hello, i have 2 12 inch subs that require 2.5 cubic feet combined. my box is 4.5 cubic feet. a little large. how can i fix this problem without buying a new box? can i fill it? ive heard that makes small spaces bigger. what can i do? thanks
just cut the box down to whatever size you need. it's not all that hard. *edit* also, 2.5 ft³ is probably the bare minimum, not necessarily the space needed for the best sound. you might want to experiment and do some research to find the best sound.
loike auslander said modify the box or just build a new box $50 from a hardware store should get u the wood and if u have power tools and some glue and nails its not that hard to build 1.
