Simple test to check speaker and its direct frequency spectrum via amp return with my cinema THX crossover monitor.
I matched the levels so they appear the same the mic distance I can alter it, move it closer inwards or move it further back place another mic near to bass reflex port along with mic directly on axis with JBL 4647, centre channel LF JBL 2226.
I can see the amp return direct showing the LF range I can alter the Behringer DCX2496 crossover and watch the freq spectrum changing.
I had a lead patched into the computer with few alligator-clips to the 3.5mm jack. One output to input was the microphone the other output to input was the THX monitor amplifier return, good as if I connected that directly to the amp it blow the computer up.
I opened two windows of TrueRTA as I was using an audio mixer preamp for the Behringer ECM8000. One window TruaRTA for left channel Amp return and second window for TrueRTA right channel microphone.
I can measure the speaker vs its power input.
