Yes I have and it sounds great. This thing is a beast, the bass is so tite and low. It sounds soooo much better then my 4cf sealed box I built. Im still messing with the levels but so far I could not be happier. I have it wired for a 4ohm load and its only seeing 450watts but it is so much louder then the sealed that was seeing 1400watts. All I can say is all of you with a sealed RL-P that are getting low output and think its your receiver you should realy build a ported design. You wont be sorry.
