Fascinating, Alex. In addition to making an improvement in high power operation, it's likely to improve reliability/longevity if the driver is kept cooler. Looking forward to Pt 2. Would it be easier to place the intake slot for the cooling air in the bottom panel of the cab directly below the back of the magnet? That might save your having to make and mount something diagonal and simplify construction.
That was part of the inspiration - I think I talk about it in one of our videos. The BLX combos didn't sound very nice but they were very audible due to their dispersion!
With laminar flow, the problem is you tend to get the same air mass moving in and out. It's rebreathing the same air instead of getting colder fresh air and that hurts cooling.
Thank you so much for sharing! I love these nerdy videos reviewing the train of thought behind an innovative design. Perhaps you could also describe in another video the necessary education, knowledge, and skills behind your fascinating job.
I’ve been building 2 x 12 and 1x12 guitar cabs in my garage for about three years now and I’ve gotten pretty good and efficient with the tools that I’ve acquired. This weekend I set out to build a one by 12 that could fit under my bed, and I was going to use some of your design principles from the high-tech 1x12 you’ve demonstrated on the cha bel, with the flared sound-redirection port on the back. I ran into a few technical limits mostly due to a li It’s plywood supply and having to set up and tear down my shop every time I want to build something, but k just wanted to say thanks for the inspiration. It’s kind of a bummer that people don’t really care about cabs like you said, even though I’ve always really loved them . You could argue that nowadays the large guitar head is more unnecessary than a cab, because I like to run my power straight from my pedalboard and have only a cabinet with no head. My question to you is if I wanted to start selling my products here in the US what do you think is the first thing I should do to market them ?
Is there a way to make the cab powered like a mini fridge w thermostat that self adjusts based off of internal temperature? The fan sounds like the most simple path. Fun brain storming
Alex, BBII x two owner here. Very happy, however as tech changes, particularly the need for a huge sounding cab with loudness and dispersion (particularly in small stage/performance areas) and with the development of modelling, smaller efficient PA’s and IEM, I find I have a particular issue. I mostly use one cab; I do not want to lose the sound that the BF provides me, but I am really not needing huge volumes or projection, but do want the accuracy for monitoring. Often I find I am leaning the cab back to aim at my head, so wonder if this is something that BF would consider mulling over…..I want my FRFR capabilities, but want it more focused. At the moment, I’m considering tilt-back legs to be a relatively portable solution to this problem. When I need more power, it’s never a problem as I stack my two cabs. Thank you. I sold my 2x10” and 4x10” Bag End cabs and never once regretted it!
In your tests, have you placed temperature probes around the fins and the ports to measure the effects of your design? I think you are on to something. Hell, maybe even a small muffin fan would be even an idea?
Yes, we measured things because there would be no point adding a load of complication if it doesn't work! Adding a fan would be difficult in a passive cab because there isn't a constant voltage power source, so the port resonance was a way to get around this.
@@cletusrobinson why add a fan when the SuperCooler ports already do what we want them to do? And the last thing I need in my life is another thing to remember to recharge!
Any thoughts on guitar speakers cooling I.E. could they benefit from, or do they need added cooling fins and some sort of ventilation? And, do guitar speakers fail due to prolonged over heating or just spikes in power?
Companies like d&b use DSP processing in order to maximize the size/power ratio on their boxes, but obviously they have dedicated amps with presets in them. this would be a next step, but it involves active speaker processing in the amp
I love these video's. It's understandable but brain melting at the same time. Why not double up the side ports? Doing another port on the other side and maybe tweak the deflector a bit to get an "Y" or "8" air flow patrn?
Thanks Alex. Very interesting, and it created two questions/observations for your consideration... 1. Does the temperature of the air in the cabinet change the characteristics of the sound being generated? If so, I wonder whether changing the thermal handling of the cab might also change the tone of the cab in some way? 2. Does the hot air rising in the cab place additional heat stress on the tweeter situated above the main driver? I have a Super Midget on order. Are any your latest innovations in thermal handing incorporated in that smaller cab?
My only concern is the heat that you’re trying to divert to the side. If heat travels up, then why don’t you put the ports on the top instead of the side and move the horn to the side where the ports are now? Another idea is to use smaller speakers to cut down on the heat. Instead of 1-12” speaker, try 8-5” speakers?
The problem is getting shite in the cab with a top port. Also multiple 5" speakers can end up costing more if they are designed for bass duty (how many 5" do you know with 9mm xmax?).
The more of these videos I watch, the more impressed I become with Alex's expertise and passion for making better bass cabs!
Respect, Alex, for sharing your design and testing process so freely. The cabinet design community really are good people in that respect!
many thumbs up. thanks for making these videos.
Excellent experiments in the best Alex traditions, long live Barefaced and this approach!
Needless to say, You're a genius. This was quite fascinating!

That AVD slot reminds me a little of the old Trace Elliot BLX combos.
That was part of the inspiration - I think I talk about it in one of our videos. The BLX combos didn't sound very nice but they were very audible due to their dispersion!
@@BarefacedAudio I had one. I can agree with the sound not being great. The extension cab helped, being more traditional.
If I understand you correctly you basically built a chimney in a cabinet. I really like to see where this is going, looking forward to part two!
Love your reasoning, spot on.
I had never heard before that turbulence is good for cooling. How interesting. I would have thought exactly the opposite.
With laminar flow, the problem is you tend to get the same air mass moving in and out. It's rebreathing the same air instead of getting colder fresh air and that hurts cooling.

email us at barefacedbass@gmail.com and I'm sure we can guide you in the right direction!
I’ll take a Hacked up a prototype any day .
Continuous improvement 🤘🏽

@@BarefacedAudio Maybe a USB rechargeable fan? I'm seriously impressed on your continued pursuit of perfection!
@@cletusrobinson why add a fan when the SuperCooler ports already do what we want them to do? And the last thing I need in my life is another thing to remember to recharge!
@@BarefacedAudio Understood, sir!
I find myself imagining thermally coupling the cooling fins of the driver into large flat copper heatsinks on the outside surfaces of the cab..
I am very impressed with your approach!
I would love for barefaced to try and do studio monitors with that process :)

“If you want to make a lot of noise, be a blue whale, don’t be a bass player.” Duly noted. 😋 p.s. love your videos!
Yep. Good tip.
One of the greatest things I've ever heard.
Have you tried reversing the angles, instead of opening up larger going out like a horn, turn it around and make it getting smaller going out?
Companies like d&b use DSP processing in order to maximize the size/power ratio on their boxes, but obviously they have dedicated amps with presets in them. this would be a next step, but it involves active speaker processing in the amp

makes me cry seeing them all torn apart knowing how much those cost :(. In the name of science I suppose.
Problem? The air in the port will be staying where it is in the port just going back and forwards thereby having little ability to shift heat.
Sorry, I thought I’d explained this fairly well but clearly you’ve misunderstood - or did you not watch the whole R&D story?
Thanks Alex. Very interesting, and it created two questions/observations for your consideration...

Gonna call Linus Tech Tips and ask for a water cooled bass cabinet 😂
