These are just like new, used under 10 hours, Cabinets are perfect, grills are perfect, will ship in original boxes Sound amazing with my Yamaha Stereo Amp Due to illness and medical bills I am forced to sell these at this time KLH introduces the Model Three as an innovative compact system that rivals the largest of loudspeakers. The mid-century modern Model Three reflects the iconic styling and musical integrity unique to the KLH brand while providing a solution for music enthusiasts with smaller listening spaces. Built on the acoustic suspension design principle and advanced technology the Model Three has very similar characteristics and performance to the KLH Model Five. Don’t let the size fool you. Music will pour out of the Model Threes drivers to command every room big or small.

Unlike most speaker designs today the Model Three does not rely on the stiffness of a conventional woofer’s mechanical suspension to control the motion of its cone at low frequencies. Instead it uses the acoustic stiffness of the air trapped within the enclosure to provide the necessary restoring force. This “air spring” is far more linear than the best mechanical speaker suspension and improves the cone’s ability to make long excursions in order to accurately reproduce the lowest frequencies without distortion. Acoustic suspension designs are regarded all over the world for their greater accuracy tighter bass transients and exceptional bass resolution and texture. CabinetryKLH quality cabinetry is immediately evident the first time you see it. The construction quality that first made us famous is still evident today. Meticulously crafted of genuine West African Mahogany and European Walnut veneer - the 3?4 cabinet is structurally reinforced (front back and sides) resulting in an inert air-tight speaker enclosure. Input/AttenuatorThe Model Three input panel is made from 1/8 aluminum and incorporates a 3-position acoustic balance selector. The acoustics in typical consumer listening rooms can vary widely due to the amount of soft and hard surfaces (such as carpet & furniture) in the listening space. Regardless of whether your listening room is too live or too dead the Model Three gives you the ability to rebalance the loudspeaker so it always sounds its best. WooferThe 8 high-excursion woofer is specifically designed to operate in an enclosure based on the acoustic suspension principle. The extremely low resonance of the woofer gives it very high compliance perfect for use in a closed box design. The woofer features a high current flat-wire voice-coil an aluminum flux stabilizing ring to reduce non-linearities in the magnet assembly and a heavy 5 lb. motor structure all to greatly reduce distortion over large cone displacements. TweeterThe lightweight 1 aluminum dome tweeter combines the virtues of accurate frequency response and dispersion characteristics that are smooth and natural. CrossoverThe heart of the Model Three design is the high-quality thirteen-component crossover network. Where the drivers are the orchestra - the crossover is the conductor. It manages the audio signal and directs the proper signal to the correct driver. The crossover network in Model Three uses 12dB/octave filter slopes on all drive components. This ensures the best possible summation of drive elements over the crossover band. Subjectively the Model Three’s transition from one drive component to the next is virtually seamless and the imaging and definition are much improved. Slant Riser BaseEach Model Three speaker is shipped with an 8° slant riser base made from powder-coated 14-gauge steel - resulting in a very solid and non-resonant speaker base. The 8° up angle ensures the sound is directed properly towards the listener when the listener is seated at a typical listening distance. Grille OptionsThe KLH Model Three West African Mahogany finish comes with Old World Linen grille cloth and the English Walnut finish is sold with Stone Wash Linen grille cloth. These two grille options and the Basalt Black Knit grille are available as Model Three accessories and can be purchased separately.
