I just got a brand new dd 3510 with the supercharged option and I put it in a downfiring ported box tuned to about 33-34 hz with about 1.8 cubic feet before displacement that I built. I am powering it with an MB Quart Discus 1000.1 wired at what should be 1 ohm. I don't know if it will sound better after it is broken in or what I'm just kind of worried about this expensive sub not sounding good. I know I read it is supposed to be tuned higher and I may build a new box if the sound doesn't start to improve. If it isn't getting enough power can someone let me know I plan on getting a crescendo bc2000d soon. I am new here and any help would be appreciated. Thanks.
