First Steve W, then Tang, now me.
I mean turning off my subs. I'm not 100% convinced I won't go back, but I'm not majorly missing them. And FWIW, the upsides are considerable atm.
So Steve and Tang, it's catching.
Marc,
Sorry to spoil you fun, but after optimum placement and much experimentation with port positioning the XLF's had great bass and I could perfectly survive without subs. But when I added a pair of JLAudio F113v2 with the CR-1 controller the overall performance improved. I should stress that I found the CR-1 controller fundamental in the set - up. I never managed to integrate just the subs with the integrated filters without it.
BTW, I could only tune the sub using a few initial measurements - otherwise just listening would drive me in wrong direction. Initial setup is too dependent on specific recordings to be carried by listening.
BTW2 - I am not a patient man for audio. I can not consider carrying months or years to fine tune something. After two or three weeks I give up if it does not persuade me! And I want to go on listening and to have fun doing it ...
BTW3 - the answer depends a lot on the music we mainly listen. I would not need subs to listen to rock or country music.
