• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Re: The ULTIMATE SPL THREAD!!

Btw...there's a few units based on install needs.

KTX-100eq
PXA-H650

Not even close. In terms of anything, no one can know everything.

Theres a really popular auto EQ system in the home theatre world that Denon uses in their receivers. Pretty much the same concept here. Results are pretty much all over the place.

If you designed the listening area properly, you wouldn't need any of this stuff. Try one of those mats that are placed on the dash, that might help quite a bit if you've got speakers up there.

EQ can only be used to attempt to bring down peaks. Boosting nulls just ruins your speakers by forcing the amps to apply full power there just to attempt to achieve a flat sound. Usually doesnt help because cancellation is generally caused by physical parameters that are best solved by moving components.
 
Re: The ULTIMATE SPL THREAD!!

That's what most people don't understand; EQ is used to help promote a flat response in relationship to ALL frequencies. That means you should be making CUTS...not adding. Adding brings you that much closer to clipping once you've set gains properly. Turn the volume up and you have a much better chance at clipping the signal because of EQ boost. CUT RESPONSE USING THE EQ!!! Yes you can use it to boost but it should be kept to absolute zero if at all possible.

Matt is a big fan of GOOD INSTALLATION!!! However, there's inherent problems with a good installation in a vehicle. Unless you're sitting dead center of the vehicle you end up having to process something at some point. If you're vehicle isn't symmetrical...again, you have to change it's physical characteristics by either adding or subtracting real pieces to the interior...or you can process some more.

It all comes down to personal goals. Since I don't have the tools and equipment to be changing the interior of my vehicle I decided I would process.

THE BIGGEST DOWNSIDE to processing, especially when using an EQ, is that it's only good for one seat. Nobody enjoys but the occupied seat it was tuned for. Even then, if the person doesn't maintain the same physical characteristics of the tuner, it can be a different sound to everybody else.
 
Re: The ULTIMATE SPL THREAD!!

The only processing you should need in a car is delay for the left channel. Thats just about it IMO.

Perhaps a loudness curve as well. Cars have horrible environments so that'd be a useful thing to implement.

Setting up speakers in a car is still only good for one seat as well. A car is too small to have perfect sound for everyone unless you give everyone a set of headphones.
