[QUOTE="audioholic, post: 961063, member: 549629"] Ideally in a stereo situation, you would only use 2 speakers to reproduce the material. But we do not have the technology to produce a speaker that will give us the results we want between 20hz and 20khz. This is the reason for multiple drivers, the only reason. More point sources does add complexity as audiolife is talking about, but its a problem we have to live with. Even most high-end home speaker systems have multiple point sources, their advantagce being the ability to mount the drivers as close as physically possible, and the ability to align the voice coils laterally. In an automobile we usually do not have this luxury, but we do have some relatively crude tools to combat this (like time alignment, phase adjusting, etc). But, we also dont have a symmetrical listening environment in a car. Sound reflections are such a big issue in a car that I doubt all but the most trained ears would notice a point source issue in a properly set up 3-way system, especially in the midbass region. 3-ways really exel over 2-ways in terms of output (ignoring phasing issues mentioned above etc). At lower volume levels yes 2-ways can compete with 3-ways pretty well (some would even argue, better). But the higher you like cranking your volume knob, the more of a difference there will be between the two setups. The guy above who said he only would consider a 3-way with a horn setup confuses me. I have horns (not currently installed) and have studied them for quite a few years (including the readings of Jason Winslow among others) and I still dont understand that reasoning. One of the big advatages of horns is their ability to extend so much lower than a traditional tweeter, closing the gap between it and the subbass region.
