A FIVE-STRONG range of coaxial
loudspeakers is at the head of a
host of new arrivals from Italian
loudspeaker manufacturer Eighteen
Sound. Comprising ferrite and
neodymium models, the coax range
leads a charge of launches including
subwoofers and HF drivers.
Designed to deliver extended low
frequencies, the ferrite motorequipped 8CX650 and 10CX650
both boast a nominal dispersion
of 90-degrees. The 2.5-inch LF
copper voice coil employed in their
design utilises the manufacturer’s
Interleaved Sandwich Voice coil
(ISV) technology, while the two
models use a 1.75-inch diameter
HF diaphragm for ‘exceptional’ HF
behaviour. Crucially, the 8CX650 is
also Atmos compatible.
On the neodymium side, the
12NCX750 and 15NCX750 are
described as ‘ideally suited for
compact re ex enclosures and stage
monitors that require substantial
detail and power’. Both transducers
boast a nominal dispersion of
80-degrees and feature a 3-inch
ISV voice coil and 2.4-inch pure
titanium HF diaphragm. Meanwhile,
the 15NCX1000 is classed by the
manufacturer as an ‘Ultra’ offering
due the SPL performance and detail
reportedly derived from its titanium
4-inch diaphragm and dual magnet
motor structure.
Elsewhere, Eighteen Sound has
bolstered its low-end offering,
starting with the neodymium-loaded
18iD. The subwoofer has reportedly
been engineered for ‘maximum
power transfer when operated with
Class-D and similar (iPal compatible)
ampli ers’.
The coaxial 8CX650
The 10CX650
The neodymium 18iD is ideal for
Class-D applications
Designed for vented and band-pass
enclosures, the sub is described as
performing best alongside ampli ers
delivering 2,600W (10,000W peak).
It features a 5.3-inch inside-outside
ISV voice coil, intended to dissipate
heat slowly and effectively, plus a
low-density material air diffractor
placed into the heatsink to act as a
cooling system. In addition, it has
been treated to guard against the
effects of inclement weather.
Similarly, the 18LW2400WP
is an 18-inch extended low
frequency loudspeaker featuring a
waterproof cone assembly. It has
been designed for high SPL sub
applications in either a re ex, bandpass or horn loaded con guration,
and offers higher maximum
SPL, increased programme
power handling and lower power
compression than Eighteen Sound’s
industry standard 18LW1400. Best
results are achieved along side
ampli ers capable of delivering
2,400W programme power without
clipping.
Key to the design is a large
displacement suspension system
which, in conjunction with a
berglass reinforced, straight ribbed
cone and the manufacturer’s Double
Silicon Spider (DSS) technology,
allows an ultra-linear piston action.
Again including ISV with a 4-inch
inside-outside copper voice coil, the
transducer also utilises a proprietary
pulp treatment making the cone
impervious to water.
Continuing with the theme, the
18TLW3000 is an 18-inch sub
that works best in tandem with an
ampli er that can deliver 3,600W
without clipping. It incorporates
Eighteen Sound’s proprietary
Tetracoil Technology, where two
different, axially separated magnetic
a treated polymer suspension, a
1.4-inch exit, and an angled former
edge-wound copper-clad aluminium
3-inch voice coil. Again, it has been
treated for weather resistance.
The 4-inch ND4015Ti2 is
described as ‘the result of extensive
experience with its predecessors in
the ND4015 line’, offering a ‘next
generation titanium diaphragm’
to deliver higher sensitivity and

gaps and two inside-outside 4-inch
diameter voice coils are wound on
the same former and suspended
evenly in the magnetic gaps.
Advantages reportedly include clarity
in the low end and an AES power
The ND4015T2 compression driver
extended high frequencies. It
features a 4-inch edgewood
aluminium voice coil and 1.5-inch
throat exit four-slot phase plug and
is also available in 1.4-inch and
2-inch throat con gurations.
Finally, the manufacturer has
debuted the XG10 line source
waveguide with a 1-inch throat entry.
The waveguide boasts a speci c
line acoustical design intended to
minimise internal re ections and
acoustical losses, while its throat
shape has been optimised to lower
air distortion. It reportedly delivers a
10-degree vertical dispersion angle
while horizontal coverage can range
from 80-degrees to 120-degrees.
The ND1480Be compression
driver
handling of up to 1,800W. Like the
18LW2400WP, the 18TLW3000 has
been treated for weather resistance.
Moving back up the frequency
range, the ND1480BE neodymium
HF compression driver has been
designed for ‘high level sound
system applications requiring critical
accuracy’. The assembly features
a 3-inch diaphragm composed
of a beryllium dome attached to

Beyma leads wealth of launches with MC500 family
SPANISH TRANSDUCER
specialist, Beyma, is aiming its new,
three member MC500 range of
ferrite magnet woofers at low-end
line array and active loudspeaker
applications, incorporating its
proprietary Maltcross cooling
Beyma’s 15-inch 15MC500
ferrite woofer
technology to reportedly deliver up
to 1,000W programme power.
The three models comprise
the 10-inch 10MC500, 12-inch
12MC500 and 15-inch 15MC500.
All three boast 2.5-inch voice coils
with ceramic magnets while the
Maltcross system is also said to
reduce losses due to the power
compression effect.
Also new is the TPL-200, with
X-Bow technology – described by
the manufacturer as a method
for increasing the total SPL of
its pleated diaphragm tweeters.
X-Bow’s inclusion reportedly
delivers increased sensitivity and
greater power within the three
available TPL-200 models.
Two of the TPL-200 models are
being launched with anodised
aluminium front plates (in either
black or metal nishes, named
the TPL-200B and TPL-200S
respectively), for wider horizontal
coverage. A third version, named
the TPL-200H, is equipped with a

constant directivity horn.
Elsewhere, Beyma has announced
two new subwoofers, including the
18-inch 18P1000FeV2, which is
an updated version of its previous
18P1000Fe. The new version
boasts improved power handling
(increased to 1,200W AES), a
redesigned magnetic assembly and
convection circuit for enhanced
ef ciency and low air noise.
Alternatively, the 18-inch
18PWB1000Fe has been designed
for applications requiring more
low-end. It comprises a 4-inch voice
coil design with a ferrite magnet
and can reportedly handle up to
2,000W programme with long
excursion capabilities (12.5mm
Xmax and 55mm peak to peak for
mechanical displacement).
Finally, the manufacturer’s coaxial
family has grown with the addition
of the 10-inch 10CX300Fe, which is
intended for full-range applications.
Offering a useable range of 50Hz
to 20kHz, the ferrite design is
equipped with a PM4 diaphragm
and is described by Beyma as
The 10CX300Fe coaxial
10-inch from Beyma
‘an excellent choice for high
performance bass re ex cabinets’.
