These speakers don't offer near the level of cost put into the tannoy drivers, but if they sound good, then they sound good. My coax pioneer car speakers are nothing spectacular, but doesn't mean the concept is bad. I'm curious why the coax design was chosen for these cheap speakers???

They sound great from almost any listening position it seems (one of them would make a perfect center channel IMHO). The crossover design is supposed to be simple given the way they are designed, which is a nice advantage.
side note: I had no idea there was a horn in my speakers when I got them for free: it took a while to figure out what was going on, because they sounded so good with only a single visible 12" driver - I was young and knew little at the time. I always liked them, then I found out from the internet that they actually are quite good.
