The single sub, the TENi, when used with the MODULAR FOURTEEN – a low frequency effect divider – functioned as the
bass (drivers) in the three-piece audio system reviewed in our last issue. It can also be the single subwoofer for HT
application. The MODULAR EIGHTs can serve as stands for models TWO, THREE or FOUR. Including a separate powered
subwoofer and a centre channel, the series offers six models altogether, which can be interchanged to customize sound
for either two-channel audio or home theatre systems.
These speakers represent a blend of design expertise, practicality and adaptability, which shows the designers’
consideration for the consumer and his/her environment. All this may sound a little perplexing, but actually makes matching
the right model to a room and or personal preference less difficult. Now to the loudspeakers’…
Appearance:
All models conform to the look of traditional loudspeakers-rectangular enclosure-in various sizes ranging in height from
10.75 inches for the MODULAR TWO to 31 inches for the MODULAR EIGHT. Depth ranges from 10 inches for the
MODULAR THREE and FOUR to 16 inches for the MODULAR EIGHT (the largest speaker with side firing woofers). The
powered subwoofer, the MODULAR TENi, measures 13 inches wide, 17 inches deep and 16.5 inches high. The baffles are
finished in Lamineer™ - a powder coating process for MDF which results in a very hard finish that assures lasting gloss.
Our samples were finished in black ash, though a light maple finish is also available. Cabinet finishing is beyond reproach
and will enhance almost any décor.
c
Technology:
All enclosures are constructed with high-grade 19mm MDF on three sides. For the baffle, which accommodates the drivers,
a thicker 25mm MDF is used for greater stability. The above mentioned Lamineer process on the baffle limits diffraction.
Angstrom employs a new fibre glass Pentacone 112mm woofer which features non-resonant system coupling (NRSC).
This woofer was designed in cooperation with the Danish manufacturer Vifa and offers double vented baskets, vented
voice coil formers and an ultra light rigid cone, said to provide 30 to 40 percent greater excursion.
Vifa also makes the 19mm woven silk dome tweeter which features ferro fluid cooling and frequency extension to above
25kHz.
The crossovers are first and second order Butterworth designs with polypropylene capacitors and air core, non-inductive
resistors. The MODULAR EIGHT (the largest speaker with built-in bass amplifier) has a side-firing 20.4cm powered
woofer. The EIGHTs can be used as a single sub. Two, for left and right channels and, as mentioned earlier, can be used
as stands for the TWOs, THREEs or FOURs. The amplifier delivers 120 watts and features Darlington output devices made
by Texas Instruments. The MODULAR TENi (the other stand-alone subwoofer) is an isobaric design with two polymer-
coated 25.5cm woofers. We used this one for our last evaluation and it differs from others currently on the market by
offering a true 120 watts (rated over a frequency range from 20Hz to 20kHz). This power ensures that the amp is never
taxed by dynamics in the range where it is functioning (from 30Hz to 180Hz). This power ensures that the amp is never
taxed by dynamics in the range where it is functioning (from 30Hz to 180Hz). Only about 25% of the amplifier’s power is
commonly used, guaranteeing that it will never “clip” (run into distortion).
The Sound:
We used two MODULAR EIGHT (powered subs), placing first the MODULAR THREEs and later the Modular FOURs on the
subs, decoupling them with Blue Tack, Nordost Red Dawn interconnects and speaker cables were used to connect an
Onkyo A/V Receiver, a Sony VCR and an Elite DVD player. Thus we had loudspeakers priced at $799/pair for the THREEs,
$879/pair for the FOURs and $1,558 for a pair of EIGHTs. The MODULAR SIC C centre channel speaker for $339 was used
with both combinations. For our surround channels we also used the THREEs and FOURs on small stands.
