Here's what Barefaced Audio say about the Radical 212H:
The all-new Radical 212H is the ultimate cab for gigging your big valve amp head. With the unique AVD+ enclosure you don’t need to use a 4x12” cab to get that full power large scale sound, be it for rock, blues, funk, metal, anything - even the loudest bluegrass band on the planet.
If you haven’t heard a Barefaced Diffractor guitar cab you may be sceptical that something this small and light can sound as big and heavy as a 412 - or that it’ll cut through on stage without being as tall. This is where the science comes in:
The AVD+ enclosure uses both sides of the cone to generate sonic output, doubling its acoustic power and dispersing that sound everywhere around the room. No longer will you have to lurk in that narrow cone of tone and finally you’ll be able to consistently get that Goldilocks mix, not too loud, not too quiet, just right - both on stage and in the audience. Gigs are better when you all hear the music as it’s meant to be!
As standard it’s loaded with two Celestion Vintage 30 loudspeakers, giving 120W power handling and buckets of authentic tone.
What is AVD+?
You see it when you look at the back of the cab - it’s the Augmented Vent Diffractor. It’s a unique Patent Pending technology that we started developing back in 2013. At low frequencies it acts as a tuned vent or Helmholtz resonator, improving efficiency, power handling and output. At mid and high frequencies it acts to diffract, disperse and couple the sound with the room for improved audibility and output especially in rooms with poor acoustics.
From the front it behaves much like a closed or open-backed cab. But the mids and highs coming out of the AVD+ at the back are amplified and dispersed around the room whilst the lows are inverted to match the lows from the front, giving lots more bottom. Basically you get twice the output of a closed back cab with an identical speaker AND even better dispersion and audibility (and far far greater output) than an open-backed cab.
What is the Lo Cut filter for?
The increased low frequency output from the AVD+ may be too much for some guitarists’ tastes - so you can flick this switch and remove lows at the cab. Doing so not only changes the bass response but also increases the power handling of the cab, lowers the distortion due to motor excursion and reduces the load on your amp’s output stage. This can give you two different sweet-spots of optimum speaker overdrive or break-up and two different sweet-spots of power valve overdrive. If your sound is perfect in rehearsal but too dirty at a louder gig then engaging the Lo Cut filer will clean it up.
