ive made about 5 boxes for myself and a couple for my friends. Obviously i didnt charge my friends anything, because they bought the materials and all. whats a fair price to charge someone a box? i know its all relative, but im getting ready to design and builda box for a 15" Fi Q 3-4 cu ft @ 32 hz. Is $100 shipped for a complete carpetted box too high? im not worried about too low because i really dont care about the money. its just a bonus i guess you could say. so what do you guys usually charge when you make a box?
