Hm, the Injection channel via Lecleach? The MF via Lecleach? I wonder why people then are complaining about the vertical limitations. Anyhow, closer to the point.

| I have spent hours coming up with all sorts of weird and wonderful, but at other times too rigid systems to support the various components comprising what I modestly choose to call Le Horn (AKA Rakeshorns). I have more or less decided on the final design but would like some thoughts on the issue of positioning the MF channel (400Hz tractrix - possibly 550Hz tractrix or 550 Lecleach after experimenting) with respect to the Upperbass channel and the tweeter in the vertical plane. My initial view was that I needed to leave about 5cm between MF (Vitavox S2) and my 96cm diameter UB115 horns and similarly between the MF and the ribbon tweeter (Lazy ribbon from Raal initially). I was prepared to leave a certain amount of overlap between tweeter and Injection channel (250Hz tractrix - possibly 320Hz Lecleach, if I decide to include this).
However, my latest view is that I need to reduce these vertical distances to the bare minimum and I am considering to have the UB115 and MF channels with no vertical gap whatsoever and likewise between MF and Raal tweeter, and have the Injection channel so low it covers upper part of Raal Lazy ribbon by 2-3 cm. The main constraint is that although the ceiling height is approximetely 235cm, there is a 40cm thick beam going across the room in front of the area where I want to position the horns which leave a floor to beam height of 190-195cm. The frame I have designed (not yet built) gives me a fair amount of adjustability but it would be great if I could position the supports more or less where they will end up being eventually. Any thoughts anyone?
If I were you then I would not do what you are doing now – I mean to design frame. I know it sounds odd – I am advocating thinking about frame but at the same time I am persuading do not make frame. Ironically there is no conflict in it and if to look deeper then I see a lot of rational in my position.
What kind frame a person can come up with if he does not know what configuration of playback he will end up with? Yes, you can make the very flexible frame that can accommodate many setting buy why do you need a flexible frame if in the end the frame will care only one final configuration? The specific and non- flexible frame will be better anyhow, I hope we all agree with it…
Also, it is about a lifestyle. I do not know in what British castle you live but my experience with all folks who go for large multi-sell, including my own, indicate that soon of later they all move to larger listening rooms. I think it is some kind of virus….
So, I would advise to not be in hurry. Build the bone – the MF and Upperbass. Do not do any tweeters or and any ridicules Injection channel. Put your MF and Upperbass “on the books”, ad some LF and play them as is for a few months. Set the crossovers, find an amp that you like, discover Bruckner, get married and bring your company to public offering. Then play with tweeters while your pregnant wife is searching for new a house where your new twins and your new horns would live in peace and harmony. Then, having a larger room with having own experience, own expectation and own reference (instead of following the idiots online) your will compliment your playback with right final frame and with the rest channels that you might or might not find necessary.
Rakesh, I know that internet audio people are looking for specific recommendations formed in inchers, decibels and brands. I assure you that audio is not only about technologies but also about self-discovery of moments of realization. From what I know about audio the upperbass channel and MF channel that you looks like will built will be phenomenal music exploration devises, good enough to last most likely to the rest of your life. The rest that audio that you plan I think will be variable. I do understand that you have a tendency to get all together right the way. You most likely not a teenager, so tell me how much “all together right the way” have worked in other aspect of your life?
