Are you liking your SB16s and do they still seem adequate in your space?

Hi all,

I'm new here. I've bought SB16 Ultra few week ago and pretty happy with it. However, I just realized it has humming noise, it sounds like the white noise from TV or radio. It makes me feel like there's a fan running inside the sub constantly. I've contacted SVS customer service and they were very helpful, after few emails, they decided to send me a new amp to try out. However the new amp does the same thing. I've tested the sub when it only plugged into outlet.

My question is: is there any level of humming sound acceptable for sub? or it's by design?

Thanks

Do you have any "Three Pronged" plugged in fans etc or over head fans, light dimmers etc running on the same circuit breaker as the amp?

Can you move the sub ( I know HEAVY) and plug it into the wall on a different circuit?

I ran into this problem with a "Ground Loop" hum with my Hafler Pro Amp for my R2R and TT. I went crazy unplugging devices etc and finally found a

a old power strip with a 3 prong plug fan for my AVR. I used a 3 into 2 plug adaptor and all is well again.

I've had them for about 7 or 8 months now and I've honestly had zero regrets or urges to upgrade to something else.

I don't really push them that much and even being in relatively big space, there is still a great deal of additional output I could tap into if I wanted to. For me and my room they more than meet what I'm looking for with both music and movies.

Any hum is not white noise. Big difference caused by different things.

Unplug your sub from everything. Just plug in the power cord. What do you hear?

My PB16 has a slight hum.. But I need to sit almost next to my sub to hear it so it has never bothered me.. I only noticed it because a few people did experience the same as you... but my PB13s are dead silent..
