A for Aalborg and… – … Børresen's new A range spanning the models 1-3 in satin walnut or black ash. The 5-inch mid/woofers are a new design sandwiching an aramid honeycomb core between carbon-fibre skins whilst the motors are ferrite with dual copper caps to lower inductance. The tweeter is the brand's familiar planarmagnetic operating above 2.5kHz. The bass loading is described as different from classic bass reflex to avoid resonant peaks. Once again paralleled mid/woofers become 2½-way not 3-way affairs. The A1 promises 45Hz-50kHz bandwidth with impedance above 6Ω. The A2 with its twin 5-inch drivers adds 10 cycles to 35Hz. The four-driver A3 adds another 10 cycles for an F3 of 25Hz.
