A question about Impedence

    I was looking at an SWR that is 400 watts at 4 ohms. I wanted an 8 ohm originally because I heard that they are safer. Does the impedence really matter if you're not playing at full volume? This is a half stack deal, so am I safe just trusting the offer? Or am I better buying an 8 ohm system at a few hundred more?
     
  2. SWR heads run hot, but they're designed to and I haven't heard a lot of problems with them shutting down. There's nothing inherently unsafe about running an amp at 4ohms that was designed to run at 4ohms. I think you'd be fine.

    Probably the 4004, a decent amp, no problem there

    Where did you hear this? The 4004 or other amp will run at 8ohms just fine, you will get about 340 watts.

    The impedance only matters when you try to exceed the rating of your amp with the cab(s).

    Depends on who you are buying it from.

    Who told you that? That does not make sense.

    Do a search here on ohm and impedance, and read the amp FAQ, and this will start to make more sense to you. Good luck.
