Meadowlark Audio, long defunct, is one brand that used first order xovers and time/phase aligned drivers. I have owned three different models and still enjoy my old trusty Kestrels.
Audio Physic offers time/phased aligned drivers now. As for first order crossovers, I believe I read that once but can't swear to it. I will say the Tempo offers about as holographic a sound as you'll hear.