We set up the subwoofers with the main enclosures stacked about ten feet apart with the center channel SIX C in slightly
angled upwards. The Onkyo receiver (rated at 80watts/channel) supplied the power and delivered considerable slam. The
Angstrom Modular speakers provided excellent, first-class transparent sound, including that graceful touch of refinement
not commonly found in this modest price range. In addition to musicality, bottom-end whack and loudspeakers’ ability to
deliver an astounding sound stage, we all noted the centre channel speaker’s effortless blend with the fronts. Centre
channel information (derived from parts of the front channel data) was as clear as the proverbial bell - a very important part
of an HT set-up as it must handle almost all dialogue. Pure midrange integrated well with frequencies above and reached
well into the upper bass/lower midrange. As the bass is handled by the powered sub-woofers, we adjusted the crossover
to about 85Hz and turned up the gain to suit the auditioning room’s acoustics. After a few adjustments, the bass blended
very well indeed and the separate enclosures didn’t divide the film sound information at all. Rather, the system defined the
stage on which the action took place. With the MODULAR THREE loudspeakers, the system delivered upper frequency with
respectable body, enough “air” and plenty of finesse when handling complex and subtle film-sound information. With the
MODULAR FOURs, texture improved, high frequencies smoothed out a little and, though the tonal differences were
negligible to be sure, the overall sound was a little richer and the tonal balance a touch more refined. Imaging and overall
resolution was excellent and continued when we changed models. The bass integrated very well with both models but
needed small adjustments to accommodate speaker changes. Both system configurations delivered excellent imagery
and first-class focus which complemented the on-screen action. And, for those who use an HT system for music listening,
it also offers musical delights. The surround channels provided the same sonic characteristics as the front speakers,
minus deep bass extension. Additional subs can be added to realize the full frequency range in surround channels. We
didn’t audition this configuration, but we assume that the only audible difference would be additional bottom energy for
those who love bass, although we feel this is hardly necessary. We auditioned the system using only one subwoofer-the
model TENi - in the active mode, which resulted in a little less “weight” at frequencies below 80Hz, but certainly sufficient to
hear bass - loud and clear.
Synopsis & Commentary:
As we said in our last issue, Angstrom appears to be on the right track when addressing issues relating to room acoustics
and proper set-up procedures - and we applaud them for their efforts. The company offers an expansive guide to assist
retailers and consumers to coordinate speakers, electronics and the listening environment. The guide is the key to the
correct set-up procedure of loudspeakers for home theatre or two-channel audio and includes recommendations based on
the size of the listening room and the electronics one should consider for a system. More facts are obtainable from
Angstrom dealers or from the company direct.
Our own experience with retailers has often been disappointing, because, even though they are informed by
manufacturers, they do not always demonstrate properly or follow correct techniques. Making logic-based decisions for
loudspeakers for HT, or any other system, isn’t easy, especially in a cluttered shop where components and loudspeakers
fight for display space. It is for this reason, that we recommend Angstrom’s set-up system help – it will make things a bit
easier.
The reviewed systems(s) - here in a home theatre set-up - show how a conscientious approach to system synergy and
environmental issues can stretch dollars and achieve superb sound. The Angstroms can be used with modestly priced
electronics with excellent results, but if high-end HT components are employed, these speakers will deliver astoundingly
accurate and musically pleasing sound, as the system quickly complies to upscale electronics. The Angstrom system is
an outright bargain, not easily outperformed - if at all - by loudspeakers in the same price range.





Product Review
In our last issue, we reported on Angstrom’s Modular system in an audio
set-up. At that time we promised to continue with an evaluation using the
Modular arrangement in a home theatre system. Before we get to the nitty
gritty, we’ll do a short recap. Angstrom loudspeakers were introduced
almost five years ago and though they manufacture many models
nowadays, it all began with the modestly priced Omega 5 (reviewed in Vol.
10 #3) bookshelf speakers. About a year later, the company introduced their
flagship Obbigato speakers (reviewed in Vol. 11 #1) and both were highly
rated. The company’s latest offering - the Modular series are under review
here.The line includes the models MODULAR EIGHT and TENi subwoofers
which can serve as the cornerstones for an entire HT system. Either of the
two models can be employed with the MODULAR TWO, THREE or FOUR
loudspeakers.
