Reaching out as I am looking to have a enclosures built for a pair of book shelf speakers and possibly 2 sub enclosures. I am in the Chicago area but does not matter if it is local or not. If interested or if you can guide me in the right direction please email me. Thanks again everyone
Its worth it to scope out the yellow pages of sorts and find a small shop. I found one who was reasonable, and he's an audio guy. We ended up building him some speakers too, you never know who you are going to meet.
There are many car audio websites which build custom enclosures for subs. One site is caraudiofactory.com. They have their own box building facility in houston. They can build any thpe of box you want along with a single or double baffle and more.
