Ask a Question
  • How many speakers can you do per Transformer

    Normally you need one for one speakers for 70v, because you need adjust the volume separately. If you have dual voice coil, even you need two pieces transformer for one speaker


  • I think I have 2 TFS6 Rock Speakers. Inside one of them, yes, i opened it, the transformer switch is rusted. Can I re-solder the speaker wires with outdoor speaker wire and install this SP-70V-TA in line on the outside of the rock?

    TFS6, we don't have bulit in transformer, just use external transformer SP-70VTA.
