Designed for incredible sonic clarity and true full-range performance, the DV12-MKII is simply the best single 12” top on the market.
New features:
• Specially-developed high-performance woofer features increased excursion and power handling capabilities with reduced distortion.
• Upgraded compression driver from a 2.5” to 3” diaphragm, featuring smoother frequency response and increased sensitivity.
• Updated cabinet tuning takes advantage of improved low-frequency performance of new woofer.
• Multiple handles have been added, making set-up even easier.
The result is even higher output, resolution, depth and detail than the original. With the MKII, the DV12 again sets the standard for the
full-range compact main loudspeaker.
The DV12-MKII uses a line-array derived 1.4” throat isophasic wave guide instead of a conventional horn. The result is a combination
of very wide and consistent horizontal coverage (120°) with a tight vertical pattern (20°) that extends high frequency projection farther
than a conventional horn.
The lower frequencies are produced by a 12” woofer that features an ultra-light carbon-ber impregnated cone for outstanding
resolution, a cast aluminum basket for rigidity and reliability, a Neodymium magnet for light weight and high eciency, a 4” voice coil
for high power handling and a symmetrical, long-excursion suspension for accurate and extended bass response.
The amplier can deliver output peaks of 150V, to provide amazing dynamic resolution and impact. It also has a 10,000:1 damping
factor, which provides extremely tight control over the cone. The fully integrated and comprehensive digital processing ensures
smooth response and reliable operation thanks to meticulous lter alignments and dual stage limiters that protect the drivers from
excessive peaks, and also from thermal overload, by monitoring real power output over time. The amplier features a large heat sink
and 2 temperature-controlled fans to ensure consistent operation under even the most extreme conditions.
The DV12-MKII is the ultimate in plug and play, with universal voltage compatibility and no need for any outboard gear other than
a sound source. The processing features presets that allow it to run in several congurations. The rst is full-range mode, with response
down to 40Hz (-3dB). The other presets allow the DV12-MKII to be integrated with various types and sizes of subwoofers. Each preset
has a specic high-pass lter frequency, input sensitivity, high and low frequency limiter setting and subwoofer alignment processing.
The DV12-MKII can be combined with any BASSBOSS subwoofer because all the presets are programmed to align with all the
subs. Each preset oers dierent advantages that suit certain applications and preferences. No matter which preset you choose, your
BASSBOSS subs and DV12-MKII tops will always play in harmony.
The cabinet is assembled in the USA from premium selected 15mm Finland Birch. The design incorporates a 4-degree down-angle
that ensures even distribution of high-frequency energy from front-to-back of a venue when the DV12-MKII is placed at the appropriate
height on a tripod or support pole. Additional features include a 38mm (1-3/8”) cast metal pole socket, eight y points and six handles.
The amplier is recessed from the back of the cabinet to protect it in transit. A perforated steel grill protects the woofer, and it’s
progressive perforation pattern serves to broaden midrange dispersion. The high-frequency lens and port are left clear of the grill to
minimize reections and air ow noise that could compromise sound quality.
Should you ever need more sound than can be produced by one DV12-MKII per side, its invertible array feature allows perfect
summing of two speakers, which provides a big increase in output and projection without compromising the crystal clarity.
To further utilize the advantages of the line-array waveguides, the DV12-MKIIs are designed to stack with the HF lenses vertically
aligned. This allows the high-frequency sections of two boxes to sum perfectly as they would in a line-array while the low-frequency
sections sum in a column for improved low-frequency directivity and greatly increased output.
There is nally a speaker that allows two completely functional stereo systems to be combined into one without having to
compromise, either when they are together, or when they are separated.

Safety Information:
Important information regarding safety and the use of your loudspeakers:
Never stand in the immediate vicinity of loudspeakers driven at a high level. Professional loudspeaker systems are capable
of causing a sound pressure level detrimental to human health. Seemingly non-critical sound levels (from approx. 95 dB SPL)
can cause hearing damage if people are exposed to it over a long period. To prevent potentially dangerous exposure to high
levels of acoustic pressure, anyone who is exposed to these levels should use adequate protection devices.
When a transducer capable of producing high sound levels is being used, it is therefore necessary to wear ear plugs or
protective earphones.
See the manual technical specications to know the maximum sound pressure level.
• In order to prevent accidents when setting up the loudspeakers or loudspeaker stands, make sure they are standing on a
rm surface.
• Ensure that all additional hardware, xings and fasteners used for installation or mobile deployment are of an appropriate
size and load safety factor.
• Pay attention to the manufacturers’ instructions and to the relevant safety guidelines. Regularly check the loudspeaker
housings and accessories for visible signs of wear and tear, and replace them when necessary.
• Regularly check all load bearing bolts in the mounting devices.
The DV12-MKIIs can be arrayed in pairs, with the second cabinet inverted above the rst. Any preset can be chosen provided
both cabinets are set to the same preset and the gains are matched. Optional hardware is required to attach the two boxes
together. The hardware allows for adjustment of the total vertical coverage of the array. The DV12-MKII is also equipped
with a power pass-through facility that allows two boxes to be connected on a single power source. An optional PowerCON
jumper cable is available for this purpose. Using the signal and power pass-through connectors allows the minimum number
of cables to be run to the array. NOTE: Arrayed pairs must be set to the same preset number and level to achieve phase-
coherent summing.
Setup Addendum: When connecting multiple BASSBOSS loudspeakers in a system, signal can be passed through from one
powered loudspeaker to another using balanced, shielded XLR cables. No processing is applied to the signal as it passes
through from the input to the output connectors in each loudspeaker. Signal can be routed in
any sequence because each loudspeaker receives a full-range signal and applies the necessary processing in order to
operate as part of the overall system. It is recommended to run signal to the nearest box rst and patch to the next nearest
box in sequence.

To prevent the occurrence of noise on signal cables, use shielded cables only. Avoid routing signal cables close to equipment
that produces high-intensity electromagnetic elds such as transformers, power cables and loudspeaker wires. Do not coil
excess power cable. Do not coil or wrap power cables and signal cables together.
