Much lower and you're talking bass trapping (corners and tri-corners). Also the side walls are reflected at angles not straight on so the angle of incident must be accounted for and you'll absorb even lower as the waves travel through more material. I use 1.5" with 2" in the back and with confirmation via REW of rt60s going thicker wasn't needed.

Of course I'd incorporate some combo panels like BAD or TAD or DIY versions at least on the side walls.
Thanks for the info. What are TAD and BAD

The short and sweet they absorb vocals and below and diffuse above it. This keeps the vocals detailed and accurate and keep the room sounding nice and airy and open. These are the swiss cheese looking panels you see in some of the newer installs. FWIW if you search on google you'll find some DIY versions.
