Help identifying this speaker?

That center speaker looks like an HTM2. I don't recognize the other speakers though. The almost look like they are 3-way tower speakers with some subs placed on top. Because look at the bevel on the main speaker portion, which is not there on the top square part. 

Agreed. This was from a post on another site and I was immediately rankled by how terrible the set-up is. 

Looks like a really nice DIY  professional job if they are.

Interesting that they 180'd the drivers from the majority of speakers.

That was my first thought, too. I don't know of any major speaker manufacturers that do that

Dynaudio went on a kick putting the woofers on top then mids and tweets, but that ain't Dynaudio. Looks like it was made exactly for the placement it's in.
