Vintage Altec Lansing Speakers.  This model, Model 14, was the first speaker with a new type of horn, The Mantaray. It's the first "constant directivity" horn ever created. This horn delivers a clearly-defined sound wedge that keeps its strength regardless of the music's changing frequencies.You get the full spectrum of sound and the solid three-dimensional stereo image. The first radial phase plug was developed, The Tangerine, is also standard with this model. The Tangerine's tapered slots permit a free flow of high frequencies to beyond 20 KHz. Equally important to all this is the new Automatic Power Control System. The system keeps track of the power pumped into the speaker, lets you know with a blinking light when power exceeds safe limits, and then reduces overloads automatically, but without shutting the speaker off. In addition, the Model 14 offers you super-efficiency, high-power handling capacity and exceptional dynamic range, plus a new vented enclosure with a 12-inch bass driver for a tighter, crisper low end.
