That is the old AA. The new ones are based on the Dayton Audio BR-1 kit:

This is a more substantial speaker and gets you a significant improvement in the bass response over the old design.
If you are seriously considering the Pioneers, I would suggest you get the Sony Core Series 5" bookshelf speaker instead. It is currently on sale at half price ($108 for the pair) and is a much better speaker (but you don't need to believe me, just go to best buy and get both.- you have 14 days to return the one you don't like.
However, understand that the AA's provide exceptional bass for a 6.5" bookshelf speaker and will far outclass either of these smaller speakers (Sony or Pioneer).
For the wires, I've always put a floor mat or piece of carpet (non flammable) in front of the fireplace to catch any ashes, sparks, or debris to keep the floor in top shape and run wires under the mat.
