You bought three to come to that conclusion? And that they come in all shapes and sizes for a wide variety of uses, with the added benefit of convenience?
Personally I prefer my 4x10 cab, sometimes with additional 2x10 on top because I feel that they convey more than just a vague one note rumble.
I wouldn't necessarily go as small as a PJB cab, but I have a pair of hifi speakers that use long-throw Peerless 6.5" drivers (1/side!) to produce a very creditable -3dB point of 28Hz at sufficient volume....
So in the same vein, while my baby tuned Abarth with piddley 1.4l engine isn't quite as quick as a US muscle car in a straight line, it'll kick one up the Ariss in decent twisties!
