THE ALTEC TANGERINE. IT GIVES YOU A NATURAL HIGH.
It may not look like much, but this simple, innocent looking disk brings you closer to the fullest possible sound in the high frequencies. Called the "Tangerine” it's a brand new patented radial phase plug. And we're the only one who has it.
We build it into our high-frequency compression drivers on our Model 15 and 19 speakers. That's why they sound more natural and as close to live sound as you can get.

Until now, the old circumferential phase plugs put up obstacles to high frequencies. By forcing sound through evenly spaced slots, the plug developed its own undesirable acoustic characteristics. Because the distances between slots were even, certain high frequencies never made it through.
That's why we came up with a better idea. Instead of circumferential slots, we have radials. The prime number of the slots and the tapered distances between them provide a clear path to high frequencies. As a result, you get super-high efficiency and greatly extended high frequency response. A much wider band of clear and natural highs, unbroken by any artificial barrier.
After filling in the highs, we created a unique dividing network for our Models 15 and 19. It has a built-in dual-range equalizer so you can achieve variable equalization of mid and high frequencies. The combination of a dual-box design and tuned vent offers precise internal volume and enclosure tuning. The outcome is an unheard-of low frequency response: the best ratio of lower limit vs. sensitivity yet.
It's not surprising that all these improvements in sound technology were made by Altec Lansing. The name that's been the number one choice of professional recording studios and artists for over forty years.
