Forgive me if it is a wrong section. I need help with my subwoofer and its frequency response as it is too high in some frequency.
First thing first, my setup.
Amplifier: Sony STRDN-1080
Front Speakers: Aiwa 3-Way Floor Standers (Not sure about the model as these are Vintage and very old and Very Big, but sound good.). I also have Q Acoustics 3020 for fronts but decided to use these old Aiwa due to their size, sound and as they are floor standers, I don't need to use stands. I am using the Q Acoustics 3020 with Sansui amp for stereo listening.
Center: Q Acoustics 3090c
Surrounds: Polk T15s
Front height: Sony SSCSE Atmos enabled top firing speakers
Subwoofer: SVS SB-2000 (seated on top of Auralex subdude ii)
Room: Room with a single standard door entry. Size: W 3.8m x L 4.0m x H 2.7m, carpeted floor with plasterboards on walls.
Due to size of the room I am limited in the placement of subwoofer.
Overall sound is great, I like how this setup sounds. However, I find the Subwoofer can be bit overwhelming in some instance.
For test I am using Dolby Amaze Demo with Dolby Atmos 7.2 True HD Lossless audio (From digital theatre demo downloads).
During this demo the Thundercloud strike (0.38 minute to 0.40 minute into clip) goes boom and very much overwhelms the room with boomy bass and I find everything rattles. To narrow down the frequency, I ran bass frequency youtube video, and in that I found the Subwoofer becomes very high at 40hz and 45hz, as it seems to be at its peak, subwoofer does goes low to 15hz. rest of the frequency is fine along with the all of Dolby Amaze demo except that Thundercloud strike. As I increase the volume, this becomes rather too much for enjoyable movie experience. I am not sure what can I do.
Initially, this was an empty room without any chairs sofa or any furniture of kind. So I had started with some Acoustics pin-boards in colours and stuck them on wall, which has improved the brightness in audio (High frequency), Also have some Acoustics absorber foam behind the fronts and centre speaker, and added two bass trap in back two lower corners. I now have a leather couch in the back wall, toy storing cabinet and toy tent in the room along with lots of toys (Between starting to build this and now, I have had a baby and room became more of a toy room than media room
). So, placement of the Subwoofer has became limited and is on front in between Centre and front speaker
Lowering the subwoofer level lowers overall bass and feels like there is no subwoofer, when I have it as is after the calibration it can be muddy in some instances. I seem to have bass standing waves in the room. Unfortunately, I do not have the luxury of testing another subwoofer in this room.
I am not sure what to do here. Any advise or suggestions please?
