Barefaced Bass - Ultra lightweight high power bass guitar speaker cabinets

Handmade British 2 x 12" AVD+ guitar loudspeaker cabinet from Barefaced Audio

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. But if your sonic preference differs, you can customise it with any Celestion 12” guitar driver, we offer the whole range.

There are basically two sorts - closed-back and open-backed. Open-backed because they were combos and needed to keep the valves cool and accessible for servicing, closed-back and sealed because that’s how most speakers were made in the 1960s.

The closed-back cabs have narrowing dispersion as frequency increases (a hi-fi speaker uses smaller speakers for higher frequencies to reduce this problem). The open-backed cabs fire sound out of the back as well as the front, so although the dispersion narrows from both front and back in much the same way as the closed-back cab, the sound coming out of the back helps fill the room with mids and highs - but that sound out of the back cancels out most of the lows (due to the inverted phase as the back of the speaker pulls when the front pushes and vice versa). In other words, open-back cabs are easier to hear around the room but the lows are thinner.

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.

You see it when you look at the back of the cab - it’s the Augmented Vent Diffractor plus the secondary tuned reflex port. It’s a unique Patent Pending technology that we started developing back in 2013. At low frequencies the AVD and the separate tube port act as tuned vents or Helmholtz resonators, improving efficiency, power handling and output. At mid and high frequencies the AVD acts to diffract, disperse and couple the sound with the room for improved audibility and output especially in rooms with poor acoustics.

The reasons for the AVD+ design on the Radical 212H are twofold - for maximum horizontal dispersion we only want the mids and highs coming from the back of one speaker, so the sound source is narrow compared to the wavelengths - that's why there isn't an AVD behind both 12" drivers. But with just one AVD the cab ends up with too a low a tuning frequency to be optimum for guitar, so we add the secondary port to raise the Helmholtz resonance. At low frequencies both the 12" speakers drive the AVD and the secondary port, it isn't a split enclosure, there is just one air space and tuning frequency.

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 filter will clean it up.
