CAUTION Note 4 REVEL Concerta C12 Owner's Manual ABOUT THE C12 Thank you for purchasing the Revel Concerta C12 Center-Channel Loudspeaker. The C12 delivers an impressively clear soundfield with excellent acoustical accuracy across a wide dynamic range, making it the perfect complement to the Revel Concerta F12 and M12 Loudspeakers in surround sound home theaters. Four proprietary transducers, sophisticated filter networks, and flexible placement options allow the C12 to serve as a full-frequency centerchannel in the most demanding home entertainment systems. [. . . ] Remove the left and right pads and the grille identified in Figure 2 (right). Remove the Owner's Manual, Warranty Card and rubber pad feet as identified in Figure 2 (right). Then place the C12 in the upright position. REVEL Concerta C12 Owner's Manual 7 LOUDSPEAKER OVERVIEW Figure 3: C12 Loudspeaker Front View CAUTION To prevent cabinet damage, do not use a cloth made with steel wool or use metal polish to clean the cabinet. 1 1 2 Do not use any cleaning products or polishes on the cabinet or grille. FILTER NETWORK Optimize loudspeaker on-axis and off-axis response with high-order filters at 500Hz and 2. 8kHz, helping to ensure smooth octave-to-octave balance and timbral accuracy. Gold-plated binding posts accommodate heavy speaker cables. 3 The numbers in Figure 3 (above) correspond with the numbered items in the Driver Complement section that begins below. INPUT PANEL The numbers in Figure 4 (page 9) correspond with the numbered items in this section. DRIVER COMPLEMENT The numbers in Figure 3 (above) correspond with the numbered items in this section. 1. Input Connectors Provide input connections from the associated power amplifier. One "positive" and one "negative" gold-plated binding posts are available. Refer to the Making Connections section that begins on page 11 for additional information. 1. Midrange CABINET Reduces cabinet-induced colorations with thick MDF walls and internal bracing. An adjustable tilt foot is shipped attached to the cabinet to provide an optimum tilt angle when the C12 is placed on or above a video monitor. However, cabinet surfaces that have been marked with fingerprints, dust, or other dirt can be cleaned using a soft cloth. 2. Adjustable Tilt Foot Provides an adjustable tilt angle if the C12 is mounted on top of a monitor or shelf for optimum sound quality. See page 10 for more information. 8 REVEL Concerta C12 Owner's Manual Figure 4: C12 Loudspeaker Rear View 1 2 proximity to the C12. These magnetic fields decrease rapidly with distance, so moving the C12 farther away from the monitor will reduce interference. It is important to confirm that the C12 is suitable for use with the intended CRT monitor. Note The numbers in Figure 4 (above) correspond with the numbered items in the Input Panel section that begins on the previous page. DLP, LCoS and Plasma display devices are not affected by magnetic fields. LOUDSPEAKER PLACEMENT Loudspeaker fidelity depends on the following three factors: 1. Loudspeaker placement ON TOP OF MONITOR The C12 loudspeaker can be placed on top of a video monitor or a shelf as shown in Figure 5 (below). The loudspeaker should be tilted to align the tweeter with the listener's head. Figure 5: On Top of Monitor Advanced Revel design features allow the C12 to achieve stunning acoustical precision with exceptional freedom from coloration and distortion across a wide dynamic range. As a result, experimenting with loudspeaker placement will have the most significant impact on the C12's performance. The bulleted items that begin below indicate important placement considerations for the C12. In general, it is recommended to: · · · Aim the C12 directly toward the primary listening position Remove all obstructions between the C12 and the primary listening position Align the front edge of the C12 with the front edge of your TV screen. The C12 is magnetically shielded to minimize any effect on CRT video monitors. However, stray magnetic fields may affect large CRT monitors located in close REVEL Concerta C12 Owner's Manual 9 Adjustable Tilt Foot The adjustable tilt foot is attached to the rear of the cabinet identified in Figure 4 (page 9). Use the tilt foot to achieve the proper tilt angle when the C12 is placed on top of a video monitor or shelf as shown in Figure 6 (right). Turn the foot knob counterclockwise to loosen and extend the tilt rod to create a tilt angle as shown in Figure 6 (right). [. . . ] A breakthrough measurement, this specification closely correlates to sound quality in a single curve ­ a long-standing goal of loudspeaker engineers. In-room response is measured through the use of large anechoic chambers. The speaker's response is measured every 10 degrees horizontally and vertically for a total of 72 response measurements. The in-room response curve is a prediction of how the speaker would measure in a typical room. [. . . ]
