HSU CCB-8 User manual

Constant Directivity Coaxial
The CCB-8 utilizes the woofer cone and pole piece as the constant directivity horn for the tweeter which is
mounted behind the woofer magnet. This gives an extremely high efficiency tweeter, over 100 dB sensitivity,
with good directivity and excellent micro and macro dynamics. Unlike the HB-1, the CCB-8 is a point source,
yielding imaging and balanced tonality that is second to none no matter where you sit.
The CCB-8 uses a 8-inch cast frame woofer with a 2˝ edge wound copper clad aluminum voice coil for the
highest possible efficiency and speed. This is coupled to an acoustically inert polypropylene cone and a well
damped cloth surround. The wide dynamic range capability of this woofer matches the tweeter perfectly.
The complete absence of lobbing in the CCB-8 thanks to the coaxial design means it’s perfect as a center channel
speaker. Just lay it on its side.

A. Unpacking
Open the top of the carton and lift up the top foam tray. Carefully lift up
the speaker(s). Open the foam bag(s).
Save the carton, foam trays and foam bags – they are the best protection for
your speakers should you need to move them or send them back for service.
B. P acement for Two Channe Stereo
Note: For optimum bass performance, use a system with bass
management and crossover the CCB-8s to a subwoofer at 80 H .
Positioning Your Subwoofer
See your subwoofer’s owner’s manual.
Positioning the CCB-8s
For smoothest response we recommend placing the CCB-8 such that the
coaxial driver’s distance to the closest surfaces are in 1:2:4 ratio (side wall
Y, floor Z, and back wall X - see Fig. 1). On the recommended 36˝ stand,
that would be 22˝ from the side wall and about 7 ft from the back wall.
That way, the dip caused by the side wall bounce is canceled by the floor
bounce and the dip caused by the floor bounce will be canceled by the
bounce off the back wall. The dip caused by the back wall bounce will be
below the recommended crossover frequency for the CCB-8.
Note that the above recommendation will result in the smoothest response,
but is not mandatory. It’s fine if the WAF factor or other practical reasons
make that impossible. Our speakers are no more sensitive to positioning
than any other speakers. In fact, due to it’s better controlled directivity, it’s
less sensitive than most.
Toe in the CCB-8s
The CCB-8s are designed to be toed in so you sit 15 degrees off axis.
i.e., cross the axis of the coaxial drivers about a foot or two in front
of you. This gives the most stable imaging and the widest sweet spot.
The frequency response is also designed to be smoothest at 15 degrees
off axis.
C. Wiring
The CCB-8s 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 CCB-8 (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 CCB-8s as needed – seven for a 7.1 system,
five for a 5.1 system, etc. Connect one CCB-8 to each speaker output.
ake sure you observe the polarity.
ost 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 (–)
negative. 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).
The magnetically attached grille can be rotated as needed so the Hsu
logo is upright whether the speaker is used on it's side or upright.
You can also rotate the terminal cup as desired.

E. Troub eshooting 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 associ-
ated 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
speaker. If it does, the problem likely originates in some other com-
ponent 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.
