My next speaker project is going to be the GR  Research OB subwoofer:

Would it cause any problems to take the W frame and add storage shelving on the top or bottom in order to make it also functional furniture and blend into the room better?

Thanks,

No problems that I can see.

Aren't you going to want those away from the wall?

Aren't you going to want those away from the wall?

Yes, but where I have in mind for it I don't want it to look like a speaker just sitting there.

If you want to minimize vibrations, I wonder if you may want to consider the Linkwitz-style W baffle - in which the drivers move push-pull, in the arrangement shown there is still a force component that doesn't cancel.

Even so, I don't know how well that would work for your planned use - you may have to build them and try them. Perhaps consider decoupling the sub cabinet from the furniture around it? I think I saw someone do something like that here recently.

I cannot think of any reason that an OB sub could not be incorporated into a coffee table, so long as you don't mind a woofer basket hanging out of the middle of it!

I used to put an Ikea LACK table over the top of this, and it masked the ugliness some...

Thanks guys, we will see how it goes.

Not a problem, just a consideration:
A dipole woofer will excite vertical room modes least when standing on the floor. If you raise it up considerably, you may choose 1/5 or 1/3 of the room height to get the most homogeneous distribution of the vertical modes.
