Ultra flat cabs

[Redbrangus]

Electrostatic hi-fi speakers are fairly flat.

And unfortunately, can't make anything like the SPL needed, especially not with bass frequencies. But gosh, they sure sound nice in appropriate applications.

I'd be interested in knowing what the theory of operation is for these speakers. Electrostats was my first thought, but I know that can't be right... so what's the fudge? Mark me down as skeptical.

I also think the 30lb. weight advantage might be somewhat negated by the 30lb. stand you'll have to have to keep the thing from falling over on stage.

They do sound good. I’ve seen them used in a hybrid way with bass speaker cabs.

 

[ghiggin1079]

If it works, it works. I wouldn't mess with it.

 

[Lo-E]

Electrostatic speakers do sound very nice, albeit weak in bass. They also work best a couple of feet away from the wall, which could negate any space savings on stage. But this product, theoretically, is not an electrostatic design so it’s probably immaterial.

The weight appeals to me, of course, but I’m not sure that the form factor is an advantage. Color me cautiously optimistic.

I have to say that the statement “We figured out the physics.” Doesn’t fill me with confidence. Figured out the physics, did you? Well, I would bloody hope so if you’re designing a bass cabinet! Isn’t that the whole point?

 

[Redbrangus]

IME, when someone claims to have 'figured out the physics', they are asserting they've developed a technology that is not confined by the boundaries of conventionally understood acoustic principles. Seems like that usually proves to be false. One of nature's immutable laws: there's no such thing as a free lunch.

 

[/\/\3phist0]

Why not? The weight saving is a good point, but I agree that the principle still needs further optimisation.

How many here boast of a 30 Lb cab , while stating how much they’d love an 810 but just can’t move it?

Look at the article I posted about the model 20. Some of the questions posed are addressed.

Eminent Technology Model Twenty Guitar Speaker

It has a kickstand !

Introduction​

The electric guitar music industry has used the same technology, a direct radiator loudspeaker for 70 years. It is time for something innovative, the first flat panel guitar speaker cabinet is also the first green technology loudspeaker.


Tone is most important, clean tones need to be clear and detailed and lead tones need to powerfully convey the setup of your instrument, amp, and pedals.

NAMM 2023​

The Model Twenty received a NAMM 2023 Best in Show Award! A web page about our exhibit is coming soon.

Tomo Fujita comments on the Model Twenty!​

"Here is a clip with a flat speaker cabinet Eminent Technology model twenty (through my Fender Bassman head) It sounds so clear that it made me want to practice! This reminds me amazing water at Hida Takayama Japan! (The most amazing taste water ever I drink!) Please watch this video. I thought I stopped the video but actually it went another 23 minutes of playing!"

About The Model Twenty​

​

The revolutionary Model Twenty has the diaphragm "cone" area of a 4 x 12 cabinet, but is much more convenient and weighs half as much as a 1 x 12 cabinet. It disperses sound around the audience better than a traditional guitar cab, if you play Electric Guitar, Acoustic Guitar, Keyboards, Sax, or Synthesizers in a band other members will hear you clearly and listeners will not need to be directly in front of your band to get impressive sound, your tone will be the same for everyone in the audience.

Back of the cabinet​

The model 20 is an open back design that plays an octave lower and an octave higher than a traditional guitar speaker cab. Switch selectable settings optimize the performance, clean for acoustic guitar or other instruments and two lead settings for electric guitar tone.

A retractable kick stand​

A built in kick stand pivots and retracts into the back of the speaker which allows easy transport



This patented revolutionary design is half the weight of a conventional guitar cab, about as thick as a typical electric guitar case, is easy to transport and has a better presence on stage while taking up much less space. It can be used free standing, or against a wall.

View of Inputs and Tone Switches​

Electrical inputs are the upper right hand corner and tuning switches are on the upper left hand corner. Tuning switches are for bass cut, clean and lead sounds. For lead guitar you might want to use the bass cut and either of the treble cut settings. For other instruments like, keyboards, synthesizers, saxophones, violins, or wind instruments, you might want the full range capability of the Model Twenty.

