Please find the SPL graph after applying 1/3-octave smoothing

Very good setup. Have you configured LCR as full range or doing bass management with crossover ?

Something was wrong last time due to which high SPL was measured. I tried measuring again, this time I got proper readings at Volume 55. I installed SPLnFFT app in my iPhone and compared the reading in the phone with SPL reading in REW. REW was not allowing to calibrate, got a message that...

I don't have a SPL meter to calibrate the readings of REW. Is there any way to properly check/confirm the readings of REW any other way? As per the REW help, calibration is not required if USB Mic is used. I am selecting AVR Receiver in preferences->Output device and Master Volume under...

I switched off the subwoofer and took measurement to find out the SPL level from the front speakers. I took measurements at crossover of 100Hz and 150Hz in AV Receiver. I was hoping for a graph with increase in SPL level before the crossover point. But there are higher SPL levels at some...

Hi All, I have taken new measurements based on the inputs/suggestions. I have attached the new measurement file and below is the SPL graph After 1/6 Smoothing This looks to be better than previous scenario. Looks like null moved to 95Hz (previously there were two nulls below 100 Hz)...

Thank you very much for the responses. The subwoofer is not placed next to front speakers. I have attached the dimensions and positions of L/R and SW. Front speakers are around 1.5 feet from front wall. Since nulls are visible in both cases (crossover at 80 and 40), I believe these two...

Hi Wayne, Thank you very much for your reply. Can you suggest the options for removing the nulls? I am planning to try measuring at other possible seating positions. I am seeing those nulls even if I change crossover to 40Hz. Audessey selects crossover as 40Hz for all speakers after...

Hi All, I have taken measurement using REW 5.18 and result file and SPL graph is attache here. I have used Laptop HDMI port for sending Stereo audio to my Onkyo TX-SR 707 AV Receiver. Front Left and Right speakers are Polk RTI A5 and Subwoofer is SVS PB12 Plus. Audessey EQ in ON in AV...
