Q: Does it come with a pair of speakers or just one?
A: While floor-standing models are often marketed as one unit, book shelf speakers are typically sold in pairs.
Q: How do the S20s handle high frequencies? Do the speakers sound warm or do they have any brightness?
A: Polks Signature series seems to be tuned to accurately reproduce reality when I listen to my S15 pair. At greater volumes, some people could describe their sound as bright, but it is not warm.
Q: What distinguishes these from the Polk Rti A3?
A: 50-26k Hz frequency response, 89dB sensitivity, 20-150W power range, and RTi A3, S20: power range of 20–125W, sensitivity of 88 dB, and frequency response of 39–40k Hz
Q: What are the Polk signature S20s exact three dimensions?
A: Both the front and back of them measure 15 inches tall. They are 8.75 inch broad. An exterior bass port construction is present at the rear that extends 1.5 inch outward from the main body and occupies roughly the upper 2/3 of the rear wall. The speaker and bass port extend 14 inch from the front of the grill to the back of the port, measured at the top. The only component at the bottom is the main enclosure case, which measures 12.5 inch from the grills front to its back.
Q: How do they stack up against the Elac 6.2? They are appropriate for stereo use.
A: They sound great when I use them for stereo purposes rather than home theatre.
Q: How much additional power is required for these Polk Audio S-20 speakers to provide high-quality sound?
A: They play nicely, loudly, and clearly with just 125 W per channel when I utilise that amount of power. 200w per channel would undoubtedly be preferable. I do not need to turn up the volume that much. These S20s have also been connected to a single 85w per channel receiver. Even with 85w, I was pleased with the sound it provided. Polk Speakers, including the Monitor/RTi and SDA series, can produce strong sound with just 50 to 100 watts of power.
Q: What distinguishes Polk Signature from Polk Signature Elite Speakers?
A: Since I have not heard the Signature Elite speakers, I would not be able to distinguish between the two in terms of sound quality. I do have the S20, and I am quite pleased and surprised with the sound these speakers produce. The woofers are nearly identical, and the tweeters share the same appearance. While the signature series is 125 watts, the signature Elite is rated at 150 watts. I do not think there is a very significant difference, and the sound quality would hardly be improved. Keep in mind that tone, not volume, determines what a sound is.
