Wireless Operation and Other Features
The Infinity PS210W has a 10-inch MMD™ front-firing woofer with a 300-watt RMS amplifier. MMD™ is Infinity's proprietary Metal Matrix Diaphragm, an ceramic-aluminum cone anodized on both sides to increase stiffness. The MMD cone is similar to the CMMD™ cones used in Infinity's Classia line of floorstanding and bookshelf speakers. A down-firing port vents some of the bass into the room.The PS210W can be used wired or wirelessly. The wireless feature uses a 2.4GHz transmitter with a 75' range depending on walls or other obstacles. The 5"W x 4"D x 1"H transmitter easily fit on my equipment rack and it comes with a bracket to mount it to a wall or other surface. The sub and transmitter have four selectable channels, useful if you have more than one wireless sub or if you experience radio interference with another wireless device. Both must be set to the same frequency.
For wireless use, the subwoofer/LFE output of the receiver connects to an RCA input jack on the transmitter and the signal is transmitted to the subwoofer via a small antenna. The Infinity PS210W can be used only with receivers that have a subwoofer or LFE output because the system has only low-level inputs and no speaker level inputs.
The crossover frequency is continuously variable from 50Hz to 150Hz with a 24dB/octave filter and has a switch to deactivate the subwoofer crossover if you want to use the crossover in the receiver.
The subwoofer has an Auto On/Standby feature that will turn off after approximately 10 minutes if no signal is detected.
The PS210W has a black ash finish.
Audio and Wireless Performance
Two design aspects of the Infinity PS210W make it easy to place and enhance its audio performance. First, its wireless capability means it can be placed almost anywhere in the room without the constraints of wires (except the 120V AC connection). The performance of a subwoofer is highly dependent on correct placement and wireless transmission of the audio signal allows more placement flexibility.Second, its front-firing woofer and down-firing port seems to benefit its audio performance by reducing boominess and the typical room resonance problems. I found the PS210W to have deep, solid bass with both stereo and multichannel sources. The down-firing port seemed to diffuse the subwoofer's output and distribute bass more evenly throughout the room resulting in fewer peaks and dips that commonly plague good subwoofer performance. It was also easy to integrate the subwoofer with the multiple speaker systems I used during this review ranging from in-wall, floorstanding, bookshelf and planar magnetic speakers. In all cases the Infinity sub blended well with the main speakers.
A down-firing port will work better on carpeted floors than hard surfaces, such as hardwood floors or tile. If used on a hard surface, place a small piece of carpet or foam beneath the port to prevent bass reflections.
Conclusion
A down-firing port will work better on carpeted floors than hard surfaces, such as hardwood floors or tile. If used on a hard surface, place a small piece of carpet or foam beneath the port to prevent bass reflections.Its affordable price makes it a good choice if you are considering the benefits of using multiple subwoofers. One subwoofer is certainly adequate but two of the Infinity subwoofers would easily fill a medium sized listening room and provide very even distribution of bass.
