It uses at the buttom a regular sealed or ported box and the driver as direct radiator but they also put the speaker on the spikes and made the bottom looks like it is a horn output. Also at this larger model[/quote]On the smalle...

[quote user="Henry"]I've heard these Haniwa speakers on Sunday. They sounded terrible. My niece and her boyfriend went on Friday and couldn't get Kubo to play something other than classical music. When playing classical music, the sound was...

Herman,
I am not familiar with your driver and I do not know those horns. It looks like they are 200Hz horns through….
You shall not worry about your horns create any shadow. As I understand you use digital crossovers with your horns and if...

Chris, yes and no. The phase shift 90 degree of there perhaps but it is not really relevant. If we have a very low frequency horn, crossed low with high order crossover and the entire horn is delayed at 30ms then we do not have the same negative impa...

[quote user="Wojtek"] Roman, could you (or enybody ) elaborate a little bit on JBL L8 and its application ? Not so much sensible info on the net besides that its a fullrange usefull in 40Hz-8kHz. [/quote]I do not know, how can I elaborate if I never ...

As late as the 1960s every self-respecting hi-fi nut had a "secret recipe" for "speaker dope". My own guru would not give me his exact recipe for speaker dope but insisted that developing the stuff was a rite of passage I had to go th...

Last month of two I keep thinking about the super-meaning of lowest octave in sound reproduction. It is not about the importance of the lowest octave for sake of audio reproduction, there is a lot about it in other pleases of my site and anywhe...

Ok, Scot and I spent another day to mingle with my new
listening room. We hang some acoustic treatment and brutally covers large windows
with blankets. The room become more pleasurable. I have placed an order for extra
pair of drivers into my bass...

For the person who very easy toss comments like “utter nonsense”, BS and “does not make sense” you are very uninformed. If you stop position yourself as an ignorant teenager who “knows everything” then you have chance to learn something. The Car Talk...

Romy,I might have overlooked something on your site but I understand that your ULF amp is driven directly by the preamp line stage. If that is the case, you may want to consider an old technique for integrating subwoofers and drive your ULF amp w...

Haralanov, I do not think that the “information” that you found is indicative of anything. If they changed coils and diaphragms on their LOMO drivers (and I presume that if they change the diaphragms then they did not keep the LOMO original suspensio...

It is so funny. As Kitty and I are looking for different
houses we look at different listening rooms and we have different ways to think
about room sizes. She think about space for her piano and size of oriental ran
she would drop on the floor. Wh...

Oh, rowuk, you have no idea how much I agree. To me passive theaters very much like ports and I hated anything which stay even remotely close to it. However, this time the entire Remedios project is is very different s s is built not based upon knowl...

Come ooon,
comparison between the radiating area of direct radiator vs. the area of horn’s
mouth is too amateurish even for some diyaudio.com level simpletons…
It is as naïve
as saying Leonardo’s Mona Lisa is simply 100 grams of paint splashed ...

Actually, when the string section has to play ultra softly, they use a mute or damper on the bridge. This is a device that limits the ability of the bridge to pass the string vibration to the resonant body of the instrument. http://www.youtube.com/wa...

[quote user="haralanov"] Romy, the actual sound benefit of this 4-channel upper bass configuration, is rather in the type of sound presentation. The commonly used single upper bass horn (or direct radiator) sitting under the midrange horn, gives the ...

Mani, sorry, but I forget if you mentioned very specific size limitations. I have enjoyed in spates but am generally wary of "big sound from small boxes", as this invariably wears thin, eventually requiring not only a tiring stretch of the imaginati...

hey romy and all-i recently came across a strange phenomenon (to me.. maybe not to everyone else!).I just started using RTA as a method of evaluating my results with my own 2 way speaker system, and I'm finding that I'm ending up liking the sound of ...

Actually, I very much disagree.
Whatever “people working on this around the world” … they work on very irrelevant directions. I did not see from ANYONE in the horn universe any more or less serious attempts or serious intentions to combine the bene...

Bud, the replacement diaphragms are available all time. On Ebay and everywhere else they are being sold by Bob Crites. He holds the original manufacturing rig and he can do them in unlimited quandaries. I own the original diaphragms but I do not use ...

Haralanov, as far as I know, Madisound does not offer my ribbon. Mine is not a stock Fountek, but it is a re-worked version of the old, discontinued Fountek JP2, a very narrow "naked" ribbon (ie,. no coating), and 97+ dB efficient. I got my Audaphon ...

Amir, Romy was actually very specific about why he was critical of Melquiades/Macondo. Even in old posting, he made a point of mentioning that he very much knew what weaknesses he had. To be honest, I believe that his real motivations for change are ...

Hm, I like the Cessaro thinking a few years back and I love it now. A very good move with this “Liszt” loudspeakers, even I am against the idiotic tendency to grand to the audio element the composers names. Take a look what Cessaro did. A tweeter, p...

I'm of the opinion that listening room aesthetics play a big role in enjoying music at home. This is self-evident, but over the many years playing with audio, my listening room has become incrementally cluttered with "audio detritus". It's ugly and...

I never seen the polyethylene drivers but I would not say that it would be a joke, I would rather say that I have no idea what to expect. The SL600 MF driver is a polyethylene-like driver and it does have some interesting qualities, Sure it you drive...
