Revisiting earlier threads on "sealed vs ported" I found this from Ukiah Bass, which totally right on. When I first started playing bass 40 years ago, I spent all my time tying to cop the sounds I heard on albums with my POS amps. But as I've grown older, and hopefully wiser, I realized that what I was listening to was heavily studio processed in ways that I would never be able to accurately reproduce live. Just the mastering technique of banded compression would mean I would NEVER sound like that.
Ultimately I settled on the phrase "how does my sound make me feel?" When I am in front of a SVT refrigerator, I feel the power on my backside, which in turn makes me play with more oomph mentally, when I play through an Epifani 410 I feel it too. One is sealed, one is ported, but the feeling is the same. So now I don't worry about the "sealed vs ported" issue anymore. If my live sound makes me feel like I do when I hear Chris Squire or Nick Jameson or Duck Dunn, it don't matter what I'm using in the chain: bass, effects, amp or especially cabs!
