Affordable Power, Unforgettable Sound: Which Polk 5.1 System Is Right for You?


Why Polk makes sense for real homes

Surround sound shouldn’t be complicated or costly. Polk Audio delivers big, cinematic sound at realistic prices. Three 5.1 packs, three budgets, one goal: make movies, TV, and games feel alive in your room.


What “value without compromise” means here

Clear dialogue, punchy bass, easy setup. Cabinets built to last. Sensible upgrades as you move up. No gimmicks—just performance that scales with your space and budget.

All three packs are true 5.1: front left/right, centre, surrounds, and a subwoofer for low-end impact.

Set-up tips for instant results

  Place fronts at ear height and angle slightly toward the sofa

  Keep the centre speaker edge near the TV’s front edge to reduce reflections

  Position surrounds just behind and above ear height for better envelopment

  Start the subwoofer near a front corner, then fine-tune level and crossover in your AV receiver


Upgrade to Dolby Atmos

Probably the hottest topic in home cinema is Dolby Atmos, bringing more immersive sound experiences to your movie nights. Need to know more? Check out our guide.

So we'd be remiss to not include the option to upgrade any of the Monitor XT packs to Dolby Atmos. Add on the Monitor XT90 Atmos Speakers and make sure your AVR supports Dolby Atmos.
