I have an old Cambridge SoundWorks Desktop Theater 5.1 system which I'm currently using as a home theater while I patiently shop for a decent 7.1 component system...
Unfortunately the sub has started to pack up, it either doesn't work, or the bass sounds like a cracky speaker - bad description, I know. I'm not sure if this is just the wiring in the sub - its a passive sub, so I don't think there could be much wrong with the wiring - but I can't get it open.
Can I just use a cheap passive sub? Or how can I get this working again while I search for the 7.1 system?
Currently my TV, PS3, Music, etc run through this - so its kinda important to me.
