Introduction
Thank you and congratulations on your purchase of the HAFLER VRM series of satellites. The VRM series are two-
way passive speakers primarily used for front stereo, center channel, or rear surround channel applications. They
are designed for use with high quality Hafler power amplifiers.
The VRM5 and VRM6 are optimized for front stereo and rear surround applications. The VRM5 uses a 1”tweeter
with a 5”driver and the VRM6 uses a 1”tweeter with a 6”driver. The VRM25 and VRM26 are optimized for front
stereo towers and center channel applications. The VRM25 uses a single 1”with dual 5”drivers and the VRM26
uses a single 1”with dual 6”drivers.
Although the VRM satellites are passive models they have technical circuitry and features that ensure excellent
sound quality in every application. Crossover design is a 24dB/octave Linkwitz Riley that filters high frequencies to
the tweeter and low frequencies to the woofer. The 6”driver utilizes a Zobel network to extend the high frequency
range and a parallel conjugate network to maintain Minimal Impedance Deviation (MID). The tweeter circuit also
incorporates optical protection for “overload”protection and a 0dB/-3dB tweeter pad to match the tweeter level to
the midrange for the best balance in sound.
Combine the Ebony Ash Vinyl finish with the technical features and you’ll see the HAFLER VRM series provide the
home theater enthusiast with loud levels, excellent sonic quality, and wide dynamic range, with excellent power
handling and a stylish look.

Home Theater Installations
Home Theater installations are typically medium sized
living rooms or game rooms that have large flat, uncov-
ered walls. Acoustics in this type of installation can
have a big effect on the SPL (Sound Pressure Level) and
f3 (low frequency cut-off) of the subwoofer because the
walls are very reflective. The only elements in these
installations that acoustically “absorb”sounds are furni-
ture and carpet. Dramatic “Boundary Loading”can be
achieved by locating the subwoofer under a table, next
to a wall or in a corner (FIG. 4), thus increasing SPL
and lowering the f3 of the subwoofer system. Locating
the subwoofer in the middle of the room or in a large
open area where there are few reflective surfaces will
cause a decrease in SPL and an increase in f3.
Experiment with different locations in the room to
determine which type of bass response works best in
your home theater.

Location
The size of the room used for your Home Theater can have a significant effect on the bass response of your system. Since
many movies exaggerate explosions, earthquakes, and other low frequency effects, a high demand on the subwoofer system
is required. Your Hafler subwoofer is specially designed for these high levels of excursion and linearity. In order to get the
most out of your subwoofer, Hafler has documented the differences between typical Studio and Home Theater installations.
Typical Studio Installations
In studio installations, damping material is usually used on the walls and ceilings make the room “acoustically dead." In
this type of anechoic environment, the subwoofer will tend to experience minimal “Boundary Loading”effects. Firing the
subwoofer downward (FIG. 1) or directly facing forward (FIG. 2) and keeping the cabinet at least 5”(12.7 cm) away from
any wall will provide best results.
