Rear ported cab placement?

  1. Any words of wisdom regarding rear ported cabinet placement?

    I'll be gigging a small(ish) 600sq foot bar room with my new Ampeg B100R combo tomorow night.

    I like to lean mine back against a wall so it angles up towards my head, and then stand 10-15' in front of it. The rear ports really shouldn't make any difference.
  3. One diameter or more between the port and the wall.

    If you are lucky and the stage has a corner to it, set it there so the two walls are making a V behind the port. About a foot away from the walls. That's the best situation I've come across. Now go ahead everybody, call me crazy.:bassist:
  5. Six inches to a foot away from the wall insures that you won't be blocking the ports, and the amp will have a little air circulation for cooling.

    I believe, the term 'diameter', is referring to "1 to 2 times the 'diameter' of the port/s", is equal to the minimum distance from a solid, flat surface... such as a wall??

    I do the same with my stereo speakers at home...

    On a side note;
    my 1x15", front mounted, no port cabinet puts out almost as much bass punch behind it, than from the speaker out front... makes for some thinking about cabinet placement.
