Hey guys - I own the SVS PD10 which I love but today I heard a "boom pop", (thats how I can describe it) coming for it.

It scared the bejesus out of me and the volume wasn't set loud at all - like medium volume.

I was watching Eagles Live on HD DVD.

I never had this issue before with other subs.

SVS says it could be loose wires, power surge, etc.

I checked all wires and they are good.

Any ideas?

thanks in advance!

that is a common problem when a sub was overdriven...did it happen on a low? If you play the scene again, does it do it? Room size? Many people, even on top of the line subs, may overdrive there subs. They want that boom feeling.

Make sure your sub matches your other speakers and from there you can tweak it a few decibals higher. Many will adjust the sub with the mains with the spl meter in the worse area for a sub, resulting in a really hot sub, but not in the area where they took the measurement. They have to raise it a considerable amount to compensate for the low spl in that area, like the center of a room, but if you go to a corner, you may find that your sub is running ultra hot. Is your sub in the front and not in a corner...could be another cause of overdriving the sub to compensate for the lack of high spl feel?

Give us a little more info and we may be able to help. I went thru the same thing and now my sub sounds great. Mine was a result of over driving the sub.

The only thing that comes to mind is a static discharge or loose interconnect.

hi - thanks for the reply - actually I have the sub real low - 1/4 turn.

I have it behind the sofa in my 20 x 20 room. Plenty of room around the sub - no "hot" issue at all.

Onkyo 705 avr with Def Tech 1000 fronts, Def Tech Center 2000, and DT 800's.

I just did the Audyssey calibration and it set the sub at -3db with the volume knob on the sub 1/4 to 1/2 turn.

The only thing that comes to mind is a static discharge or loose interconnect.

loose interconnect? whats that?

Discharge? do you mean power surge?

thanks

If the sub is set at 1/4, your right, its not being overdriven...check connections again and then contact manufaturer again...

loose interconnect? whats that?

Discharge? do you mean power surge?

thanks

The interconnect is the RCA cable or XLR or whatever means you are using to connect from source to sub.

Depending on environment static, (like that from carpeting or draperies or whatever) can sometimes discharge (like the spark when you reach for the doorknob or shake someone's hand and get shocked). If the path it finds is through your interconnect or something it can make popping noises.

Ok thanks. The cable is ok.
The room is however fully carpeting. Perhaps some static electricity.
Or perhaps the Onkyo 705 is acting up.

Trying now to see if I can go thru the process of updating firmware thru Onkyo as some 705 users have also experienced this issue.

Thanks for your reply.

Hopefully it is something that simple. I hope you get it worked out.

Do you mean the PB10? If so that sub is hard to overdrive.
Is that sub on the same circuit as your the rest of your system? If not it may have lost power momentarily. Try unplugging your sub while it is playing and see if that is the sound you heard.

Sorry yes the PB10 - I actually have it plugged in by itself on its own surge protector.

Although the sub level itself is set low, what level signal are you feeding it? Is is possible you have the trim level of the LFE set too high? You could be overdriving its input stage.

how do I set the trim level? whats the input stage?

audyssey set it at 0db after calibration

Trim levels are the +/- db that your AVR set for each speaker. Audyssey set your's at 0, so it doesn't sound like you are overdriving it.

I would try a different plug and a new cord (both power and LFE). If you still have an issue, SVS should help you if you are still under warranty.

Can you repeat the boom? Has it happened multiple times?

Should I plug it by itself into the wall or another surge protector?

Its happened twice since I got the SVS sub. (less than a month)
Funny thing is I never got this "boom" from my older sub.

Some say it could be the "DTS BOMB" issue from Mster Audio DVD's.

In order to really fix this we need to find out if this is repeatable. Does this boom happen EVERY time you watch the Eagles in HDDVD? If so, than it cold be the source. If it happens at random times, then it could be your sub or your AVR.

If does happen randomly, try plugging it into a different outlet and changing your LFE/Sub cord.

If it still does this then we know it is the sub.

Are you in regular contact with SVS? Have they offered to replace some parts or send you a new sub?

we actually have near identical set ups and I have a SVS PB10 on order, so I really want to see if you have this fixed!

You have mentioned that the cable(s) are fine. Did you check both ends of the cable (one at the sub and the other at the receiver)? The cable should not spin freely on the connector. It should take a little force to move it. If it moves easily you need to either purchase a new cable or use a pair of pliers to gently squeeze the end of the cable a little tighter.

The cables are tight on both ends (LFE)
Happens randomly on Master DTS discs (only)

I do have the sub on the other side of the room opposite the TV behind the sofa.

SVS is great. Each email answered swiftly. They say it could be a DTS issue.

do you have your old sub? Try using that and see what happens.

Can you borrow a AVR? You could try using a different AVR to see if the pop still happens.

Start a spreadsheet you can start deducing what the cause is.

I dont have either!

I might have to get another receiver since this dts bomb issue has been hovering around these parts a bit.

then if that doesnt work I have to change out the sub from svs.
