Your crawl space is good for IB sub :awe:
I have thought of converting the garage crawlspace to one. I'd have to do the proper calculations and put in some "zig zag" brick walls in it for full effect. I recall hearing somewhere that concrete actually is an awesome sub woofer material, it's just that it's usually unfeasible to actually make. I think it would be epic. I don't think the neighborhood (nevermind the neighbors) would like it though. 😀
Though one of these days I may convert a single joist cavity into one, and have an opening in the living room (which is above the crawlspace). Could be a fun project in the future.
