Polk Audio PSW505 - best overall

Our rating
7.6/10

Polk Audio PSW505

The presented model is the best subwoofer under 300. This decision was caused by the fact that the driver located on the front panel of the American subwoofer makes a great impression. The 300th head with a cellulose diffuser coated with a polymer layer, a flat central dustproof insert, and a wide polymer suspension. The magnetic screen allows you to place the device close to the TV or even use it as a stand under 25 ".

The case is made of 18 mm MDF, the thickness of the front panel reaches 25 mm - an effective method of attenuating vibrations. The walls are covered with tinted oak veneer, and a Slot Load Vent is arranged in the lower part of the rear panel, designed to minimize the spurious noise of the airflow. High-amplitude inputs and outputs (screw to lemmas) are pairwise shorted, there are two linear inputs plus an LFE input for a special signal from an AV receiver. The on-board amplifier develops power up to 300 W in continuous operation at peak 460 - very good for the AV class. The weight of the device, of course, is not small - a transformer power supply is large. There is a mode of automatic inclusion "on signal," and the subwoofer is turned off when it is absent for 15 minutes, the casing is mounted on metal supports. Polk Audio PSW505

It is enough to touch the volume control just a little to make sure the power of the “beast” under the hood and to stop further advancement of the gain knob when setting up the subwoofer for playing in combination with small satellites: a friendly, reliable, harmonious ensemble is formed. However, we note that if the low-frequency potential of the satellites allows, you should try to tune the subwoofer band as much as possible - in order to achieve maximum bass clarity and clarity of the lower middle. In broadband mode, at a very low volume, the sound loses its support, with an increase in level, an emphasis appears in the upper part of the bass register. In the movie, you can operate on the volume level more freely. The sub does not dig very deep, but the relevance of low bass for real home conditions is a big question. The PSW505 is the best powered subwoofer under 300 with a solid power reserve.

The woofer is loaded on a bass reflex, the outlet of which is located on the rear panel of the subwoofer.

The power of the built-in Klipsch R-10SWi amplifier is 150 W (nominal value), and due to the work in the economy class D, it practically does not heat up even with prolonged use of the subwoofer. A feature of this model is the ability to wirelessly connect to a signal source, which further simplifies the placement of the Klipsch R-10SWi in the listening room. The receiver is built into the subwoofer, and the transmitter included in the kit must be connected to the line or LFE outputs of the AV receiver or stereo amplifier. The signal is transmitted at a frequency of 2.4 GHz, while the connection occurs automatically after turning on the subwoofer. Klipsch R-10SWi also provides traditional line / LFE inputs.

This device is a powerful subwoofer with an effective output and a powerful amplifier. It is primarily designed to provide deep and detailed bass, but it also works quite well at high frequencies.

Polk Audio PSW125

Our rating
7.3/10

Polk Audio PSW125

The Polk Audio PSW125 subwoofer is equipped with a large 12-inch diameter woofer and a powerful 300-watt amplifier and is designed to sound large rooms. The sub is made in a housing made of MDF, which has a high-quality external finish, and, despite its considerable physical dimensions, does not look bulky. This is achieved thanks to the neatly rounded corners of the case, as well as a round protective mesh that hides the speaker on the front panel. The subwoofer is equipped with internal ties that eliminate the vibrations of its walls and are mounted on high conical supports.

The Polk Audio PSW 125 is equipped with a 12-inch diameter woofer with a composite diffuser whose electromagnetic system has been optimized by computer simulation for maximum efficiency. A precisely calculated suspension, a massive non-resonating basket, and a powerful magnet provide the dynamics of perfect reproduction of low frequencies without audible distortion. In general, the design of the subwoofer is made in accordance with the patented Dynamic Balance technology, which provides for the coordination of all key elements of its design. As with the other models in the series, the Polk Audio PSW 125 is equipped with a bass reflex unit with an outlet open to the floor. In this case, not only the optimal expansion of the bass range is achieved, but also a uniform distribution of low frequencies in the listening room, which is practically independent of the location of the subwoofer itself. Polk Audio PSW125

Another distinctive feature of the Polk Audio PSW 125, as well as other subs of this line, is the ability to connect to all three input options - stereo linear, low-frequency LFE, and acoustic. The latter can come in handy when connecting the subwoofer to a conventional stereo integrated amplifier, not equipped with a special output.

  • The subwoofer features a robust design and organically complements the high-end audio system
