend back in 1989, because I know he would never sell it, he was putting together a ser...

Chirag, First off all you have to define what do you want from them. If at this moment you’re looking for something within $700 then very next year, when you finish you medical school you will be searching in very different price range… :-) Now a lit...

Well, you see, the outer dimensions of the mouth of cause an indications of low end response and by objective evaluation of it is easy to estimate horn’s bass numbers. However, it is very far from “sufficient” assessment. A few years back I completel...

Fist off, hello to everyone. This is my first post here.I have a DJ/listening system in my basement. Mostly, self made. Some pictures:http://picasaweb.google.com/noviygera/BasementSystem#Just recently i installed new Funktion-One RES1.5HS horns. Pict...

Thanks, Guy. JC Morrison? I am not familiar with this character well. All that I know about him the he pop up usually around Joe Roberts and they perfume act of public saliva liking. It does not say anything about his amps, however, neither about his...

Hi Romy and all,
first of all, my name is Henry, with a "Y". due to an Irish grand-grand-grand father called "O'Henry". the O' was deleted when my grand-grand father was born, due to a silly servant of registry office. :-) all my horns uses the calc...

So, you are thinking about 3-way installation with GOTO bass, Lowther mid range and some ribbon atop? It is certainly no one knows how I might end up: try it, post the pictures and let know us how it went.
I can see a few points where you might need...

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...

[quote user="cv"]A couple of things to correct
here - the horn flare is not conical even though the exterior surface gives
that impression. [/quote]
I think you are incorrect. Even if the horns do have some internal
belly then they still look m...

II would like to pass a word of warning about the C-15W driver. I do not know this driver but it looks like it has dual voice coil. This might be a hell or blessing. On a paper the idea sound very interesting but unfortunately when I seen it it never...

To me the big green drivers in the midbass horn look like old Siemens Klangfilm or Telefunken (or other German manufacturer) 10 inch units. Maybe 12 inch... I had a pair of 8 inch Klangfilm once and they do have interesting tone across a couple of oc...

I am taking about a “Default Evaluation Loudspeaker”. Let pretend that all people who do SET appointed one single full-range driver: like some kind of Fostex of Feastrex… and all agree that the driver is placed dead center of 100cm by 100cm open baff...

Well, the first hurdle is matching efficiency from a dynamic driver to over-the-top horns like yours; but perhaps for others with somewhat lower efficiency horns...http://www.supravox.fr/anglais/haut_parleurs/285_GMF.htmI have had my eye on this one ...

I don't want to get off on a tangent here, but I have been using a sort of MF injection by default for some time due to OB backwash from my DX4s between 150 and 2,400 Hz, since I leave the back of the driver open. Yes, this is "out of pha...

I do not exactly understand what you are proposing at DiyAudio site. I have generally an attitude against dipole radiation, and particularly in bass. There is a common believe among audio people that dipole bass has advances, there was a lot of said ...

[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...

Romy, Can you expand a little more on what the issue with dipole bass is and what it does incorrectly? I'm still not sure I know exactly what you mean (and I've had a look at some of your other comments on the site).What sonic aspects in particular? ...
