DOCUMENTATION CONVENTIONS This document contains general safety, installation, and operation instructions for the Revel Concerta F12 Floor-Standing Loudspeaker. It is important to read this document before attempting to use this product. Pay particular attention to safety instructions. WARNING Calls attention to a procedure, practice, condition, or the like that, if not correctly performed or adhered to, could result in injury or death.
ABOUT THE F12 Thank you for purchasing the Revel Concerta F12 Floor-Standing Loudspeaker. A full-frequency reproducer, the F12 delivers accurate performance with wide frequency range, low distortion and high output across the entire audible spectrum. F12 loudspeakers are ideally suited as main speakers in stereo system setups or as the front speakers in a multichannel surround home theater installation.
Since 1996, Revel has stood at the forefront of loudspeaker design. Backed by Harman International’s extensive research and design facilities, the Revel Concerta Series Loudspeakers benefit from cutting-edge development tools. A multi-channel listening lab allows for double-blind listening tests. A laser interferometer enables detailed driver and cabinet analysis. Multiple large anechoic chambers provide for precise tests and measurements. Finite element analysis allows for advanced loudspeaker modeling.
Figure 1: Unpacking the F12 Figure 2: Lifting the Carton 2 3 1 TOP Unpacking (continued) 2. Without allowing the top flaps to close, stand the packing carton upside-down as shown in Figure 1 (above). 3. Lift the packing carton off of the loudspeaker as shown in Figure 2 (above). Use caution to avoid damaging the loudspeaker cabinet. At this point, the loudspeaker will be upside-down. 6. When the F12 is in the upright position, remove the Owner’s Manual, Warranty Card and Spikes. 7.
LOUDSPEAKER OVERVIEW Figure 4: F12 Loudspeaker (Front View) DRIVER COMPLEMENT The numbers in Figure 4 (left) correspond with the numbered items below. 1 1. Tweeter 2 2. Midrange 3. Woofers CABINET 3 Reduces cabinet-induced colorations with MDF walls. Rubber feet/spikes are attached to the bottom of the cabinet for optimal stability, accommodating installations on tile, hardwood, and carpeted floors. The cabinet’s vinyl finish does not require routine maintenance.
Figure 5: F12 Loudspeaker (Rear View) 2 3 3 2 1 The numbers in Figure 5 (above) correspond with the numbered items in the Rear Panel section that begins below. FILTER NETWORK Optimize loudspeaker on-axis and off-axis response with high-order filters at 575Hz and 3.0kHz, helping to ensure smooth octaveto-octave balance and timbral accuracy. Removable shorting-straps and gold-plated binding posts accommodate single-wired, bi-wired and bi-amplified connections.
INSTALLATION CONSIDERATIONS Figure 6: Loudspeaker Placement Loudspeaker fidelity depends on the following three factors: 1. Loudspeaker accuracy 2. Loudspeaker placement 3. Listening room acoustics Advanced Revel design features allow the F12 to achieve exceptional acoustical precision. As a result, experimenting with loudspeaker placement and listening room acoustics have the most significant impact on the F12 loudspeaker’s performance.
Listening Room Acoustics (continued) 1. Surfaces and other boundaries often cause large peaks and dips in lowfrequency extension. These peaks and dips often range 12dB or more. 2. Standing waves (also known as room modes or resonances) interact with both the loudspeaker and the listener, resulting in large frequency response errors. Unfortunately, there is no simple solution that considers both factors.
Figure 7: Adjustable Spike feet When shipped, the rubber feet are attached as shown here for loudspeaker placement on tile or hardwood floors. The spikes should be inserted as shown here for loudspeaker placement on carpeted floors. (Threaded into Center of Foot) To install the spikes: 1. Place the F12 on its side on a soft towel or carpeted floor. 2. Rotate the spike clockwise into the threaded insert in the center of a rubber foot, round end first, as shown on the right side of Figure 7 (above). 3.
MAKING CONNECTIONS The F12 features gold-plated binding posts and shorting-straps that allow it to be configured for single-wired, bi-wired or biamplified connections. channel. Otherwise, each power amplifier can be connected to a separate connector for the same output channel of the preamplifier. • CAUTION • Never make or break connections unless all system components are powered off.
SINGLE-WIRED CONNECTIONS BI-WIRED CONNECTIONS Single-wired connections are made between one F12 input channel and one power amplifier output channel as shown in Figure 8 (below). Bi-wired connections are made between both F12s and one power amplifier as shown in Figure 9 (below). To make single-wired connections: 1. Leave the shorting-strips identified in Figure 5 (page 9) in place as shown in Figure 8 (below). 2. Connect one pair of loudspeaker wires to the desired F12 input connectors.
VERTICAL BI-AMPLIFIED CONNECTIONS Vertical bi-amplified connections are made between both F12s and two separate power amplifiers. Each F12 is connected to its own power amplifier, which sometimes increases sonic performance. These power amplifiers must be identical. Vertical biamplified connections are shown in Figure 10 (below). Note When making vertical bi-amplified connections, both power amplifiers must receive identical input signals from the associated pre-amplifier.
HORIZONTAL BI-AMPLIFIED CONNECTIONS To make horizontal bi-amplified connections: Horizontal bi-amplified connections are also made between both F12s and two separate power amplifiers. The F12 input connectors labeled HF (High Frequency) are connected to one power amplifier, while the F12 input connectors labeled LF (Low Frequency) are connected to another power amplifier, which sometimes improves sonic performance.
Note Horizontal bi-amplified connections can be made using identical or dissimilar power amplifiers. However, these power amplifiers must have identical “gain factors.” If the gain factors are dissimilar, a means of adjusting the input level of at least one power amplifier is required. Contact an authorized Revel dealer for assistance. 5. Repeat step 3 to connect the input connectors labeled LF (Low Frequency) on the second F12 to the same power amplifier that was selected in step 3.
SPECIFICATIONS Specification Value Definition Indicates the amount of power the associated power amplifier must deliver to drive the loudspeaker at reasonable volume levels. Conservatively-rated specifications indicate moderate sensitivity, meaning that a massive power amplifier is not required to drive Revel loudspeakers to reasonable volume levels in large listening spaces. Sensitivity 90.5dB SPL with 2.83V @ 1m (2 pi anechoic) Impedance 6Ω (nominal), 3.
