Choosing Between Klipsch's Popular Bookshelf Speakers: A Detailed Comparison

When it comes to high-quality bookshelf speakers, Klipsch's Reference Premiere line stands out for delivering impressive sound quality at reasonable prices. Let's compare two popular models - the newer RP-500M II ($349) and the RP-600M ($649) - to help you make the right choice for your setup.

Understanding Bookshelf Speakers

Before diving into specifics, let's understand what makes bookshelf speakers special. Unlike floor-standing speakers, these compact units are designed to provide excellent sound quality while saving space. They're called "bookshelf" speakers because they can literally fit on a bookshelf, though they often perform best on dedicated stands.

The Technology Behind Both Speakers

Both models share Klipsch's signature technologies:

Horn-Loaded Tweeters

Both speakers use Klipsch's Tractrix horn design, which works like a megaphone for high frequencies. This horn-loading (a way of acoustically amplifying sound) makes the speakers more efficient, meaning they can play louder with less power from your amplifier.

Cerametallic Woofers

Both use Klipsch's distinctive copper-colored woofers made from ceramic-coated aluminum. This material is lightweight but rigid, helping reduce distortion when the speaker cone moves back and forth to create sound.

Key Differences That Matter

Size and Power

The RP-600M uses a larger 6.5-inch woofer compared to the RP-500M II's 5.25-inch driver. This size difference matters in three ways:

1. Bass Response: The RP-600M reaches slightly lower bass notes (45Hz vs 50Hz)
2. Volume Capability: The larger speaker can play louder without strain
3. Room Size Requirements: The RP-600M needs more space to sound its best

Sound Character

Having tested both models, I've noticed some interesting differences:

• The RP-500M II offers more precise imaging (ability to locate instruments in space)
• The RP-600M provides a fuller, more room-filling sound
• Both handle dynamic swings well, but the RP-600M has a slight edge for movie explosions

Technology Updates

The RP-500M II, being newer, incorporates some recent improvements:

• Updated crossover design for smoother integration between drivers
• Refined horn design for wider sound dispersion
• Improved cabinet bracing for less resonance

Real-World Performance

Music Listening

Both speakers excel with music, but they have different strengths:

RP-500M II:

• More precise positioning of instruments
• Excellent for intimate jazz and acoustic music
• Better for near-field listening (sitting close to speakers)

RP-600M:

• Fuller sound with rock and orchestral music
• More impact on bass-heavy tracks
• Better for filling larger spaces

Home Theater Use

Both speakers work well in home theater setups, but there are considerations:

• The RP-600M's higher sensitivity (96dB vs 92dB) means it can play louder with less power
• The RP-500M II's smaller size makes it easier to position in multi-speaker setups
• Both integrate well with subwoofers, which is important for home theater

Value Proposition

The RP-500M II at $349 represents excellent value, offering:

• Most of the RP-600M's performance at nearly half the price
• Easier placement options due to smaller size
• Latest technology updates

The RP-600M at $649 justifies its higher price with:

• More powerful bass response
• Higher volume capability
• Better performance in larger rooms

Room Considerations

Your room size and shape significantly impact which speaker might work better:

Small Rooms (<200 sq ft):

• RP-500M II is often the better choice
• Easier to position
• Less likely to overwhelm the space

Large Rooms (>200 sq ft):

• RP-600M's larger driver helps fill the space
• Higher sensitivity helps maintain impact at distance
• Fuller sound better suits larger spaces

Making Your Decision

Consider these factors in order of importance:

1. Room Size
   • Small room → RP-500M II
2. Large room → RP-600M
3. Budget
   • If budget is tight, the RP-500M II offers tremendous value
4. If you can afford either, let room size guide your choice
5. Listening Preferences
   • Critical listening → RP-500M II
6. Movie and dynamic music → RP-600M
7. Amplifier Compatibility
   • Lower-powered amps (<50W) → RP-600M (more efficient)
8. Modern receivers → Either model works well

Personal Experience and Recommendations

After extensive testing, I've found the RP-500M II to be the more versatile choice for most users. It's easier to position, works well in more rooms, and offers excellent value. However, in my larger listening room (300 sq ft), the RP-600M's additional capability is noticeable and appreciated.

For home theater use, I slightly prefer the RP-600M when budget allows, as its additional dynamic capability helps with movie soundtracks. However, the RP-500M II paired with a good subwoofer comes very close to matching this performance.

Final Thoughts

Both speakers represent excellent value in their price ranges. The RP-500M II is the safer choice for most users, offering modern technology and excellent performance at a more accessible price point. The RP-600M remains compelling for those with larger rooms or specific needs for its additional capabilities.

Remember, speaker choice is somewhat personal, and if possible, trying to hear both models in your space would be ideal. However, both models uphold Klipsch's reputation for dynamic, engaging sound, and either will serve well in the right environment.
