Our take on the Klipsch SW-308 by Crutchfield's Kristen Schaub
Save space and get big bass
You'll definitely feel the deep, intense bass that this little sub pumps out but will you see it? Maybe if you know where to look. The Klipsch® SW-308 sports a high-output 300-watt amplifier to produce accurate, room-filling bass unexpected from a sub so small. The strong-yet-light 8" woofer is designed for quick, precise movement. It teams up with an 8" passive radiator that creates an extra mid-bass boost. And since this sub measures only about a cubic foot, you won't have any trouble finding room for it under a coffee table or next to your sofa.
Coupled with the Quintets, this subwoofer seems to blend nicely so far. Only have had it for about a month but sounds clean so far.

BASH Digital Hybrid Class AB Amplifier: The Klipsch SW-308 powered subwoofer features a highly efficient BASH digital hybrid class AB amplifier which produces reliable, high-powered sound. The built-in amplifier is rated at 300 watts RMS (650 watts Peak). The RMS power rating indicates power available on a continuous, long-term basis. The Peak power rating indicates power available for large, short-term peaks in your music or movie soundtrack.
Digital Sound Processing: The Klipsch SW-308 utilizes internal digital sound processing for optimum sound at all volume levels.
8" Fiberglass Woofer: The Klipsch SW-308 powered subwoofer features a front-firing 8" woven fiberglass driver for tight musical bass. The woofer employs a large 4-layer aluminum-wound voice coil for high volume output.
Passive Radiator Design: The Klipsch SW-308 powered subwoofer features a passive radiator design which employs dual side-firing 8" woven fiberglass passive radiators for greater bass reproduction.
Computer Optimized Surrounds: The SW-308's woofer & passive radiators utilize computer optimized rubber surrounds for tighter bass.
Power LED Indicator: Located on the powered subwoofer's front baffle, this LED indicates the operating status of the unit's built-in amplifier. The LED will light red when the amplifier is in standby mode and green when the amplifier is on and receiving a signal. If the LED is dark and not lit, the amplifier is off.
Rubber Feet: The Klipsch powered subwoofer is equipped with four integrated rubber feet to help prevent against vibration.
Placement: Klipsch powered subwoofers are designed to reproduce deep bass and deliver the impact that makes your movies and music come alive. Typically, optimum performance will result if you place the subwoofer in a corner of the room on the same wall as your front channel speakers.
Gain Control: The gain control of the Klipsch SW-308 adjusts the subwoofer's volume relative to the rest of your home audio system. If the Klipsch powered subwoofer is connected to the Subwoofer Output (LFE) on your AV receiver, first set the subwoofer volume level control in the receiver to the "half-way" or the "0-dB" position. Then increase the gain of the subwoofer until the subwoofer's volume level matches the output of your main speakers. After this setup is completed, the volume control of your AV receiver will be the volume control for both the Klipsch powered subwoofer and your connected loudspeakers.
Lowpass Crossover: The Klipsch SW-308 powered subwoofer features a variable lowpass crossover which is adjustable from 40-150Hz. The crossover point chosen determines where low bass frequencies are "handed-off" from your AV system's loudspeakers to the Klipsch powered subwoofer. Set the crossover point based on the size of your systems' main left/right speakers. As a general rule, for larger, floor-standing speakers, set the crossover point between 50-90Hz. If using small bookshelf or satellite speakers for your mains, set the crossover point between 90-150Hz. The smaller the speaker, the higher the setting until the bass frequencies blend well between the loudspeakers and the Klipsch powered sub. If setting the crossover point in the receiver, turn the Lowpass Filter knob on the subwoofer to the farthest point right (150Hz).
Phase: The Klipsch SW-308 powered subwoofer has an adjustable phase control which can be set between 0° and 180°. This control is used to acoustically match the subwoofer's output to your system's main speakers. Select a position between 0° and 180°, in which the subwoofer has more output at your main listening position.
Power Auto/On/Off: The Klipsch powered subwoofer features a 3-way power switch. This is the main AC power switch for the subwoofer. This switch must be in the "On" position for the subwoofer to operate or the "Auto" position for the Auto-On feature to function. Set this switch to the "Off" position if the subwoofer will not be used for an extended period of time. When this switch is in the "Auto" position, the subwoofer will automatically turn on when it senses a signal. It will automatically turn off after 20 minutes with no signal.
Line-Level Input: The Klipsch SW-308 powered subwoofer is equipped with a pair of line-level RCA-type inputs. Most of today's AV receivers have a line-level subwoofer output (LFE) labeled Subwoofer Pre Out, Sub Out, or SW Out. If your receiver has this output, connect on end of a subwoofer cable to it and connect the other end of the cable into the powered subwoofer's line-level input labeled "LEFT/LFE". This connection allows the subwoofer to operate with both music and surround sound movies. In absence of a subwoofer (LFE) output on your receiver, as an alternative hookup, you can connect Left & Right channel pre-amp outputs from a receiver to the "Left/LFE" and "Right" input on the powered subwoofer.
WA Port (optional): The Klipsch powered subwoofer is fitted with a proprietary 4-pin "WA-Port" connector for wireless operation, using Klipsch's optional WA-2 wireless subwoofer kit (714WA2, sold separately). The Klipsch WA-2 wireless subwoofer kit consists of two components; a wireless Transmitter & wireless Receiver. The WA-2 wireless subwoofer kit makes adding the Klipsch powered subwoofer to your home theater system much easier, because it replaces the need for a separate subwoofer cable that traditionally must be connected between the receiver and the powered sub. Now, you can easily place your powered subwoofer where it both sounds and looks best in the room since you're not restricted by an audio cable.
