I find the sound of my horn loudspeakers very satisfying, and by the way I have the EdgarHorn Titans, which may make you chuckle if you are a horn snob, but I think they do a very good job, one of the best commercially available horn system out there...

[quote user="Beav"] What I have is a subwoofer made by ACI; no information on the amplifier used other than it uses a two prong power cord, no ground. When I hooked it up to the APS 2000 I got a very loud pitched hum. Taking if off the 2000 an...

James, you said that “Romy seems sure that Line arrays will only work properly when used on the long dimension of the room”, still you do not defined what it “only work properly”. Wherever you put the woofers they will work – the question would...

I suspect that the 8" and 5" cones and 1" compression driver are in the Danley Signature Synergy multiple entry horn. This creates a physically phase aligned point source above 45 Hz and probably a bunch of diffraction. The double 15" woofers are an ...

I have been playing around with speakers for a long time, and things started snapping when I got into horns. I have a system right now with an upperbass horn from 140 hz turned form MDF up to around 700 hz, to another horn, and another and a super t...

Thinking about that new supertweeter or tapped horn subwoofer. This picture could give you an idea if something else in the house may be affected........

This new speakers from DeVore look interesting, though subwoofer could be better. I wish they were sealed box, but this is what it is. Unfortunately there is no chance for me to listen to them, but I'm willing to hear your idea or anyone who had chan...

If Lamm ML2 is not enough good for bass you can use crossover and add a wilson passive subwoofer.Lamm ML2 will do his job better if you use a high power amplifier for wilson subwoofers.this approach will also reduce the Port noise of wilson alexandri...

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...

Et Voila! Perfect sound forever.I am ready for a subwoofer sized battery pack by the house electrical service feeding the audio dedicated lines. Whats wrong with this solution? It doesn't exist yet? Heck, $15k in the grand scheme of things...Steve...

I remember reading about a turbine subwoofer 15 years ago called the Phoenix Gold Cyclone or Typhoon. That was for kids in cars.Tom Danley the inventor had some comments:http://www.diyaudio.com/forums/subwoofers/55122-pg-cyclone-non-cone-subdriver.ht...

My room, is 16 to 17 feet wide, 27 to 28 feet long by 12 to 14 feet high with all walls splayed, with a combination of absorption and diffusion on the walls. All electronics are fed electricity by three pure power units originally recommended by Rom...

I have tried a BMS driver a while ago and it was really bad.About a year ago i heard Berts setup at his house and it did not impress me... It was also with the coaxial BMS.Not much depth or resolution. Did have alot of power though but was difficult ...

I have never experienced anything close to "excellent" sound in a car - even without the engine running.The reflections and resonances do not kill the music, but the presentation is really DEAD. The problem is how our hearing works. Reflections that ...

[quote user="Romy the Cat"]What surprises me however is why you have expressed an interest in the high power tubes? You are with horns and even you LF sections have over 100dB sensitivity. What will you do with 120W SET?[/quote]The subwoofer still ne...

[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've had a long-time desire to replace my Edgar 80hz midbass shells with a better performing solution. My Edgarhorns arrived in 2005, and I made incremental improvements over the years until now they have little in common with the original Edgarhorn...

[quote user="Romy the Cat"]Guys, I am not looking or care about the design specifics but rather looking for some fresh idea and inspirations that would make me to think further. You see, if I shut down Macondo and measure just ULF channels then I...

Glad to hear you have found a satisfying point so that you can listen to your system.Certainly the low bass is not as critical to your being able to enjoy the system, although no question there is much to be gained from that being optimized.Trying to...

..., thanks for the link. Although I do not agree with few of your conclusions (surprise?) but the core of the problem caught quite illustratively. A few days ago a local guy called me and complained that his $22.000 2-channel loudspeakers use a chea...

Years ago, when I visited the Cogent guys, Rich was working on one of their big drivers. The diaphragm was big and even thick and heavy, as compression driver diaphragms go. Of course they used 300B amps, and the bottom end had the "sewer pipe" type ...

Hi!English's not my mother language so I'd have advices to choose wich Melquiade could be the best for me...I read that there's a lot of different versions...and I wasn't able to email Romy because of the robot barrier.I've very good 95db Fullrange B...

I have been running now a digital crossover at 20Hz, 3th order with some kind of shitty power amp. The digital crossover has a remote control. I would not say that I like the quality of my ULF but I am telling you that True ULF implementation is abso...

[quote user="drdna"] You are correct, though I believe the subwoofer covers only below 40 hz. [/quote] So??? [quote user="drdna"] This is coming from the same person who has built a 6-channel DSET? Anyway, it was more a thought about optimizing the o...
|
|
[quote user="drdna"] So, my thought was that below 35 hz, there are many ways of thinking about amplification. Some might say SS amplification is helpful due to power demands of horn loaded 18" woofers. To use 6C33 might be a trade off but I do not k...

I had a similar setup with an IB subwoofer, 2x18" woofers, behind the listening area -- also time aligned. It's works ok. But it will excite the entire house structure if you play loud -- you can be sure. Everyone will feel it. But that's not the iss...

A buddy tried for fun something that came to our mind. Extending the front. He put a quartersqare on the flat face. By that you smoothly extend and connect both mouth ends left and right. You can also use a half circle with 80cm diameter.In combinati...

Two "temporary" solutions worth considering:1) A big nasty Krell KAV 500i (stereo 2x250 into 8 Ohms; 2x500w into 4 Ohms; built-in preamp; excellent volume potentiometer; remote; holds resale value). Though the mid range and HF of Krell amps is not co...
