Especially high frequencies are VERY directional, so it's a must to get them to point to the right direction. Aston Martins for example (whose audio system is made by Bang & Olufsen) have acoustical lenses for their tweeters - And usually aftermarket sound installs have tweeters in the pillars, pointing right at the driver! Unless placed behind a constant directivity horn (which can be 10"-12" wide), frequencies above 12k can have a dispersion of less than 10 degrees! Also, when having a multi-way system (like in an aftermarket car installation), it's important to make sure that the sound waves coming from the speakers at the crossover frequencies don't cause cancellations at the listening position... Anyway, there are lots of factors, that's what programs are for xD
congrats. Yeah its very important to get the position of the speakers correct, other wise the sound just sounds.. off.
When my cousin used to work at his old job (R&D labs for the ministry of defence) they had some software, that if you provided a model or lazy scan point cloud of the interior of the car and the relevant info about your car stereo and amp(s) you intend to use, it would spit out not only the best positions for the different speakers, but the exact dimensions and specifications of them, so you could build them and any speaker boxes yourself.
They tested it in the carpark at work once. they had one guy sitting in his own car which still had the default car sound system. then they parked a car with the new sound system next to him. apparently you couldnt hear anything of the default system, when turned up full blast, when they turned on the upgraded system they also apparently cracked a rear window
Finished with my speakers, and, man they're PHENOMENAL! First I redid the extensions on the cords. When I extended them I was about 11 years old, so I didn't exactly do a good job... They would cut out as you moved them about Then I aligned them to be perfectly on-axis with my listening position. They now form a perfect triangle, and since one had to be off my desk and on the piece of furniture that holds my printer (It's a bit higher), I added a soft pad underneath on the back side to make it point correctly height-wise.
Then the measurements... These were real trouble... The "measurement" mic I have is not exactly a "measurement" one... It had a huge dip at 1kHz to 3,5kHz (like 5 dB, which when equalized made a HUUUUGE HORN SOUND), with some other dips and peaks I figured out eventually - But thankfully it was almost in the bass range that was the most messed up (did have to boost it a bit to get some thump), and did pick up some resonances and distortion artifacts correctly..
So about an hour or so of modifying EQ filters later, I got it 85% perfect! They're more Hi-Fi-ish (and still have some peak at 2kHz+ making it sound like a horn which I still haven't figured out), so they're not flat, but they're MUCH better than they used to be. Stage imaging is clearer and just surrounds you, the high end is pretty crispy (Though I'd like it crispier ), and the bass is perfectly balanced!
I talking about people don't understand simple stuff! like "Kevin don't talk when i'm talking." "Chase go to your seat and start working!" There's a reason why they all won't graduate... My generation is the dumbest and the fattest.
What kind of stupid are we talking here? 5+5 = JELLO, "how do clouds stay up?" "kevin has butt cooties! stay away from him" Leaping off the roof of the science block while screaming " I had discovered anti gravity"
