The L-ACOUSTICS® dV-SUB is the
companion subwoofer for dV-DOSCTM
and features three 15-inch transducers
loaded in a dual-chamber vented
bandpass configuration. With power
handling capacity of 1200 Wrms and
response to 35 Hz, dV-SUB is ideal
for applications requiring maximum
low end impact from an extremely
compact enclosure.
Important design criteria in the
development of dV-SUB were maximum SPL output combined with low
frequency extension from an enclosure as compact as possible. Dualchamber vented bandpass loading
provided the answer. High power
handling components also contribute to the SPL performance and since
15'' transducers are operated in
parallel this presents an optimum
2.7 ohm load to the power amplifier.
Rigging flexibility was another key
consideration and dV-SUB's integral
rigging system allows for the installation of a single flown column of
dV-DOSC and dV-SUB enclosures
(with dV-SUB flown at the top of the
array and dV-DOSC underneath).
Although deeper than dV-DOSC,
dV-SUB has the same width and in
keeping with the recommended
ratio of 3 dV-DOSC : 1 dV-SUB,
enclosure height is equivalent to
approximately 3 dV-DOSC. This
allows for the creation of physically
compact arrays when dV-SUB is
flown on either side of dV-DOSC in
a coplanar symmetric arrangement.
Either single column or coplanar
symmetric flown configurations can
be used in FOH applications for
small, medium or large venues and
also in large-scale fixed installations
such as multiple distributed arrays
for stadium or arena sound reinforcement. For theatrical applications,
where visually unobtrusive sound
design is critical, dV-DOSC plus
dV-SUB is ideal for stereo infill
(floor), main left/right (balcony) or
center cluster use.
The 695 mm (27.4-in) cubic dimensions of dV-SUB are highly
convenient for ground-stacked
applications where dV-SUB serves
as a stacking platform for
dV-DOSC.This combination is also
ideal for stage monitoring applications such as sidefill or drum fill.
Presets for use of dV-SUB with the
floor monitor and ARCS are also
available, offering a wide variety of
enclosure combinations.

L-ACOUSTICS specifications are based on measurement procedures which produce unbiased results and allow for realistic performance prediction and simulation.
Some of these specifications will appear very conservative when compared with other manufacturer ’s specifications. All measurements are conducted under free

The loudspeaker system shall contain three fifteen inch loudspeaker
components, loaded in a dual-chamber vented bandpass enclosure
suitable for subwoofer applications. Power handling capacity shall be
1200 Wrms long term (4800 Wpeak) at a nominal impedance of
2.7 ohms. Usable frequency response shall be 40 to 200 Hz
(± 3 dB) with -10 dB response at 35 Hz referenced to the average
level of the usable response. The three fifteen-inch transducers
employed in the enclosure shall have a 3-inch (75 mm) diameter
edgewound copper ribbon voice coil, a weatherproof cone body,
diecast aluminum basket, massive vented magnet structure and high
thermal capacity.
The loudspeaker enclosure shall be constructed of 24 mm (0.94 in)
baltic birch and be internally braced with steel corner plates and joints
that are sealed, screwed and rabbeted in order to remain free of
vibration at extreme sound pressure levels. Dimensions shall be
