And the peak at 250Hz is quite frankly unacceptable for a pro reference monitor. That frequency may be cabinet rattle or resonance, or turbulence due to the narrow channels used for the bass slots.



BTW, have you ever measured the intermodulation performance of your speakers? The Vifas are great, but surely running them for such a wide frequency range introduces significantly more IMD, especially in multitone performance, would it not? I honestly think a better idea would be a slightly larger coaxial driver mounted similarly crossed to dual opposed conventional woofers instead of the fanciful slot loading design. But that'd give us the KEF BladeBTW, have you ever measured the intermodulation performance of your speakers?
