I was so impressed with the Rega R1, Rega’s
$495 per pair mini-monitor, (the entry level
of their new “R” Series of loudspeakers,) that
I’ve made it my new Budget Reference – a
speaker that all other speakers, regardless of
price, have to outperform in order to justify
their existence. (See my review
here) The R1’s combination of
superb music-making skills, high resolution
and surprising bass response makes the Budget
Reference concept a very useful tool for
evaluating other speakers. If they can’t
musically outperform the R1, especially if
priced stratospherically, why bother?
The R1, like all excellent mini-monitors, can
be the simplest and most guaranteed way of
extracting all that stereo reproduction of
music can achieve. Set up correctly in small
rooms, mini-monitors can create the most
accurate, convincing, and spectacular stereo
illusions, supplemented by the natural
transparency and revelation of detail that are
the forte of near-field listening. The biggest
hurdle in successfully utilizing a
mini-monitor into all but the smallest of
rooms is the problem of limited bass-response.
Small woofers have inherent limits, and the
mini-monitor concept presupposes small room
applications, the dimensions of which serve to
reinforce and boost the speaker’s inherent
tailing off of bass response. If the room is
too big or the speaker’s position is not
optimum within it, the whole effort collapses.
Too often users find themselves yearning
desperately for just a few more Hz on the
bottom end to complete the illusion of
full-range music. It can be hair-tearingly
maddening to have nailed the set-up of a
mini-monitor system only to have it flounder
for lack of just a few notes on the bottom
end. “Please, oh, please! Just another
half-octave!”
34-years’ experience in the audio world have
taught me that the most common system building
error is mismatching the speaker to the room.
Place a mini-monitor in too large a room and
you get the bass-shy “squawk box” syndrome.
Far more common in the US is buying a speaker
whose bass response is more than the room can
handle, resulting in various manifestations of
boom, thud, and rhinocerine mud-wallowing.
It’s more than a simple matter of room
dimensions and overall volume: wall and floor
construction also play a crucial role. It’s
been my general experience that if you can get
clear and tight response down to 40 Hz
in-room, stop and count your blessings. And
think very hard about pursuing response into
the bottom octave. One is more likely to screw
up everything achieved in the musically useful
range of 40 Hz and above. While my own
reference speaker, the Sound Lab Dynastat, is
flat to 20 Hz in my large basement listening
room, the number of times I’ve absolutely
needed that bottom octave for musical reasons
in the last two years is zero. While the
lowest range of the organ might be majestic in
a large cathedral, mismatched bass-heavy
speakers that literally shake the house on its
foundations are more likely to induce vertigo
and viscera displacement than aesthetic
satisfaction. So how do you walk the line
between bass-shy mini-monitors and elephantine
bass heaviness in the “normal” room? Enter the
new Rega R7 loudspeaker.
Rega’s new “R” Series of speakers descend from
the genetic pool of the R9 - Rega’s $3995 per
pair flagship speaker. The R7 is most closely
related to the R9, sharing its
transmission-line woofer loading (the R1, R3,
and R5 use the bass-reflex method,) and
derives its midrange driver and tweeter from
the R9 as well. The R7 is physically smaller
than the R9, does not share its room tuning
feature or ultimate low bass response, and
does not mount its crossover circuitry outside
the cabinet. Rega designed and manufactures
all the drivers in the R Series; the entire
speaker is manufactured by Rega in England.
This contrasts strongly with the more common
speaker industry practice of using OEM raw
drivers and using Chinese slave labor for
manufacture (do contemporary Chinese
industrial workers feel ironic pride from
their unique situation of being enslaved and
exploited by both Capitalism and Communism
simultaneously?)
The Rega R7 sells for $2495 per pair. Given
the R7’s custom bespoke drivers, the
sophistication of its design, its
transmission-line woofer loading, and the
first-rate cabinetry and construction quality
typical of UK-built speakers, the price is a
give-away bargain. Most unusually, the US
price is actually a bit less than the price in
the UK. Rega remains faithful to its ideals:
building deeply musically satisfying products
which real-world music lovers can actually
afford to own. No preposterous ”High End”
pricing to impress the naïve here.
The R7’s wood-veneered cabinet measures 38.25
inches high by 13.7 inches deep by 10.6 inches
wide. This pattern of relative dimensions has
become an archetype of contemporary speaker
design: the narrow front panel eliminating
driver output diffraction and delay from the
front baffle, the depth of the cabinet
permitting placement close to a rear wall, and
the small overall footprint leading to easy
aesthetic incorporation into the average
living room. Like all the R series speakers,
the midrange driver is located at the top of
the front baffle with the tweeter just below.
On the R7 these are attached to a black,
plastic-looking plate that then attaches to
the cabinet. A removeable black grill covers
the two drivers. Two/thirds of the way up on
the side of the cabinet are mounted the
side-firing 7-inch woofer and the port for its
transmission-line loading. The woofer features
a 6-layer aluminum voice coil that allows Rega
to run this bass driver up to its limit of
around 800 Hz without the need for a
crossover. Most unusually, there is also a
reflex port for the 5-inch midrange driver.
Another black grill covers the woofer and
ports.
