Gordy made the waveguide covers today, my beast is nearly complete... allz I need now is to RTA it!!!
Staging is remarkably high, not sure how that happened, but I'm not going to complain. I'm having a hard time setting the gains, and really dont want to mess w/it anymore before building my $100 RTA.
How to make your RTA with $100 dlls. - DIYMA.com
All of the SQ cars I have been involved in, and owned, have been windows down rocking cruisers. This one sounds good at 75 with the tops off.
fair enough, why? I'll tell you why.... It's because you only have two ears. and those ears are about 6" apart, which is roughly the wavelength of a 500hz sound wave. Nothing above 500hz should ever come from behind your sound-stage, except for a car with a dvd-audio 5.1 system that was calibrated for the car, including the reflective surfaces... Which is next to impossible, which is why the concept is dead. My tl type-s had it, and it was only ok at best.
Go to a rock concert, and ask yourself where the rear "sound" is comming from there... It's the reflection. You can time-allign (delay) the source, but the reflection will always give away it's position... A problem that increases logarithmically with volume.
Now, also go back to the time when you or a buddy had a really kick-ass pair of reference loudspeakers, like some klipschorns, von schwikerts, ads, or some vintage kef's... And tell me how many speakers they had; my guess is two!
In large suv's, i'll put a separate set of components in the rear doors, and angle the tweeters up and towards the center of the roof for the back seat passengers, but in this car, rear sound seems to be a detractor.
Go listen to a world-class iasca/usac competitor, and look at the speaker diagram, unless they are running 5.1 dvd audio, you can probably bet they are setting their main sound-stage and image from a pair of components, or horns, and in some rare cases, a center channel...which is not needed in my car.
Your opinion of needing "sound" coming from the back is probably the result of a poor - or more likely non existence - sound-stage w/no proper image for left and right stereo separation.
If we had 4 ears, i'd be putting tweeters in the rear and running some signal processing. But we dont so my goal is to make it sound like eric johnson's marshal plexi is about 20 feet in front of the car, a little to the left with bass on the right of the stage, and the drums in the middle.
I got lucky and moved from high SPL systems to SQ systems after only a couple of years. It also helps that I didn't pound on those big systems all the time. The biggest sub I've had for the past 10+ years has been a single 12". I do have some high frequency loss (above ~17k), but I atribuite that to age. I don't pound on my systems now since I usally have my kids with me.:tongue:
