About the Klipsch Reference Premiere RP-400C

Classic Klipsch sound

The RP-400C might be the smallest center channel in the new Klipsch Reference Premiere lineup. But this dynamic speaker delivers accurate dialogue and engaging center-stage sound effects thanks to two 4" spun-copper woofers and Klipsch's signature 1" horn-loaded tweeter. It's an excellent choice for a Klipsch surround sound system in a small- to medium-sized room.

Use the RP-400C center channel as part of a high-impact Klipsch home theater system.

Hybrid horn technology for dynamic performance

Horn technology is one of Klipsch's long-standing hallmarks. Flared openings in the speaker cabinet project sound waves toward your listening area and prevent them from simply spilling out in all directions. This design reduces reflections that can color the sound, and boosts dynamics and efficiency for powerful, "front row" sound that remains crystal-clear at all volume levels.

Klipsch's Tractrix® horn features a circular throat around an advanced titanium diaphragm tweeter that transitions into a square 90º x 90º mouth. This unique shape provides a cleaner, more efficient transition of sound waves into your listening space. The result is a wide listening "sweet spot" with precise placement of instruments and vocals. 

A horn that enhances bass, too

Take a look at the back of the RP-400C and you'll find that instead of the conventional round port tube found on many speakers, Klipsch uses a Tractrix horn-shaped opening for smoother, more efficient airflow in and out of the cabinet. The resulting decrease in air turbulence makes for cleaner, more powerful bass with reduced port noise and low-frequency distortion.

Because this speaker is rear-ported, I recommend pulling it away from your wall to give it room to "breathe."

Product Research


1" Horn-Loaded Tweeter: The Klipsch RP-400C center-channel loudspeaker features a 1" Titanium LTS Vented Tweeter with a Hybrid Tractrix Horn for exceptional high frequency response, detail, and dispersion. Klipsch proprietary Tractrix horn-loaded technology ensures high-frequency energy of the RP-400C center-channel speakers are aimed directly at the listener and reduces unwanted, artificial reverb caused by indirect sound bouncing off walls - meaning you experience the most clear, detailed, lifelike sound possible.

  • Titanium LTS Vented Tweeter: The titanium tweeter diaphragm's light weight yet rigid composition exceeds the performance of aluminum, polymer or silk tweeters. A vented tweeter design reduces standing waves behind the tweeter diaphragm for a smoother high frequency reproduction. Klipsch award-winning Linear Travel Suspension technology leverages a piston motion of the titanium diaphragm that lowers distortion and delivers real-to-life sound. A ceramic magnet housing provides premium performance,
  • Hybrid Tractrix Horn Technology: This redesigned 90°x90° Hybrid Tractrix Horn utilizes a circular horn throat paired to a square horn mouth to further improve high-frequency response and extension, while enhancing imaging and dynamics. The Hybrid Tractrix Horn's compressed molded silicon face adds high frequency damping to reduce harshness and horn resonance for a smoother frequency response with improved detail - creating a clean and natural sound. Klipsch also utilizes computer modeled phase plugs that act as a mechanical filter to further ensure a smooth, flat frequency response while protecting the tweeter from damage.

Dual 4" Cerametallic Woofers: The RP-400C center-channel loudspeaker utilizes two 4" Klipsch Proprietary Cerametallic woofers. Cerametallic consists of extremely light, rigid materials that can hold shape while being able to deliver lower frequencies with maximum efficiency. The Klipsch Cerametallic cone is matted to a dual-layer, copper-wound voice coil for exceptional conductivity. The 4" woofers are housed in a non-resonating, stamped-steel basket that's secured to a large magnet motor for exceptional efficiency and low distortion.

Rear Tractrix Port: The rear Tractrix port of the RP-400C center-channel loudspeaker is perfectly matched to the cabinet and woofer, creating ideal airflow with minimal distortion and turbulence even at the lowest frequencies. Klipsch Tractrix ports have custom designed inner flares that help reduce air turbulence entering the port. Less turbulent air helps reduce port noise for cleaner, more powerful bass.

