Frequently Asked Questions
JBL Control 60 Series Pendant Loudspeakers
Control 60 Series Pendant Speakers
1. Why pendant loudspeakers?****
– 1. Easy to Install — JBL Control 60 Series pendant speakers are extremely
easy to install.
They suspend via an included 15-foot long cable using a snap hook and included
adjustable-height slide clamp.
– 2. Open Structure (ie, Open Architecture) Ceilings — They are an ideal
solution for open architecture ceilings where you don’t have a solid ceiling
surface for installing a ceiling speaker, or where the ceiling is not right
for a surface-mount speaker, or where you want to space the speaker down from
the open-ceiling surface and/or structural beams. 3. 3.
– 3. Closer to the Listeners — Suspending the speaker positions the sound
closer to the listeners for better direct sound quality (for better
intelligibility and music quality).
– 4. Below Obstructions — In some venues, it is important to get the speaker
down so that the sound doesn’t get blocked by decorative architectural
features or functional obstructions such as lighting or HVAC that may be
located below the ceiling.
– 5. Appearance — Suspended speakers provide a look that is becoming popular,
especially in open ceiling environments.
– 6. Height Options – The included suspension system allows the speakers to be
set at any height. This provides additional flexibility in the system design.
For example, in venues with a minimal budget for loudspeakers, raising the
speakers covers the area with fewer units, which may be acceptable as long as
the reverberation of speakers at that height is not a problem in that space.
Or, you can set them lower to get them closer to the listeners (see below for
more information about the advantages of this).
– 7. Reverberant Spaces & Difficult Acoustics — In highly reverberant spaces
such as transit centers, hotel lobbies, and other locations with hard,
reflective surfaces, a narrow coverage speaker such as the Control 67HC/T
reduces the sound splatter onto the walls and focuses the sound more directly
onto the listening plane, reducing the unwanted excitation of the reverberant
field. This increases the direct-to-reverberant ratio of the sound, which
improves the intelligibility of speech and clarity of music. Another solution
to difficult acoustics is to get the speakers closer to the listeners
(“reducing the D1”, as stated in engineering terms). Pendant speakers allow
positioning the speakers at a lower height even if there is no structural
support element at that height. Getting speakers closer to listeners is yet
another way to increase the direct-to reverberant ratio, improving
intelligibility and clarity.
– 8. High-Ceilings — Also related to the narrow coverage of the Control
67HC/T, in applications where the speakers are high above the listening plane
such as in convention centers, transit spaces and other high-ceiling venues,
narrow coverage speakers minimize the time-smear of the sound to the
listeners. For best intelligibility and clarity, each listener should
predominantly hear the sound from the speaker that is directly above them and
not hear as much of other nearby or far-off speakers where the sound would be
traveling a farther distance to get to that listener such that it would be out
of time sync with the direct immediate sound. Reducing the sound that gets to
the listener from those distant speakers increases speech intelligibility and
improves musical clarity. All of these are reasons to consider pendant
speakers in your projects.
2. What is the difference between the various Control 60 models?
In what applications would I use which Control 60 Series model?****
– Here are descriptions of the models and general starting-point guidelines as
to when each might be used: Control 62P is an ultra-compact mid-high frequency
satellite speaker which can be used by itself for speech or for mid-high
frequency music applications. The Control 62P is also designed to be an
excellent satellite speaker in a subwoofer-satellite system for full bandwidth
sound quality. For that purpose, two or four Control 62P speakers can be
driven from the “satellite outputs” of the Control 50S/T on-wall subwoofer or
Control 40CS/T in-ceiling subwoofer. (See more details below). Control 62P can
be intermixed with Control 42C in-ceiling speakers and Control 52 on-wall
speakers for applications that might require multiple form-factors of speakers
in the same location and where you want all the speakers to perform similarly.
This model is ideal when you need the speaker to be as small and visually
unobtrusive as possible. Control 64P/T is a compact, cost-effective full-range
model with 1 x 4-inch driver for 50 Watt continuous pink noise power (100W
program, 200W peak) and 65 – 15 kHz frequency response. Control 65P/T is a
compact full-range 2-way model, and it holds its own versus larger competitive
pendant speakers on output level and bass capability. Control 65P/T is good
for both speech and high-quality music systems. The RBI waveguide (see below)
provides excellent pattern control for consistent coverage of the listening
space. This model is excellent for applications where wide bandwidth and
constant-directivity coverage control is needed and where its output level and
frequency response are appropriate for the listening space. It provides wide-
bandwidth and high-fidelity sound quality. Control 67P/T has larger diameter
drivers and a larger enclosure than Control 65P/T, giving it greater sound
level capability, higher sensitivity, and extra bass output. It also has a
larger RBI waveguide (see below) for extra pattern control. It is ideal for
applications where you want maximum output, or for venues where you need
extremely uniform coverage.
– Control 67HC/T is a unique model in the market at anywhere near its
price point. It is a narrow-coverage pendant loudspeaker.
– For High Ceilings — This model is sometimes called a “high ceiling” speaker
because narrow coverage is beneficial when a speaker is mounted high in the
room. The narrow coverage concentrates the sound so that it can project with
clarity all the way to the floor area.
