An egg carton is going to absorb little, only at limited HF bandwidth. (Acoustic materials are tested for absorption coefficients/"efficacy" at set frequencies). Because its well depths are uniform it will only diffuse at very narrow bandwidth. Because acoustic material convert particle velocity to heat, it will not absorb any bass. Particle velocity is zero at boundaries. You will need a quarter wavelength of depth to achieve particle veloctity to be absorbed. The cartons way shallow for this. Some bass traps invented convert pressure to velocity because bass wavelengths are so long.

Fiberglass is inexpensive and more efficient at absorption than egg crates and many other materials. I would buy pre-built diffusers. You will want to educate yourself about bass traps before using them.
