In terms of the length of the horn, I'm allowing myself a total height of 7'6" (just below the average ceiling height of 8'). In regards to the mouth diameter, that's another matter. (It appears that I will have to build two [2] different...

All that I will be saying are the subject of my own experience with horns and my personal observations. You shouldn’t agree and most likely you will not. That is fine with me. I have lot of reasons behind what I will be saying and opened for some cla...

If you know how in some optical systems imagery get destroyed when an aperture getting closed to F64 or even smaller, then you understand what happens in compression driver when frequency get higher and spaces smaller. Yes, the proximity of wavelengt...

[quote user="CO"] I dont need flat to 20K but dropping after 10K necesetates a tweeter. [/quote]
And there is nothing wrong with it. No one 500Hz driver that said is doing to 20K in reality does it. In fact if a driver goes to 20K then the place for...

Mjloudspeaker,
That is all fine. I get that you like them, even though said nothing about the “new” M4 sound. There is another “even though”. You do not log it into horn and like just the sound of open driver. It is absolutely not indicative. ...

The twins have a horrible night, probably the last stage of
teasing or perhaps we overplayed with them last night…. We took them from the cribs
to our bedroom and after an hour of fighting I left Amy with Abby and took Charlie/Kai
to sleep with me...
|

Listening to one of M4, connecting full range by itself, lonely like, and this is all right, is it me?,
Or are we spoiled here with sonic overtones and other things?
My testing is not complete, but verry interrestting!!
Anyone that dis...

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...

Be, if you look at the picture of the S2 then you will see that between the exit of the phase plug and beginning of throat there is a circular channel that violates my view of proper transition in compression driver. This channel is on the side o...

As can be seen in above photos, the front chamber is in reality "chamber of horrors" with highly polished surface interior, and look at the phase plug, after disassembly, I put it back together, and how can you align it? All that holds it togethe...

[quote user="Merlin"] If they are modifying conventional drive units by hand, the labour costs alone can be prohibitively expensive. The fact that they are using heavy Alnico magnets and coating the diaphrams suggests that these units do not co...

Well. That guy looks like doing nice quality. Id go there.

Nope, I never heard about those
drivers. For sure a compression driver that goes down to 80Hz might be interesting.
A few concerns I would have however.
The people who make such a
driver would not come from nowhere but they rather would b...

Electronluv,

Yes, I see the need for a phasing plug for a 40Hz bass horn. Most people choose to ignore the finer details and claim the wavelengths involved are too long to be affected by phase plug. If someone really understands the fu...
