How low can Barefaced guitar cabs go? AVD answers!

[@Gyllbonus]

I love your shows...it's like having a live academy...kind of like the bluguitar show mega interesting concepts.

[@ivonsmith4255]

I’m still (after delivery to malaysia several weeks ago) crazy excited by having my 1x12 Reformer Gtr cab! It’s perfect and brilliant and loud and clear as a bell but warm. These things are beautiful and light weight. Love mine!

[@Colin_Wait]

Deep speaker geekery! Fabulous, thanks Alex!

[@Factless_Wonder]

I came for the nerd talk. Left fulfilled.

[@vitoleo7197]

great talk, very interesting. Hope to buy one of your cabs one of these days. As a Physicist (not knowledgeable in acoustics though...) I really liked the explanations.

[@ivonsmith4255]

Alex you’re a very clever guy! But you explain it well. And the fact that you even bother to try n educate us public ppl speaks volumes about your passion and science driven belie in Barefaced gear. That reassuring. Keep up the lectures when you can. I’d love for ypur company to be able to spread this knowledge then Barefaced can around the world. As much as you want to handle!!

[@PooNinja]

He explains the how and the why. I believe your correct, it’s called passion 🤘🏽

[@BarefacedAudio]

Thank you, I'm glad I'm making sense!

[@amoontube]

Maybe some example sounds? Helmholtz resonance next 🙂

How low do ya really need, my recording HP is a pretty steep drop below 100hz. But I do enjoy the big bass bloom of an big palm muted strum and release chord. But onstage or on tape that stuff just muddies up the mix. Those Freqz are for the bass n drums to occupy. Beautiful breakdown Sir

[@voxpathfinder15r]

It’s interesting how theoretically open back cabinets response in the low end drops off dramatically. Yet my Princeton chorus 210 amplifier with the eminence legend 1058 speakers in open back has a huge amount of lows. And so does my Carvin 212 open back cabinet with the eminence GT12 speakers. Heck even my Vox Pathfinder 15R amplifiers deliver tons of bass from 8” speakers. All open back or perhaps more correctly called semi open back?

[@IsaacJDean]

I’d love to see what a 4x12 from you would be like, even just a prototype. I play extremely downtuned and extremely loud doom/drone so more SPL and lows the better 😬

[@TimpBizkit]

Well 4 speakers in a 4 x 12 in a square pattern make the cab very directional in the upper mids as you move around the cab, so putting 2 12" vertical is better and filtering out all but the bass and lower midrange from one column of drivers.

[@Emily_M81]

It actually made sense to me. Thanks for sharing! I'm kinda surprised guitarists downtuning into the basement don't just use bass drivers already XD or guitar speakers/cabs designed for it (some are going FRFR with their modelers, at least... but then using Celestion IRs lol...). Tbh, as primarily a bass player, I've always played guitars through my bass amps and speakers anyway, and I'll probably continue to do so. And out there, somewhere, a guitarist using a 4x12 with Vintage 30s is just waiting to tell me not to or why it's a Bad Idea.

[@BarefacedAudio]

We've got some guitarists using our bass cabs, like Buzz from Melvins using a pair of Super Twins. Great for HEAVY tones.

[@tonekilltech]

Thanks for more great content! Does engaging the low cut switch increase the efficiency of the speaker since its not working as hard to reproduce the lowest frequencies? Or more specifically, does more efficiently turn amp power into perceived loudness?

[@BarefacedAudio]

It reduces current flow through the speaker and current demands on the amps.

[@mattfleming2287]

Love the science! Finally, someone is explaining what the difference is in closed back vs. AVD and open back...I find this stuff fascinating. Completely unrelated question. There are 2 jacks on the back of my Radical cab-could you use both at the same time from 2 different heads? If not, why 2 jacks? Just curious. BTW, I've had the Radical for a while and it's amazing. I love the sound, the volume and the light weight. Best sounding cab I've ever played thru. You guys are awesome.

[@BarefacedAudio]

DO NOT USE TWO AMPS INTO ONE CAB (unless it's some kind of special cab that's actually two separate cabs in one box). Explanation about two jacks on a few of the other videos, like the low cut filter video I just put up. Glad you're loving the cab!

[@mattfleming2287]

@@BarefacedAudio I saw that video, thanks! Great info, btw. This is a level of acoustic science I have only briefly touched on....where were you in the 90s?!? Love the vids-it's awesome to get that much info about all the science behind the noise

[@yowild9629]

have you consider isobaric construction cone to back ?

[@BarefacedAudio]

I think I made a video about isobaric cabs a while back - it’s an interesting topic but 99.999% of the time they’re a bad idea from an engineering and sonic standpoint but I can’t deny that from a marketing standpoint they seem appealing.

[@yowild9629]

@@BarefacedAudio no sub style . but cone to back . i built one … sonic diference . more presence and mids & posibility to make it 4ohm or 16ohm . unconect one and 8ohm . using that unconected as passive radiator . more bass & conect to ligths or some resistor to lover the bass or send it to or use it as microphone … lol 00.01% good idea?

[@BarefacedAudio]

@@yowild9629 there’s a lot of strange stuff going on with a design like that - if it sounds good to you then cool. But part of what you’re hearing is similar to running a short single repeat delay with some EQ on that signal, which represents how the rear cone fires through the front cone.

@@BarefacedAudio phaze realation called Reactive wats you need to consider PETEROVOLTAICS FARADAY its like a transistor stress crystal that amplify mono to stereo and cancel background noise utilising wasted energy by volts being in faze with current consider eric p dollard flame speaker ;)

[@gcvrsa]

10 dB is not a doubling or halving of loudness. I don't know why this old saw keeps getting repeated. By mathematical definition, 6 dB is double or half the SPL (volume), and 3 dB is double or half the power.

[@BarefacedAudio]

Perceived loudness cannot be determined mathematically because it relates to how the human ear and brain work together to analyse sound. Could you expand on why you believe a 10dB difference to not represent an approximate doubling or halving of perceived loudness?

[@voxpathfinder15r]

6 dB is the drop off for every doubling of distance away from a loudspeaker. You’re confusing that with 10dB drop is perceived by human ears as half as loud. I E a hundred watt amplifier is only twice as loud as a ten watt amplifier so long as they are going through the same speaker cabinet with enough headroom before speaker compression
