    I've heard this repeated quite a bit. Taking a guess: an efficient cab needs less power to sound good? If i'm correct what are some efficient and non-efficient cabs. I don't even know if i'm spelling efficient correct.
  2. Ray, you were close. An efficient (yes you spelled it correctly) cabinet does not need less power to sound good, but to sound *LOUDER*

    The output or volume of a speaker or cabinet is measured in decibels. The louder a cab can go with the same amount of power, the more efficient it is said to be. They usually give the output of a speaker with 1 watt going into it at one meter's distance. Why? Just a reference point. For example:

    Cabinet A produces 95db @ 1 watt.
    Cabinet B produces 105db @ 1 watt.

    Cabinet B is said to be more efficient than cabinet A because it produces more decibels given the same amount of power.

    Which one sounds better? This is up to you. Speaker specs are really just a reference pont. To judge any speaker (bass cab or stereo) you really
    should hear it live. What sounds good to me may not to you.

    Hope this helped,
