Back to 2006 I had a thread “Adding one more spherical to Macondo.” The thread itself and the concept that it lead to - the Fundamentals Channel - turned to be a phenomenal success. I know, I know for someone it might appear like nothing but if you do run your playback with a dedicated, active Fundamentals Channel and you have option to dial it precisely to the rest of your Sound then you know the power.

My current Fundamentals Channel is 600 to 1000Hz in 250Hz tractrix driver by Vitavox S3 driver with old metal diaphragm. I however would like to run it from 300-400Hz but ether driver or horn did not allow me. So, I always would like to have larger horn, just a bit sub 200Hz and then to find a driver that would support lower crossover point and will furnish the sound quality that I would accept.

I however can’t not go for larger horn as I do not want to minimize clearness for tweeter and Injective channels. I also would like do not use tractrix for my Fundamentals Channel but to go for exponential profile and to drive it harder down. This all lead me to the idea that I need to go for rectangular profile with fixed height and to add opening on the side. The multi-cell architecture was a logical chose.  A regular 15 cell with my targeted height usually do 230Hz but I have unlimited width. So if I find somebody who can curve the thing to 18 or 21 cell then it might do.

I found a guy in England who agreed to do the 15 cell, 183Hz horn with 1.5” throat. The requirements’ were to have them made from soft wood, fill-able with sand and a few other things. The horns are semi-done, sitting in the room and ready to be tested. 

I am not diving in this project right now as I would like to wait a bit. I would like to beef up those multicells . I would like to think how I would mount it to the Macondo frame, How to finish them. The most important I would like to see if Macondo will be truly beneficial from this type addition: sonically, visually, ets… I never was multicells fun but Fundamentals Channel does not do any HF, so it might work. I initiated this thread and I will with time to post my observations about the use and accommodation of this new multicell. If everything tune well then I will add to Macondo but I at this point not wind about visual aspect.  The   multicells looks too much like loudspeakers. I might cover the multicells mouth with black caustic fabric or perhaps I will get softer on it after I paint them black…. I do not know, let see what will happen.