The R7’s small footprint is enlarged by
bolt-on metal outriggers into which are
screwed 4 supporting spikes. These outriggers
appear to mimic cantilever bridges and look
like they might offer some vertical isolation
properties. Rega claims a nominal 6-Ohm
impedance (which usually implies some dips
into lower impedances) and approximately 89 dB
sensitivity. Double speaker posts permit bi-amping
and bi-wiring. Like many speakers built for UK
and European listening rooms, the R7’s can be
placed near a rear wall without exaggerating
the bass response. The side-mounted woofers
should face outwards. I set them up well away
from the rear wall, with distance between the
speakers greater than the distance from my
listening chair. Speaker toe-in was not
critical. The R7 is an elegant and low-key
presence in the listening room.
Burn-in from new took a week’s play. I
measured the speaker’s response in my large
basement reference room at my listening chair
in stereo. The speaker was far enough into the
room (about half way) so that there was no
bass reinforcement from the speaker’s rear
wall. The midrange/tweeter response was
extremely linear, extending out to 16 KHz (I
don’t much trust the measuring accuracy of my
devices at the extreme top of the frequency
range) at the ear with no deviations. It was
much flatter than the response of the R1,
which showed a minor elevation in the 2-6 KHz
range, and was flatter than any other speaker
I’ve measured. I consider measurements as a
rough indicator rather than a predictor, and I
am not ruled by them. After all, they can only
indicate quantity; they say nothing about
quality. Although the special mid/tweeter
drivers of the R9 and R7 look superficially
similar to those in the 1, 3, and 5, they are
clearly quite different in neutrality and
linearity. Bass response was flat to 40 Hz,
thus meeting my criterion for the speaker to
be considered full-range. Given the tuning
frequency (mid 40’s) of the transmission
line’s port, it was obvious that Rega designed
the R7 for bass quality rather than for
sub-bass quantity.
Rega uses music as the final arbiter for all
their designs and has long been known for
consistently getting the heart of music
right. Critical auditioning and extensive
listening tests while playing real music
determines if the product passes Rega’s
muster. While other audiophile, high end, and
‘designer’ audio firms claim to do the same
(is there any more pretentious blather than
that about “voicing?”), one wonders by the
results if their musical criterion is
listening to Mantovani, Muzak, and Barry
Manilow (supplemented by occasional cannon
fire) recorded in Grand Central Station. Rega
is a far hipper company: you can listen to
Mozart and the Meters, Beethoven and the
Beatles, Cream and Coltrane, Bach and Captain
Beefheart, and be confident you’ll “get” the
musical message.
Rega designs each of their products to mate
optimally with other Rega components. There is
no point designing a loudspeaker with superb
rhythmic articulation, subtle dynamic shading,
and tight precise bass if it’s going to be
played with an arrhythmic turntable or CD
player, and an amplifier with flabby and
uncontrolled bass. I appreciated again, in my
review of a complete Rega system (see:here)
how well this system approach of Rega’s works.
It’s like a fine fitting glove where all the
fingers cooperate with the action of the hand,
resulting in an organic and coherent musical
presentation that has one responding to the
music rather than to the sound. First time
auditioners of the R7 should make a point of
having them demonstrated within a Rega system
context to guarantee fully hearing the
intention of their design.
This is not to say that the R7 is incompatible
with other than Rega products, as my
auditioning experience with a wide variety of
amplification, sources, and cabling showed.
Central in choosing matching components for
the R7 should be, obviously, the criteria of
rhythmic acuity, precise and tight bass
response and a fundamental fidelity to the
devices of music making.
The immediate impression of the R7 is that of
an extremely fast, highly agile and highly
detailed sonic presentation, where the 3
drivers cohere into one entity that can start
and stop seemingly instantaneously. The
placement of the tweeter below the mid/woofer
on the front panel (used in all the R series)
creates a slight displacement in arrival times
at the ear between the two drivers. With one’s
ears on the plane of the mid driver and above,
the tweeter integrates in time so well it
sounds like one driver doing all the work.
High frequencies and overtones emerge from the
body of the instrument rather than from a
detached plane above it. Percussion
instruments are very clear: one can hear the
sound of a wooden stick creating that slightly
woody sound before a cymbal explodes into its
metallic shimmer. More importantly, one can
hear the rhythmic patterns played on the
cymbals, along with subtle dynamic changes and
accents. This placement of ‘tweeter below’ is
a simple and clever solution to the problem of
time coherence: no need for complex
compensation in the crossover or for sloping
baffle cabinet designs.
Probably the most striking aspect of the R7 is
its simply stupendous bass clarity. While I’ve
always been a bass lover, I’ve never been a
bass freak or a bass slut. No perverted
one-note bass boom, mud and thud for me; nor
will just any type of sleazy and promiscuous
bass performance do. I want faithful, clear,
and precise renditions of individual bass
guitar notes down to the bottom of the
instrument’s frequency range; I want the
rhythm and swing clearly marked out; I want to
hear ‘tunes playing in the bass.’ On
orchestral music I want to hear the difference
between the double bass and the cello. I want
to hear the kick drum clearly differentiated
from the floor tom-toms. I want to hear the
polyrhythmic complexities of West African and
Middle Eastern Music. I want to know precisely
what the contribution of the bass instruments
are to the whole of the musical proceedings. I
want to dance.
