Hello gang,
I think I might have a problem with my new sub. But as it is also my first sub I am not sure it is a real problem, so wanted to ask here….
The sub is a SVS SB-1000 (non pro, but new, probably one of the last ones around).
The problem is that whenever it is on, I can hear a background noise. It is very noticeable, especially at night, so I am quite confident it is not normal.
Some facts:
- The noise is there even when no signal is given to the sub
- The volume has no effect on the noise
- Plugging one RCA or the two RCA has no effect
- I would say it is not a ground loop because unplugging all RCAs has no effect either.
- The only control that has some effect is the crossover setting. The higher frequency I set, the stronger the noise. With the crossover at, say, less than 80Hz, the noise is very much reduced.
So what do you guys think? Is the sub broken? Any ideas on what to try?
Additional question. My plan is to use a external dsp crossover. I understand (and this is what the manual says), that in this case I should set the sub low pass filter to the max (LFE position), but this is the setting that makes the noise louder…. Does it hurt to apply an external SDP crossover at say, 80 Hz and still keep the sub crossover at say, 100Hz to try to minimize the noise?
Thank you for your help, hoping not to have to send it back....
