Barefaced Bass - Ultra lightweight high power bass guitar speaker cabinets

Handmade British 1 x 12" AVD guitar loudspeaker cabinet from Barefaced Audio

We believe this is the most significant guitar cab launched since the original Marshall 4x12”. A bold claim indeed! But listening is believing - the revolutionary patent pending AVD enclosure lets you hear the true sound from the speaker, uncluttered by internal reflections or cancellations like traditional closed or open-backed cabs. And from the back of the cab the AVD does even more, filling the room with yet more natural tone.

We may have transformed the cabinet itself with our unique Barefaced Diffractor design but we refuse to discard the loudspeaker heritage that’s the basis of most great guitar sounds - electric guitars need that tonal shaping, character and vibe which comes from the inherent sonic colour of classic speaker designs. The Reformer 112 has an iconic Celestion Vintage 30 loudspeaker as standard and more cosmetic choices. And if the Vintage 30 isn’t your ideal sound, you can have any Celestion guitar 12” as a customisation, including all the Alnico and Heritage models.

This 1x12” 60W cab has as big a sound as 2x12" cabs loaded with similar speakers because the AVD uses both sides of the cone, front and back, to fill the room with tone. Despite the massive sound the weight is absolutely not massive - thanks to our unique design and construction methods this is the lightest gig-tough 12” guitar enclosure ever made!

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. 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.

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.
