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...

Romy,You make very, very good points now I am re-evaluating this all-in-one horn concept. I do know one thing that I learned from my current system. Midbass horn that rolls off below 120 hz and integrated with sub is not good. I have struggled with t...

I am just reminded of the long-since-superceded (naturally...) 10" Tannoy "mid-field" "pro" monitor. I think it was the TM10, which also used it's cabinet to very good effect, at least in terms of voicing. You want "bubbles", I...

Unluckily I have no experience with IB, would love to. Any way If you want it hidden and time aligned, the best bet is the uderground!Now having all that space there it would be a pity not to go IB.The IB idea can be much more elegant than the pic...

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...

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...

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...

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

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...

[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...

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 ...

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

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...

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 ...
