Overview
Not a powered soundbar or a pair, this is one tower with a Terylene tweeter, two polypropylene woofers and cascading crossovers. The Power Port extends the bass port for louder, cleaner low notes, and an AVR or amplifier drives it.
Choose it as one channel of a growing home theater, since the description names matching surround and center models for a full surround setup. The limit is that one tower is sold at a time, so a stereo pair means buying two, and several listing fields read as errors.
Who it's for
A home theater or music listener with an AVR and room for a floorstanding speaker will use the tall cabinet and the matched-series design. Buyers who want a pair out of one purchase, a powered speaker or wireless streaming should look elsewhere.
Pros and cons
- Two woofers and a tweeter
- Power Port bass enhancement
- Hi-Res Audio Certified
- Matches other series models
- Sold singly, not as a pair
- Frequency response field is garbled
- Several fields look like errors
- Needs a separate amplifier
Performance notes
Two woofers and a tweeter divide the sound across the crossovers, so the bass drivers handle low notes while the tweeter handles detail. The Power Port moves more air for bass, which helps a tower fill a room, though a subwoofer still helps the lowest notes. Amplifier power and room placement set the final result.

Frequently asked questions
Does the Polk Signature Elite ES50 come as a pair?
No. The title says Single, so one tower is in the box. A stereo pair means buying two.
What do I need to run the Polk ES50?
An AVR or amplifier. The description mentions AVRs and amplifiers, and speaker cables are not named in the listing.
Which other Polk models match the ES50?
The description names the ES10 surround pair and the ES30 center channel, plus any sub, for a 5.1 surround setup.
Does the Polk ES50 have XLR or HDMI inputs?
The connectivity protocol field lists Aux, RCA, XLR, Coax and HDMI, which does not fit a tower speaker. Treat it as an error and confirm the inputs with Polk.
