Narrowed down to these 2 subs. Both seem to have very good reviews online. Anyone had experience of both/any of these? Room is 4x4.5 approx and will be probably end up being used with MK satellites so maybe 120hz crossover so would need a strong upper bass presence. 70% TV and movies, 30% music. I like subs to be fast and musical, not bothered about deep pressurized bass and ported subs. Wont be played anywhere near reference levels either with it being a living room, kids etc.
