No I am NOT the kind of person who thinks it's pointless to have a good sounding stereo system in your car, home, office, MP3, PC, wherever. I love listening to music and making one. I am a semi professional musician and a band master (Plays piano drums guitar bass flute and learning sax now) and a recording engineer. (My business card reads Senior Research Enginner at DaimlerChrysler)
I am also a DIY nutcase. I make my own amplifiers and speakers (for home). At one point, I was talking to Dolby labs, trying to get a one off licensing for a DIY dolby digital decoder. (they said NO WAY Jose)
The reason for "Can't justify spending that kind of money" is because I've got other things and hobbies that sucks my money. Period. If I use that Focal or ScanSpeak unit, I know I'll want to get the other things (like amp, processor, sound treatment, etc) up to the same level. Then it'll run me thousands. I simply don't have that kind of money for cars.
Besides, I believe that, with proper MEASUREMENT (something that lot of audio enthousiasts seriously lacks of doing) and SETUP, my $20 tweeter can sound pretty darn good. I know it'll never be as good as properly installed Focals, but I know I can make them sound better than Focals in a crappy setup.
Hey, The Money for my Home Theatre I put together in my basement, along with all the recording gears and measurement equipments, I could have bought a small Cessena 172 (I'm a Pilot too (VFR only tho ).
