No time to explain but here are the screen captures…..

SMAART I/O ended up displaying a 0.1dB offset to 94dB but was consistent over the full “gain range”. The Evo4 and the UA1010 stayed within level 1 specs AFAIK (i never read those spec but this is from “hear say”).

I did a little screen capture on how to go about this via Smaart. The data isn’t perfect but it never is…..

START OF PROCEEDINGS: NEVER SET UP YOU SPEAKERS LIKE THIS PLEASE!!!!!!

Did a screen capture after an advanced training last week. If the stuff in the screen cap doesn’t make sense start messing with them and try to figure out their use. That’s the way i found out……

If you do not know what this is all about attend a Smaart training. The screen capture was done after a remark on a post at the Smaart Users Facebook page.

Did another experiment on a gradient near a wall but this time with the Fulcrum Acoustic CS121 Passive cardioid 21″ sub.

Did the same experiment with a Front Back Front set-up as the Gradient set-up in the blog post before this 1.

Also i wanted to see if this array would still work when positioned in close proximity of a wall (1mt from the back of the array in this case).

During today’s advanced training the subject on Delay vs FIR on subs came up.

The result was sort of ok on both but i decided to record the result of Delay vs FIR

The same as the other posts on the Lake LM26 Apex Intelli-x2 and the Linea Research asc48. (https://timobeckmangeluid.wordpress.com/2020/12/17/processors-interim-report-lake-lm26-vs-apex-intelli-x2-vs-linea-research-asc48/ )

No x-over filters at this time (hopefully there will be when i find time to do the measurements). As far as i can remember the Bessel 1-8 order filters are set at the -3dB point (so roughly the same as the Apex if i remember correct) Butterworth an Linkwitz-Riley are the same as all previous platforms.

This is a follow up on the blog post prior to this 1.

This is a follow up on the post on cascading 2nd order all pass filters https://timobeckmangeluid.wordpress.com/2021/03/15/cascading-2nd-order-all-pass-filters/

The same thing can be done via FIR.
