![]() On paper the vented alignments -3dB point will look deeper, but the sealed speaker compensates with a more extension below roll-off. This frequency (quoted as the -3dB point for the bass extension) is somewhat higher than a vented alignment, but the roll off below a vented speaker’s -3dB point happens at 24dB/octave. Low frequency performance is accurately damped delivering a tight impulse response – the time the driver takes to stop moving after the signal has passed is very short – and rolls off at the natural sealed box rate of 12dB/octave below the combined box and driver resonant frequency. All Arendal speakers start with an optimal, low Q sealed box designs.
