Think of it this way. $150 2-way, you get two drivers for your money. $150 3-way, you get 3 drivers for your money. Sounds like you get a better deal on the 3-way, yeah? NO! You get 3 shitty drivers for your money rather than 2 decent drivers. No comparison in my book. A good set of coax 2-ways that are made with component drivers with the tweet suspended in the middle of the woofer will sound hugely better than any 3/4-way setup made. 3- and 4-way speakers are always a case of more is just more, not better. Look at a 3-way coax. Are there any filters that divide the frequencies between drivers? No. Look at a good 3-way component set. There is a nice 3-way outboard crossover to divide the frequencies up so each driver is playing in its comfortable range.
