So, I've recently moved to flats on all my basses (all Ibbys!). My SR505 sounds fantastic! Loving the new tone! And with a slight EQ change, I've found my tonal nirvana. I've been able to play plenty loud and no negatives. The problem is my SR406. It seems to make the cab fart, even at lower volumes. I'm thinking it must be the flats, since I know that this is the only difference (I run them both on the same EQ, and let the basses' natural qualities make any differences). With some minor EQ changes, I got it under control, but I was just wondering if you guys could share any tips/info.
For more specifics, I am using RB heads (700 and 400). The note that is most prominently farting is the open E. Was it terrible? No, but it definitely didn't sound good. Not smooth at all. Nobod I used to have the woofer maxed. That's been one thing that has been consistent with all my EQ choices on my rig/s. My EQ is lows at 10:00, hi mids at 2-3:00, low mids at 11:00, and bass at 1-2:00. I'm getting an Fdeck Series 3 soon (just ordered it last night!) to function mostly as protection for my cabs. I've been thinking of getting one for months, well before this problem started.
