I purchased this mighty sub as part of a trio. I do not have a need for it right now. Id luke to know that it will be appreciated in another system. Ive narrowed down my choice of sub to the Siesmuc 12s. They pack an effortless punch to your home theater or roll them off and give your other channels a rest trying to hit that low that the Paradigms do for a living when listening to 2 channel stereo. All of the compliance rings are pliable. The cabinet is in 7+ condituon. 8 isnt a stretch. A very faint buzz can B heard if there nothing else on line. My others Seismics did the same thing. When they are powered up, auto on, the buzz disappears. Full disclosure as I want to keep my audio karma strong. I do have 1 original box. I have a figure in mind thatd let it go... lets talk. I also have one seismic with a one self deatrucTED passive radiator. Paradigm, CANADA is not so forthcoming w/ parts. It is TBC. Anybody out there with a single PR for sale? Id prefer a local pickup. I just shipped an UltraCube 10. $120 and I boxed it at my expense. Pain in butt, but arrived unscathed. The Seismic 12 is considerably larger @ 67 lbs plus packaging.
