The sub 30 is awesome Really gets down there, unless your room is huge I doubt if you would need two. What are you using for your main speakers? I'm using the sonoran plateay interconnect on the sub it's working out well.I have settled on the sonoran plateau power cables on all components. They have burned in & sound better than some more expensive cords. The rest of my home th. system consists of all Revel speakers ,Salons , Voice Gems, Emprace, & Sub 30. I've since sold the Monster htps7000 & replaced it with a Running Springs Haley, This also made a huge improvement. I have Straight Wire Crescendo Speaker Wire & interconnects on almost everything else. I almost have the system complete except for mabey upgrading the transport, I have been waiting for Levinson to come out with a multichannel , multiformat player. I wish there could be some stability in the formats sacd , dvda, hdcd, ect, ect, ect. mabey someday these co .'s will get their act together & do whats best for the music industery before people stsrt loosing interest. Good luck on your choices
