Need small size speakers for fireplace.

I asked this some ~18 months ago, and now that the fireplace is finished and I am now in a position to consider an upgrade in the speakers I am using to augment my TV/movie viewing, I am back with this question:

What speakers are you aware of that would fit into a space 11.25" by 7” and retail at or under $1500 ?  I would likely buy a used pair. They will be used with a subwoofer, and can be closed box or ported.  I am looking to put together a list and will research suggested pairs online to narrow down pairs to purchase.  Thanks in advance.
