How Audio History is made.
A lot of speakers claim to be audio breakthroughs. Our new Model 14 really is. In fact, it's so unique, that before we could create it, we first had to invent a whole new family of components.
We began with a new type of horn. The Mantaray. It's the first "constant directivity" horn ever created. Conventional horns, cones and domes (including so called omnidirectional and reflective speakers) tend to "beam" , that is, narrow their angle of sound radiation at higher frequencies. This effect causes the stereo image to lose strength off the center axis and to actually wander.
Mantaray, on the other hand, 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 most solid three-dimensional stereo image you've ever heard.
And since the sound doesn't diminish off center axis, the Model 14 enlarges your listening area, your "stereo sweet spot". As an extra benefit, Mantaray's precise sound focusing means your music goes in your ears- not in your drapes, walls and ceilings. Consequently, it's more likely than other speakers to sound the same in your home as it does in your dealer's showroom.
Then to give you even higher high's, we developed the first radial phase plug, the Tangerine? ** In contrast to conventional phase plugs with two equidistant circular slots that block some frequencies, the Tangerine's tapered slots permit a free flow of high frequencies to beyond 20 KHz.
Equally important to all this is our new Automatic Power Control System.
Unlike fuse-type devices or circuit breakers, 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. It's quite a system.
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. So that's how audio history is made. And it's all yours at a price that means the best sound value available for your home today.
