Polk Signature Elite ES20

The 6.5-inch woofer and Power Port technology provide surprisingly deep, punchy bass for a bookshelf speaker. While they handle music and movies well on their own, adding a dedicated subwoofer is recommended if you want to feel the lowest cinematic rumbles in a larger room.

Yes, the ES20 speakers are compatible with most standard home theater receivers. With an 8-ohm impedance and 89 dB sensitivity, they are easy to drive and will work well with almost any modern amplifier.

Absolutely. Their compact size and balanced sound profile make them excellent candidates for rear or side surround channels, providing a seamless soundstage that matches well with other speakers in the Signature Elite series.

Hi-Res Audio certification means these speakers are capable of reproducing high-frequency sounds up to 40kHz. This results in a more detailed, airy, and lifelike sound, allowing you to hear subtle nuances in high-quality music recordings that standard speakers might miss.

Each speaker measures 14.5 inches tall by 7.5 inches wide. Because they feature a rear-firing Power Port, you should leave a few inches of clearance between the back of the speaker and the wall to ensure the bass can vent properly.

Like most high-quality speakers, the ES20s may sound slightly better after a few days of regular use. The materials in the woofer surround and spider will loosen up over time, allowing the speakers to reach their full sonic potential.
