  1. A midrange speaker is usually much smaller than a woofer, but with a surface area greater than the typical tweeter.

    2. Your answer:
    TrueFalse

  2. A sealed enclosure is specifically tuned to give maximum energy to a very limited range of frequencies, usually the lowest. In this arrangement, the woofers are fully enclosed in the box with the sound pressure being vented through one or more ports.

    3. Your answer:
    TrueFalse

  3. Highs are reproduced by tweeters mounted inside the woofer cones of multidriver 2 and 3 way car speakers and separately in other systems.

    4. Your answer:
    TrueFalse

  4. The common name for a complete amplifying stage in any audio amplifier is called a channel

    5. Your answer:
    TrueFalse

  5. The inside edge of the speaker dustcap is attached to the voice coil former.

    6. Your answer:
    TrueFalse

  6. Covering the voice coil assembly and attached to the speaker cone is the surround.

    7. Your answer:
    TrueFalse

    14. Your answer:
    TrueFalse

  14. The combined output is pulsed D.C. It is not A.C. because the voltage doesn't cross the reference line. This is an example of rectification

    15. Your answer:
    TrueFalse
