There is no problem with the driver; that's a superb driver. I'm sure it will give you good SPL with levels of THD that are well below audibility. But the problem is the frequency response curve. I don't care what quality of driver you use, if the FR curve is not to one's preferred shape, it's not gong to sound like the best quality. The FR curve is a massive factor in perceived sound quality - even if everything thing else is theoretically perfect - the FR curve will be the final determining factor. I would recommend using a DCX2496 with the Envision Electronics 12V PS module. This will let you shape the LF response to ANYTHING you desire; letting you get any degree of 'tightness' or 'extension' that fits your preference. In addition, of course, you get to have a great active crossover to control your system.Yeah. Kinda hard to read anything about rolloff there, with the gain being as it is. Big jump at 70ish Hz and then looks like a 6dB/oct increase as you go down. But there definetly looks like a 'base gain' of about 20dB! Wow! So I think output shoudn't be much of an issue. I' more concerned that I'll have no means of EQ in the car. That's out of my price range, I think.
I'll look into this some more.
Anyone have experience with the RL-p12 in car for sound quality? Any other drivers that would do a better job on a budget?
