Unbelievable idiot!

Last night an audio guy visited me and I played to him some music. I was not sitting in the listening spot but what stroked me was now stringent and how shallow the playback sounded. I was waling around the listening room, scratching my back a wondering what the hell is going on. The electricity is great recently but sound is not elegant as I am accustomed to. Listening more and more I suddenly realized that I do not have my bass. I have my soft and nice midbass but I did not have my last exhale of Macondo that I am so proud off. Then to my shame I realized that that meters on my ULF power amp are not moving.  Reaching back and tracing the cables I learned that the ULF crossover was just disconnected. A month  or two back, when I connected the small Pilot speakers with own amps I did not have empty output on my preamp and I unplugged the ULF crossover to use the  Pilots. So, I do not use ULF for good tow months.

Putting back the ULF was like coming back home. The long decay of my midbass does not sound so horrible anymore, apparently the ULF, kicking at 20Hz does moderated the midbass decay. I still feel that there is a very very minor midbass decay issue but it no nears close to what I am experienced lately.

The playback again sound spectacularly and the re-charging of the drivers project is  not at my radar anymore.


I need to look further into the midbass and ULF interaction as it is very interesting subject.
