[quote user="haralanov"]I think you wanted to say reflection surface, not radiation surface, right? Radiation surface is the surface that is directly attached to the vibration creating element (the voice coil). So the radiation surface of the horns u...

[quote user="Kcct82"]Thanks Romy, your comment above cleared some of the questions I had regarding 50/60hz midbass horns.
I found some info on the driver after digging through Japanese sites. I don't know if these info will help interpret with...

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 ...

[quote user="rickmcinnis"]I would worry that there could be an interaction between your electrical filters and the filter formed by the horns themselves.I, too, like to trust my ears and I would ten to trust yours more than mine but nonetheless you h...

Danvprod, I hope you understand that “proper four or five-way system” is some kind of Unicornnish type of animal and we could talk about it only abstractly. Still, since you have mentioned it – what and how are you trying to accomplish with your five...

user="jeff1225"]Romy,When you say that the Vitavox 15" was the

for them. [/quote]

Again, none of the pneumatic methods would work as any pneumatic leak air with time and it will be no access to it after the horns are installed and the walls are finished. Not mention that we have no high to play wit. We will be doing the follo...

Similar to the famous sexist tail that women can be only ether pretty or smart the midbass horns unfortunately behave in the very same way: they can be only nicely placed in a room or they can sound good. You want the horn to place in a specific ...

Lately I have been thinking a lot, trying figure out what I
am and where I would like to go with Macondo. The Macondo base, the horns isle
is still there and I have no motivation to change anything. The conceptualizing

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...

[quote user="Romy the Cat"]I do not understand what does it mean. Are you saying
that you lost bottom response with closed exit hole on the driver back? If with
the closed drift from back you have a (loaded!) response no lower than 200Hz then it i...

I had today a long listening session. I listened a whole Mahler Second and I can tell you that I was the best upperbass I ever heard from a playback. I am not kidding. The upperbass literally despaired in the new room but what it is being called up...

Somebody in this there warned me that the fiberglass pipe wall finishing that I employed on the wall with my midbass horn, behind my listening location might be environmentally not healthy. I have very high sensitivity to fiberglass and one singl...

Murat,
I was looking at your midbass horn design and I am wondering, how are you planning to time align that long midbass with the rest of the channels that seem to be time aligned. I mean, currently the midbass is physically 4.3m behind all o...

[quote user="noviygera"]1. Let's say
the my original back chamber from the manufacturer is a good "starting

While the aftermath of the midbass horn project is not over I am strategizing how I might implement Macondo’s LF section. The leading idea is to bolt a triangular shape sealed enclosure juts behind the small wall that cover the load bearing beam from...

romy, you said, you would place a 60hz midbass on the side, is this still your opinion? of, course i found no other solution in my small room. will do it the way you suggested, 60-300, 300-1000(thinking about gpa 288h(s2 is too expensive for me), may...

[quote user="Wojtek"]You mentioned it yourself that the most interesting midbass you ever heard was from corner horns. Why not utilize if you can a pair of K-horns (or clones) bass (midbass really) bins with sort of moveable fake corners? They can be...

I do not do anything with my Opera Room, and I am not sure if I will. Still, from time to time I pick from the tree of possibilities some very kinky fruits. My love to Mussurgsky is know and last weekend I visited my local audio guy who has a very go...

The mean KOTriode in his thread “A different breed of 6C33C amplifier“ jinxed me with his 6C33C vulnerability and today my output tube at right midbass channel went down. The characteristic pings, which via the midbass horn sound like house room is c...

Tubebuilder, I am not sure what you are trying to do. According to the “Romy’s Rules” (whatever it means) people do not build Midbass horns but they build an installation that might include the Mid Bass horns. You do not need to choose a project jus...
