Good to mention, narrow or slim column speakers have more problems with comb filtering than a Grimm LS1.On another issue. I think comb filtering is a time phenomenon too so why is that off topic ?

A picture
Good to mention, narrow column speakers have more problems with comb filtering than a Grimm LS1.
I use a program called The Edge to find out the best location of the drivers.There is clearly an off-center location of the beryllium tweeter on the ARA in the background there .... are you changing the geometry or just testing to see what works best?
I clearly prefer the very narrow speakers .... insane imaging .... but that is my personal preference

maybe you like them but have a look at the whitepaper from Grimm...I clearly prefer the very narrow speakers .... insane imaging .... but that is my personal preference
I heard some great "wide" speakers like stuff from Audio Note .... but the ultra-slim speakers are champs IMHO
Another example of a wide speaker in my program. It is not a best seller, far from it.
That was the one I mentioned, but obviously you didn't get it. Can happen.......Besides one of them are all small columns .....
I make rather wide speakers too. This is the Suesskind Puls wideband.
maybe you like them but have a look at the whitepaper from Grimm
"Psychoacoustics tells us that
below about 300Hz the ear will no longer clearly discern
direct sound, first reflections or reverberant sound. Presumably
the evolutionary background of this is that the
vocal range starts here. Anyhow, we can live with a
transition to omni below 300Hz. If we can get reasonable,
constant directivity above that, we have a design
spec!"

Design is promising, but driver suspension does not look like a quality hero:Another example of a wide speaker in my program. It is not a best seller, far from it.
Where is the peer review?maybe you like them but have a look at the whitepaper from Grimm

This driver costs 10x more then most.Design is promising, but driver suspension does not look like a quality hero:

In what frequency Range ?Good to mention, narrow or slim column speakers have more problems with comb filtering than a Grimm LS1.
Talking about peer reviews .....where are extensive measurements of your speakers in the manner of sound&recording and neumann or genelec do:Where is the peer review?
That does not mean, they are necessarily better.This driver costs 10x more then most.
Those small columns are omni up to 1kHz. You will have more problems with first reflections than with a speaker that has a narrower dispersion in the frequency range from 300Hz up . This omni behavior makes placement in the room difficult.In what frequency Range ?
I meant the damage(?) in the suspension between 8 and 9 o'clock...Design is promising, but driver suspension does not look like a quality hero:

I plan to send a pair of my speakers to Amir. Then you can compare to others that have being measured here before. On the other hand most of my customers are privat and non of them has ever demanded that I provide off axis measurements. I have the means to do that though.Talking about peer reviews .....where are extensive measurements of your speakers in the manner of sound&recording and neumann or genelec do:

Saying a flat on axis frequency response is easily to achieve, but then not showing the off axis behavior of ones own speakers. This is a little snobbish and not scientific.
Edit: 3 blue letters
This is a prototype and damage like that can happen when you move the speakers to shows and magazines. When I sell a pair like that I make certain that there is no damage. Customers do not accept damage anyway. Thanks for looking thoug.I meant the damage(?) in the suspension between 8 and 9 o'clock...
