Use this trick to massively improve your surround sound experience! (NOT A JOKE)

These are the 2 devices I use:
Laser range finder: https://www.amazon.nl/gp/product/B0863RK1KX/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1

SPL Meter:

Make sure you have an option to mount them on a trypod!
Let me know what you think and if you are going to try this! Should I invest in some equipment to record surround sound demo's? Let me know!
