I am deciding between a fibreglass box and a regular 3/4" MDF box but I have never seen a comparision of strengh, sound etc. What do you guys think for a daily driver?

 

fiberglass is stronger than mdf if u use 1/4 fiberglass it is compared to 3/4 mdf
It is much stronger and more dense than wood, plus u can shape it to whatever shape u want, will cost more money but can look nice, as for the sound it resonates better IMO

good luck

 

^ its definatly cheaper !
