I have a PV-1 and am very pleased with my purchasing decision. I originally auditioned it partnered with a G95.
My requirement was for a sub with 'musicality' rather than deep-down, earth shaking 'grunt'. What I mean by this is that music is admirably, seamlessly and convincingly underpinned rather than the sub being the centre of attention - but that's not to say that the PV-1 doesn't go down really low (21Hz). For added effect, the PV-1 can be easily daisy chained.
For someone such as yourself, living in a flat, no vibration can be felt when touching the PV-1. The idea being that the sub will not communicate its presence via the floor to your neighbours. Moreover, for me, its aesthetic presence is something that can be showed-off in the living room rather than being something to be embarrassed about.
Although I'm currently utilising a stop-gap Yamaha solution at present (the G95 was a tipping point away from Meridian) until Meridian deliver something like a G71 (a G95 done right), I will continue to use my PV-1 alongside my Mission E81's in the longer term.
