Hi, 2 questions : Is it normal that my new 4 HTS 3001 SE speakers sound a little weird compared to my older HTS 2001.2 speakers. I know you should be patient for the speakers to be played in fully. But I had no idea it would make such a difference. (My 2001.2 speakers were demo models, so I did not notice it back then) What would you guys recommend in terms of the reflex port (just above the binding posts). Should I put the plug in the port or not? All 4 speakers are hanging on the wall and 3 of the 4 speakers are hanging in a corner. Thanks for any advice!
