Before experimenting with the Hi power Electrostatic module, I used 416's in my large corner horn. They sounded extraordinary (ran with inf baffle to basementand made me realize how much Altec/JBL enclosures suck with their poor deep bassperformance...

[quote user="el`Ol"]Maybe one should't give up the attic-IB idea, the subs could fire downwards.http://www.aespeakers.com/drivers.php?driver_id=8[/quote] Great idea, thanks for reminding. That still might be an option. I need to educate myself about...

[quote user="Romy the Cat"]Anyhow, I did the measurements today and what I saw shocked me. Of the ULF sections has nice 20Hz at MF level then they have +12dB at 60Hz level. That explains everything but it also absolutely clearly indicates that the se...

[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...

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....

Thanks, Wojtekm it sounds like interesting experience. I would mention that you use K-horns and with them the loading would be much more capriccios then it would it be with stand-alone infinite-baffle bass section. Did you seal the space between the ...

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...

Unicon,
If I understand you correctly then you proposed that tightening to loosening screws that attach drivers to baffle made a lot of difference in your case.
I never come across to it. Tightening to loosening of screws would affect the ...

i found the Fujitsu ten team (Eclipse co) brand new.they have paid the desired attention to subject.http://www.coherent-audio.de/download/e_TD712z_Catalog.pdfthey dont refer their technics in baffle assembly is correcting time domain(phase)but surely...

I believe that the Arum Cantus is typical of most ribbons in mirroring one of the principal failings of MC cartridges, a rising top end (over 20k), although I have not actually heard this - at all - with my own small Arum Cantus, and I just go n...

Hi Romy,1) What dimensions for 1808 baffle would you suggest? 2) Is floor-firing vs. front-facing cone useful or preferred?I believe you wrote LF channels should be placed in arc outside midbass channels. 3) Any *general tips...

I made the move toward to what I think might be done with Injection Channel for my Macondo. In the picture below is a new home for the 10-incher Red. The box is done interestingly. The front baffle is 1” MDF all the rest is 3/4n if a regular cheap pl...

Well, a lot of horns are put into box enclosures of course. This is really a complicated subject. The baffle must be dealt with in a manner similarly for all loudspeakers so designed of course. More interestingly is the potential fo...
|
|
Actually it is very possible that it might be so. I made some rudimental measurements and concluded that RAAL tweeter and JBL midrange mounted in the same baffle has non-perfect time aliment. So, I will need to use gaskets under the drivers to time-a...

[quote user="Romy the Cat"]Sand damping it beautiful, it is well-recognized, but you do pay cost for it, in your case the cost is space. [/quote]I know that Romy… but without the massive amounts of sand, there are always some vibrations felt when I t...

Hello el`OlCan you better describe "the center of the wavefront is moving backwards" ? You mean the sound wraps around the speaker differently dependent on the wavelength compared to the baffle ratio i think ?This is also true for horns (not only for...

Romy:Thank you for your response. You are correct that the vision is not completely developed for this 4 way. A bit more info is needed. I've had some experience with JBL woofers, but am relying heavily on the results achieved...

Romy,If you havent already, why not explore the Infinite baffle concept? Or a long terminated back chamber for that matter.Current drive should also be very good on the lower registers.Rgds, Collin...

[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...

I completely agree that in a home setting, even if you love "Drum & Bass" and Hip-Hop, you will never ever use anywhere near 2" of cone excursion.

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...

I recently spoke with Paul Eizik regarding the criticality of the open-air mounting of that driver instead of baffle-mounting. I decided to go extreme and to get rid of that plate that I had under the driver no mater now small it was, also I thought ...

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...
|

I think you’re onto something in it. Those Lowthers in fact might be not unfavorable candidates to use with horns at all. An open baffle at 150Hz? Perhaps, although I do not feel that Lowther can handle that exertion with a necessary integrity,...

Well, this for the tip of multi-layering the vertical panel. I like it a lot. I will allow keeping the mild panel thinner and more “airy” visually. The total high of the thing will be not 8’ for rather somewhere slightly above 6’. Also, I review the ...

The Western Electric L-9 in Munich was/is an infinite baffle design. The 754B woofers are in a sealed enclosure with a front horn. There is no possibility of cancellation between front wave and back wave of speaker, so I wouldn't call it an "open baf...
