We Speak Your Tone 
Boston 1020 - 10 Inch Alnico Guitar Speaker, 20 Watt, 8 Ohm
GOTTA GET BACK TO THE REAL NITTY-GRITTY...
Create your next signature sound with the Boston 10-inch guitar speaker. Spotlight your tone with a driver delivering warm, articulate bottom-end, scooped mids, and blooming highs.
This model includes a good old-fashioned 60s-style Alnico magnet assembly for an ultra-quick impulse response. The often misunderstood magic of Alnico is that it partially and temporarily demagnetizes when you push them hard, applying a simple compression effect that adds a satisfying sense of sweetness that can’t be beat.
