In my first design, I kept them all in a vertical line. It had one channel less back then. When I added the 1" throat JMLC 1000, I decided, as the tweeter operates over 9.6k, the slight misalignment may not matter. Still, I kept vary and kept the fra...

Kodomo, what is your ear height when you are sitting in your listening chair? I guess it is less than 120cm. Perhaps when you finish setting up the horns and remove the wheels effectively lowering them you may be in the position of lowering the twee...

I am trying to keep the discussion about midbass horns out of ULF thread, I guess if Rakesh would like he can create a separate thread dedicated to his specific installation and the design ideas. I would like to keep the content of the posts more...

[quote user="Romy the Cat"]OK, I disconnected my MiniMe speakers and left only Macondo to care sound in the room. I was listing for the last week Macondo. There is no bass, just upperbass horn at the bottom and The Injection channel a full range....

OK, guys, thanks for your help.
It looks as I made it eventually to sound better. I increased the loading impedance to 90R (which hardly means anything, still can't figure out hoe much the Ortofon what to have it. They say 47K, which probably...

Ok, now it is done and it is official as I see nothing available for conceptual improvement in the crossover circuit. Interestingly this version offers the most interesting sound as well, since the circus was tune for sound, not vise-versa, it is wha...

[quote user="Romy the Cat"]Now it will not be the midbass horn. [/quote]I think you have found phenomenally good sounding upper bass driver and you are going to build a dedicated quasi-bassreflex channel using it to fill the gap between your line arr...

[quote user="Romy the Cat"] A few years back I wrote somewhere that I “developed” a semi-mathematical formula according to which an acoustic system’s result might be absolutely objectively weighed up. I did not go very far with advisement of this eq...

Ok, how to start. First of all we have to understand that out subject of attention will be a region between approximately 80Hz and 500Hz or something that shape the fundamentals of the “melody range” within your playback. Search my site I have writte...

First upperbass horn is up and running. Second one is now on the lathe with hopefully a quick turnaround. Now I have to figure out how best to tune it...

[quote user="Romy the Cat"] I guess your definition of “doing something different” would imply reading of 534 pages of BS from people who have no idea about Sound about advantages of LA-horn over tractrix… [/quote]Touché! Now you are referring to my ...

[quote user="jessie.dazzle"]….. sit back and conclude that, yes, damn it, a pair of good straight Mid-Bass horns is exactly what you need. My reasons are of course somewhat selfish... as I won't like being alone in needing a non-digital delay solutio...

The AA Moron in response to my criticism give a birth something interpretable. Here are the sweeps from Upperbass Horns and MF horn. I have no knowledge if the Moron removed the filters or the EQ circuits that might be used, wich sweeps he used...

[quote user="T3GGG"]Romy, what is your thought on using a Tractrix flare on a Midbass horn, Fc 140HZ then maybe a Le Cleah horn above, say 400hz. To me this looks on paper to be the best of both worlds and avoids the 1metre plus midbass Le Cleac'h ho...

None of the commercial speakers might relay on the Imbedded principles because the obvious reasons. They always look for as neutral as possible location because they mostly designed for anechoic operation. However, if the Imbedded techniques are used...

Jorge, if you have 120hz horn with a 4" throat and 10" driver then Fane 8M would be a good candidate in my view. If I were you then I would try. The SG146LG is you had would be very interesting to try as well. Not to try it stupidly as most of Go...

This week I will be trying to address why the Milq midbass is clipping. This is very interesting one. Currently the Melquiades LF channel uses an output transformer 700R to 5R or 11.83 to 1. I thought before that I have much lower ratio, like 5:1 bu...

Keith,
you see, in Alphas the MF driver does down to let say even 500Hz then it mans that they need to bring those bass W-bins unto 500Hz but it is imposable even theoretically. Let me to expanse, it I very simple. When a “reflected” horn fires up a...

Finally, it has happened. Sound. Two weeks ago I had a couple of mates help me carry up and install the first DSET on its pedestal on the horn stack. It was quite a bit of effort and three were definitely required for the heavy but delicate operat...

Haralanov, I partially know what you are talking about and I got my sense of it when I added the Fundamentals and Insertion channels. They both are position above MF and act as nice compliment to Macondo upperbass horn. I still do not know if the...

Maybe, some people would be interested in what I am doing with my system. I have been continuously listening and sparsely making changes and letting them sink in. For now, I feel more settled and think the biggest obstacle for me in reaching the ...

[quote user="skushino"] Edgarhorns weren't an obvious choice. Many horns never worked for me. The Avantgardes left me cold. So did the single-driver crowd (I just don't get it....), Altec VOTs, PA systems, etc. But there were some systems th...
