These lovely modest standmounts look worth a listen . many of you know Paul , his stuff is quite exceptional and these are only 1750 new which is rather a bargain imho apparently they dont need a sub . 90db sensitivity specs The new RFC Rubato is a medium sized stand mount loudspeaker with some remarkable qualities. Firstly, it is based upon a new production 6.5 inch coaxial loudspeaker. This comprises a central silk dome tweeter in its own wave guide horn loaded section, utilising a neodymium magnet. The tweeter is coaxially mounted within a 6.5 inch midwoofer giving a true point source image, both phase and time aligned.
The cabinet is a beautifully crafted high quality veneered Baltic birch ply enclosure which houses the point to point crossover. It is front port loaded for exceptional bass extension for its size and ease of placement. This makes for a rigid low colouration cabinet, internally damped and braced also housing the internal point to point hand assembled crossover, designed by RFC to achieve a low distortion phase correct and linear response.
The Rubato exhibits superb smooth off axis controlled directivity to 60 degrees free of the usual polar response waists for a smooth stable off axis image. It is a highly musical loudspeaker with exceptional imaging abilities allowing the speakers to disappear whilst throwing a broad and deep sound stage.
This little speaker offers quite remarkable performance with useful bass to 42 Hz and can be used nearfield thanks to the point source imaging as well as far field for conventional home hifi use. Sensitivity is excellent at close on 90dB/1w/1m and it is an easy benign amplifier load with a nominal 8 Ohm load (easy to drive).

If the driver performance is good enough, the coherence of a concentric design should be nice. I had a design years ago whose xover design and time alignment gave a really coherent top to bottom sound. The size is enough so the bass should be decent for a standmount.
