Hello All
I dove into REW and it is super informative. I recently moved a pair of DCM Time Frame 2000s into a small apartment and was determined to make the sound better. Without a real grasp of how phase changes occur I'm having a hard time understanding my graphs. A deep notch around 80 hz caught my eye. I moved the speaker outside on my 2nd story deck 3 feet from a sparse rail. Nothing behind mic or above speaker. Same deep notch and weird to me phasing. SPL was set at 80 for mic test. Proceed HPA-2 amp, Lexicon MC-8 in 2 channel analog bypass. Much more distortion than right speaker which I have yet to move outside. Even inside measured from my normal spot the right is plainly working better. I can hear nothing and would have never suspected any issues. Never go to the doctor when you feel ok
I could use help analyzing what is possibly going on. Not many 2000s around and I LOVE mine. The thought of taking out 24 screws on the back panel of a two transmission line speaker (terminate on front) is daunting and I am a skilled tech. Anyone who would like to look at some REW files or help me with this would be much appreciated.
Thanks!
