Hello All,
A month ago, I bought Wiim Amp ultra along with bookshelf speakers (polk R200) and an 8 inch sub (pioneer S-52W, it's an 8 inch down firing ported budget sub). It's setup in my small living room and is for music. This is the first amp+speaker+sub setup i have. So though iam close to 50, Iam a newbie. But i have read through a lot of information in this forum and has tried my best to get to my current speaker and sub placement. But I am not able to judge whether the sub placement can be made any better. I want to eliminate the nulls by moving my sub as moving speakers are difficult due to room constraints. After days of trial and error, here is my situation from roomfit. (Apologies if the screenshots are insufficient to provide any comments, can rerun roomfit and share more details in the weekend if needed)
Speakers are placed almost 6 ft(1.8m) apart and listening position is almost at similar distance (7ft) from the speakers . Speakers are in the corner close to the walls, 10 inches gap between the back wall and the port and 18 inches from the side walls. Sub is placed on the floor in front of the speaker stand of the right speaker as i felt it reduces the chance of they interfering with each other.
Roomfit in sweep mode gave the output as attached which shows dips at around 60Hz and between 150-180hz.
However roomfit in moving mic calibration mode gives better result - also attached (file name has MMC)
Physical controls on the sub are as below
Volume at 50%, crossover bypass is on and phase is 0.
On the wiim configuration for sub, crossover is set to 70Hz, phase is 0 and delay for main speaker is set to 8ms which was done by wiim auto sync and I tried to tweak it but 8ms delay and phase setting sounded correct. I have set input gain to -2.5 and used peq values above 400Hz based on spinorama values for the speaker. But I assume EQ is not applied during roomfit.
As for roomfit settings, I have disabled the boost mode (i.e enabled the setting), range is set 20hz to 400hz and smoothing at 1/6 and other settings are at default. I use the phones mic, so please ignore the spikes close to 8khz.
Iam happy with the sound but that may be because i feel i have spent enough time and feel i cannot do much better with speaker placement as it's a small room. But the roomfit showing the nulls in the sweep mode is bothering me and hence wondering if i should keep trying to find better placement for sub as for some tracks I think I hear the presence of the sub. Hence looking for guidance.
(Also want to say thank you to a lot of experts on this forum whose posts have helped me immensely to learn a lot that I didn't know a month before joining this forum)
Thank you.
