[. . . ] The toe-in angle can be reduced to widen the soundstage, even to the point at which the F32s are pointing straight forward. Move the F32s farther from the front and side listening room walls to improve stereo imaging and the sense of spaciousness in the listening space. Move the F32s closer to the corners or walls of the listening room to increase bass response. · · 11 Acoustic Treatment Materials The F32 features high-order filters at 220Hz and 2. 8kHz that optimize loudspeaker on and off-axis response, minimizing degradations that occur in overly "live" rooms. Placing acoustic treatment materials at primary reflection points will reduce these distortions even further. Ideally, acoustic absorbers should be placed at the first reflection points on the front and side walls and either acoustic absorbers or diffusers should be placed at the first reflection point on the rear wall. Because the listener's eyes and ears are on the same plane, the "mirror method" is an accurate determinant of critical reflection points. This method can be used to determine reflection points for side walls, rear walls, front walls, and even the ceiling. Applying acoustic treatment materials to the side walls is most important, followed by the front wall, rear wall, and ceiling. Once the F32s have been placed, sit in the primary listening position. Note the locations at which the person sitting in the primary listening position can see either F32. Be sure to look for both F32s in the reflection on each room boundary. These are primary reflection points that will most benefit from acoustic treatment materials. If acoustic treatment materials are not available, hanging a rug over the reflection points will help to reduce degradation in overly "live" rooms. Carpeting the floor between the loudspeakers and the primary listening position and placing irregular surfaces such as bookcases at first reflection points will also help minimize strong reflections. ADJUSTABLE SPIKE FOOTING When shipped, adjustable spike footing is attached to the bottom of the cabinet for optimal stability, accommodating installations on tile, hardwood, and carpeted floors. The F32 is shipped with spike footing attached as shown on the left side of Figure 7 at the top of the next page, with the round end protruding from the cabinet. The protective cap is placed over the round end to protect tile and hardwood floors. Note When moving the F32, do not drag it across the floor. If the F32 is placed on a carpeted floor, the spike footing should be adjusted as shown on the right side of Figure 7 (next page), with the spike end protruding from the cabinet. If needed, follow the instructions that begin below to adjust the spike footing. Rotate the spike clockwise into the cabinet, round end first, as shown on the right side of Figure 7 (next page). 12 Figure 7: Adjustable Spike Footing F32 Spike End Round End Protective Cap When shipped, the spikes are attached as shown here for loudspeaker placement on tile or hardwood floors. The spikes should be attached as shown here for loudspeaker placement on carpeted floors. Spike End Locking Ring Round End (Protective Cap Attached) Round End (Protective Cap Removed) Locking Ring Spike End 6. Reattach the locking ring, rotating it clockwise to firmly secure the spike to the cabinet. When all four spikes have been reversed, stand the F32 in the upright position. Repeat these steps to adjust the spike footing on the other F32. CAUTION Floor-standing loudspeakers such as the F32 have a high center of gravity, which may cause them to fall if tipped or improperly positioned. To avoid this, anchor the loudspeaker to the floor and/or wall using the same procedures and hardware used to anchor bookcases, wall units, and other furniture. Harman Specialty Group assumes no responsibility for proper selection and installation of hardware or for any personal injuries or product damages resulting from improper installation or a fallen loudspeaker. 13 MAKING CONNECTIONS The F32 features gold-plated binding posts and shorting-straps that allow it to be configured for single-wired, bi-wired, or bi-amplified connections. · Use high-quality loudspeaker cable with a maximum total loop resistance of 0. 07ohms or less (for each wire run). [. . . ] Indicates whether the loudspeaker presents a "difficult" or "easy" load on the associated power amplifier. Combined with moderate phase angles, a minimal impedance specification of 3. 7 allows a reasonably designed power amplifier to drive Revel loudspeakers. Steep filters indicate an optimized filter network that produces minimal acoustical interference, low distortion, and expansive dynamic range. Woofer, midrange, and tweeter filter boards are independent of one another. [. . . ]
