Features
High Definition
The HB-1 MK2 utilizes a controlled-directivity horn that gives excellent micro dynamics
and imaging under real world conditions that few other transducers can match without
the typical horn sound.
Wide Dynamic Range
The HB-1 MK2 is both efficient and high power handling. It provides effortless dynamics
to handle high-definition audio programs and home theater.
Works Perfectly with Subwoofers
The HB-1 MK2 was designed specifically to work best in systems using a subwoofer or
mid-bass module plus low-bass subwoofer.
High-Definition Audio Speakers by HSU Research.
Designed and engineered in the U.S.A.

A. UNPACKING
Carefully remove your new HSU speaker from its box, avoiding staples
which can cause damage to the cabinet. If you discover damage, contact
us and the shipper immediately.
Save your cartons – they are the best possible protection for your
speakers should you ever need to move them.
B. PLACEMENT
Note: For optimum bass performance, the addition
of a subwoofer,or a mid bass module plus a low
bass subwoofer is highly recommended.
Positioning Your Subwoofer
See the subwoofer owner’s manual.
Positioning Your Satellites
For best imaging, the HB-1 MK2 should be placed such that the tweeter
is at ear level when seated, woofer closer to the floor, aimed directly at the
primary listener. The distances to the three nearest solid surface should
be in the ratio 1:1.26:1.60. When you have the distance to the floor the
greatest, for a typical ear height of 40" (i.e., woofer 34" off the floor), this
translates into 21 and 27" from the two nearest walls (Figure 1).
If the HB-1 MK2 is used as a center channel, it’s best to use it in the
normal upright position just like the left and right speakers. You can
also lay it on its side at the expense of horizontal polar response.
Note that the HB-1 MK2 is NOT magnetically shielded and should not
be placed on top of a direct view TV. It is perfectly fine to place it on
top of a Rear Projection TV or near an LCD or plasma TV.
We have in-wall versions of the HB-1 MK2 if you prefer not to use
speaker stands.
C. WIRING
The HB-1 MK2s do not come with wires. We suggest getting 16 AWG for
runs under 10 feet, 14 AWG for runs of 10 - 25 feet, and 12 AWG for
runs of 26 - 50 feet.
Strip 1/2˝ of insulation from each end of the wire to expose the bare
metal. Insert this into the 5-way gold plated binding posts on the back
of the HB-1 MK2 (Figure 2). Alternatively, you can use banana plugs.
If you are connecting using bare wires, make sure the binding posts
are tight, and no stray wires strands are causing a short.
D. SETTING UP
Purchase as many HB-1 MK2s as needed – seven for a 7.1 system, five
for a 5.1 system, etc. Connect one HB-1 MK2 to each speaker output.
Make sure you observe the polarity.
Most speaker wire is polarity coded. This means that each conductor
is labeled either (+) positive or (-) negative. The (+) positive side
may be a different color or texture than the (-) negative side. On the
back of your amplifier, each channel is probably labeled (+) and (-
) as well as color coded red for (+) positive and black for (-) nega -
tive. HSU speaker terminals are color coded red for (+) positive and
black for (-) negative. Be sure to hook (+) to (+), (red to red), and
(-) to (-), (black to black).

E. TROUBLESHOOTING
AND SERVICE
We use components and designs of the highest caliber as a means of
ensuring a long and trouble free life for your speaker. However, no
amount of protection will prevent damage caused by defective associated
equipment or extreme abuse.
If you have a problem, first try to determine if it is indeed a speaker
problem. Determine whether the problem exists in more than one speak-
er. If it does, the problem likely originates in some other component in
the system. If the problem is in one speaker only, reverse your speaker
connections (left to right, right to left). If the problem moves to the other
channel, your problem is not in the speakers. Once you have determined
that you have a speaker problem, contact us at the location shown below
for service. Please describe the problem in detail. We will decide on the
most appropriate course of action.
