Below we list specific advantages and disadvantages to help decide whether this center-channel speaker fits your system and budget.
What We Like
Horn-loaded LTS tweeter for controlled dispersion
The Klipsch RP-504C uses an LTS Titanium Diaphragm Tweeter mounted in a 90×90 Tractrix Horn to shape high-frequency dispersion and directivity. Horn-loading typically increases vocal presence compared with conventional dome tweeters, which helps voices cut through soundtracks and effects. Home theater listeners and movie lovers focused on dialog clarity benefit most from this design choice.
Cerametallic woofers deliver tight midbass
This Klipsch Center-Channel Speaker (Ebony) is offered at a retail price of $369 and uses Spun Copper Cerametallic Woofers to stiffen the cone. Cerametallic cones resist cone breakup more than paper cones, producing tighter midbass that supports vocal warmth and impact. Buyers matching the center to robust main speakers will notice clearer midrange reproduction for dialogue and effects.
Robust connection options for high-current setups
The RP-504C Center Channel Speaker has single 5-way screw terminals that accept banana plugs or bare wire up to 12 AWG for secure connections. Accepting 12 AWG and banana plugs allows lower resistance speaker runs than spring clips, which is important for long cable runs or high-current AVR outputs. Installers and DIY home theater builders who prefer heavy-gauge wiring or aftermarket cables will appreciate this flexibility.
Tractrix ports reduce port turbulence
The RP-504C Center Channel Speaker incorporates Tractrix ports with inner flares and the same Reference Premiere voicing to reduce turbulence and port noise. Reduced port turbulence lowers audible chuffing at high output compared with straight ports, improving low-frequency cleanliness in dialog passages. Listeners who play movies at moderate-to-high levels will notice fewer port-related artifacts.
Multiple finish choices for room integration
The RP-504C is offered in three finishes – Ebony, Walnut, and Piano Gloss – across a single-speaker cabinet to suit décor choices. Offering three finish options makes matching the center to a living room setup easier than a single-finish model. Consumers who care about aesthetics and speaker system cohesion are the primary beneficiaries.
Passive design works with most AV receivers
The RP-504C is a passive speaker that requires an external amplifier or AV receiver and connects via wired speaker cable up to 12 AWG. Passive operation gives users freedom to choose amplifiers with appropriate power and room correction rather than being locked into integrated electronics. Owners who already have an AVR or plan to upgrade amplification will find this aligns with typical home theater workflows.
Potential Drawbacks
Limited technical documentation for system planning
Data regarding impedance, sensitivity, frequency response, power handling, dimensions, weight, and warranty terms was not available at the time of this review. The absence of these numeric specifications limits accurate system matching, placement planning, and amplifier selection compared with speakers that publish full specs. Buyers who require exact impedance or SPL numbers for AVR configuration and room calibration will be most affected.
Horn loading can emphasize upper mids in some rooms
The Klipsch RP-504C’s 90×90 horn-loaded LTS tweeter can increase upper-mid presence in reflective rooms or when paired with bright mains. That increased presence can make dialog sound forward or slightly bright in untreated rooms, requiring EQ or room treatment to smooth the presentation. Listeners sensitive to pronounced upper mids or those with highly reflective listening spaces are most likely to notice this issue.
Price sits in a competitive mid-to-upper tier
At $369 retail for a single center-channel speaker, the RP-504C competes with other well-reviewed centers that sometimes include published specs or bundled warranty advantages. The price-to-features ratio is reasonable given the LTS tweeter and Cerametallic woofers, but cost-conscious buyers may find comparable performance from rivals at lower price points. Budget-oriented home theater builders and people comparison-shopping with models like the Polk S35 will weigh this carefully.
Performs best when paired with matching Reference Premiere mains
The RP-504C performs optimally when paired with two Reference Premiere main speakers that share voicing and timbral character. Mismatching the center with dissimilar mains can produce uneven tonal balance and imaging, requiring more room correction or EQ. Buyers who do not plan to match their mains to Klipsch Reference Premiere models should consider auditioning the combination before purchase.
Overall, the Klipsch RP-504C center-channel speaker offers clear strengths for dialog clarity, wiring flexibility, and finish options but requires careful system matching and additional specification data for precise planning. Potential buyers should weigh the $369 price against their room acoustics and whether they will pair this unit with matching Reference Premiere mains.

- 12 AWG refers to the maximum recommended speaker-cable thickness the RP-504C's terminals accept; thicker (lower-number) AWG like 12 reduces resistance on longer runs and supports higher current delivery.
- Passive Speaker
- Calling the RP-504C a passive speaker means it has no built-in amplification and must be powered by an external AV receiver or amplifier to produce sound.
- Sensitivity
- Sensitivity (not published here) would tell you how loudly the RP-504C plays for a given amplifier power, and lacking that number makes it harder to predict loudness and amplifier matching.
- Nominal Impedance
- Nominal impedance (also not listed) is the speaker's average electrical load in ohms that your AV receiver must safely drive, so buyers should verify this spec before matching the RP-504C to an amplifier.
