The sub could be shorted or the wire connections of the sub could be shorted, or there could be an internal problem with the amplifier such as a shorted output stage or failure of some other component(s)
You COULD run the Main speaker output to the large Red/Black speaker inputs, then some more wires Out from the other Red/Black connectors to your Main Speakers. That way your amp volume control will affect both equally.
Tweak the sub volume, crossover and phase to match it up to your mains.
You need to check the connections on the cross over board and also Ohm out the speaker to see if the voice coil is open. If you cannot get the same woofer, then you should replace them in pair, try http://www.parts-express.com//index.cfm?
I got the same problem, my sub was working perfectly and suddenly one day it did't turned on, so I think it is the protection from the internal transformer, it needs to be changed but I don't know the model, if someone else knows I would appreciate the info because it is a really good subwoofer for the size...
grady66, We will start with the easy one, Phase. The phase selector is a setting that can be adjusted by sound; which one sounds better? Either one will work fine. It's mainly for situations where the sub enclosure is located at a distance or behind the listening area. The 'in and out' crossover selector and the input from the receiver goes together. The 'in and out' crossover selector is asking if you want to use the internal crossover to block the bass from getting to the satellite speakers. Most home surround sound receivers only have the one sub out and most subs have both left and right inputs. When there is a single signal being fed to the sub you use the subs left input or buy a splitter and send the signal into both left and right, but either way will work equally the same.
There is two ways to connect the speakers to the receiver.
1) Cross-over 'In': you connect the output speaker wires from the receiver to the speaker inputs on the sub and the speaker outputs on the sub to the satellite speakers; the sub will get its sound from the input speaker wires.
2) Cross-over 'Out': you connect the sub to the receiver using the receiver's single sub out, then connect the satellite speakers directly to the receiver's speakers outputs; in this configuration the satellite speakers are given a full range of signal including the bass.
I have used #2 with the same system and had great results.
spurdoggg, It will be easy to pin point the problem. If your satellite speakers have been connect through the sub's in and output speaker connectors, disconnect them and connect them directly to the source of sound. If the speakers work its the crossover inside the sub enclosure. If the speakers do not work the speakers are blown.
Does it only pop and crack when its connected to your amp or receiver ? i have the same thing with my sub [its not cerwin vega] but when i turn my amp off the sub doesnt pop anymore so i think my amp is the problem not the sub , yours might be the same problem .
I bought my VE-28s and it did exactly that crackled, cerwin replaced part in amp but few months later problem persisted. they then replaced entire amp assembly and its been fine. i really push it to and its been fine. to test it, unplug the connection from amp/ reciever and see if it persists. if so its the sub, if not its the amp/ reciever. dont dump it, these subs really crank and can put out some deep loud bass.
