2/ PRODUCT OVERVIEW

The Altec Model 15 is a classic American two-way loudspeaker system combining a 12-inch low-frequency driver with Altec's distinctive horn-loaded compression-driver technology. Developed as part of Altec's home loudspeaker range, the Model 15 brings together professional loudspeaker engineering and traditional wood-cabinet styling.

The high-frequency system features Altec's radial phase plug compression driver, coupled to a curved radial horn. This design was developed to improve high-frequency extension and dispersion. The manufacturer specifies a frequency response of 30 Hz to 20 kHz and a crossover frequency of 1,700 Hz. A vented enclosure supports the 12-inch woofer, while separate midrange and high-frequency shelving controls allow adjustment of the speaker's tonal balance.

This HQaudios pair features brown wood-grain cabinets, distinctive Altec Model 15 identification badges, front-mounted woofers, rectangular horn openings, and separate midrange and high-frequency level controls. Our service work included attention to the speaker foam components and reassembly. The actual pair is pictured in detail, including cabinet surfaces, front drivers, control panels, and rear connections. Visible differences in cabinet color and remaining signs of age are reflected in the product photographs.

3/ HQAUDIOS RESTORATION & TESTING

Speaker Reassembly: We reassembled the serviced speaker components following the foam work.

After Restoration / Final Testing
