Because my living space where we watch movies is such a mess acoustically (with stairs, the couch has to be to the side, and we pull the tv out from wall at an angle above fireplace), it didn't make sense to keep my Wharfedale Opus setup. Also no place to put rear surrounds that need to hang on wall. I sold the center and rears, moved the towers to the office, and got a SuperCinema XL. Currently using an old subwoofer, but will upgrade to a matching one by GoldenEar soon.
I hadn't used the sub in years since the Opus 3 went down to 23 Hz. I need to finetune the crossover. Also trying to decide if it'll be worth it to eventually get some small SuperSat speakers on stands. Maybe I'll share a picture of the space.
