3-Way Driver Design -
The KLH Model Five is a 3-way design featuring a dedicated midrange driver housed in its own internal enclosure. It's the midrange driver's responsibility to handle the most significant, middle part, of the audio spectrum. This portion of the audio band contains the vocal and musical instrument fundamentals which are most familiar to the human ear; and where accuracy, or inaccuracies, are most easily detected. In a three-way design, having a dedicated midrange means the driver can be optimized for this specific use, since it doesn't have the additional burden of reproducing lower & higher frequencies in the audio band. This results in truly remarkable clarity of vocals & instruments with less distortion.
Acoustic Suspension MDF Enclosure -
The KLH Model Five incorporates an acoustic suspension (sealed) enclosure for accurate and linear sound reproduction. The enclosure is made from structurally reinforced 3/4" MDF (Medium Density Fiberboard). In an acoustic suspension design, the volume of air inside the enclosure serves as a cushion of air, or air spring, to provide a restoring force for the woofer cone. The air inside the enclosure essentially becomes the dominant part of the woofer's suspension. Since the volume of air inside the enclosure is more linear than the mechanical parts of the woofer's suspension, this enables the woofer's diaphragm to move in a more linear fashion. This also enables the driver to operate at higher excursions with less distortion than more traditional bass-reflex or ported type systems.