Narrow coverage is also beneficial for achieving clear intelligibility of
speech and clarity of music in high-ceiling applications by reducing the time-
smearing of sound that listeners hear. In a system with narrow-coverage
speakers, listeners located below one speaker hear more of the speaker that is
directly above them and less of the other nearby speakers. The sound from
these other speakers would otherwise hit their ear in different time syncs,
and hearing the same sound multiple times at different time syncs tends to
sound muddy, unclear and unintelligible.
– These are reasons why the narrow-coverage characteristic of Control 67HC/T
provides improved sound quality in applications when the speaker is located up
high in the room.
– For Reverberant Spaces — Narrow coverage speakers are very useful for spaces
that have a lot of reverberation, such as large rooms with solid reflective
surfaces. Not only do narrow coverage speakers direct more of the sound to the
listeners, they also help to keep sound off the walls, which helps to control
the reverberant field within the room.
– Control 68HP is the highest power, highest SPL model in the line. The 8-inch
woofer is the largest size and high frequencies are produced by a compression
driver for high
output and efficiency. The 250 Watts of continuous average power handling
(500W Continuous Program, 1000W peak) produces a very high SPL of 114 dB
continuous (120 dB peak).
3. How many speakers should I use to cover a space?****
– Similar to when using ceiling speakers, how many pendant speakers to use
depends on the coverage angle of the particular pendant speaker, the height of
the speaker, and the
desired coverage density (which affects the amount of sound level variation
you get from place to place within the listening space, as well as affecting
the sense of richness of the sound). It is easy to design Control 60 Series
models into projects using JBL’s DSD Distributed System Design software
(available at no charge from the JBL Professional website:
www.JBLPro.com, in Downloads, Software). Simply enter
the height that the bottom (grille) of the loudspeaker will be above the floor
as the “ceiling height”. DSD tells you how far to space them apart, how many
speakers to use (for a rectangular space), approximately where to place them,
how loud the system can get (with 10 dB of headroom), how much variation of
sound level you’ll get within the space from the quietest spot to the loudest
spot, and the recommended amplifier power.
Once you have these parameters, it is easy to set the exact speaker locations
in your architectural drawings of the space.
Design data from JBL’s
DSD Distributed Speaker Design Software
– EASE files are posted on the www.JBLPro.com website
(on eac h Control 60 Series model page) for doing complete floor-plan coverage
modeling. In addition, 2D and 3D DXF case drawings are available for showing
how the speaker will look in the space.
4. How well do Control 60 speakers cover the listening space? What does the RBI Radiation Boundary Integrator® do?****
– The JBL Control 60 Series speakers cover the listening space more evenly
than any pendant loudspeaker on the market today. JBL’s proprietary conical
RBI Radiation
Boundary Integrator
was adapted from the JBL’s groundbreaking line array loudspeakers. This unique
patented innovation® combines a large-diameter waveguide for high-frequencies
with low-frequency apertures. The two work in tandem to provide an unmatched
level of pattern control along with seamless coverage in the crossover region.
The result is extremely consistent pattern control and even coverage of the
listening space such that all listeners hear a consistently uniform flat
frequency response.
– In addition, the RBI results in the mid and high frequencies tapering down
evenly at the edges of the speaker’s coverage pattern, just as the next
speaker is starting to evenly fill
in that space, resulting in better sound at the overlap areas between the
coverage of multiple speakers.
– This level of consistent coverage from the Control 60 Series models means
that EQ’ing the sound for one spot (if necessary to account for the acoustics
characteristics of the
room) achieves the same great sound at all locations within the room.
By comparison, with competitive speakers having inconsistent coverage every
frequency tends to die off at a different angle than other frequencies.
Therefore, the sound in every spot sounds different. The edges of those
speakers’ coverage patterns tend to be especially inconsistent, containing
some frequencies (the wide-coverage frequencies) and not others (the
frequencies that beam), resulting in adjacent speakers not combining well at
the overlap between speakers. With such inconsistent speakers, EQ’ing the
sound for improved sound at one location often results in the sound becoming
worse at other locations.
In addition to the sound quality benefits of RBI, the uniform coverage of the
Control 60 models often allows the use of fewer speakers in a system — fewer
speakers can cover a
larger area while at the same time eliminating drop-out spots. That can save
money in a project, both for the cost of the loudspeakers themselves and for
the cost of installing and powering the loudspeakers.
– Note: RBI Radiation Boundary Integrator® is incorporated into all
Control 60 Series models except for the ultra-compact Control 62P.
5. Can I Use Control 60 Series Loudspeakers Outdoors?****
– In many cases, Control 60 Series models can be used outdoors, such as the
patio areas outside of restaurants, however, the installer needs to use
standard cable clamps for the suspension cable – see below:
– 1. Rubber Covers – Two rubber covers for the two euro-block-type connectors
are included with each speaker. These cover the connections on the top
panel.
