Paradigm Reference Studio/100 v.2 loudspeaker Measurements part 3
In the time domain, the tweeter and midrange outputs are in negative polarity, as can be seen from the step response (fig.8). The lazy positive-going part of the trace at 4.5ms is due to the positive-polarity woofers. Note that the crossover and the time delay ensure that each drive-unit hands over smoothly to the next lower in frequency in this graph, which correlates with a smooth, flat frequency response. The cumulative spectral-decay plot (fig.9) is very clean, other than some low-level delayed energy at the top of the midrange unit's passband.

As we have come to expect from Paradigm, this is excellent measured performance at a very competitive price.—John Atkinson