MDF Cabinet: The Klipsch RP-400C center-channel speaker features a MDF cabinet with a scratch-resistant, textured wood grain vinyl that seamlessly integrates into almost any room or decor. The enclosure's reinforced MDF construction reduces cabinet vibration for less audible coloration and improved sonic accuracy. The MDF enclosure also features a satin painted baffle with a scratch resistant design for an elegant look without the grille.

Acoustically Transparent Grille: The Klipsch RP-400C center-channel loudspeaker comes with a removable, black cloth grille that is magnetic and acoustically transparent. This strong magnetic grille provides protection and a sleek aesthetic look to compliment your home's decor.

Binding Posts: The Klipsch Reference Premiere series center-channel speaker is fitted with sturdy  binding posts to ensure a secure connection to many types of cable and connectors. The binding post terminals will accept banana plugs (single only), pin-connectors, spade-lugs and bare wire (up to 10AWG). Two plastic caps will need to be removed to use banana plugs.

Placement & Mounting Options: The center channel speaker is designed to place dialog and primary sounds so that they appear to come from the TV or projector screen. The speaker should therefore be centered and placed as close to the screen as possible, preferably directly on top of or below the screen.

  • Rubber Feet: The center channel speaker comes with four self-adhesive rubber feet to secure the speaker in place and prevent any damage to your stand's or shelf's surface. The rubber feet add approximately 0.125" to the height of each speaker.
  • Adjustable Angle: If the center speaker is well above or below the ear height level of seated listeners, you can improve performance by angling the center channel slightly to compensate. Included with the speaker is an adjustable foot that you can screw into one of the two threaded inserts on the bottom of the cabinet. To tilt the speaker down, install the foot in the insert near the back of the cabinet; to tilt the speaker up, install the foot in the insert near the front of the cabinet.
Note: There is no included bracket, keyhole slot, or threaded insert to wall-mount the speaker.

Reference Premiere Series: The Klipsch Reference Premiere series utilizes a redesigned hybrid 90°x90° Tractrix Horn, a vented LTS titanium tweeter, Cerametallic woofer construction, and Tractrix geometry port technology for sound that will envelope you and blow you away. The Reference Premiere series by Klipsch consists of a variety of floorstanding, bookshelf, center, and surround speakers (all sold separately). Click on the Accessories Tab to find more Reference Premiere series speakers for your home system.

Optional Powered Sub: For bigger & deeper bass response, pair the Klipsch Reference Premiere series loudspeaker with one of Klipsch's powered subwoofers (sold separately - click on Accessories Tab).

Which would be a better match for front speakers with this center channel? R-51M bookshelf or RP-4000F floor?
[ Terru  Jan 27, 2022 ]
4 answers
I have both set of speakers synced to a Klipsch R28F in the front, using a R12SW for the heavy hitting sounds.
[ Alonza  Jan 27, 2022 ]
In my opinion the RP-4000F will be a perfect match. The Reference Premiere line produces a much better overall sound compared to the Reference line also.
[ Andrew  Jan 27, 2022 ]
I would choose the RP-4000F.
[ JOHN  Jan 27, 2022 ]
I'd stick to prefix RP. Either 5000 or 6000
[ Leonard  Jan 27, 2022 ]
is a 20 x 30 room to big?
[ Bradley  Dec 01, 2021 ]
2 answers
It should be fine.
[ JOHN  Dec 01, 2021 ]
I suppose it depends on the rest of the speakers in your system. Our theater isn't quite that big, but the center channel fills it pretty well. Hope that helps.
[ Dave  Dec 01, 2021 ]
it's ok for a Yamaha RX V6 7.2 home cinema ?
[ Abourg666  Jul 20, 2021 ]

