I found a couple of threads dealing with them... but I'd like some final opinions. I have a SVT-410HLF (Ported 4x10) and it has too much of a loose bottom end for me. I was looking for something "tighter" or "punchier" such the SVT-410HE (Non-ported 4x10) and I came upon the Aguilar DB series. Their cabs boast a higher sensitivity and are aimed at a vintage market... something I am all for! What are your opinions on these cabs?
