When it comes to Klipsch subwoofers, opinions are usually pretty divided. In the realm of Klipsch subwoofers, a significant number of enthusiasts reside at opposite ends of the spectrum where you either appreciate the sound they produce at their price point, or you feel that they don't reach low enough frequencies.


No matter which side of the debate you find yourself on, Klipsch has launched a new line of subwoofers designed to cater to a much wider audience. The latest Reference Premier line has been meticulously crafted to address the concerns and preferences of both enthusiasts and skeptics. So let’s dive in and see what the new RP-1400SW has to offer.

Specifications

The RP-1400SW, as its name suggests, features a substantial front-firing 14" Cerametallic woofer as its centerpiece. This newly designed Cerametallic woofer incorporates ultra-long throw transducers, ensuring exceptional performance and a strong low-frequency experience. The woofer's rigid construction minimizes cone breakup and distortion, allowing for precise and accurate reproduction of low frequencies.


This subwoofer features a brand new 500-watt RMS (1,000-watt peak) Class D amplifier with a max SPL of 124db, providing ample power to enhance your audio experience. With a frequency response ranging from 16Hz to 141Hz (±3dB), it covers a wide range of low frequencies, delivering a solid bass performance.

Klipsch RP-1400SW Rear

At the rear of the subwoofer, you'll find dual RCA ports that allow you to connect a stereo output or utilize the conventional line-out LFE port typically found on amplifiers and receivers. Like other Klipsch subwoofers, the RP-1400SW features a Gain and a Low Pass knob, allowing you to adjust the output to your liking. The dials on these knobs have been enlarged and feature markings engraved into the sides of the knobs to make changing the setting easier without having to move the speaker away from the wall.

Positioned next to these controls is a phase switch that can be set to either 0 or 180 degrees. The subwoofer also includes an AC input and a power/auto/standby switch. There's also a WA-2 port that provides compatibility with the optional wireless kit, giving you more flexibility in your setup.


Design

The RP-1400SW is a massive subwoofer that demands attention with its substantial size. Measuring approximately 20 inches wide x 21.34 inches tall x 25.67 inches deep and weighing 83.7 lbs, it is a noticeable presence in any room.

Klipsch RP-1400SW Grille

The new RP line features a double thick cloth grille, rounded corners, steel grille posts, and shock-absorbing rubber feet. These design elements not only add a touch of sophistication but also serve a functional purpose. The grille and rounded corners contribute to a sleek and stylish appearance, while the steel grille posts and rubber feet provide stability and help minimize vibrations.


The subwoofer, like the reference premiere speaker lineup, is finished in a scratch-resistant ebony vinyl, which gives it a refined look resembling real wood. Looking at the front of the subwoofer, it’s impossible to miss the prominent slot-shaped port positioned at the bottom. Klipsch refers to this design as an Aerofoil, which spans the entire width of the subwoofer. The purpose of this Aerofoil is to minimize port noise, ensuring that low frequencies remain clear and undistorted.

Setup

Positioned it in the front left corner of my room, I slightly angled the subwoofer towards the listening position for optimal sound dispersion. I utilized the LFE input to establish a seamless connection between the RP-1400SW on both a Trinnov Altitude16 and a Denon 4800H. I also made sure that the Low-Pass knob was set to LFE and set the gain to roughly 7.

FAQ

How do I hook up my Klipsch subwoofer?

To establish the connection between the Subwoofer and the AV receiver, utilize an RCA cable known as a Subwoofer cable. This cable should be connected from the Subwoofer output on the receiver to the line input on the Subwoofer. Klipsch subwoofers offer multiple connection options, including utilizing the LFE channel, the white RCA connection, or connecting in a Stereo pair by utilizing both the white and red RCA connections.


What size subwoofer is best for bass?

The size of a subwoofer alone does not determine its bass performance. While larger subwoofers generally have the potential for deeper and more powerful bass due to their ability to move more air, factors such as driver quality, amplifier power, and enclosure design also significantly impact bass reproduction. It's important to consider your specific needs, room size, and budget when selecting a subwoofer, as a well-designed and properly calibrated subwoofer of any size can deliver excellent bass performance.


Are 2 subwoofers always better than 1?

Using dual subwoofers significantly boosts the overall capacity of the system, resulting in increased dynamic range, reduced compression in output, lower distortion, and minimized risk of overdrive artifacts. In essence, employing dual subwoofers ensures cleaner and more precise bass reproduction, particularly when pushing the system to its limits.
