The Belfast 820 provides players and listeners with a well-tailored and satisfyingly clear response. This model gives your tone a defined contour—open and present lows, soft mids, and glassy/articulate highs—that will make your lead and solo lines soar.
Upgrade your 8" guitar speaker cabinet with this high-sensitivity driver, combining a powerful ferrite magnet motor, a 1" copper voice coil, a paper composite cone, a pair of dual terminals for easy connectivity and installation, with a sturdy steel basket to hold it all in place.