The First Green Tech Loudspeaker​

While the diaphragm area of the Model Twenty is similar to a 4 x 12 cab, The materials and wood products used in fabrication are much less than even a 1 x 10 cab significantly reducing materials consumed during production.


Since transport fuel to move equipment consume much more energy than the electricity a band uses at a gig, by removing the need for a trailer or a van, adoption of this technology will significantly reduce the carbon footprint in the performance side of music industry.


As we develop fun new products around this technology, a stage monitor (link below), bass guitar, and PA system, are planned,your bands stage presence will look impressive with a substantial weight and transport cost savings.

What Customers Say​

"I just wanted to let you know that my Model Twenty arrived safe and sound and is playing like a dream."
"I am very pleased and have already begun to spread the word around. Hopefully this will drive more business your way and get the musician community to start using these innovative speakers."
"Thanks for being a solid communicator and trustworthy purveyor throughout this process. I took a chance on this and it paid off."

I also think the 30lb. weight advantage might be somewhat negated by the 30lb. stand you'll have to have to keep the thing from falling over on stage.

Even if you add a 30 lb. stand it would atill be half the weight of an 810, no?

 

[Iristone]

How many here boast of a 30 Lb cab , while stating how much they’d love an 810 but just can’t move it?

I think the SVT-210AV and SVT-212AV have got their followings for a reason, no? They sound reasonably close to an SVT-810AV, but are lighter and more portable.

 

[SirMjac28]

There's probably ten people at that venue in the picture and they don't look like a hard rock band so a $2600 cab would work out fine.

Specifications: Weight 21 pounds, Height 32 inches, Width 22 inches, sensitivity 99dB - 2.83V at 1 Meter, recommended power 20 -100 watts, impedance 8 ohms, Price $2600.00 each, price includes shipping.

I interpret this sensitivity data as meaning the maximum SPL is somewhere around 120dB (100 watts max power). At some undefined guitar frequency. That might work for some folks. My casual observation is that this miraculous 'magnetic planar technology' suffers from the same physical limitations as electrostatic diaphragms: it doesn't provide enough excursion to move enough air -- countering that limitation with additional surface area can only be taken so far.

 

[Dincrest]

Lightweight is good, but the cabinets' dimensions still make them challenging to transport unless you have an SUV or something. Plus, yeah, they look too fragile to survive the rowdy punk shows I played in the 2010s. And there's no tech specs to indicate how loud they can even get.

I'll stick with my two 1x12 Bergantinos and Peavey MiniMax head. Portable, modular, durable, and LOUD! My rig could easily fit in an inexpensive subcompact, be carried up a flight of stairs to an upstairs venue...

This is what we're really waiting for.
Brane Audio

Loud, low, and small without having to use a massive amp.

 

[Jim Nazium]

I'm skeptical. AFAIK, one of the problems with open-back cabinets for low frequencies is there's a wave coming from the back that is 180 degrees out of phase with the one coming from the front, and they cancel out. How do they get around that? If they can really get the sound pressure level and frequency response of a sealed 8x10 in something that small and light, then that's awesome, although it sound like it might be very expensive.

 

[logdrum]

So I have been shopping for a studio monitor recording upgrade and found about Barefoot speakers. He has a technology called MEME - Multi Emphasis Monitor Emulation. Powered monitor with DSP that retunes the monitor to sound like the obliquitous Yamaha NS-10, Auratone cube, Hi-Fi speakers and truly flat. I do not think there are truly flat bass instrument speakers. By the way the cheapest Barefoot are 1900 a pair. Ouch

(I own a pair of 1.7i`s). Transparent. Moderate to good Bass.

Also, they work best AWAY from a wall (back side).

Those are the specs for the model 20, not the bass cab
