Roots and fifths and a little extra.
That's a really interesting observation. My main gig rig is a pair of GK Neo 112 cabs. I got the to replace their 115 cabs, which lacked low end. The 112s do not lack low end. However, I do run a HPF just to maximize cab efficiency. I have a bad back and I need to get top performance out of fewer speakers. I think the HPF does that. With that said, I have been very happy with the B string on my 35" BTB and my 35" EHB multi scale through this rig. I should take an inventory of what my B string puts out as a fundamental, what my HPF is at, what the "low" knob on my Super Vintage preamp is at, etc..@flyer103, if your cab is ported and is marketed as for electric bass (the usual brands we talk about here), there's a "95%" chance that it sounds bad at 31Hz, or even at 41Hz, by design (you're expected to cut that off with a HPF).
Almost no one notices this, but it disappointed and bothered me very much, and it might be what is bothering you.
If you have a USB interface you can plug the bass into and listen with headphones, that would be another way to bypass the cab.
