when I wound up the volume

to an unsociable level playing

the electronica soundscapes of

Bassnectar's Vava Voom [Amorphous

Music AM0012].

With the 'chillstep' track

'Butterﬂ y' featuring Mimi Page, the

Focus 380 once again served up

satisfyingly deep and articulate bass,

the harsh electronic edge and spitty

high frequencies of the recording

kept moderately in check thanks

There's just one set of high quality

gold-plated multi-way input terminals

provided for single wiring [see text]

to the cleanliness of the speaker's

overall sound character.

Testing the speaker's mettle

with high-resolution audiophile

recordings showed that while it's

not a seductive, ﬂ attering transducer

it does score highly in its ability to

portray the variety of character and

expression in a musical performance.

I was listening to Channel Classics'

delightful recording of Vivaldi's

Concerto in C performed by Rachel

Podger with the Holland Baroque

Society, taken from its La Cetra

SACD [CCS SA 33412]. The image

of the musicians, and the space

they occupied, was noticeably open

and lucid, the build, attack and

subsequent decay of notes all dealt

with in a most lifelike way.

THRILLS WITH HARRY JAMES

Similarly the dynamic contrasts

in Harry James And His Big Band's

Comin' From A Good Place [Shefﬁ eld

Lab CD6] were explosive, the

Focus 380 serving up a thrilling,

seat-of-the pants rendition of this

direct-to-disc audiophile LP. With

'Tuxedo Junction' the speaker proved

perfectly at ease when blasting

out the muted trumpet at a lifelike

sound pressure level, once again its

excellent imaging capability resulting

in clear layering of the band's

instrumentation in the recording

venue. Only a very slight tubbiness

in the lower registers belied the

speaker's modest size and price.

HI-FI NEWS VERDICT

It might not look particularly

sexy, nevertheless the Focus 380

offers fi ne sound quality and can

shift a lot of air if your room can

accommodate its considerable

bass output. It's explicit and

refi ned-sounding in equal

measure, with excellent dynamic

capabilities and vivid imaging

when given space to breathe. It

certainly represents good value,

since to better it you'll need to

spend considerably more.

Sound Quality: 76%

REPORT

DYNAUDIO FOCUS 380

Dynaudio claims 88dB sensitivity for the Focus 380, a

speciﬁ cation which accords well with our measured pink noise

ﬁ gure of 87.8dB. Although this is on the low side for a speaker

of these dimensions it still requires a nominal 4ohm impedance

to achieve it, a ﬁ gure entirely in accordance with our measured

minimum modulus of 3.5ohm. Impedance phase angles are

sufﬁ ciently high to result in a minimum EPDR (equivalent peak

dissipation resistance) of 1.6ohm at 75Hz, so the Focus 380 is a

moderately difﬁ cult load to drive without being a pig. Given the

large cabinet size, the low-ish sensitivity and low impedance, a

bass extension of 44Hz (–6dB re. 200Hz, diffraction-corrected

near-ﬁ eld measurement) may seem a disappointment but

the roll-off is notably slow for a reﬂ ex design suggesting that

transient performance will be clean and room integration

relatively easy. With careful placement relative to room

boundaries it should be possible to extend the Focus 380's

effective bass response to well below this 'anechoic' ﬁ gure.

On-axis response errors of ±3.4dB and ±3.2dB respectively,

200Hz-20kHz, are a good result but the on-axis response trend

is not entirely ﬂ at, with a distinct lowering of output through

the presence band [see Graph 1, below]. This may tend to step

back the stereo image and somewhat soften the sound quality.

Pair matching error over the same frequency range is good

at ±0.9dB. The cumulative spectral decay waterfall [Graph 2,

below], is characterised by fast initial energy decay across the

band and mostly good control of resonances although there

are a few low-level ridges visible from 1kHz up to the low treble

frequencies. KH
