He does know his stuff. Now I know I can't hear a .6db increase. I cant even hear a 2db difference.
What I was referring to, as when I accepted that the RLP's were defeated, is that I forgot that the RLP's only take 300wrms as where the Alpines take twice as much. The .6db difference was in reference to sending the same power to each sub, which its pretty safe to say, that the RLP's wont be able to take the same power as the Alpines. Hence my acceptance of a defeat in the Quarts. If there was a .6db difference in the RLP's with 600wrms each, then giving them half the power, is going to probably be roughly 3-5db difference. Thats an assumption, but I'm just going off what I have. The Alpines are the winner in the performance category, but price. Not so much. They may be the best SM sub, but their price is a bit outrageous. Not saying I wont possibly be picking up a pair to experiment with in my truck... I have always been curious of SM subs
