I own a pair of Joseph Audio Perspective II’s and I think they are excellent, full range speakers. Prof nailed the description of their sound and character and I’m not sure I can add more to his insightful and accurate analysis.
My alternative speaker of choice has been the ProAc Response line, which in my opinion, excel in tone, texture and pure midrange. Very similar to the Perspectives, except in the low end, where I would give a slight nod to the Perspectives for weight, and the ProAc’s for bass articulation. The Perspectives have a gravitas that is beguiling. The sound of a drum set has the drive and authority that just sounds ‘right’. I’m a former drummer, with modest to diminishing talent, but that is my reference, having heard so many drum sets over the years. The Perspectives also get voices right. Piano trios sound awesome, come to think of it, I haven’t played any genre of music where they failed to excel.
My pair of Perspectives are being driven by a Luxman M700u stereo amplifier, with 120 watts of power. While the sensitivity is lower than the ProAc’s, I think the Perspectives must be an easy load to drive because I can get them to mid-80 decibels with only 1/4 to a 1/3 volume. Not a hard speaker to drive, IMHO.
