The PB12 takes a little work but it did smooth out quite a bit after some frequency range tweaking and a couple of different placements and it still has more kick to it then the EP350v3, IMO. The PB12-NSD has a bump in the FR at that 50-60hz which needs to be tamed a little and stays flat from there. I wouldn't hesitate to recommend one as long as the person doesn't mind doing some tweaking. If you just want to plug and play then I would go EP350v3.
