Bass Drivers

The woofer utilizes a low mass hybrid Aluminum/Rohacell®/Kevlar® cone with an over hung voice coil. Even under massive dynamic demand, the driver retains linearity and low distortion. A three-part high intensity neodymium magnet is used with a main magnet, plus rear and forward magnets placed to ensure linearity, reduce stray magnetic energy and provide intense field strength in the voice coil gap. Dual Faraday rings on the pole piece minimize unwanted inductance, enhance heat dissipation and minimize dynamic compression.

The metal cone of the woofer is damped with a composite Rohacel and Kevlar lay- ers which minimices ringing and maintains low mass, eliminating breakup and other

distortion products. As is the case with the midrange driver, the surround uses a flat-sided shape which keeps surround-produced output to a minimum and preserves phase response. The cast aluminum frame assures maxi-

mum heat transfer without any reflection of the back wave of the driver that would otherwise alter the sound. An inverted half-roll low density foam rubber surround completes the clean

appearance.

In the P-38F and the P-37F he woofers see differing pass bands. This preserves con- sistent dispersion through the critical woofer to midrange transition region and has a positive impact on off axis performance and stereo imaging. This upper woofer covers the entire range from 30 Hz to 500 Hz, where it crosses over to the midrange driver, while the two lower woofers cover only the low and mid-bass. This “tapered-array”

design delivers full bass impact, plus a graceful transition between driver groups in both tonal accuracy and dispersion.

Midrange - “The midrange is where we live” Paul W. Klipsch

The inverted dome midrange driver operates from 500 Hz to 3.5 kHz and is a unique design, not found on any previous Klipsch product.

The driver sensitivity of 106 dB allows minimal excursion at normal playback volume. As cone excursion reduces, so does distortion. The 4.5-inch aluminum dome is driven by 3 high temperature N35H neodymium magnets, ensuring linearity under a range of listening volumes. The pole piece is topped by a copper cap, whose purpose is to minimize unwanted inductive components. The surround has half the density of the material typically used and thus offers reduced mass. Unlike most designs, this midrange driver delivers much more output from the dome and less

from the surround. As a surround is always in motion and always changing shape, output from its surface is high in distortion—minimizing surround surface area is another means to reducing overall distortion.

The midrange unit is housed in its own magnetically-shielded sealed enclosure, which isolates the driver from acoustic energy generated by the woofers. Every effort has been made to ensure great accuracy, as well as long-term durability from this unique driver.

The Klipsch P-17B is a compact bookshelf speaker that packs a punch. With its Tractrix Horn-loaded tweeter, it delivers crisp and detailed high frequencies, making it a perfect choice for music lovers. Its 5.25-inch woofer provides deep bass response, ensuring that every note is heard. The speaker's minimalist design, combined with premium materials, ensures it blends seamlessly into any setting.

Moving up, the P-38F is a powerful floorstanding speaker that features dual 8-inch woofers, delivering enhanced bass performance and dynamic range. The P-38F utilizes Klipsch’s exclusive LTS tweeter, which minimizes distortion and ensures clear, detailed sound reproduction. Additionally, the Tractrix port design reduces turbulence, allowing for tight and accurate bass responses, making it ideal for home theater setups.

The P-37F also belongs to the floorstanding category, offering a slightly different sound profile. Its three-way design incorporates a 6.5-inch midrange driver for improved vocal clarity and a seamless transition between the highs and lows. The combination of dual 8-inch woofers and a Tractrix-loaded tweeter results in a wide soundstage and impressive imaging, making it an excellent choice for both music and movies.

For center channel performance, the P-27C is a standout. It features dual 5.25-inch woofers, providing powerful dialogue intelligibility and clarity in movie soundtracks. The Tractrix Horn technology enhances high-frequency performance, ensuring speech remains clear and engaging, which is crucial for an immersive home theater experience.

Lastly, the P-27S serves as a satellite speaker ideal for surround sound setups. Its compact design, featuring a 4-inch woofer and a Tractrix Horn tweeter, delivers remarkable sound quality without taking up much space. Perfect for mounting on walls or placing on shelves, the P-27S completes a multi-channel system with rich, detailed audio across all frequencies.

Overall, Klipsch's P series speakers, including the P-17B, P-38F, P-37F, P-27C, and P-27S, combine innovative technologies and aesthetic design to create a rich audio experience tailored for any environment, making them an excellent choice for anyone looking to elevate their sound.
