My greatest memories are playing in orchestras and sitting in the middle of the violin section with a hundred other players on stage creating music and being completely engrossed by sound. It's magical. That is what I am starving for in my playback system. My system has been organically growing the past two years. The first "ah-ha" moment was vinyl, then tubes and now horns. So I think (I hope!) I am on the right path. |

I do not want to disappoint you but I do not think that anything that you do in audio would able give you the captivation and attention you get from live sound. If you think that I would be able to pitch to you some kind of cable elevator, speaker topology of tube brand that would do that magic switch then you are mistaken. I think you mislead yourself by expecting this from Audio. Audio is very interesting and much more complicated tool then most of audio people understand. Audio is not about re-experiencing but rather about re-conceiving. It is a big subject and I do not want to go into it here. If I were you and I would embark in many years and thousand dollars project then I would like to see if any light in the end of tonal. Did you hear any horn inhalation that you like? Did you feel that the audio result that you have heard did deliver to you that state of engrossment that you would like to pursuit? If you feel that my inhalation shall do it then spend a fraction of cost that your project will be, fly over and listen yourself. It is possible that you would not find it not worth to be bothered or the efforts that need to be spent is not reasonable.

And I want to position the VC of the tweeter in line with the midrange. I'll plan on putting some foam on the underside of the horn and on the top of the woofer cabinet to absorb some reflections from the tweeter to these surfaces. |

Yes, the arranging of the channels is important but from how I see it now if I do not have any playback and my objective were to have one then I would first start from space analyses. I am not taking about running RTA in the room and figure out what and what is not good but I rather to look at the room from a holistic perspective and decide what kind of acoustic system the room would be able to accommodate and what kind acoustic system topology would be the most beneficial in the given room.

Agree with you about this channel being the foundation of the playback system. Could my JBL 2226 work for this? Or should I consider another driver. You use the Fane Studio 8m for this purpose…. |

The selection of a driver is irrelevant in my view. You need to conceptualize what kind of acoustic system you would like to have. If, again if, you decided to have something Macondo-like then you ruled by the uppperbass’ throat. I went for 4” and it was very strategic decision. In Macondo configuration you would hardly be able to accommodate a horn larger then 140”. The 140” is 110Hz to 150Hz, depend of the room, projected to 4” fast opening throat it is about 6dB equalization at bottom knee. The smaller throat is longer horn, more equalization and slightly different sound. The same with the larger throat – size and sound will be consequences. Plus there are consideration of attractiveness and finicality… I would start thinking about uppperbass first….
