User manual KLIPSCH KSB-S1

[. . . ] ⷠThe subwoofer's output will increase as it is moved closer to walls, with maximum output achieved when it is placed in a corner. If practical, always place the subwoofer against or near a wall. ⷠIn most rooms, a subwoofer will deliver smoothest bass response when placed in a corner away from room openings, such as doors. ⷠIf you are using more than one subwoofer, you will usually achieve the best performance by placing them together in the same area rather than by spacing them apart. [. . . ] refer to the adjustment section for more information. In that case, start with the frequency that comes closest to matching the specified low-frequency limit of the smallest speakers in the system. After completing the other adjustments, you may want to experiment with moving the frequency up and down a little, to see if a different setting works slightly better. If the crossover frequency is set higher than 100Hz, the subwoofer should be in the front of the room near the front main speakers. Volume Control -- Adjust the subwoofer's Level to get a smooth transition between its output and that of the main speakers. Your receiver or processor will have a subwoofer level control in its speaker setup menu, so you will have to go back and forth a bit between it and the Level control on the subwoofer itself. In the end, you should wind up with the menu control somewhere in the middle of its range. strive for bass that is solid but not overblown or boomy. Phase Control -- In some installations the setting of the Phase Control may not make much difference, whereas in others it may be necessary to go back and forth between the Phase and the Level controls for a while in order to get the very best blend with the main speakers. Since each control setting (including the one for crossover frequency in the receiver or processor) affects the optimum settings for the others, it often takes a while to get everything dialed in just right. Start with the phase knob at 0° and play a recording with a prominent, repeating bass line in your listening position. Play a variety of music recordings containing strong but not overpowering bass. Adjust the subwoofer's Level control until the music sounds consistently warm and natural. If you have trouble getting enough low bass without the sound becoming boomy, it probably means the Crossover Frequency is set too high. Try turning it down a bit at a time until the problem goes away. If the sound is thin until you turn the subwoofer Level up so much that the lower bass is too prominent, start by varying the setting of the Phase control. If that does not entirely solve the problem, you probably need to raise the Crossover Frequency. General Comment About Adjustments: Since any change in the setting of one control tends to change the optimum settings for the others to some degree, the adjustment process is very interactive and involves a great deal of trial and error. If after a period of listening and calibration you're still not happy, it may mean that you need to experiment a little with the location of the subwoofer. CARE AND CLEANING The only thing you should ever need to do to your subwoofer is to dust it occasionally. Never apply any abrasive or solvent-based cleaner or any harsh detergent. You can clean the grille with the brush attachment of a vacuum cleaner.
