Quick Buyer Summary

Why the Altec Model 17 Stands Out

The Model 17 brings Altec’s professional 604 monitor concept into a furniture-grade home loudspeaker. Its Duplex architecture places the high-frequency compression driver and sectoral horn concentrically with the 15-inch low-frequency cone, allowing both sections to operate from a common acoustic center. The result is the point-source presentation, efficiency, imaging, and dynamic response for which classic Altec systems are widely respected.

604-8G Duplex Configuration

• 15-inch low-frequency cone driver
• Coaxially mounted high-frequency compression driver
• Integrated sectoral horn for high-frequency reproduction
• 8-ohm Alnico magnetic system
• Asymmetrical dividing network operating at 1,500 Hz
• Vented cabinet with removable fabric grille

Listening Character

In a properly matched system, the Model 17 typically delivers an immediate, open, and highly dynamic presentation. The coaxial design supports stable imaging and a coherent sense of scale, while the large vented enclosure provides substantial low-frequency presence. Vocals and acoustic instruments are presented with clarity, energy, and lifelike projection.

Actual Cosmetic Condition

This pair presents in excellent vintage cosmetic condition. The cabinets retain an attractive vintage presentation, while normal age-related marks, light scratches, small veneer imperfections, or minor corner wear may remain as shown. Please inspect all product photos closely; they show the exact pair and form an important part of the condition description.

Receiver Compatibility
