Adagio Jr. or Adagio

My listening room is small...10x12. The neighbors are fussy about their red wine being disturbed by too much bass. I wonder about the rear port on the Jr's if they will send my neighbors running to keep the crystal from shattering? Any thoughts on which speaker would perform best at low volume levels? The speakers will be driven by CJ PV12AL, CJ Premier 11 amp, Music Hall dac, Music Hall MMF-5 and Kimber Kable all around.
think the jrs would be better in room that size,but then you would always be wondering about the sr adagios??
