SX Series
Introduction
The SX Series subwoofers are a range of sub bass enclosures designed to complement any of Martin Audio’s full range systems. The range
encompasses ultra-compact sub-miniature subs perfect as a discreet, unobtrusive installation partner to the ADORN or CDD ranges, right
up to very high output twin 18” models perfect for touring use in conjunction with Wavefront Precision line arrays.
The SX Series is suitable for installation or portable applications. Larger models are built to be weather resistant as standard making them
suitable for occasional outdoor use as a portable system or for installed systems as long as they are not directly exposed to the elements.
Larger, heavier models are available with optional castors for touring use to make handling as easy as possible.
Two powered, Dante equipped models are available for any applications requiring an active, networked solution. These are an ideal partner
to the CDD-LIVE range.
A range of accessories are available including eyebolts for flying the smaller models, a flying frame for the twin 18” SX218 and rugged
transit covers.

SX110
SX110
Introduction
The SX110 is a slimline subwoofer designed for applications that call for increased impact and low frequency performance in a visually
unobtrusive enclosure. Its very small size makes it perfectly suited to installed sound applications where space is limited such as under
banquette seating.
It features a 10” (250mm)/2” (50mm) voice coil driver and generously sized low frequency port for reduced air noise. An ideal subwoofer
to augment the bass output of ADORN Series or small CDD loudspeakers, it can be used on the ground or flown using integral M8 inserts.
The SX110 enclosure is constructed from plywood and finished in black or white textured paint as standard. An impact-resistant perforated
steel grille protects the drivers, and rubber feet on the base resist movement.
When used with Martin Audio full-range systems, crossover and EQ functions can be performed by the DX0.5 system controller.

SX110
Connections
The SX110 has a pair of NL4 connectors on the rear panel. These are wired in parallel and whilst one is nominally labelled ‘INPUT’ and
the other as ‘LINK’, connection in and out can be made to either connector. Connection to the drive unit(s) is made to pins 1+/-. There is
no internal connection to pins 2+/- although these are linked together so can be used for example to carry a mid/top signal and connected
to a full range system using a cable wired with reverse connections (pins 2 to pins 1).
Flying SX110
Eyebolts
The SX110 features M8 inserts to allow flown applications using eyebolts. M8 eyebolts suitable for flown systems are available as accessories
from Martin Audio. These are cast steel shouldered eye bolts specifically designed and rated for flown applications. If alternative eyebolts
are used these must be cast or machined products stamped with their SWL. Formed steel non-shouldered eyebolts commonly available
from DIY stores should not be used under any circumstances as they are not sufficiently load-rated for flown applications.
Remove the M8 counter-sunk screws and screw the eyebolts into position. We would recommend three eyebolts and an additional eyebolt
as a redundant safety bond. This should be attached to a different point than the other bolts to support the cabinet in the event of the
other points failing.
Eyebolts should be connected to a suitably rated fixing point such as a girder clamp or a heavy duty fixing such as a sleeve anchor or similar.
They can be linked using suitably rated steel rope or chain and shackles.
Safety note: Flying heavy equipment in public spaces is dangerous and should only be undertaken by suitably qualied and experienced
personnel using adequately rated equipment for the task.

SX210
SX210
Introduction
The SX210 is a slimline dual-driver subwoofer designed for situations that call for a visually unobtrusive enclosure. It can be used singly,
stacked or flown via integral M8 inserts and its ultra-compact size makes it ideal for applications where space is limited. It features dual
10” (250mm)/2” (50mm) voice coil drivers and generously sized low frequency ports for reduced air noise.
The SX210 enclosure is constructed from plywood and finished in black textured paint as standard, with white and RAL colour finishes
available to special order. An impact-resistant perforated steel grille protects the drivers, and the enclosure has twin ergonomic handles at
the rear for easy handling. Rubber feet on the base resist movement and align with recesses in the top surface to assist stacking.
When used with full-range systems, crossover and EQ functions can be performed by the DX0.5 or DX4.0 system controller. The recommended
amplifier is the VIA 2502, or VIA 5002 or VIA 5004 depending upon the size of the overall system.

SX112
SX112
Introduction
The SX112 is an ultra-compact direct radiating sub-bass system designed to extend the bandwidth and increase the headroom of full-
range loudspeaker models. It features a very efficient 12” (300mm) long-throw bass driver with a high power 3” (75mm) voice coil and
generously-sized reflex ports for low noise, high power operation.
With a response of 48Hz-150Hz ± 3dB, the ultra-compact size of the SX112 makes it an ideal partner for ADORN or CDD Series systems
where space is at a premium or where the subwoofers need to be hidden. The enclosure is constructed from plywood and has an impact-
resistant finish, while the driver is protected by a rigid perforated steel grille, which is pre-curved to withstand physical damage.
Finished in black (RAL9005) or white (RAL9016) as standard with integrated flying points, the SX112 can be also be supplied in any RAL
colour to order. When used with full-range systems, crossover and EQ functions can either be performed by the DX0.5 or DX4.0 system
controllers.

SX212
SX212
Introduction
With twin high-efficiency 12” (300mm)/3” (75mm) voice coil long-throw bass drivers and optimally-sized reflex ports to minimise air noise,
the SX212 is the perfect sub-bass where low frequency extension and impact is required from a very compact, unobtrusive, low-profile
enclosure.
The SX212 is designed to be used with full-range loudspeaker systems and extends the low frequency operating range of the combined
system down to 40Hz. The enclosure is constructed from plywood and is internally-braced to reduce energy transmission to the enclosure
panels and baffle. Its perforated steel grille is pre-curved to withstand damage and it can be supplied fitted with optional flying points.
Finished in black (RAL9005) or white (RAL9016) as standard with integrated flying points, the SX212 can be also be supplied in any RAL
colour to order. When used with full-range systems, crossover and EQ functions can either be performed by the DX0.5 or DX4.0 system

SXF115
SXF115
Introduction
The SXF115 is a passive subwoofer designed to extend the performance of Martin Audio WPM and MLA Mini systems down to 42Hz.
Featuring a powerful, long excursion 15” (380mm)/4” (100mm) voice coil driver in a very compact bass reflex enclosure, it can be flown
as part of a WPM or MLA Mini array, or ground-stacked separately.
The design of the 15” driver maximises output while minimising power compression and distortion, and four reflex ports reduce air noise at
very high output levels. The SXF115 enclosure is constructed from multi-laminate birch ply, finished with a durable polyurethane coating
and equipped with a perforated steel grille, skids and twin bar handles. An M20 threaded fitting in the top surface facilitates pole-mounting
of up to 4 WPM or MLA Mini enclosures.
Being a passive subwoofer, the SXF115 is ideal for flown WPM or MLA Mini fixed installations where ground-based, rack-mount amplification
is preferred — either for ease of servicing, increased IP protection, or reduced visible cabling in the air.
When used with a WPM or MLA Mini array, Martin Audio iKON amplifiers or the MSX rack-mount power plant respectively deliver the
correct drive characteristics to the SXF115, with onboard DSP presets for a variety of system configurations. Cardioid operation can be
achieved by arranging the SXF115 in forward and rear-facing pairs.
By adding the input board cover accessory, the subwoofer is fully weather resistant and suitable for permanent outdoor usage.
