The subwoofer produces quality sound in both music and cinema mode. The heavy and durable subwoofer enclosure looks neat and compact in appearance. I liked the design of the SVS SB-1000: it does not look catchy, but it is modern. SVS PB-1000 vs Polk Audio PSW505 has RCA outputs. There is also a stereo low-level output with a fixed cutoff frequency of 80 Hz. 10-inch driver size and 300 W of power allow you to use it in rooms of different sizes. The built-in SVS Sledge STA-300D amplifier operates in class D and produces more than 700 watts in peak. It has a built-in digital processor, which coordinates the work of the speaker with the body and helps to obtain a linear response characteristic.
Polk Audio PSW505 vs SVS PB-1000 has a 12-inch driver size, and it does a great job of playing music. PSW505 is a great sub, with deep lows and clear sound. Good for both home theater and music. The case is made of 18 mm MDF, while the thickness of the front panel reaches 1-inch – an effective method of attenuation vibrations. High-amplitude inputs and outputs (screw terminals) are shorted in pairs. There are two line inputs plus an LFE input for the special signal from the AV receiver.
