    Clink on the links below to view threads on the most frequently asked questions and topics in the amps forum.

    If you have threads or links to contribute to this section, please feel free to PM an AMP mod for inclusion!

    Warning! Some of these topics are objective and to the point. Most are on much more subjective matters. The one thing you won't get in those threads is a single definitive answer. Like most subjective issues, you're going to get a lot of opinions, hopefully most of which are based upon real world experience. The point of having threads like this linked in the FAQ sticky is to give users a starting point. Just like in an individual and specific thread, these threads will contain a wide variety of answers and viewpoints. Hopefully after reading threads like these a user will be able to come back to the forum with a better understanding of the issue (even if the understanding they gain is that no one can agree on the subject ), and a more prepared assessment and explanation of their particular needs and situation.

    Save wood, prototype your cabinet design in Free Google Sketchup:
    Google SketchUp
    You can find speaker cabinet examples under File->3d Warehouse
    One you've drawn your cabinet, you can calculate the internal volume using one of the "Volume" calculators at:
    Home - Ruby Library Depot
    Hint: Temporarily plug the end of ports so they won't be considered in the calculated volume.
