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

Here’s a little experiment i did on a Front Back cardioid Sub Array

I added a new tool to my inventory ;-).

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.

In this post I positioned a Gradient Sub Array with the same settings as in the blog post: https://timobeckmangeluid.wordpress.com/2021/04/15/gradient-delay-vs-fir/ near a wall and adjusted eq and level a little to get a “better” respons (better means the max reduction at the back wall mic’s and hopefully a better respons on the on-axis mic) . Normally with just 1 sub the reflection from the wall at the back will cause a (couple of) dip(s). More on this can be found in a blog post from 2 years ago https://timobeckmangeluid.wordpress.com/2019/08/12/subs-omni-or-nomnie-part-3/

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