Depends on your room size. I use it on my bedroom with a Denon receiver. The center dialog sounds crisp and clear. Remember it is a small center channel speaker but it won't disappoint you.
[ JULIO  Jul 24, 2021 ]
Perfect! This is a great center speaker!
[ STEVE  Jul 21, 2021 ]
It works great with my Denon 7.2 Dolby Atmos/ DTS system
[ Richard  Jul 21, 2021 ]
can I pair this with the Reference Series 5-1/4" 340-Watt Passive 2-Way Bookshelf Speakers?
[ ecper  Oct 31, 2020 ]
2 answers
Absolutely! This is an amazing center speaker and would complement the bookshelf speakers. Might struggle at 340 watts!
[ STEVE  Oct 31, 2020 ]
Yes , For Sure! This lil guy has plenty of Bean's to keep up and handle that. Have mine paired w Matching 6.5's For my Front channel and 5-1/4's in the Rear and the setup is Awesome!!
[ SUNEIL  Oct 31, 2020 ]
Can this unit be wall mounted? Or will the sound be muffled?
[ ericmax  Oct 27, 2020 ]
2 answers
I'm not sure. I didn't mount mine to the wall.
[ Joshua  Oct 28, 2020 ]
Yes it can be wall mounted. I have mine on a shelf against the wall and it sounds excellent.
[ Ghost  Oct 27, 2020 ]
I just purchased a rp400-c and it sounds muffled. Any suggestions for troubleshooting?
[ Brian  Sep 27, 2020 ]

May just need to let get broken in
[ Ghost  Oct 27, 2020 ]
I bought one and don't have that concern , try either reconnect speakers wires or maybe replace them.

When I bought mine, I had to check all of the settings in my receiver. I only have a three-speaker setup, with this speaker as the center and then bookshelf speakers for left and right. My receiver was defaulting to surround sound, which was not right for my setup. I also check equalizers and other settings to optimize the sound. I'd recommend looking through all your receiver settings and see what you can play with.
[ Joshua  Oct 01, 2020 ]
I guess the first thing I would check is the polarity and make sure it is connected right. Positive to positive. The second thing is to make sure you have the center channel connect to the correct speaker on your stereo amp. There are also adjustments you can make on your stereo amp to adjust you speaker levels. I hope this helps Regards, Joe
[ JOSEPH F  Sep 27, 2020 ]
When you say pulled the Center speaker away from the wall to give it breathing space, how much space are you talking about?
[ Robert  Sep 21, 2020 ]
3 answers
It will vary with each room and setup. Move it in the available space to achieve the best sound.
[ JOHN  Oct 13, 2020 ]
my front speakers, left and right, are a foot away from the wall. i follow the same rule for the center channel. they all line up perfectly.
[ JULIO  Oct 13, 2020 ]
The speaker front is 24" from the wall
[ STEPHEN J  Oct 13, 2020 ]
I have a Yamaha receiver that puts out 115 watts per channel. Could this center speaker handle it or should I go with a higher quality one?
[ Chris K  Jun 29, 2019 ]
3 answers
1. Is that 115 watts PEAK or RMS? Many mfgrs use PEAK wattage, or what the signal is at the maximum for less than a millisecond, which is misleading in my opinion. The RMS, or effective wattage, is the normal standard for many higher end companies, like Klipsch. If you're at 115w peak, then multiply by .707 for RMS. 2. The RP-400C is rated 75w RMS so, if you're at 115w PEAK, it is actually about 81w RMS. If I sat in front of my Marshall stack turned up half way in my living room, I would lose my hearing. I think you'll be okay.
[ CLAUDE  Jul 04, 2019 ]
I don't know if you can give it full power but I will say it handles my onkyo with ease
[ TIMOTHY C  Jul 04, 2019 ]
I really cant answer that question. All I can tell you that my Klipsch speaker is hooked up to a Yamaha receiver and seems to work very well. Unfortunately I do know the outut of the Yamaha receiver
