Klipsch RP-504C Review: Is This New Model Any Good?

Your surround sound experience will never be complete without a center channel speaker. As the name suggests, the center channel acts as the central hub and is an integral part of a home theater system. In addition, the speaker helps to balance sound output between the left and right surround speakers to provide you with the ultimate listening experience.

There is no doubt that Klipsch is one of the best manufacturers for center channel speakers that you’ll come across. The Klipsch RP-504C is a big brother of the RP-450C and based on customer reviews, the former has a bigger center presence with a lively Klipsch standard.

Additionally, the RP-504C has refined the Tractrix horn and incorporated a vented tweeter to the design to provide a more accurate high end. Besides, the RP-504C utilizes high-grade components and crossover to deliver significantly better sound quality. Other than that, both speakers share similar technology and have the same sonic signature, and you are unlikely to tell them apart at first glance.

Klipsch RP-504C Center Channel Speaker Review

The Klipsch Reference Premiere RP-504C center channel speaker is designed to complement a wide range of home theater sound systems by providing a powerful center channel sound output. It brings vocals and movie dialogue to life, making it ideal for surround sound setups. This center channel speaker also blends into any home décor and looks very sleek when you place it below the TV.

Most notable features

Klipsch’s signature Cerametallic woofer

Much like its predecessor, the RP-504C is equipped with four 5.25-inch Cerametallic woofers to provide superior bass performance when added to your home theater setup. Although the drivers are less dynamic, they are exceptionally rigid and deliver better midrange clarity.

The lightweight design also ensures maximum efficiency and minimized distortion. The speaker offers a wide frequency response from 58 Hz to 25 kHz for optimal sound reproduction. However, you’ll need to add a powerful amplifier to give your speaker a significant boost.

Tractrix horn-loaded LTS tweeter

If you love your highs bright and crisps, the Klipsch RP-504C may be the ideal choice for you. This speaker feature’s Klipsch exclusive 1-inch Titanium tweeter, paired with a Tractrix hybrid horn to make your highs sparkle and come to life. This horn gives the tweeter a wider dispersion which in turn provides you with a larger sweet spot than traditional-shaped tweeters.

Dramatic design details

Apart from the Tractrix horn, the vented tweeter housing is yet another design feature that makes this center channel speaker stand out. The tweeter is housed in a new vented design which helps to keep unwanted harmonics at bay while delivering enhanced detail and clarity.

In addition, the tweeter utilizes linear travel suspension to ensure that it is not only light but also stiff enough. It also ensures that the tweeter will maintain its shape when the volume is cranked up. Basically, the highs remain clean at any volume level.

Rear Tractrix port

The Klipsch RP-504C features a rear Tractrix port to provide a powerful listening experience even at higher volume levels. The Tractrix geometry is designed to improve the way the port interacts with the air inside and outside of the speaker cabinet.

The design of the port also helps reduce air turbulence and port noise for powerful and cleaner lower frequencies. However, since the port is on the rear, consider placing the speaker away from the walls to facilitate a faster and smooth transfer of air in and out of the cabinet.

Sturdy input terminals

The RP-504C sports single 5-way screw terminals to let you make flexible and strong connections. The terminals accommodate up to 12-gauge speaker wires, and the best thing is that they accept banana plugs. Furthermore, the terminals come in brilliant color-coding for easy identification and to facilitate easy setup and connection.

All-MDF casing

You’ll also like the fact that the RP-504C is enclosed in an all-MDF cabinet, a design that helps to reduce sonic resonance. The unit comes in an elegant Ebony vinyl finish, but piano gloss and walnut vinyl finishes are also available.

The best part yet, the baffles are scratch-resistant for improved durability. Other design details include cast aluminum feet, copper trim, and a laser-etched Klipsch logo to give the speaker a contemporary and premium look.

What we like

  • Excellent addition to any Klipsch reference home theater system
  • It awakes the entire center channel spectrum up
  • Modern cabinet design
  • Superb port technology
  • The speaker grille is not only removable but also pretty strong
  • Movie dialogue is crystal clear, and there is no harshness to it
  • It matches several Klipsch RP speakers

What we don’t like

  • Lacks bi-amp capability
  • Weak midbass
  • Way expensive than RP-405C, considering that they are almost similar

Our Final Take!

Klipsch’s center channel speakers have been at the top of their game for quite some time, and the RP-504C is no exception. We were blown away by how powerful and dynamic the Klipsch RP-504C is, so you can finally enjoy your movies and pretty much anything you throw at it.

Although it is an amazing center channel speaker, it does not replace right and left speakers in a stereo or surround sound setup. If you looking to replace or build a complete sound system, you’ll need to spend more on good floor standers/bookshelf speakers. You may also want to pair your speakers with an AV receiver with the desired number of channels and the controls you like.

Ultimately the Klipsch RP-504C will provide value for your hard-earned cash and is one of the best investments for your home theater setup. We hope this Klipsch rp-504c review is informative. If there’s anything we may have left out, feel free to share it in the comments section.
