The Ascension F25 is a low wattage, 25 watt, ceramic magnet, guitar speaker with an emphasis on crunch and mid-range presence. A well-balanced driver, equally suited to classic rock sounds as it is jazz, heavy metal or punk.

The F25’s tonal character possesses a detailed, yet reduced, top-end that paves the way for a super-satisfying mid punch to chords and cut-through lead tones without being too sharp or shrill. Clean tones are warm, detailed and not overly bright.

The F25 is great for low powered amps but really comes alive when used with high powered amps in 4×12 configurations or valve amps pushed into overdrive. The unit is also lighter than our Ascension F70 or F90.
