I ordered 4 x 4" bass trap bags for $30 each from ready acoustics for $30 each, bought my own JM IS300 (OC 703 equivalent) 9 2x4 sheets for $90. So I got 4 4" thick bass traps for $52 each. It costs around $90 including shipping when buying a pre-assembled bass trap So I saved aorund $120. Its worth it to DIY, even with the bass trap bags (which are super easy to use).
