Question about Paradigm PS1000 Speaker

Sub thumps repeatedly

I have a paradigm Seismic 12 sub. The other day, I turned my system on the way I usually do. I had to switch my receiver input from TV to DVD and the sound was great for about 5 seconds when all of a sudden my sub kicked in(on auto) and all it would do is produce a loud repeated thump noise. None of the other speakers are affected. I powered down the sub, disconnected the RCA input, changed the RCA cord, moved the sub to a different outlet, etc. I even tried connecting the sub to another system and it still does the same thing regardless if the sub is switched to 'on' or 'auto'. It stops thumping when I switch the sub power off. Also, it only thumps once I turn up the gain, otherwise there is no sound coming from the sub. I am pretty sure its not my receiver. It must be the sub. Is my sub destroyed? thanks for the help mike

Re: sub thumps repeatedly

Since it still thumps i suspect the speaker is ok, but i suspect you have an electronic problem in the amp. since it is a powered sup & has the ability to auto turn on it has electronic circuits inside, take it to a service center for an estimate

How do I stop my Paradigm sub from humming and "burping?"

The amplifier that powers the sub is the source of your problems. Sounds like some power supply filter capacitors are failing.

My Paradigm PDR 12 subwoofer has started to make crackling noises. Is this an amplifier malfunction?

Depends when it makes these crackling noises.

If it's when the sub isn't being driven, then it could be the amp. (Check for bulging capacitors on the amp board). If it's when you move cables about then it could be a broken lead or a dry solder joint on one of the inputs.

If the crackling is when the sub is running then it might be the voice coil has distorted due to being overdriven with a poor and highly distorted signal.

Paradigm pdr80 no sound

If it is a powered sub, the sub power supply may have failed. There might be an open fuse.

JBL PB12 will have loud thump or pop!

First try to find the source of your problem. The easiest way would be to try your sub with a different audio source to see if the problem still occurs but is sounds more like there's a problem with the receiver.

I have a paradigm ps powers on fine when i plug in the rca cable into thoe back of the sub into the low level input it humms supper loud. i tested my cable and used another one same thing. could...

It sounds like it has bad ground on the RCA input assembly, you should Ohm out the ground of the RCA jacks to see if they are all connected.
How about the sender side (the amplifier) ground?

How long should a powered sub woofer last? It's on 24/7, but is not abused with long, loud playing. Mostly regular TV.I have a Paradigm PS1000, about 10-12 years old.

There's no way of telling really! Even if something did go wrong there's no reason to say it couldn't be fixed very cheaply. It could last another 10 years or it could go wrong in the next few hours.
I will say one thing after 12 years of service and never off you certainly have had your monies worth!

My Jensen spx 17 sub makes a loud thump on turn on.Is this normal or an easily solved problem? Will it damage the cone?

all the spx17 will do that, no it should not damage the driver.

We usually suggest to customers that it is best to leave the Sub in the Auto switch position as this will allow it to automatically switch on and off without the loud pop.
