Request product informationTHE F1501 APPROACH
One driver. No box. Pure music.
F1501 takes a 15-inch full-range driver and sets it on an open baffle, free of cabinet coloration and standing-wave interference. There is no crossover and no enclosure to get between the music and the listener.
The result is a wide, deep soundstage with the naturalness of a single point source — open, precise and easy to live with for long listening.
02
Full range, no crossover
A single full-range driver covers 41.5 Hz to 20 kHz. With no crossover and no signal splitting, phase remains coherent, and voices and instruments appear vividly in place.
03
155 mm magnet, 35 Hz resonance
A large magnet and long-excursion design, with a 35 Hz resonance frequency, give the open-baffle system clean, agile bass that is deep in texture and quick in recovery.
04
Vita pulp cone
An integrated Vita paper-pulp diaphragm with a rubber surround reproduces vocals and strings with a warm, natural character, low distortion and a fatigue-free presentation.
05
Open baffle, no box coloration
The cabinet-free baffle eliminates box coloration and standing-wave interference, opening the soundstage in both width and depth.
OPEN-BAFFLE STRUCTURE
Support without a box.
A labyrinth-inspired support geometry holds the baffle rigidly, preserving structural integrity while leaving the acoustic path open and uncolored.
