Anything without a rear port really... $ for $ I haven't heard anything better than Sonus Faber Sonetto's yet - I have the VIIIs - the port is on the bottom of the tower.
Speakers good for close to wall placement
There are quite a few speakers I would like to purchase, but I need to be realistic. I will need to find some speakers that perform well when placed close to the rear wall. After that choice I can move on to selecting the proper integrated amp to drive them. Any suggestions on which speakers work well near the rear wall?
