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.

Since this is a sub I assume the sound is not coming from the speaker but is mechanical and coming from the amp in back. The tranformer can be the problem if it has delaminated or may be loose. Try removing the amp and tightening the screws. If there are rubber grommets to isolate the tranformer don't overtighten. www.pardigm.com for contact info and parts. They are very nice. If the noise is coming from the speaker then you are still under warrantee and they will replace it free.

Yes it can be.You can check it with ohmmeter the impedance should be 4 or 8 ohms.But if you can disassembly the sub its better then you can see and check everything.My guess is that one of the cables on the speakers connector is broken and its just touching the conntact.

I have exactly the same situation with my PDR-10. Paradigm techs were of no help, don't me to take it to a service centre which i did. Of course when it was there they plugged it in and it stayed on for a day and a half so no problem right? Get it home, nothing, plugged and replugged, got it on once but not for long. Opened up back, everything including fuse looks solid and fine....to naked eye anyhow.

Hello there
this subwoofer has a built in crossover variable from 50hz to 150hz which means
that any signal you feed it the sub it will ignore anything but bass anyway. Hope this helps Kind Regards Ant
As for the
connection it is made quite difficult if you don't already have an amplifier
powering your other speakers, usually home cinema amplifiers have a low level
pre out for subwoofers, for which you would just need a phono to phono cable.
However if
it doesn't and you have any type of amplifier with at least 2 separate left and
right speakers you can connect the wires from these into the subwoofer and it
will output the bass from these 2 channels.
Another
option is to use a mono to stereo (2 to 1) phono cable where the 2 connectors
at one end connect to a tape or record output on your amplifier and the single
phono at the other connects to the subwoofer, the same would go if you have a
red & white phono (RCA) output on your TV you could also use this to power
the sub, in the worst case scenario you could use a single to single phono or
rca cable to connect one of the output channels (left or right) on your TV to
the subwoofer however this would mean that the subwoofer would only output bass
from either the left or right channel.