– 2. MTC-PC Terminal Covers – Optional terminal covers are available as
accessories. The MTC-PC60 panel cover (for models Control 65P/T, 67P/T,
67HC/T, and 8HP) and MTC-PC62 panel cover (for Control 62P) can be purchased
to cover and seal the terminal compartment at the top of the loudspeaker.
Note: These covers are priced individually and sold in pairs.
– 3. Construction – The cabinet material is high-impact polystyrene, which is
the same material as most of our outdoor capable surface-mount (on-wall)
Control Contractor® speakers. All woofer cones are polypropylene coated and
the surrounds are pure butyl rubber. All these materials are suitable for
outdoor applications. The grille is zinc-plated painted steel. The zinc-
plating protects the grille from corrosion, but it can corrode given enough
time outdoors and enough exposure and the corrosion can be accelerated in
salt-air environments. The grilles have foam backings which can help to break
up driving rain. The suspension cable is high-tensile galvanized-steel wire
rope, but the Gripplebrand cable fasteners are only for dry locations, so you
should use other standard cable clamps, such as Crosby–type clamps or Nico-
press fittings.
– 4. Wind Outdoors – To prevent the enclosure from swaying in the wind, the
speaker should be stabilized via a 3-point suspension utilizing three trim
cables to the three clip points on the speaker’s top bracket.
6. Are the Control 60 Series speakers UL certified?****
– Yes, all the Control 60 models are UL1480A (UEAY) certified. The 70V/100V transformers are UL1876 registered. The Gripple®-brand cable fasteners have numerous certifications which are listed on the installation instruction sheet.
7. Can I Use Control 60 Series Loudspeakers in places that require enclosed terminal compartments for code compliance?****
– Yes, the optional MTC-PC60 and MTC-PC62 panel covers enclose the terminal compartments.
8. How do I use the Control 62P with a subwoofer as a full-range system?****
– The ultra-compact Control 62P can be used by itself for speech or for mid-
high frequency music applications. For full-range wide bandwidth performance,
the Control 62P needs to be coupled with a subwoofer. Up to four Control,
62P’s can be driven from a wall-mounted Control 50S/T or in-ceiling 40CS/T
subwoofer to form a full-range passively crossed-over subwoofer/satellite
system. Or, the satellite speakers and subwoofer can be driven by separate
amplifiers and actively crossed over elsewhere in your sound system
electronics.
– Using the Subwoofer’s Built-In Crossover — The full-range signal from the
power amplifier is fed to the subwoofer and either two or four Control 62P
speakers are connected to the “Satellite Out” terminals of the subwoofer. A
full crossover network is built into the subwoofer. Low frequencies are
produced by the subwoofer. Mid-range and high frequencies are directed to the
satellite speakers.
– Note: These subwoofers require either two or four satellite speakers to
be connected to them. They do not work with either one or three satellite
speakers. Safety — If the Control 50S/T subwoofer is utilized with its
included wall bracket, then the subwoofer must be installed on a wall, not on
the ceiling. However, if you remove the included wall bracket, the four
suspension points on the back panel can be utilized with Unistrut or other
hardware for suspending the subwoofer or attaching in other orientations.
– Note: Ensuring safe installation is the responsibility of the system
designer and installer. Always utilize the secondary M6 safety attachment
point per the instructions provided with the subwoofer. Using an External
Electronic Crossover — A crossover frequency no lower than 140 Hz is
recommended.
8a) Can I intermix sub-sat systems with full-range 70V (or 100V) speakers?****
– Yes, both the Control 50S/T surface-mount subwoofer and the Control 40CS/T in-ceiling subwoofer can be operated in 70V/100V mode or as a low-impedance (8 ohms) speaker. They have multiple 70V/100V taps just like a full-range 70V/100V speaker. Therefore, they can be driven directly from a 70V/100V distributed speaker line that could indeed have full-range speakers also attached to it. You can have full-range speakers and the subwoofer-satellite system both driven from the same 70V/100V distributed speaker line. Regardless whether the subwoofer’s tap selector is set at one of the 70V/100 taps or at the direct low-impedance (8 ohm) setting, the satellite speakers should be low-impedance (in this case, 16 ohm) speakers (ie, not 70V/100V satellite speakers).
8b) Can I intermix Control 62P speakers with in-ceiling and/or surface- mount speakers in the same subwoofer-satellite system?****
– Yes, the Control 62P is essentially the same speaker as the Control 52
surface-mount (on-wall) speaker and the Control 42C in-ceiling speaker. They
all have a similar sound
character, similar frequency response, similar sensitivity, similar
directivity, and similar impedance.
– Therefore, you can inter-mix Control 62P, Control 52 and Control 42C
speakers, even within the same subwoofer-satellite system. This is useful if
you have a venue that
requires different form factors of satellite speakers, such as a low-ceiling
section and an open-architecture ceiling section.
9. In the past, pendant speakers have tended to look a bit … strange … and didn’t fit in visually with my applications. What is different with Control 60 Series?****
– JBL’s Control 60 Series pendant speakers were specifically designed to provide an elegant look that fits into a wide variety of decors. They are stylish yet understated. They do not draw too much visual attention to themselves to take away from the architecture, yet they are graceful. They were designed to enhance the decor of most venues.
