A Celestion Heritage Serving Sound Reinforcement
A historic reference in guitar and bass speakers, Celestion also brings its expertise to sound reinforcement with the TF series. The TF1225E fits this lineage: a transducer designed to deliver solid and balanced reproduction while remaining affordable. It naturally finds its place in passive sound reinforcement cabinets, whether new or as a replacement.
Who Is This Speaker For?
The TF1225E is suitable for contractors, multipurpose venues, rehearsal studios, and skilled DIYers looking for a reliable 12-inch speaker for full-range cabinets, satellites, or stage monitors. Its 8-ohm impedance makes it an easy choice to integrate into mono or bi-amped systems, either as a single speaker or in a dual configuration.
What the TF1225E Brings to Your Speakers
Durability and Operational Peace of Mind
The stamped steel frame and ferrite magnet ensure rigidity, mechanical strength, and thermal stability. The result: a speaker that withstands the rigors of transport and heavy use without faltering.
Tonal Balance and Efficiency
With a sensitivity of 96 dB and a frequency response from 50 Hz to 3 kHz, the TF1225E delivers clean bass and present low-mids, an ideal foundation for an effective two-way speaker. It pairs easily with a compression driver to extend the high frequencies and achieve clear dispersion both front-of-house and on stage monitors.
Easy Integration
Thanks to its 450 W power handling and standard impedance, it adapts to many passive crossovers and existing speaker configurations. It is a relevant replacement solution to bring 12-inch cabinets back to life without compromising reliability.
