^Focals are good, but you will sure as hell pay to get the good ones. The entry level ones are merely average imho.
If you want good speakers and don't want to mortgage your house to pay for them you need to look beyond the 'car audio' brands...
Personally i'm running these:
Usher 8945A 7" Woofers - literally one of the cleanest midbass speakers money can buy. Highly acclaimed amongst the DIY home audio community. Quite large and difficult to mount in a car. They just fit in my VY with some custom fibreglass mounts.
Fountek FR89EX 3" Midranges - there are midranges that play cleaner but they are large and awkward to mount in a car. These are small enough to fit on the dash/A-pillars. Cheap too.
Vifa NE19VTT-04 3/4" Tweeters (bottom right) - again, compact, reasonably priced and perform well. The founteks play reasonably high so you just need a tweeter to take care of the top octave, these will do it.
Total cost ~$450. The deal breaker for most people would be that you have to make your own crossover (quite difficult, need knowledge and measurement equipment), or use a digital sound processor (capable headunit or standalone processor). Personally i'm using a standalone processor and two 4-channel amps.
The other thing is that the installation is absolutely critical to make them sound any good. For me this means custom fibreglass door pods (they didn't fit in the stock VT-VZ plastic mounts) and custom fibreglass pillars to house the mids and tweeters. If you aren't any good at doing fibreglass, expect to pay a shop $500-1k to do this alone.
If you want a decent 'off the shelf' solution, i've heard good things about DLS 'Ultimate' 2-way and 3-way components. Reasonably priced too.
