This klipsch reference premiere rp 504c ii review focuses on the physical attributes of the Klipsch RP-504C II Center Channel Speaker. It is a center channel speaker designed for home theater setups.

The unit measures 32.1 inches wide and weighs 36 pounds. It is available in Black or Brown finishes. The design includes a removable magnetic grille. This spec-based look explains how these features translate to actual sound delivery for your listening environment.
What stands out
- 90° x 90° silicone composite hybrid Tractrix horn for clearer dialogue
- LTS titanium diaphragm tweeter that minimizes distortion
- All-new Cerametalllic woofers for efficient sound reproduction
- Tractrix ports for fast air transfer and cleaner bass
- Divided cabinet design with additional bracing to minimize vibrations
Who it fits
Good fit for
You should consider this speaker if you prioritize dialogue clarity in a home theater setup. The large Tractrix horn and LTS tweeter target crisp vocal performance. Its Tractrix ported enclosure helps manage bass without requiring a separate subwoofer for basic low-end support. If you have a wide TV and need a center speaker that fills the space physically, the 32.1-inch width fits that role. The furniture-grade finishes also suit viewers who want the speaker to look good on a stand.
Who should skip it
Skip this option if you need a compact center channel. At 32.1 inches wide and 36 pounds, it is a large unit. It may not fit on smaller TV stands or narrow entertainment centers. The design focuses on high-output performance rather than discrete, low-profile aesthetics. If you prefer a smaller footprint or a different driver configuration, this specific model’s dimensions and weight might be impractical for your space. It is built for presence and power, not for hiding in tight spaces.
Verdict: The Klipsch RP-504C II is a robust center channel speaker built for clear dialogue and efficient bass response. Its large size and specific driver technology make it a strong choice for dedicated home theater rooms.
Key specs for the RP-504C II
Speaker Type: Center channel
This unit is built specifically for the center position in your home theater. It handles dialogue and on-screen action, which requires clarity above all else. You should place this speaker directly below or above your display. Unlike bookshelf speakers that fill a room, this focuses sound forward to your listening seat. It ensures voices remain distinct from background music or effects in your main viewing area.
Tweeter Type: LTS titanium diaphragm
The Linear Travel Suspension design allows the tweeter to move more freely. This reduces distortion when playing high frequencies. You will hear clearer details in vocals and cymbals. Titanium is a rigid material that handles high power well. This spec matters if you want crisp dialogue without harshness. Compare this to standard dome tweeters that may distort at high volumes in your setup.
Enclosure Type: Tractrix ported
The cabinet uses a Tractrix port to manage air movement. This geometry guides sound waves efficiently out of the speaker. You get tighter bass response and less chuffing noise. The ported design helps the speaker produce low frequencies more effectively than sealed boxes. This is useful for home theater movies where you need punchy explosions without muddying the dialogue from the center channel.
Size: 5.25 Inch
The woofer diameter is 5.25 inches. This size offers a balance between bass output and cabinet compactness. You get enough driver surface area for decent low-end extension in a center channel role. It is smaller than floor-standing speakers but larger than tiny satellite drivers. This spec helps you estimate how much bass the unit can produce compared to larger 8-inch or 10-inch center channel alternatives on the market.
Design and Build Quality
According to the listing, the RP-504C II uses furniture-grade materials and finishes. The cabinet features advanced bracing and a divided design to minimize vibrations. This construction aims to keep the speaker stable and clean during high-volume playback. You will find a removable grille that attaches magnetically. This allows you to switch the unit from a showpiece to a discrete component based on your room's aesthetic needs.
The physical dimensions are substantial. The listing specifies a width of 32.1 inches, a height of 6.87 inches, and a length of 15.1 inches. It weighs 36 pounds. You need a sturdy shelf or stand that can support this weight. The Tractrix ported enclosure requires space for air transfer. You should leave a few inches of clearance behind the unit to ensure the ports function correctly and deliver the specified bass response.
You can choose between Black and Brown color options. The Ebony finish is noted in the title. These finishes are designed to blend with home theater furniture. The layout places the LTS titanium diaphragm tweeter and Cerametalllic woofers in a vertical array. This design directs sound horizontally across the seating area. You get a focused soundstage without needing to angle the speaker excessively.
Setup and Everyday Use
Setting up the Klipsch RP-504C II requires attention to its physical dimensions and weight. The listing specifies a width of 32.1 inches, a height of 6.87 inches, and a depth of 15.1 inches. Weighing 36 pounds, the unit is substantial. You will need a sturdy center channel stand or a shelf capable of supporting this mass. The Tractrix ported enclosure design means you must allow space behind the speaker for air transfer. The listing notes that Tractrix ports allow for efficient air movement. Blocking these ports can compromise bass response. You should position the speaker close to your screen, either mounted below or placed on a stand above. The removable magnetic grille allows for an elegant transition. You can attach or detach it easily to change the visual profile. Daily use involves handling dialogue-heavy content. The LTS titanium diaphragm tweeter and ceramic metallic woofers work together to minimize distortion. This setup aims for crisp dialogue clarity. The 90 by 90 degree Tractrix horn guides sound directly to your listening position. You will notice enhanced detail from the vented tweeter housing. The divided cabinet design helps maintain stability during dynamic scenes. You do not need to adjust internal settings. The speaker relies on its passive design and external amplifier or receiver. The available color options include black and brown. You can choose the finish that matches your room’s furniture grade materials. The magnetic grille provides a discrete look when not in use. This setup ensures the speaker integrates seamlessly into your home theater environment without visual clutter.
Things To Check Before Buying
Before you buy, verify your amplifier’s power output matches this center channel’s demands. The RP-504C II uses ceramic metallic woofers and an LTS titanium tweeter, which require clean power to minimize distortion. Check your receiver’s center channel output specifications to ensure adequate drive. This speaker sits alongside other home theater options in our 1 product guide, but its specific Tractrix ported enclosure design sets it apart for dialogue clarity. You should also measure your TV stand or wall mount space against its 32.1-inch width and 36-pound weight. The removable magnetic grille offers aesthetic flexibility, but you must handle it carefully to avoid scratches. Regularly dust the Tractrix horn and tweeter housing with a soft, dry cloth to maintain sound quality. Avoid placing this unit in direct sunlight or near heat sources, as the furniture-grade finishes may degrade over time. Ensure your room acoustics can support its 90 x 90 degree horn coverage for optimal sound dispersion.
Check before you buy
- Verify receiver power output for center channel
- Measure space for 32.1 inch width
