He cruised around audio forum (ordinary suspect), brainlessly buying anything imaginable, was posting very regularly his “audio progress” at many forums and in my estimation did not end up with anything sensible. His infatuation with horns was over very fast his interest in music always had been pathetic. At this point he should be moving to accumulate golf cards, evaluate Thailand escort services of collecting postal stamps (as most of his cultural peers do). Murat was different, he decided to be Audio manufacture, sort of to follow the step of the celebrated audio-idiot  who defected all over audio internet with this “copy-paste thinking”.    Russians had for themselves some kind of audio should recently and Murat presented his System 911 product. It is wide-range driver AER BD4 with direct radiator with active amplification. I know or care very little about the System 911, my experience with audio/life suggest that if I know how person thinks than his creative output is very predictable, so I will not waste my time to analyze the Mural new speaker – it should be waste. Still, there is one very remarkable thing that very positively hit me in his design: a transparent horn.    I have no idea what the material it was made and what sonic quality it has. I also very much oppose the profile of the horn the System 911 use. I remember Murat was stupidly crying that only la-horn able to produce proper sound, I think he forgot his cry…. Still, the notion of a transparent horn I found to be a VERY positive direction, I wish we had good materials to do it. Horns are notoriously large and visuals might be destructive. Using visual transparence and proper frame design it is possible to make horns to have very little visual footprint. In his System 911 Mural capitalize the transparency benefits very effectively and I would be welcome to see more experiment in the transparency direction.

Acrylic would be optimal, vacuum formed at elevated temperature. Were Jessie dazzle still here I am sure he could whip something up in no time...

What I suddenly got attracted is not to the transparency of horns but the transparency as a concept. Let me to explain. All my audio live I had an eversion to what I call “chrome bumpers”. The chrome bumpers are fine finished or high color audio elements that made to be attractive. When I see high colored horns, high gloss amplifiers or manufactures who charge premium prices because R and L speakers have symmetrical wood grain I want to vomit. These barbaric “audio attractiveness” objectives are light miles way from what I feel important in audio. I do not deny healthy pursue in aesthetic including in Audio but for whatever reasons the “chrome bumpers” in audio made me very uncomfortable. Perhaps it is because I seen too many people in audio who keep polish their chrome bumpers and musical did not developer themselves further than a few audio test disks…    Anyhow, for me the visual absence of playback is very important factor. I have a tendency to have everything back, tend to listen in dark and to get the things best I very frequently close my eyes. There is a twist in all of it. If hypothetically to presume that the entire playback is visual transparent or closed to be transparent then it opens a pandora box for very different type of playback/room interaction in case the installation is large and elaborate. I always had a fantasy to have a playback installation made in a shape of garden where audio elements are intermingled with garden elements. I think with transparent horns this might be done in very interesting ways. "I wish I could score everything for horns." - Richard Wagner.

Yep, it looks like the transparent horn is not Murat invention but AER invention and Mural just adopted it.  It does not change anything. I feel that idea is very interesting and I reals would like to see somebody to some ambition installation using the transparency as a design element.  I do not know why but really see it as some kind of sound radiating forest side of the room with Liana vines all over the transparent horns. Or perhaps the horns need to be made from bricks. I am known sucker for red bricks houses with green ivy… "I wish I could score everything for horns." - Richard Wagner.
