    the bass reflex enclosure

    The loudspeaker enclosure is an important part of your home musicsystem and should be given as much consideration as any otherpart of your system. In the last few years many different typesof enclosures have become available. Few of these represent

    anything new in the art of enclosure design. The majority are variousforms of the folded horn type enclosure and have achievedconsiderable popularity because of their excellent bass response.However, this good bass response is usually accomplished at theexpense of reproduction in the mid-range. Folded horns wereused in theatrical speaker systems for many years but wereobsoleted and discarded in favor of speaker systems using a

    combination of a straight horn and the bass reflex principle.

    ^ S \ ^ ' X \ \

    Altec Lansing has made detailed and exhaustive measurements inits acoustic laboratory on all types of enclosures, and thesemeasurements disclose that no type can equal a carefully designedenclosure using the bass reflex principle for smoothness infrequency response and over-all listening fidelity. The reason for thisis the freedom from phasing difficulties in the bass reflexenclosure as compared to other types.

    \ \ 1 I I IAll Altec Lansing loudspeaker enclosures are designed around thebass reflex principle and have been carefully engineered to take thefullest advantage of the potentials of your Altec Lansing loudspeaker.
