Scottsdale 1220













Alnico guitar speakers have shaped electric guitar tone since the earliest days of amplification. Known for their fast response, warmth, and rich harmonic character, they remain a top choice for players seeking vintage tonal depth. The Scottsdale 1220 embodies this tradition, offering a full-bodied American-voiced tone that excels in blues, rock, and jazz.
This 12-inch speaker is powered by a 34 oz. alnico ring magnet, delivering warm, defined lows, smooth and natural mids, and crisp, glassy highs. Its proprietary edge-doped full paper cone enhances resonance and dynamic response, making it an excellent choice for players who value touch sensitivity and expressive sound.
Key Features:
- 12-inch (305 mm), 20-Watt power handling at 8 Ω impedance
- 99 dB SPL sensitivity for excellent projection
- 34 oz. alnico ring magnet for vintage warmth and dynamic response
- 1.75-inch copper voice coil with a paper former for authentic tone
- Full paper cone with proprietary edge doping for balanced articulation
