I have built a large cabinet according to londonpower (Canada) specs. They call those cabinets "detuned" as opposed to a "tuned" (ported) approach. It is kind of an "open front" cabinet without the drawbacks of an open back cabinet.
Those cabinets sound terrific but are somewhat clumsy.
Behold it on my web pages. You can see the slots through the front grille. There is no sound files, because those would only make sense in direct comparison with something. Besides that, it would not help for directionality tests. It has killer tone for steel with a single 12" Eminence deltapro-12a but also for guitar, harmonica and even bass.
For better portability, I am currently building a 1x10 detuned cabinet, which is half the size of above, teamed with an ultra-low noise mosfet amp and versatile loop section.
To cut it short, all cabinets beam. The bigger the cabinet, the more it beams according to londonpower. Acoustical lenses like slots or even the beam blocker help a lot.
