SALS?A! - a very long story

Congratulations!!

But it doenn`t seem to end here.............
How large are the membranes unfolded?

Bernt

Thank you, Bernt.

No, it doesn't end here.
Instead of using the SLAM! motor when optimizing the membrane, I might build a mini SALS?A!; I have some magnets left.

The unfolded membrane is 301 wide and 273 mm high:

There are eight of them in each SALS?A!

The 74 film that I'm using is 360 mm wide.
 
massive project !! how low do you cross them ?

Currently I have for the mid an HP @ 300 Hz and LP @ 10 kHz.
For the tweeter I have an HP @ 3 kHz and some EQ at the upper end.
I might go lower with the tweeter.
HP and LP are 24 dB/octave.

I'm using Roon's procedural DSP as it is faster when iterating the filter settings.
When I am finished with the evaluation, I will make FIR filters instead with the filters setting that I have concluded.
 
looking good ! sounds good to. a bit to much of a demo song for me but (you know the ones you only hear in demo rooms/shows :) ). sounds great anyhow !

i bet people where rather impressed ?
Actually, it was a request from the public and it was the last song.
I didn't want to play it, but as everybody has heard it everyone can make the comparison.

Yes, they were impressed.
In fact, it was the best they ever have heard.
 
Hello
I would like to hear the loudspeaker. Must be a special experience.

You cut at 300 Hz. The way the speaker looks, I would expect very transparent voice reproduction. Too transparent. I mean to say, do an experiment with a wider baffle. For example a wooden slat 10 cm on one side and 20 cm on the other side. This would make the parts fuller, i.e. more meat on the bone.

Sensational work. congratulation
