I believe you are referring to the Philharmonic Audio (Dayton based) Affordable Accuracy?
If so I A-B'ed these two speakers and preferred the AA's to the 340's. Not by a lot, but given that the AA's cost a good bit less, that made them a real bargain.
Here is my post from around the same time I compared them:
I'm looking at the 340 SE's vs the JBL 230 and Elac Debut 6 and B&W 685 S2

I would also consider the JBL Studio 530 if
@Soundman can wait for them to go back on sale for $350!
Last, while the 340 offers greater efficiency, ability to play louder, and deeper bass, The 170 actually has a better frequency response per Ascend's measurements. If you plan to use a subwoofer (or two) and do not need to crank the piss out of them, you might consider the 170's.
The 340's dip at 2500Hz looks to be the most notable issue since it is in the range where our hearing is most sensitive:
