Four-Woofer Arsenal Helps Klipsch RP-404C Center-Channel Loudspeaker Play with Weight, Power, Presence, and Depth: Home-Theater Centerpiece Sounds as Sharp as It Looks
Just because you may have space constraints doesn't mean you need to sacrifice on sound. Outfitted with an arsenal of four woofers and yet measuring an economical 5.7 x 26 x 13 inches (HWD), the Klipsch RP-404C center-channel loudspeaker plays with pleasing punch, dynamics, transparency, and weight. Voiced to seamlessly match with any model in the Reference Premiere line, and claiming an easy-to-drive 97dB sensitivity, RP-404C serves as a home-theater specialist.
Engineered for stellar performance, each of the quartet of four-inch spun-copper Cerametallic drivers are matted to a dual-layer, copper-wound voice coil for exceptional conductivity. All arrive housed in a non-resonating, stamped-steel basket secured to a large magnet motor for stellar efficiency and low distortion. RP-404C also boasts a rear Tractrix port that provides airflow with minimized turbulence even during complex low-end passages.
True to Klipsch tradition, RP-404C leverages the company's signature horn technology in the form of a one-inch titanium Linear Travel Suspension (LTS) vented tweeter with hybrid Tractrix horn. The architecture ensures the high-frequency energy aims directly toward you and reduces unwanted reverb caused by indirect sound bouncing off walls. In addition, the compressed molded silicon face matted to the 90° x 90° Tractrix horn reduces resonance for smooth frequency response. Computer-modeled phase plugs further act as astute mechanical filters.
Befitting the centerpiece of any surround setup, RP-404C looks spectacular. Satin-painted, scratch-resistant baffles help showcase the ebony or walnut finish. Magnetically attached grilles and a five-year manufacturer warranty round out a design deserving of the Reference Premiere badge. 100% Music Direct Guaranteed.
"If you're looking for speakers that can deliver the highs and lows of a modern blockbuster without requiring a shed-load of power, this particular system makes perfect sense – and it's not insanely priced, either."
– Steve Withers, Home Cinema Choice, Best Buy Award
90° x 90° Silicon Composite Hybrid Tractrix Horn
Horn loading maximizes efficiently and increases detail while focusing high frequencies towards the listening area. Proprietary Tractrix® geometry provides the most efficient transfer of high frequency waves into the listening area. The phase plug and compressed molded silicon face ensure smooth frequency response. When combined, clean, natural sound is created.
Linear Travel Suspension (LTS) Titanium Tweeter
The exclusive Linear Travel Suspension minimizes distortion for enhanced, detailed performance. LTS tweeters are a hallmark of previous Reference lines, making it a core component of some of the best speakers in the world.
Vented Tweeter Design
The new vented tweeter housing reduces standing waves that create unwanted harmonics, resulting in enhanced detail and clarity in high-frequency reproduction.
Spun Copper Cerametallic Woofers
A signature feature on the Reference Premiere series, Cerametallic™ woofers are exceptionally rigid and lightweight for minimal distortion and maximum efficiency. When paired with the Tractrix horn-loaded LTS tweeter, it provides the highest speaker efficiency in its class.
Utilizing Tractrix geometry, the Reference Premiere ports allow for the most efficient, fastest air transfer from the cabinet, which reduces port noise for punchier low 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.
Robust Input Terminals
Single five-way screw terminals accept banana plugs or bare wire up to 12-gauge for flexible, lasting connections while the vibrant color coding provides easy setup and connection.
Ebony and walnut models boast satin painted baffles with a scratch-resistant finish. Copper anodized trim rings, cast aluminum feet, satin painted baffles and a laser-etched logo treatment give the Reference Premiere II series a modern, premium look.
