[QUOTE="Lakota, post: 4693283, member: 559574"] Out of the group I found the L7 to be the quietest. The highest score that I remember doing at the headrest was a 147.2 with a 15" L7. But, I've learned quite a bit about my truck since then, which is why I'm 3 dB louder now. If I did another L7 install it would probably be close to the R, but I have yet to see an install where a L7/CVX is louder than an R for a setup that peaks below 50 hz. I have compared a L7/CVX to a Type R in 3 different cars and the R was louder by at least .4 dB in every single one. The L7 may prevail over the R in a high tuned setup, but for most of us the R is just a better overall sub. Recently I did a sub and amp swap in my truck. The first setup (mine) is a zx2500.1 @ 1 ohm and Type R 15. The second setup is a HDC315 (aluminum coils) and a Powerbass 3000d @ 0.5 ohm. On the meter the HDC3 was only .3 dB louder than the R. Keep in mind that the HDC3 also received quite a bit more power. The big difference between the R and the HDC3 is that the HDC3 can handle high power for longer periods of time, which makes it a better sub for those that want to overpower their subs for a extended period of time. The R works much better in a lower powered setup because it is an extremely efficient sub. [/QUOTE]
