I bet it is driving you crazy
Did you buy it local? Did you listen to those subs?
Buying to match other furniture without knowing more about the sub in this case, is not a good move, but you know that now
Subs are bulky, no getting around it, especially if you want good, deep sound.
Attick install is possible but not easy, if you have skills and space. It may shake your house through the frames. You would have to do an infinite baffle install.
If this is not an option, you need to find one that sounds best to you and maybe you can get a finis you need? Or, custom install veneer to match furnishings?
All depends how much you want it to happen.
