    Using main + sub and let the main roll off naturally without lower filter

    Hi all, I am having a question about using main + sub and let the main roll off naturally without lower filter. I agree that normally we would not want that as we want our main to be free from low bass freq to improve dynamism. However, I am wandering if our main is super good at dynamism (Ex...

    Harsh Sound

    Thank you for your suggestion. I tried swapping speakers from side to side and the system is still skewed to the right. Will try swapping speaker cables today. Have you measured the difference? I had REW measure for each speakers and the in-room Frequency response do look different. Does a...

    Harsh Sound

    Also can anyone suggest me the root cause and treatment for why my system is skewed to right speakers? I tried adjusting my listening position to be the exact center and speakers placement but whenever I closed my eyes, the Soundstage is a bit skewed to the right. Attached picture is my...

    Harsh Sound

    Hi guys quick question: I am having this sound card with me https://www.amazon.com/nengzhuzu-Professional-External-Recording-Interface/dp/B08KZG3N6P. I believe I can use REW to create calibration file for this soundcard. With the soundcard ready, can I use dayton emm6 mic instead of Umik-1...

    Harsh Sound

    @sigbergaudio @Keith_W thank you for your response, attached file is the measurement. I adjusted the mic to be exactly at my listening position (LP). The mic was pointed to the ceiling, not to the speakers. My LP is around 1.25m from back wall and 3.5m to the speakers. The distance between...

    Room acoustics - a full breakdown and analysis

    Hi folk, my system is: PC (Daphile OS installed) -> SMSL Dac -> Outlaw R2150 receiver -> Kef reference model 2 + SVS PB2000 pro. I measured my in-room response by REW using my Windows laptop. Then I used the EQ result in REW to apply to my Daphile 10-band EQ filter. Can anyone tell me how to...

    Subwoofer Comparison

    I set svs life on, crossover is done via bass management feature in Outlaw rr2150. The crossover freq is 80 Hz. Svs volume is -10db. I am wondering do I need to set phase =90 as my main is kef reference mode two.2 which has woofer floor firing instead of front firing...

    Subwoofer Comparison

    I am using Outlaw rr2150 reciever, not AVR. I guess harmonic distortion might be one factor. I am planning to do some REW measurement next week to EQ the SVS using its PEQ EQ feature. Tks for your reply.

    Klipsch r120sw provide more output than SVS PB-2000pro???

    Hi all, Hope that someone can help me with this question. I just upgrade my Subwoofer from Klipsch r-120sw to SVS PB-2000pro. I put the SVS into the same spot, in the front between my 2 main speakers. Strangely, I feel like the SVS is weaker. It cannot pressurize the room as strong as the...
