Last night I did an interesting experiment. I took the bass towers, just 4 driver per side, crossed them at 90Hz, line-level and drove them not with the Milq’s bass channel but with SS Yamaha B2. I use it with the tube crossover that I used for ULF. I figure out that it has enough power and gain to drive my towers to whatever I need. I found a good flat response via RTA and sat to listen it. Good. That was juts the most revolting thing that I hear for a while.  As much as driving the towers by Milq’s LF channel made it to sound nice as much driving it by SS direct-coupled made to sound horrendous. The sound of tower juts did not communicate in any way of form with the horns and it was like 4 laser beams shooting from 4 separate locations. I never seen anything like this. The bass-wise it was enough but there was no size or space of any kind and it was just scare.  I want to stress it that it was so bad the I GOT SCARED and turned the playback off.  I did not want even to think WHY it was. It was so frightening. 
 
Might be if I add more of the driver to the towers, like 4 more then I will be able to drive it with Milq but it will be with 10 driver per side a but bulky configuration. With a dedicated midbass in the sealed boxes, no matter how not perfect it was but driving from Milq it perfectly “talks” to the horns and it gives an imagine to die for. I really would like to have a dedicated midbass. A proper midbass is to a degree what defines a high-end audio in my view and it is hard to get. Well, will see where the life will land me in my midbass journey…
 


Romy,

Have you experimented at lower volumes with running the bass array from the Milqs LF Channel at that 90Hz low pass filter?  I know you are already scratching for more volume in that room but I ask because perhaps that would shed some light in whether it was the SS amplification or the bass array itself or both that is causing the issue.  If you have nice imaging at lower volumes with the bass array in play on the Milq LF channel then it could indicate that extending the array is not out of the question.  Do you still have the extra boxes with two drivers to stack on top of the arrays?

Regards,

Anthony
