About The Klipsch RP-402S Surround Speakers
With its twin Hybrid Tractrix horns and Cerametallic woofers, the RP-402S rear channel speaker is built to effortlessly deliver clear, powerful Klipsch sound and put you right in the middle of the action with exciting cinematic sound.
The Klipsch RP-402S is part of the Reference Premiere range and delivers clear, crisp, dialogue with outstanding bass. It is a medium sized rear-channel speaker and features two 102mm (4") woofers that have Klipsch's distinctive, copper-coloured Cerametallic material. Made with an anodised aluminium, this cone is strong and dent resistant. The anodising process converts its inner and outer surfaces to ceramic. The outcome is a rigid cone with superb damping characteristics that will not flex or resonate at frequencies within the woofer's operating range. The woofers also employ a rubber surround for added durability. When paired with the Tractrix horn-loaded LTS tweeter, it provides the highest speaker efficiency in its class.
With the Reference Premiere Series, Klipsch also gave these woofers a newly developed titanium voice coil former that allows more linear movement for enhanced efficiency, lower distortion, and extended low frequency response. The RP-402S can handle up to 75 Watts RMS and 300 Watts of peak power.
Wide Dispersion Surround Technology (WDST): They deliver precise sonic detail through the careful positioning of two Tractrix Horn loaded titanium-diaphragm tweeters and two 102mm woofers. By aligning the two horns at 90° with respect to each other, along with the two woofers, the RP-402S smoothly covers a 180° horizontal arc, allowing maximum placement flexibility. This unique Wide Dispersion Surround Technology delivers a new dimension of reality and convenience, and produces a smooth, seamless broad distribution of sound, which is the perfect vehicle for every surround format.
A redesigned Tractrix Horn utilises a circular horn throat paired to a square horn mouth to further improve high-frequency response and extension, while enhancing imaging and dynamics. The compressed moulded rubber construction adds high frequency damping to reduce harshness and improve detail. This creates the cleanest, most natural sound possible. These 90° x 90° Hybrid Tractrix Horns provide a wider sweet spot while maintaining controlled directivity of the sound.
Linear Travel Suspension (LTS) Titanium Diaphragm Tweeter: Behind the Tractrix Horn lies a 25mm (1") titanium tweeter with a linear travel suspension for open, natural, sound. The Linear Travel Suspension minimises distortion for enhanced, detailed performance. The new vented tweeter housing reduces standing waves that create unwanted harmonics, resulting in enhanced detail and clarity in high frequency reproduction.
Crossover Network: The Klipsch RP-402S speaker's crossover network is constructed using extremely high-quality components including top-of-the-line internal wiring, polyester film-type capacitors and an air-core inductor to ensure signal purity and proper driver integration. The speaker's enhanced crossover frequency of 1,500Hz offers smooth on-axis and off-axis integration.
Acoustic Suspension MDF Enclosure: The Klipsch RP-402S employs an acoustic suspension enclosure for tight accurate bass. The sealed enclosure features a MDF cabinet finished with a premium wood-grain polymer veneer and a polymer front baffle. The speaker's rigid cabinet offers improved internal cross-bracing to minimise panel vibrations that can colour sound.
Placement: In a typical 5.1 or 7.1 channel system they can be mounted on side or rear walls. It is recommended that they be mounted above the ear height of seated listeners (between 1,500mm and 1,800mm above the floor). They include a single keyhole slot on the back of the cabinet for wall-mounting the speaker without any additional wall-mount bracket but you have to provide the mounting screws because they are not supplied. Weighing just under 6kg each you will need to make sure you mount them securely and use a stud for your screw.
Our Take On The RP-402 Speakers
Klipsch speakers deliver a dynamic and fast sound which is just the thing to impress on movies. But there is another big story to tell and that is the subject of sensitivity or speaker efficiency. Most speakers are about 90dB efficiency and in stereo mode and with a modest approach to the volume control does not present any problem for any good amplifier or home theatre receiver. However as surround sound has increased from 5 speakers up to 9 or even 11, so has the demand on the amplifier or home theatre receiver. Combine more speakers with more volume and average efficiency speakers (say 90dB) and your amplifier will run quite hot and go into clipping - a type of distortion.
One solution is to add an extra power amplifier to hook up the front two or three speakers and leave the receiver to run the centre and rear effects speakers. Another solution is to invest in a speakers like the Klipsch RP-402S. These rear speakers are a quite efficient 93dB which means you can easily run it with half the power of most other speakers and ideally it should be matched with other Klipsch speakers from the Reference Premiere range. One of the better spec receivers will usually do the job beautifully and run nice and 'cool' even at high output levels. Speak with us to get more details or phone in and arrange a demo.
