not needed but here in the most recent Stereophile the kef r700 is reviewed. and here it is in print:
"In the time domain, the R700's step response on the tweeter axis (fig.7) reveals that the tweeter and woofers are connected in positive acoustic polarity, the midrange in inverted polarity. Some Internet know-alls have opined that this mixture of polarities is a problem. It isn't. What actually matters is that the decay of each drive-unit's step smoothly blends with the start of the step of the unit next lower in frequency. In this case, this results in the superb frequency-domain integration of the R700's outputs seen in fig.4. The cumulative spectral-decay plot on the tweeter axis (fig.8) also justifies the adjective superb, as in superbly clean."
having not heard this speaker, i can't speak to its sound as i might hear it. the shape of the impulse response curve in fig.7 doesn't conform to the shape that richard vandersteen prefers. so many of the exotic speakers reviewed in Stereophile exhibit the shape similar to the one shown in this review. some of them i have actually heard and can't fault their sound. usually a direct comparison is not available to me.
i do so love phased array type systems such as the dahlquist dq10, the vandy speakers, the spica tc 50s, and the like. the search for the holy grail isn't likely to be over soon..
