Description

The JBL Harman 4367 boasts a sleek, durable design with a birch plywood cabinet and a leather-wrapped baffle. The speakers are engineered to deliver accurate sound reproduction with minimal distortion, making them ideal for critical listening environments. The dual compression drivers and horn-loaded woofers ensure clear highs and deep, resonant bass. This speaker system is built to last with high-quality components and meticulous craftsmanship.

INSTALLING THE SPEAKER'S FEET

Before using the speaker, install the supplied spiked inserts into the speaker's metal feet.

1. Turn the speaker upside down onto a thickly carpeted or well-padded surface.
2. Screw the spiked inserts into the feet.

IMPORTANT: To prevent damage (scratches, indentations, etc.) to wood or linoleum floors due to the weight of these speakers, always use the included coasters. Be especially sure to use the coasters on tile surfaces to prevent cracking the tile.

PLACEMENT

Before deciding where to place your speakers, note that the floor at your selected location must be capable of supporting a load of 54 kg (119 lb). Because the stainless-steel feet solidly couple the speaker to the floor, a 
flat, hard surface such as wood or linoleum is preferable. However, the coupling system, along with the speaker's substantial weight, should result in excellent performance on any surface, even carpeting.

To decide on a final location for your speakers, survey your room and think about placement using the illustration below as a guide.

For best results, place the speakers about two to three meters (about six to ten feet) apart. If you place the speakers farther apart, angle them toward the listening position. The speakers will produce the most accurate stereo soundstage when the angle between the listener and the speakers is between 40 and 60 degrees.

Position each speaker so that its tweeter is approximately at ear level. Generally, bass output will increase as the speaker is moved closer to a wall or corner. For best performance, we recommend that you place the speakers at least 50 cm (about 20 inches) away from the side walls.

NOTES ABOUT SPEAKER PLACEMENT:

• To prevent damage (scratches, indentations, etc.) to wood or linoleum floors due to the weight of these speakers, always use the included coasters. Be especially sure to use the coasters on tile surfaces to prevent cracking the tile.
• Avoid placing the speakers near power amplifiers, heat registers or other objects that generate large amounts of heat.
• Do not place the speakers in very humid or dusty places.
• Do not place the speakers in direct sunlight or in places where they will be exposed to other strong light.
• The 4367 is not video-shielded and may distort or discolor the picture if placed close to some types of TVs. If the speakers do distort or discolor your TV's picture, move the speakers away from the TV until the distortion or discoloration disappears.

CONNECTIONS

CAUTION: Make sure that all of the system's electrical components are turned OFF (and preferably unplugged from their AC outlets) before making any connections.

Speakers and amplifiers have corresponding positive and negative ("+" and "-") connection terminals. The 4367 has two sets of connection terminals; jumper wires connect the terminals to each other. The terminals are marked "+" and "-" Additionally, the "+" terminals have red rings, while the "-" terminals have black rings. See the illustration below.

1. We have designed the 4367 so that a positive voltage at the "+" (red) terminal will cause the speaker transducers to move outward (toward the room).
2. We recommend using a high-quality speaker wire with polarity coding. The side of the wire with a ridge or other coding is usually considered positive polarity("+").
3. To ensure proper polarity, connect the left- and right-channel "+" terminals on the back of the amplifier or receiver to their respective "+" (red) terminals on the speakers. Connect the "-" (black) terminals in a similar way. See the owner's manual of your receiver or amplifier to confirm its connection procedures.

BASIC SINGLE-WIRE CONNECTION

Connect the amplifier to each speaker as shown in the illustration below. You can use either set of terminals on the speaker. NOTE: Do not remove the jumper wires from between the two sets of terminals when connecting the speaker wires.

IMPORTANT: Do not reverse polarities (i.e.,"+" to"-" or"-" to"+") when making connections. Doing so will cause poor stereo imaging and diminished bass performance. The 4367's gold-plated speaker terminals can accept a variety of wire-connector types: bare wire, spade connectors, pin connectors and banana connectors.

Using Bare Wire or Pin Connectors

IMPORTANT: Make sure the (+) and (-) wires or pins do not touch each other or the other terminal. Touching wires can cause a short circuit that can damage your receiver or amplifier.

Using Spade Connectors: 

IMPORTANT: Make sure the (+) and (-) spade connector blades do not touch each other or the other terminal. Touching blades can cause a short circuit that can damage your receiver or amplifier. 
Using Banana Connectors:

Bl-WIRE CONNECTION

The 4367 connection assembly has two sets of input terminals that are connected by jumper wires. The upper set of terminals is for high-frequency/ultrahigh-frequency drivers, and the lower set of terminals is for the woofer. 
This arrangement allows you to bi-wire the speakers using a single stereo power amplifier or two stereo power amplifiers. Bi-wiring can offer sonic advantages and more flexibility in power-amplifier selection over a conventional single-wire connection. 
To bi-wire the 4367, first remove the terminal jumper wires as shown in the illustration.

If you're bi-wiring with a single stereo power amplifier, connect the speakers according to the following illustration.

If youore bi-wiring with two stereo power amplifiers, connect the speakers according to the following illustration.

In either case, follow the instructions for the different connector types in Basic Single-Wire Connection, on page 4.
NOTE: For more information about various speaker-wire and connection options, contact your local JBL dealer.

CONTROLS/ADJUSTMENTS

The 4367 has stepped front-panel adjustments that let you balance the high-frequency (HF) range and ultrahigh­frequency (UHF) range against the woofer.

You can use these controls to adjust the speaker's sound according to your roomcs acoustics or your personal taste. If you want to return the speakers to their factory-shipped response, set the controls to "O dB". 
As with most speakers, the 4367 has transducers whose suspensions will take several weeks to "break in" and achieve optimum performance. During this period, the balance between the woofer, HF and UHF drivers may change, so we recommend that you adjust the HF and UHF controls accordingly.

Setup Guide

To set up the JBL Harman 4367, 

1. Begin by carefully unpacking and inspecting the speakers for any damage. 
2. Place the speakers on stable stands or platforms to ensure optimal performance. 
3. Connect the speakers to your amplifier using high-quality speaker cables, ensuring proper polarity. 
4. For bi-wiring or bi-amping configurations, use the dual binding post pairs provided. 
5. Adjust the placement of the speakers in your room to achieve the best possible soundstage and balance.

CARING FOR YOUR SPEAKERS

• Wipe the cabinet with a clean, dry cloth to remove dust. A damp cloth may dull the cabinet's finish. Do not use volatile liquids such as benzene, paint thinner or alcohol on the cabinet.
• Do not spray insecticide near the cabinet.
• To remove dust from the grille fabric, use a vacuum cleaner set to low suction.
• Do not wash the grille in water, as water may fade the grillecs color or make it uneven.
• If the surface of the woofer cone becomes dusty, you can carefully sweep it clean with a soft, dry calligraphy brush or paint brush. Do not use a damp cloth.

JBL Harman Speakers 4367 Troubleshooting

If you encounter issues with your JBL, 

1. Check for common problems such as loose connections or improper polarity. 
2. Ensure that the speakers are placed in an optimal position within your listening space to avoid sound reflections and resonances. 
3. If you experience distortion, check your amplifier settings and ensure it is not overdriven. Always refer to the user manual for specific troubleshooting instructions.
