Perfectly accurate mid field monitor
“This is one of only a few speakers that I have tested with this good a step response”
“Of particular note though is the remarkable step response, which is presumably helped by PSI Audio’s “Compensated Phase Response (CPR) system”. This accurate time response is very rare in this type of speaker but here, PSI Audio has proven that it is possible.”
