Bass in your face!!!!!

Construction on the first of four 18" Super Scooper has been completed. I'm pretty sure the friend I am making these for will become hard of hearing. I'm really enjoying this design so I think I will scrap the sound I built for myself some years ago and build some of these instead.
One problem......... these are huge and I live in NY. Storage space is limited. Anyone care to house these if I build them?
