hi
I bought a pair of speakers for my studio Polk Audio Monitor Series 10 / original photo in my blog http://sgerasimuk.blogspot.com/2015/02/polk-audio-monitor-10.html
somebody tell me what exactly this model?
little information on the Internet - and all information is different
here are some examples:
1 - Sensitivity: 123dB ?? http://3.bp.blogspot.com/-Z-qQ5LS9ljw/VNTWG-KE6xI/AAAAAAAAahY/UTYwCYTIgsc/s1600/polk_brochure_back_pg.jpg
2 - Sensitivity: 89dB ?? http://www.hifiengine.com/manual_library/polk-audio/monitor-10b.shtml and http://web.archive.org/web/20110211053501/http://www.polkaudio.com/homeaudio/specs/recent/monitor10

why in the columns that I and columns that the link to the corporate site is different tweeters?

which parameters have a particular model that I bought?
thank you for your help!
