Building on the success of our innovative R1, the Resolution 1.5 is a 2-way loudspeaker enclosure with 90 degree dispersion, high-fidelity and good low frequency output for its size.  Our unique axhead-loaded 5” cone loudspeaker is combined with a substantial 18” bass driver to present a highly capable two way enclosure.  In common with the Resolution 1, the 5” eliminates the need for compression drivers with their inherent harshness and distortion.  The 5” driver’s ability to operate cleanly down to a low crossover point of 590 Hz allows the transition to the bass driver to be exceptionally smooth.  Furthermore, our bass loading technology enables use of an 18” driver in an enclosure size where previously only a 15” loudspeaker could have been used.  As usual with Funktion One there is no system EQ and the resulting sound is extremely involving. It is well suited to applications needing a single enclosure per side including theatres, entertainment venues and worship spaces.
