Our take on the Infinity PS28 by Crutchfield's Loren Barstow
Enjoy hard-hitting, accurate bass with the PS28 from Infinity. This capable sub features an 8" woofer powered by a 150-watt amp to add impact and realism to all of your movies, music, and video games. Easily accessible controls on the back of the cabinet make it a cinch to add as little or as much bass as you like, and to blend the sub in with the rest of your system.
Infinity's lightweight and responsive M.M.D. driver material uses a stiff aluminum core for added rigidity. That means that the woofer keeps its shape as it moves, for rich and detailed lows.
I really enjoy the sound that my Infinity PS28 delivers and the ease of installation.

Metal Matrix Diaphragm (M.M.D.): Derived from the C.M.M.D. material used in Infinity's flagship Cascade series, M.M.D. features a stiff aluminum core, anodized on both sides for increased strength and rigidity. M.M.D. transducers conduct sound faster than paper, polypropylene, and Kevlar, pushing unwanted resonances beyond the operating range of the transducer. M.M.D. drivers deliver crystal-clear, distortion-free sound from dynamic digital sources, even at high listening levels. The PS28 is equipped with a front-firing, 8" M.M.D. woofer.
Amplifier: This subwoofer is powered by a 150-watt (RMS) amplifier, rated at 35Hz - 150Hz with no more than 0.1% THD. The maximum (peak) power output is 300 watts.
Surround: For a smoother response and improved durability, the woofer uses a rubber surround.
Bass Ports: There are two rear-firing bass ports that allow deep bass with high acoustic efficiency and low distortion.
Gain Control: The subwoofer has a rotary control on the rear panel for adjusting the level of the bass.
Phase Switch: The subwoofer's phase switch allows you to control the phase of the subwoofer's output relative to the front speakers. If the bass sounds muddy or unclear, toggling the phase control can sometimes strengthen the bass "attack."
Auto On/Off Circuit: The auto on/off circuit turns the power amp on when a signal is sensed and turns the amplifier off and into standby mode approximately 10 minutes after a signal is no longer received. An LED indicator on the rear panel glows green when the amplifier is on and red when the amp is in standby.
Low-Pass Crossover: The subwoofer features a continuously variable 50Hz-150Hz low-pass crossover that determines the highest frequency at which the subwoofer reproduces sounds. The crossover has a 24dB/octave slope. Note: The crossover is bypassed when the "LFE" input is used.
Line-level Inputs: The subwoofer has a gold-plated LFE input (single RCA) and gold-plated stereo RCA inputs. If you have a Dolby Digital/DTS receiver or processor with a low-frequency-effects (LFE) output, you should use the LFE input on the subwoofer. If your receiver/processor does not contain a Dolby Digital or DTS processor but has a subwoofer output, you must use the stereo RCA inputs. If the receiver/processor has a mono subwoofer output, a "Y" adapter is recommended to maximize performance.
