Heritage Series 12-Inch Guitar Speaker

The Celestion G12H Heritage is a 12-inch car speaker rated at 30 watts RMS with a sensitivity of 100 dB. It presents a 15 ohm impedance and a frequency response starting at 55 Hz. This unit suits players seeking vintage-style tonal character for custom cabinet builds.

Ideal for Vintage Tone Seekers.

Guitarists who want thick, syrupy tones with a deep, growling bottom end will appreciate the low-resonance heritage design. The speaker uses a solder-only tag panel and period-correct materials for authentic response. Builders needing higher power handling or modern high-headroom performance should look at alternative drivers.

15 Ohm Impedance Determines Amplifier Matching

The 15 ohm nominal impedance is the critical specification for pairing this speaker with a compatible amplifier output. Mismatched impedance can damage equipment or degrade sound quality. Verify your amplifier supports a 15 ohm load before purchasing this driver.

Questions about this item

What mounting hole pattern and depth clearance does the 12-inch frame need?

The 12-inch frame follows the standard bolt pattern for 12-inch drivers; verify your cabinet cut-out and depth before mounting.

How do I solder the wires to the vintage tag panel without damaging the voice coil former?

Use a temperature-controlled iron, apply heat briefly to each tag, and avoid prolonged contact that could soften the former adhesive.

When should the speaker be reconed or the suspension checked?

Inspect the surround and spider for cracking after several years of high-volume use; recone when distortion appears at low frequencies.
