Tomi is the name of a Japanese teenage girl horror movies series.. Where Tomi seems to die, yet never dies, and terrorizes the previous friends endlessly. It is fun in a Japanese sort of horror comedy way. Particularly the ways the friends slowly realize yes that girl they see who looks like Tomi.. well yeah she IS Tomi....

Thanks Liz ... I guess that’s out :duh:

Maybe Model T - TOM

I think the T-Omi is a great idea!!  Couple q's:

1. would you consider an option for class D, or other types of amplification housed internally within the speaker itself? otherwise, 10 channels of external amps eats of lot of budget and rack space..

2. does the ADC/DAC process affect the quality of the original DAC process that flows out of the preamp?  or would it maintain the same sonic qualities of the original D>A conversion?

3. any thoughts to using ribbon tweeters? :)

cool to learn there's yet another Bryston speaker project in the design phase! keep rocking!

Hi TJ

1. I think we would try to develop compacked external 5 channel amplifiers with maybe dedicated power to each set of drivers - like in the 21B.  Internal would be difficult as the weight might be an issue.

2. The DAC would be in the BAX-1

3. No .. ribbons are great for horizontal dispersion but lack any vertical dispersion.

How about Bryston Model TOD - for Model T (Omni ... Directional)

A speaker that will radiate in 360 degrees is a goods idea and there is already a niche for it. Amazon just launched Dolby Atmos music. The problem is that they support it with an "Echo" speaker that radiates in 360. I don't know if Bryston customers would want atmos music but maybe you could find customers that do want  atmos music service but would cringe at the idea of listening through an echo speaker:

Hi Brian

Yes I agree - once you hear a speaker that has the capability of real world dynamics it becomes quite obvious that dynamics with low distortion goes a long way to recreating real world sound quality.  I am going to test the A1 speaker as an OMNI first and if that plays out I will work on a Model T version.

I need a name for this new speaker - maybe Model TOMI  ... (e)?

Model T MD (multi-dimensional)

Model T MDA (multi dimensional array)
Or multi-dimensional active

I like the audacity of imagining something different. I agree with the idea that most drivers and box designs refine the state of the art to give us incremental rather than revolutionary improvement.  Yes some speakers sound better than others (and the Bryston actives are among the best I've heard) but I never heard a set-up that  made me to think I could not distinguish a reproduction from a real life sound. If a new way of skinning the cat can close that gap, I'm game to give them a listen. Go for it.

The guy i buy my speakers from (INO audio in Sweden)( it was he who made the Swedish test of the 14B SST) is working with a speaker with back firing sound.
Looks like this:




The back speaker is a 10" Woofer and a Tweeter.
The front Woofer is delayed the same amount as the distance between the front and back Woofer so they play in sync towards the listening position.
The back Woofer plays up to 300Hz and is non adjustable.
the tweeter comes in softly from 4000Hz and gets stronger all the way up to 20000Hz and is adjustable all the way down to off position.
All depending of the room and distance to the back wall.
The upward firing back speakers are very important.
He does not want any midrange in the back, he has worked on this project for decades and this is his solution.
I am not an expert but try to explain as good as i can from the thread in a Swedish forum.
Here is the complete thread for those who understand Swedish :D.

Interesting - thanks Raimo.

PS - What is is reason for eliminating the MIDS on the rear?

My guess is he is not trying to bring up the entire Sound Power curve, only even the bass in the room and get rid of the drop-off at very high frequencies in the Sound Power.  A number of companies have tried this with tweeters on the rear.

It is a different design goal from what we are doing.

As i understand it he thinks that reflections in the mids are destructive. I dont know about the things you mentioned, you may be right.

Good morning,

This is why I love Bryston. Very interesting concept for you to conceive. Will this primarily be a DSP module encasement using existing speaker models or will it also include a new model speaker, such as mbl? Also, before you retire, they do have cloning capabilities so have them look into it before you decide to leave...in 2050 😊

Thanks and look forward to your reply.

Hi Robert

A version of the Model T I think with rear drivers and using a BAX1 to control the drivers through a GUI.

How about an open baffle/dipole system? If you want sound to fill the room open baffle is a great way to go.
Daudio is doing really interesting things with open systems, usually ending at the top 3 for sound quality at european audio shows.

The sharp edge right underneath the tweeter *will* be audible. That part of the baffle should be flush to the mid.
They do look good though...

You could look at the old Design Acoustics D-12 speakers from the early 70's.  They were dodecahedron with downfiring woofer, top firing midrange, and 9 tweeters and a port on the other surfaces.  I had a pair for 35 years and they were very convincing of large orchestral music.

Hi

The issue with a dipole is there is no polar energy at the sides of the speakers due to the cancellation of the dipole design.

Thats why we decided on a Bipole as we can distribute the energy equally around the whole speaker 360 degrees. With a dipole you also have low bass cancellation due to the out of phase info from the rear wave cancelling the front in-phase wave.

Hi

Yes i remember them.

The unique advantage we have today though is to use DSP to control the overall 'Sound Power' into the room whereas back then the radiate power was the same in all directions.

Not in this case :wink:.
These speakers are strictly engineering designed for function.
The first 2way version was made in -78 for a hearing study and was only intended as a monitor with as little manipulation of the audio signal as possible.
He was forced to start to fabricate them due to high demand from people who heard them.
He has refined the original design since then :D.
I have a other version of these speakers and it is the best speakers i have ever heard.
He only makes them on order.
There is a commercial version, Guru QM60.
