SDA in a car

[MacLeod]

I couldve sworn there was a thread about this already but I couldnt find it in a search so Ill just start a new one.

I know Im not the first person to think about this but is there a way to do SDA in a car for SQ competition?

I realize it would be nearly impossible for 2 seat listening, but what about single seat listening?

Im mean any car with a 15' wide soundstage would probably do pretty well at finals. ;)

Polk made an SDA crossover for car audio, I think Hoosier21 or Madmax might still have one stashed away.

Yep, we sold a few of them in the day. Not real popular unless you were really into the SDA home speakers at the time. At one of our competitions (actually a meet and greet sales promo) one of the reps from Polk showed up in a Caddy (remember this was 1986-1987) filled to the brim with the latest Polk products including a full blown car audio SDA set-up. I remember thinking how cool it sounded, but a bit impractical. I see them on e-bay once in a great while. Wild times back then being just 20-21 years old and around all that cool gear.

Thats kinda what I was thinkning about but I was thinking more of width as opposed to depth.

In SQ competitions, the stage has to be completley in front of you and as wide as possible, just as in a live performance. The thing I remember most about the SRT demo at Polkfest '05 was the stage was about 10' wider than the room!!! I wonder if that would be possible in a car.

Its always "possible", but extremely impractical. For someone like us, its too much of a hassle to try to predict every car out there with every location for speakers, or come up with equations to predict all of that. We could always tell you how it works so you could use it on your car, but we'd have to kill you right after telling you.

What if you have rear room sound perception (you think you hear it but have no drivers back there) like a live performance in a hall or a really good 2 channel system, are you disqualified?

You wont be disqualified but youll take a big hit in the points if its too much.

A little ambience is great if it gives a feel of a larger environment, just like in a performance hall - but if you get too much ambience to the point where you cant locate the image and/or it sounds like its coming from everywhere youll get docked pretty heavily.

Imaging counts for 40 of the 100 point scale in MECA so if you screw up the imaging, it hurts.

It would almost be worth it to have a stage 15 feet wide inside a car! :D
