I'm well aware of that. The box isn't very large and one driver sits in a sealed enclosure (higher distortion if used at the lowest frequencies). Adding loads of power adds compression and distortion in many designs. Besides, these two drivers are not neccessarily used together (depends on the mode). And even if they are used together it's still not enough and certainly not equal to what's possible.Well the W371A has one 12" subwoofer in the back and one 14" subwoofer in the front, With 2*400W Amplification, capable of 120 dB peaks with an anechoic F6 of 23Hz.
now EACH speaker has one of these, yet you seem to throw words left and right implying that they're not adequate?
I'm sorry but you need to substantiate your claims of mediocrity of the Genelecs The Ones series.
FIY: A front loaded 15" is equal to something like 3-4 15" woofer in separate large vented boxes and hardly needs any power. Modulation distortion is much lower. Again, just depends what you compare to and references.
The W371A is certainly a clever way to even out the frequency response though. However, it's nothing new and there are several ways to achieve the same or even better approaches, but generelly less market friendly.
Either one understand speaker designs and principles which I've mentioned or one doesn't. It's a simply as that.
