Introduction
8” Compact bass cabinet
NOBA8 is characterized by an innovative & unique design. With its curved shape, made of
4 mm thick aircraft graded aluminum and its extremely powerful 8” woofer of 200 Watts,
the NOBA8 is able to deliver an unheard low frequency response for its small woofer size.
The perfect acoustic experience is guaranteed when the entire audio frequency spectrum is
equally distributed. The slick look of the NOBA8 allows it to be placed against a wall, on the
ceiling or even underneath furniture, yet due to the unique composition of its parts, NOBA8
ensures a much better spreading of sound waves than other similar cabinets.
The connection is made using a terminal block connection located at the inner side of the
supporting structure. This allows close placement to any wall or corner.
The NOBA bass cabinets are available in black (/B) or white (/W).

Overview
The aluminum enclosure features a grill on both sides, whereof one side includes the bass
port. To allow optimal air-circulation through the bass port, make sure this side remains
uncovered when installed.
Placement
The low frequencies produced by a bass cabinet are non-directional, and therefore the
placement of the subwoofer in the listening area is not critical. However, few simple rules
concerning its positioning can significantly influence the result.
Low frequency sound reproduction is coupled with boundaries, which results in a longer
carriage and higher sound pressure level. The NOBA8 is designed in such way to allow easy
placement and mounting to any wall or ceiling through the available mounting brackets.
When having multiple bass cabinets in your setup, side-by-side placement will result in
an acoustic coupling between them which provides an increased SPL and punch. However
some other applications will require a wider dispersion of bass, depending of the room size,
layout and acoustics.
The ideal positioning of bass cabinets is highly depending of the typical application, and there
is no such perfect way which is always right. Making some experiment-wise tests about
placement and coupling of bass cabinets can lead to improved results.

Connection
Connection panel overview
Connection panel description
Terminal block input connection:
The connection of the NOBA8 is made using a 2-pin terminal block connection whereto
the wires coming from the amplifier shall be connected. There isn’t any internal low-pass
network provided, which means the applied signal should be filtered / processed using an
external crossover or amplifier featuring active filtering or DSP processing.
Mind the polarity markings when wiring the loudspeaker cables.

Mounting
The NOBA8 comes standard delivered with a mounting bracket for on-wall installation.
The installation of this bracket shall be done according to a simple 5-step procedure as
described below:
Step 1: Remove the rubber feet
The cabinet comes delivered with 4 pcs of rubber feet assembled supporting the cabinet
for floorstanding use. When installing the cabinet to the wall, two pcs of these rubber feet
must be removed for assembly of the supporting bar. Note that the cabinet can be mounted
in two directions. Depending of the required direction (position of the connections, amplifier
and bass port) both feet on the upper side needs to be removed. Keep the removed screws
for the next step.
Step 2: Assembling the cabinet supporting bar
Once both rubber feet are removed, the supporting bar for hooking the cabinet to the wall
plate needs to be assembled. Place the supporting bar on the position where both rubber
feet were located and fix it with the screws removed in step 1. Mind the mounting direction
when installing.

Step 3: Mounting the wall plate
Mount the wall plate to the installation location of the NOBA8. The wall plate has to be fixed
using four screws. The exact screw positioning is shown in the drawing below. The used
fasteners should be chosen depending on the mounting surface (brick, concrete, wood,
gypsum, ... ). Make sure the mounting surface can structurally support the weight of the
speaker.

Step 4: Connect the wiring
Once the wall plate is mounted, the wiring shall be connected before hooking the cabinet to
the wall plate. For more information how the connections should be made, check chapter 2
and chapter 3 of this instruction manual. When connecting, make sure all wiring is guided and
fixed properly so the loose wiring won’t touch any moving parts such as the speaker cone.
Step 5: Hook the cabinet to the wall plate:
The last step is hooking the cabinet to the wall plate. This is done by sliding the cabinet
support bar over the wall plate followed by a downwards movement of the loudpeaker, as
indicated in the drawing below.
