TT Diffusor 12" - Standard

Building on the popularity of our G12C, we developed the G12Q for those times when you want the speaker to add some natural, vintage breakup but maintain clarity.  With a 20 oz magnet and a 1" voicecoil, the G12Q definitely has a vintage American flavor.  We highly recommend it with 5E3 style circuits.

Combining decades of experience with advanced measurement and analysis, the V-Type has been built using a carefully balanced 'recipe' of old and new design techniques. It produces a heady, exciting modern vintage sound that just makes you want to keep on playing: a speaker that delivers authentic Celestion tone whatever your style.The V-type is a sweet sounding speaker with a superbly balanced tonal signature that imparts a vintage musicality to your tone. Clean sounds are true across the lows, mids and highs, with just enough upper-mid chime and HF sparkle to add clarity and definition. Crank it up for a sizzling overdrive and raw rock tones, with plenty of mid-band warmth to give body and substance to lead note playing.

The original G12M of the 1960s was Celestion's first guitar speaker to use a ceramic magnet and paved the way for high power guitar amplifiers. The G12M uses a medium weight magnet to produce a sound that is smooth and warm but bright enough to hold its own against any rock backline.Known simply these days as the 'Greenback', the G12M's fabled 'brown tone' is characterised by a warm, controlled low-end, a rich, vocal mid-range and a delicate, detailed top-end. Loaded into a 4x12 and driven hard, these speakers exude warm, crunchy chords and sweet searing single-notes

Universal size for 12" speakers
Dome diameter: 120 mm - recommended for guitar loudspeaker with massive beaming and higain sounds

As the frequency increases, the radiation of a loudspeaker is increasingly focused on its center. If the listener is in this beam, the sound is extremely harsh and biting; if one moves to the side of it, the sound becomes significantly darker and treble components are partially missing.
To reduce this behavior, a diffuser is used. This sits directly in the beam of the speaker and deflects the high frequencies very strongly, it breaks the "beam". This makes the sound much fuller and more balanced.
