I haven't done any research on them, but if they are priced similarly to the Pioneer shallows then I would stick with pioneers. Personally I would avoid hifonics speakers, their amps are good budget gear nowadays
The old Hifonics gear is quality classic car audio gear, but I don't think they did much for speakers. The company was purchased by Maxxsonics and blended in with their other brand names such as Crunch and MB Quart.
