Nirvana indeed! The Supercube does the job but I won't sit here and say it's totally killer. Better can be had and no doubt for less but I wanted to keep everything uniform for peace of mind. I did order the New Outlaw M8 sub a couple days ago, going to see how it compliments the room in empty corner. The Outlaw gear has always served me well so I have no doubt it will be pleasing. It's really affordable so if I don't feel it helps in the big room, I'll put it my smaller room that has a complete DefTech Pro800 system. That little prosub800 could use some help lol.
