Choosing Between Modern Bookshelf Speakers: A Detailed Comparison

When you're looking to upgrade your sound system, choosing between the Klipsch Reference Premiere RP-500M II ($419) and Polk Audio Signature Elite ES20 ($347) isn't a simple decision. Let's break down everything you need to know to make the right choice for your setup.

Understanding Bookshelf Speakers in 2023

Bookshelf speakers remain the sweet spot for many audio enthusiasts, offering a perfect balance between size and performance. They're called "bookshelf" speakers because they're designed to work well when elevated off the floor, though ironically, you probably shouldn't put them on an actual bookshelf (they need some breathing room for best performance).

Both these models represent recent updates to their respective product lines. The Klipsch RP-500M II launched in 2021 as part of Klipsch's Reference Premiere refresh, while the Polk ES20 arrived in 2022, bringing some meaningful improvements to Polk's already successful Signature series.

Sound Signatures: Two Different Approaches

Here's where these speakers really start to show their personalities. The Klipsch takes what audiophiles call a "forward" approach - imagine the music taking a step toward you, with details that pop out and grab your attention. Their signature horn-loaded tweeter (a special way of shaping how high frequencies spread into the room) gives vocals and instruments an engaging, live-performance feel.

The Polk ES20 takes a more laid-back approach. It's like sitting a few rows further back at the concert - everything's still clear and detailed, but it's presented in a more relaxed way. This doesn't mean it's less accurate; it's just a different presentation style that some listeners prefer.

Real-World Performance

Bass Response

Here's something interesting - despite being the smaller speaker, the Klipsch RP-500M II doesn't give up much in terms of bass impact. It reaches down to 50Hz, which covers most music pretty well. However, the Polk extends even lower to 41Hz, which lets you feel more of those deep bass notes in electronic music or movie soundtracks.

Think of it this way: the Klipsch gives you tight, punchy bass that works great for rock and jazz, while the Polk offers a bit more rumble for those movie explosions and electronic music drops.

Power Needs

This is important: the Klipsch is more efficient (92dB sensitivity), meaning it can play louder with less power from your amplifier. The Polk needs more juice (86dB sensitivity) to reach the same volume levels. In practical terms:

• Using a 50-watt amplifier, the Klipsch will play noticeably louder
• The Polk benefits more from more powerful amplifiers (75+ watts)

Home Theater Use

Both speakers excel in home theater setups, but they have different strengths:

The Klipsch RP-500M II shines with:

• Clearer dialogue due to the horn tweeter
• Better dynamics for action scenes
• Easier to drive with AV receivers
• Matching center channels readily available

The Polk ES20 offers:

• Smoother sound for long listening sessions
• Better deep bass for movies
• More balanced sound across different content types
• Excellent value in surround setups

Room Considerations

Room size and speaker placement can make or break your listening experience. The Klipsch, being more efficient and dynamic, can energize a small to medium-sized room more easily. The Polk's bigger cabinet and deeper bass extension make it better suited for medium to larger spaces.

Placement tips:

• Keep both at least 8 inches from the back wall
• The Klipsch benefits from toe-in (angling toward the listener)
• The Polk works well with straight-ahead placement
• Both need stable stands for best performance

Value and Build Quality

The price difference ($72) isn't huge, but it's worth considering what you get for your money:

The Klipsch offers:

• Premium finish options
• More sophisticated crossover design
• Traditional audiophile brand cache
• Better resale value typically

The Polk provides:

• More bass extension
• Equally good build quality
• Better value for pure performance
• Modern design aesthetic

Technology Improvements

Both speakers represent significant upgrades over their predecessors:

Klipsch RP-500M II improvements:

• Refined horn design for smoother treble
• New woofer material composition
• Better internal bracing
• Improved crossover components

Polk ES20 advancements:

• Hi-Res certified tweeter
• Enhanced Power Port design
• Better cabinet reinforcement
• Updated crossover design

Making Your Decision

After spending time with both speakers, here's how I'd suggest choosing between them:

Choose the Klipsch RP-500M II if you:

• Love dynamic, engaging sound
• Have a lower-powered amplifier
• Watch lots of movies
• Prefer a more premium brand aesthetic
• Have a smaller room

Go with the Polk ES20 if you:

• Want the best pure value
• Have a powerful amplifier
• Listen to lots of bass-heavy music
• Prefer a more neutral sound
• Have a larger room

Real-World Context

In my experience, both speakers punch above their price points, but in different ways. The Klipsch excels at making music feel alive and present, while the Polk creates a more relaxed, room-filling sound that some might find more natural.

For home theater use, I slightly prefer the Klipsch's ability to handle dynamic swings and clear dialogue, but the Polk's deeper bass makes it a strong contender, especially if you're not planning to add a subwoofer immediately.

Final Thoughts

There's no wrong choice between these speakers - they're both excellent performers that represent different philosophies about how music should sound. The Klipsch RP-500M II gives you that front-row excitement with premium build quality, while the Polk ES20 offers fantastic value with a more laid-back, full-range sound.

Remember, the best speaker is the one that makes your favorite music and movies sound right to you. If possible, try to listen to both before deciding - or buy from a retailer with a good return policy. Your ears will tell you which presentation style you prefer.
