NHT model 2.5i Guia Do Utilizador
Placement
The Model 2.5i is a floorstanding tower speaker that requires no stands or mounting hardware other than the included SpikeKit. The
Model 2.5i is designed for indoor use only. As the Model 2.5i is not a magnetically shielded loudspeaker, do not place it closer than 18
inches from a television. Unshielded magnets placed in close proximity to a television screen can cause discoloration of the picture. If
you notice picture discoloration, move the speakers away from the TV until the problem disappears.

The most impressive performance benefit of Focused Image Geometry is spectacular imaging and an expansive soundstage. To
achieve this in your home, we recommend that the 2.5i’s are situated at least 12 inches from the rear wall (due to the rear vent) and at
least 30 inches from the side walls. For smoothest response, the distance from the side walls should be different than the distance from
the rear wall. The speakers should be arranged as symmetrically as possible, with their backs parallel to the rear wall and the drivers
facing the listening area without obstruction from furniture. Arrange the speakers so that the distance between the listener and the
center of the speaker plane is 1.5 times the distance between the speakers (fig.1). This configuration puts the listener in the center of
the stereo image.

Experimentation is the key to finding the best arrangement in your listening environment. Be patient, have fun, and remember that small
changes in speaker position can sometimes have a significant effect on the sound. For example, moving the speakers nearer to a room
boundary (walls, corners) will tend to increase their bass output, but may result in “boomy” or “muddy” sound. Conversely, placing the
speakers farther away from room boundaries will tend to decrease their bass output, but may result in greater articulation and better
imaging.

In addition, room furnishings play an important role in absorbing and reflecting soundwaves. Midrange and high frequencies in par-
ticular will be absorbed by soft furnishings such as sofas, carpets and curtains. A large number of these soft furnishings will dull the
sound, while a “live” room with few furnishings will brighten the sound. If you are willing to spend some time fine-tuning the performance
of your system, you will enjoy the benefits for years to come.

SpikeKit Installation
A SpikeKit is included with the Model 2.5i to provide optimum stability and to firmly couple the speakers to the floor for improved bass
performance. Each 2.5i loudspeaker is shipped with its own SpikeKit. Caution: the 2.5i is unstable without the SpikeKit (or at least
the stabilizer bars) installed.
performance. Each 2.5i loudspeaker is shipped with its own SpikeKit. Caution: the 2.5i is unstable without the SpikeKit (or at least
the stabilizer bars) installed.
To begin assembly, unpack the SpikeKit and inspect all the parts. The SpikeKit includes: (2) stabilizer bars, (4) metal cones, (4) Phillips
head machine screws and (4) rubber feet. We recommend installing the cones only after you have found the ideal location for the
speakers. Begin by installing the stabilizer bars. Carefully turn the speaker upside down or on its back, and attach the stabilizer bars
with the Phillips head machine screws, using a #3 Phillips screwdriver (fig. 2). Note: When installing the bars onto the bottom of the
speaker, use your fingers to start all the machine screws in their holes before tightening them down. This will prevent
crossthreading.

Before installing the cones, turn the speakers upright and position them. Once you have found the ideal location, carefully tilt the
speakers and screw in the cones. The speakers are awkward to move after the cones are installed. Caution: The cones are very
sharp. To avoid injury, use extreme care when handling and installing them. Adjust the spikes as needed to ensure that the 2.5i
is level and does not rock in any direction. If you have hardwood floors or floors with a scratchable surface, you may choose not to use
the cones because they will pierce the surface. Rubber feet are provided and can be used in place of the cones. Install the stabilizer
bars, peel off the adhesive backings from the rubber feet, and place them over the holes where the cones would screw in.
