I received the first of my two SB4000 subs yesterday. It is completely silent. My only complaint is that it weighs 102 lbs.
The SB3000 is a wonderful bargain for what it delivers. My only issue was that very slight noise.
I got my replacement amp and it made a very slight improvement. I really do enjoy the SB-3000s, so I will probably keep them and hope they do a revision to the board. I would go up to the SB-4000, but I do not have the room for them.
I decided to try replacing the amp on one of my two SB-3000. That way I can see what is going on. SVS is going to test an amp, to find one they consider low-noise. I really hope that it lessens the noise-floor, since I REALLY want to keep these subs. If this doesn't work, I may try the...
From what Ed Mullen told me, it is unlikely to happen with the SB-4000. If I went that route, I'd ask them to test it before shipping. He offered that with another pair of SB-3000 subs. It may be that my hearing is more sensitive in whatever frequency range the noise is at.
Ed Mullen from SVS contacted me today. He spent about 40 minutes going over all my options. He even extended my 45 day trial so I have more time to consider what to do I've never dealt with any HiFi company with such good customer service. He suggested I go with either the SB-2000 or SB-4000...
From everything I've read, the 1000, 2000 and 4000 series have no issues, just the 3000 series. They offered to send out a replacement pair, but to listen to them first. What if my hearing in that range is better? I do not want to be sending subs back and forth.
The sound I hear has nothing to do with the volume setting. I can literally hear it from 12 feet away.
I want to know how all the reviewers missed this? There are numerous highly positive professional reviews, including Stereophile, where not a word is mentioned of this issue.
SVS says that...
I tried unplugging the 'source' to the sub. Both subs are making the same volume of noise.
I got a response from SVC's tech department. As you can see, the SB-3000 is known for the sound 'issue'...
I just bought a pair of the SB-3000 subs. I was really enjoying them until this morning. I used the remote app to turn on the left sub first. I heard the power click and then a hissing noise. I then turned the right sub on and experienced the same hissing noise. I was sitting a good 12 feet...
