Post Subject: 18"Posted by anthony on: 4/25/2025
I am building subwoofers right at this moment. Have gone with a modern 18" that I've never heard and a large AB amp to power them. Will be low passed somewhere around 30Hz so I doubt that driver quality will matter... at least I hope not. This will make the system 7 ways with four bass channels including upperbass horns.
I think the quality of my bass thus far is outstanding. Truly outstanding. Soft, articulate, enveloping, powerful and all run by DSET. My direction with bass although similar in topology to yours is quite different in implementation. My room reverberation is very controlled and is very even from my lowest room mode of 30Hz all the way to 20kHz. I think this even reverb time is very important to being able to hear the room information on the recording and I am theorising that it will also help the immersive channels to function optimally. The tremendous upside to controlling room reverberation is that bass spl is so much more even throughout the entire room...modal behaviour has not been eliminated, but has been attenuated.
Over time I've been following your RI exploits and although I've not had time to duplicate them I have been planning my own multichannel audio and home theatre as well. Bills contribution seems to have been valuable to you and to be honest, from what I've been able to discern from afar, his approach gels with my tendencies. This week, a Trinnov processor arrives and once the subs are finished and final Macondo time alignments are complete I will install the last of the immersive channels to be a 9.2 system. The immersive system will have subwoofers separate to those that are part of Macondo, based on your experience (they are already built).
For expedience, I am using some active JBL monitors as inmersive channels. They use switching amplifiers and have a good sound that I think compliments Macondo, or at least do not sound overly sluggish in comparison. Ported bass of course so will have to figure out where to cross them all to the immersive subs before too much damage is done to the sound but that should be super easy to arrange with the Trinnov.
