SVS SB-3000 can‘t handle low input signal?

[Maccie]

Yeah, I tried to increase the subwoofer level in the AVR, +6dB in the speaker setting and an additional +6dB subwoofer trim, 12dB i total, still an issue at low volumes although better, but now I have closed to maxed out the speaker settings in the AVR...

Had to return the SVS 3000 Micro after trying pretty much everything at my disposal. Might be a less than great combination, the Micro and my Yamaha AVR that causes my problems with sub dropouts at low volumes.

If you get another sub, run the volume control on the sub all way up. Then see if you have the same problem. Let us know what you end up doing and how it works!

You mean an other SVS? It will not change, this noise gate is in all their designs.

Having owned both the SB1000 and the PB2000, I can confirm this is a frustrating issue. I could increase the subwoofer gain to run them hot, but doing so required raising the gain on the main speakers as well. This led to another problem: at lower volumes, the volume control steps became too large, with a single notch causing a significant change in SPL, making it difficult to fine-tune the volume to the desired level.

If I didn’t run the subs this hot, I’d encounter one of two issues:

1. They wouldn’t turn on unless I raised the volume above the detection threshold and then brought it back down again.
2. They would switch off entirely while music was still playing.

For a while, I kept the subs set to always stay on, but I wasn’t entirely comfortable with that setup. Eventually, I decided to do away with the subs altogether.

I got the Rel T5X instead, it works like a charm even at really low levels. A benefit of no DSP and only analog filters I guess. Honestly, that thing puts a smile on my face with music, so clean, I cannot locate the sub and it was real easy to integrate. Btw; Since I have mono blocks for my fronts, I use the LFE input on the Rel from my AVR.

There you go! I am glad you worked it out.
