==== Review ============================================
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 (I'll be curious to see if the measurements correlate with what I
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.
Despite being placed between a large RPTV, the DOMUS Grand Pianos managed
to disappear effectively, producing an expansive, transparent soundstage that was
convincingly tall and wide. Even if the measured upper mids prove to be slightly
recessed, the speaker's smooth, somewhat forgiving, yet admirably detailed
presentation makes long term listening exceedingly pleasurable. The balance
makes edgy soundtracks tolerable, while the really good ones still manage to shine.
