The DOMUS Grand Pianos
The big, three-way DOMUS Grand Pianos do cost more than the Concert series Grand Pianos they replace, but they are so much more capable in every way. Where the original was a two-way with a passive radiator, the new design is a ported three-way that plays louder without strain, is far more dynamic at both ends of the scale, and extends far lower in the bass. Sonus suggests running them full range in a 5.1-channel system and that's what I did. I also found that the familiar ring radiator tweeter here provided far smoother high frequency response than the slightly excessive top end of the older Grand Piano. In addition, while the original Grand Piano's silk dome tweeter featured a rather steep suck-out in the vertical axis, making listening height and/or speaker front baffle rake angle critical, the ring radiator's smoother off-axis vertical response makes the overall high frequency balance of the DOMUS far less dependent upon the height of the listening position and/or the speaker's rake angle. 

So, both cosmetically and sonically the new DOMUS Grand Piano represents a big step up from the original. The tonal balance has more in common with the more expensive Sonus faber speakers than with the original Grand Piano. The DOMUS Grand Piano features a smooth, extended top end, a slightly suppressed but pleasing upper midrange, and a very sweet, smooth, well-balanced midrange, which is a Sonus specialty 

The original Grand Piano was good down to around 40Hz, below which response dropped off admirably, free of any attempted "bumps" suggesting more bottom end than there really was. The three-way DOMUS Grand Piano clearly extends lower, and is more effortless in doing so. More importantly, top to bottom driver integration is exceedingly well done, with no seams sticking out. In this regard the DOMUS Grand Piano is a major improvement over the Concert series Grand Pianos.
