SB Acoustics Satori Monitor

[Joachim Gerhard]

So when the Monitor is ready we need a sub ?

Here is my design for an easy to make cabinet that looks good and does the Job as well.
The baffle is staggered and allows delay compensation between the tweeter and the woofer. Diffraction is scattered so the cabinet has less influence on imaging clues. The second version has chamfered edges and should work even better. The edges can also be rounded.

Design number 1 can also be modified by putting felt around the staggered elements making the tweeter baffle flat in essence.

Hi Joachim,

Haven’t you considered using a ”ladder delay network” to electrically address the driver units relative acoustic center off-set instead of using a stepped or slanted baffle?

This would make the loudspeaker enclosure even easier to build, but at the expense of a bit more complicated cross-over design. Sonically it work very well and it’s very easy to fine tune once you have the basic ladder circuit in place.

I’ve found it to work very well when using shallow filters like a true LR2, but it’s over-kill/not necessary to use it with steeper filters.

Here's an example:

Sequence Two – Monitor
Sequence Two – Monitor BE

the sketches looks similarly to one of the Sonus Faber's bookshelf.

I prefer thick sides over a thick front
a thick baffle is like mounting the driver in a tube, which wouldnt be so good

Isn't actually that deep, for an average person, body resonance is around 70-120Hz.

What you call a "ladder delay network" has not only the effect of delaying the tweeter but it also adds an all pass term so you can not build a time coherent speaker with a ladder network. When i go the the Sequence Two measurements the drivers match in phase only over a quite narrow range. With acoustic delay by mechanical means i can do better WHEN i want to make an all pass crossover.
Henry, please show me the Sonus faber model that looks similar.
Tinitus, a thin baffle is not a very stable playground for the drivers.

here you go

[Joachim Gerhard]

Yes, that looks very similar. Is that an old Guarneri ? And yes, why not doing it the same way ? I think it looks good and is effective.
Here are some other ideas. Two of them are modular.
