The front baffles on the N3 TL Towers, N2X, and N3S center that I finished in piano black all have square edges except the top baffle on the N3 TL has a 3/8" radius.. The edges on all the grill frames have a 3/8" 45 degree bevel using a router table.
The gentleman that I built the speakers for picked them up yesterday so I can't provide any additional closeups. I think the beveled edges turned out very nice.
