Oh, you may have mentioned earlier about it being a first production piece. (and I missed it)
It's fairly common to have a few components that can't go through Wave solder or a HASL process, and have to be hand soldered. (Especially in low production runs, as I suspect these will be)
It just seemed a little out of place; at that price I don't expect to see the same cross-over methods used in a $500 pair of speakers.
I don't mean it as a put down, I'll bet they sound great... Just a little taken aback is all.
