1. SAFETY
It is imperative that electro-acoustic speakers are used in full compliance with safety regulations. Professional electro-acoustic systems
are capable of producing high levels of sound pressure, and must
therefore be used with care. Loss of hearing is cumulative, and may
result after exposure for long periods at sound pressure levels above
90 dB. Never stand close to the electro-acoustic speakers working
at high volume. For ground positioning, always check that the base
is flat and stable. Do not pile speakers up too high in outdoor areas,
where the wind may cause the stack to become unstable. Suspended systems must be assembled by qualified and experienced staff
and professional riggers.
2. GENERAL INFORMATION
The Deflector Line consists of 12 models, (8 speakers + 4 subwoofers), including the self-powered version with internal DSP, 24

DEFLECTOR LINE
The most important features of this range can be outlined as follows:
1) a higher rigidity/weight ratio;
2) outstanding quality of the speakers and the electronics used in the
active versions.
Among many reasons why, Deflector Line features can be distinguished from those of competring products within the same sector
by the following characteristics:
• a cabinet made out of multuply Canadian birchwood with a thickness of 15 mm,
• reinforced internal angles for the suspension system in 420ML alloy iron,
• pratical aluminium flying tracks on the upper and lower walls of the
speakers,
• ergonomic handles with a double grip,
• sound-transparent grid - it does not obstruct the holes in the internal
sponge - , secured to the chassis with retractable screws, that are
embedded in specific holes in the wood,
• a neodymium woofer with a 4” coil supported by fibreglass,
• an innovative AWSH™ (Acoustic Wave Shaped Horn),
• proprietary technology curved deflector.
3. CONTROLLED AIR FLOW TECHNOLOGY
All of the Deflector line upper modules (with the exception of the
“small” 2-way model XTD88) have been designed and produced
with an extremely innovative bass reflex. The classic tubular shape
has been superseded by a “sail-side” duct placed in the immediate
vicinity of the woofer, between it and the base of the cabinet, following its circular profile. This solution was reached during the design
stage, relying on particular fluido-dynamic simulations, with the aim
of minimizing air turbulence inside the cabinet and the duct itself.
As well as being considered for different types of clusters based on
the horn’s dispersion angles, the mixed inclination of the outer walls
has also been optimized, taking into account the afore-mentioned
simulations, with a view to harmonizing the sound pressure inside the
cabinet and reducing resonance to the minimum.
While standing in front of a speaker and sectioning it lengthwise with
a perpendicular plane, it is easy to identify the profile of the deflec-
tor, which has a convex-concave shape (according to the convection that mentions the intrados first, which is the lower surface, and
then the extrados, the upper surface) and also a camber – this is
defined as the distance between the wing chord and the mean line:
concerning the classic “roundedness” of the wing surface – this is
extremely reduced so as not to unnecessarily obstruct the air flow
controlled by the deflector. As above-mentioned, the X-Treme design team carried out special fluid dynamic simulations and created
numerous prototypes in laboratory; all of this had the aim of reaching
the long-awaited air flow control generated inside the cabinet and
the duct. From irregular and vortical, due to the “whirlpool” of the
bass reflex, this flow is transformed – in a non-viscous environment
and at sufficient distance from the walls – into a regular and laminar
one, thanks also to the intervention of a specific back frame, which
has a 5 cm thickness and to the 5 degrees tilt of the plane where
the loudspeaker is mounted. As well as being conceived for its different types of clusters in accordance with the horn’s dispersion angles, this mixed tilting of the outer walls was designed to eliminate
typical turbulences, which particularly appear on the tuning tube:
this means that the waves reflecting on the woofer are minimized
and, owing to the precise cone-duct alignment (the tolerance field is
measured in mm), the resonance and phase cancellation in the input
and output points disappear completely, with resulting harmony and
sound pressure optimization inside the cabinet.

4. ACOUSTIC WAVE SHAPED HORN
The aluminium AWSHTM (Acoustic Wave Shaped Horn) was designed and manufactured using CAE tools (Computer Aided Engi-
neering) to guarantee the sound centre and woofer alignment, while
keeping the planes containing the openings of the woofer cone and
the horn itself perfectly fitted together. The production process is carried out via die casting, by pouring the melted alloy into a permanent
metallic mould or die, specifically designed for this original product
on the specifications of the X-Treme engineers. The pressured manufacturing process allows the mould cavity to be filled very quickly
and the probable injection due to the reduction caused by solidification to be compensated. This produces the following effects: perfect and total cavity filling and a fine crystalline structure of the part,
free of imperfections. In the XTD88 and XTD1015 models, thanks
to a special AWSHTM horn being fitted in the opposite concave of
the speaker, it is possible to rotate the whole medium-high section
(horn+driver+panel) by 90°, therefore making it possible to maintain
the same coverage at high frequencies, both when the speaker is in
position, standard, vertical and when it is mounted horizontally. By
simply unscrewing the 8 screws in the external squared flange, it can
be rotated without damaging the connection cables or compromising the other internal elements.

5. SUBWOOFERS
The new subwoofer models XTDS15 and XTDS18 with a pass-band
configuration have been designed both physically and acoustically to
reach their maximum efficiency – thus the developed energy peak –
around 90 Hz: for this reason, these subwoofers are very compact
and “fast” and are designed to achive a higher output/dimension ratio.
The crossed internal reinforcement cages make the 15”-thick multi-ply
Canadian birchwood cabinet more resistant to the most critical and
enduring strains. Each model can be easily stacked both with other
unit of the same model, to create vertical subwoofer clusters, and
with the associated satellite: the XTD12 model is coupled with the 15”
subwoofer and the XTD15 and XTD1015 modules with the 18” one.
Fig. 5 XTD12 and XTD12/A models
The XTD15 model, like the amplified version XTD15/A, has a 600
W (AES) 15” woofer, a higher efficiency than the 12” XTD12, with a
Neodymium magnet and a 110 W driver with a Polyimide-titanium
membrane, a 3” coil, 1.4” throat diameter, and an in-built 1.4” AWSHTM aluminium horn. The horn dispersion angle is on average 90°
horizontal by 50° vertical. The speaker can produce a maximum SPL
peak of 134 dB.
