Flattest response between 2000hz - 20 000hz

[Mr. Widget]

WW,


Most of my posts here are usually 'pooh-poohed’ on the basis of the specious ‘theory vs. practice’ argument. This is utter nonsense as the latter is nothing more than implementation of the former when a rational design path is taken. If the recommendations made are followed intelligently, coupled with some modicum of craftsmanship, superior results can be obtained. Bent nails are not the fault of a misused ball-peen hammer. Loudspeaker components designed to cover an audience at a rock concert are usually unsuitable for use in a confined, at-home venue. Typically, when modest equalization makes the music 'sound bad', what is being revealed are imperfections in the source or other system component(s). The degree of signal mangling that takes place to get to the recording stage makes what happens afterward some what a trivial matter so long as the reproducing system is of decent quality and not in need of repair.

Regards,

WHG

I agree with you completely. Except for the part about your posts being 'pooh-poohed'... I certainly don't disregard your posts as being too anything. I think they are thoughtful and on point, though I may not always agree with your conclusions. ( I probably agree with more of what you post than you think.)

In your post above about PA gear and bent nails, we are in 100% agreement. I don't think my posts on this thread are incongruous with your rationale.

BTW: The TD4003 is not a PA driver. The TD4002 is typically used in that application, but they are very different animals.

PS. Just read Rob's response... I too thought of the venerable 375 driver and it's many uses. I would suggest that the drivers themselves when well designed as are the 375 and others, are fine in any application, it is the implementation that makes the difference. I would never use a PA horn on a driver for use in my listening room. Beyond that there is also personal preference. There are many who enjoy a 2370 horn in their living room... I wouldn't.

[Mr. Widget]

Along with the B&C drivers I have heard good things about Beyma. The initial question though was what is the flattest response.

I would suggest that while the drivers do matter, since most drivers made today from JBL and others are all quite good, the horn will have at least as much if not more of an effect on your final sound.

How can I calculate the right horn for a horndriver? It must be a small
horn, maximum width is some 18 - 26cm

I'd go for the selenium horn HL14-50, as in 50mm driver.

Totally neutral in sound and doesn't cost a fortune.

It is affordable at under $30ea.... might be a bit too beamy for my taste.

Hello,

I recommend the BMS 4540nd and DDS ENG 1-90 Pro horn.

The bms costs a bit less than the B&C mentioned above.

I think you can also buy the jbl 2407h which appears to be the 4540 as well.

The DDS horn is a bit over your spec at 27cm but works well with the 4540

Why do you think that it would be a "problem"? How often do you sit outside the sweet-spot when you listen to music and/or don't you toe in the speakers?

I have never felt any "beaminess" while listening to these horns.
When coupled to the 2441, the listening angle is wider than the graph shows, I'm sure, all the way up.
EDIT: Besides, I do have a 075 on top as well, so I really don't think there are any drawbacks in using this horn.
Only when crossed over too low, there is a slight coloration, but then again, that goes for all horns.
But other than that, the horn is as "clean" as can be IME.

I dont want a sweetspot, it should be no sweetspot.
I´m not alone when I watch a movie or listen to music.

Low distorsion, uncollored, flat response, no sweetspot.

You are going to have a problem then. I use 2344's and you are not going to find many horns that can throw a larger image across the room with there 100x100 coverage. I use them in my main system which doubles for both HT and music. The sweet spot they have is larger than the 2307/3208 lense combo but is still well defined. The timbre doesn't change as you move off axis but you loose your phantom image just like any other speaker when you go off to far to one side. I would look into the 2600/3100 horns providing you can place them correctly. They were designed for exactly what you seem to be looking for.

Is it not the tractrix wich have the best dispersion?

[Mr. Widget]

Ditto what Rob said.

Tractrix horns have a very tight and confined sweetspot. The only way to successfully play movies for several people is using an actual center channel unless you are willing to accept a major compromise.

I thougt tractrix was the horn wich had the best dispersion.
It´s not only about movies Also music HAHA !

Well, it´s hard for me to explain in english, but I thing
you all understand what I´m out for.

[Mr. Widget]

Never. With horn speakers I almost always toe them in.

I am not sure that there would be a problem... I was speculating. I do find the 075 way too beamy for my taste though. I suppose like everything else in this hobby we all bring different expectations and requirements to it.

What does "beamy" mean?
