Just out of interest how much do those 'serious monitors' cost? I didn't realise Mayer were very well known in the recording side of things.. more for live sound.
The ATC SCM 300ASL listed in 2004 for 43,500 US Dollar, the SCM150ASL for 23,650 - 27,300 depending on finish.

Also what makes the compression/horn tweeters so much more accurate?
A compression driver / horn combo actually suited to monitor applications (most PA Horns and Drivers are not) will offer the foolowing:
1) Tight radiation pattern (directivity) control over the frequency range covered. If designed competently and specifically for the specific monitor the horn will in fact match the radiation pattern of the woofer at the crossover frequency.
2) Very high sensitivity (usually around 20db more than ATC's softdomes), which translates into much lower thermal compression and usually (this is again design dependent to a degree) significantly lower distortion for a given SPL.

To get a perspective on your views, what is your taste in speakers 3D?
I am currently listening to my own (check the website), however these I would not suggest for studio monitoring applications, they are strictly for "listening for pleasure" in normal living rooms.
When it comes to monitors all my favourites use coaxial or semi-coaxial arrangements of Drivers, that is the Schulze TH315 (older East German Studio Monitor) and the preceeding "System Eckmiller" derived studio monitors , the MEG RL-900 (which was also used in east german studios in the late 80's), the various Isofon Orchestra types, any of the larger format Tannoy's, the various UREI Monitors which used modified Altec Coaxials (the later JBL equipped ones are not as good) with their time-aligh crossover and of course Altec 604's with the Mastering Labs Crossover.
I also got on okay with very large TAD Horn System and the better JBL Pro Monitors, but my experience with almost anything that uses too non-conicident drivers has not been positive. Upon hearing the Meyer X-10 I was rather impressed (the low crossover point and 2-Way nature seem to mitigate the problem of non-coincident sound sources).

Personally I like active systems, soft domes and transmission lines, making something like the PMC BB5-A a dream speaker for me!
Active or passive is of little relevance to me per se, I will agree that really well implemented active systems (which take advantage of the ability to electronically time-align drivers and correct for other driver defficiencies (like even order dstortion) do have a significant edge, but just a bunch of Amp's and a textbook active crossover do not seem to work.
I helped a friend to move his big PMC's from the stock active system onto a digital x-over platfrom (a modified BSS unit) and we also modified the system further to improve the dispersion of the drive units and fitted a different tweeter (a Focal) and afterwards spend a lot of time using the features in the digital X-Over to time align drivers and to minimise the vertical lobing. The resultant monitor system was much superior to any other traditional multiway monitor I came across, especially when it came to "keeping the music together".
The cost for the whole setup however was quite astronomic (we used Valve Amplifiers for midrange and treble and Krells for the Woofers in the Bass extender and main speaker) and to me in key performance areas it still did not manage to match my then home speakers (Beauhorn Virtuoso with Visaton Subs and Supertweeters). Still, it convinced me (again) that time coherence is a crucial attribute in a good speaker and absence of it disqualifies entierly from being "accurate".
