Celestion G12M Greenback 16 Ohm Altoparlanti per chitarra / basso 16 Ohm

Classic British Guitar Tone in a 12-Inch Replacement Speaker

The Celestion G12M Greenback 16 Ohm is a 12-inch guitar speaker engineered to reproduce the warm, mid-forward character that has shaped British rock tone since the 1960s. It delivers a loud, assertive voice that pairs naturally with valve amps pushed into overdrive.

Ceramic Magnet Heritage and Controlled Top-End

What sets this driver apart is its voicing: a broad mid-range attack combined with a restrained, rolled-off top end that keeps high-gain tones free of fizz. A pressed-steel chassis anchors the motor assembly for the focused response associated with classic Marshall-style cabinets.

Power Handling and Impedance — Match Your Amp

The 16-ohm rating matches amps wired to that load, and the 25-watt continuous power rating suits low- to mid-powered tube heads.

• Power Rating: 25 W — handles low- and mid-powered valve amps comfortably
• Nominal Impedance: 16 Ω
• Sensitivity: 98 dB — lively output that preserves pick attack and dynamics

Voice Coil, Magnet, and Chassis Construction

A traditional round-copper voice coil on a 1.75-inch former pairs with a 35-ounce ceramic magnet for the controlled low end and articulate mid-range that define this model.

• Voice Coil: 44.5 mm round copper — classic compression and growl on overdrive
• Magnet: Ceramic, 0.99 kg (35 oz)
• Chassis: Pressed steel — rigid frame that resists flex under high SPL

Frequency Response and Mounting Dimensions

Standard 12-inch cut-out and four-slot mounting pattern make installation straightforward in most combos and extension cabinets. At 3.6 kg, the unit suits both combo and head-cabinet use.

• Frequency Range: 75–5000 Hz — focused guitar-range voicing with rolled-off top end
• Resonance (Fs): 75 Hz — anchors low-end response for tight chording
• Cut-out Diameter: 283 mm with Mounting Slot PCD: 297 mm — standard 12-inch fit
