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.
