Hi
@adamg64
Further to the advice of
@DavidT &
@kbfern
I've had a quick look through the pics you posted - which have proved helpful. These are my observations as to why you're underwhelmed by the sub atm. (Pleased to say it is fixable though!):
1. Physical connection of sub itself is fine
️
2. The subwoofer level - currently 0dB - is not right imo. or put another way...
At 0dB should definitely be noticeable! If it's not its not correctly calibrated (see point 3.)
3. Your front speakers are currently set to "large". This needs changing to "small". The setting is mot related to the physical size of the speaker, but how it handles its frequency range.
"Large" - means those speakers are playing the full frequency range try can handle.
"Small" - means you can set an frequency crossover for the speakers.
This is important in a system with a sub as it is purposely designed to handle those lower frequencies better than even the largest floorstanders. By setting to large you are starving the sub of those low frequencies.
Here's what I'd do:
In the SVS app:
1. Make sure you set the "Low Pass Filter" to off (will be greyed out if set correct)
2. Set the volume on the sub itself to about 50%
On your AVR:
1. Recalibrate using the Audessey mic
Post calibration change/check the following (on the AVR):
1. Change any speakers designated as large to small
2. After doing this set the crossover for the front & centre to 80Hz
3. Make sure the LPF/LFE is set to 120Hz
4. Post calibration your sub dB level in the AVR should read between -5dB & -8dB range. If you find bass is either too much or lacking, this can be adjusted a few dB up or down. But do it on the AVR not the sub.
As an aside (and completely option), I'd consider changing your volume scale on the AVR from 0-98 to the dB option.
Hope this helps. If unsure of anything just ask!
