„Design

NHT loudspeakers are designed to deliver refined, musical sound from attractive and affordable packages. Our efforts are guided by the study of human hearing and are optimized for real-world use. Every NHT speaker undergoes rigorous testing and quality control at the factory to ensure you years of listening pleasure.

The CS-6.1 Ci and CS-6.3 Ci are designed to deliver the sonics and value of NHT’s acclaimed freestanding speakers, while offering the invisibility of in-ceiling installation. The drive units are custom-designed to achieve a level of performance not normally associated with in-ceiling speakers, while its intuitive mounting system makes it ideal for new or existing construction. The CS-6.1 Ci features one coaxially mounted tweeter, while the CS-6.3 Ci employs NHT’s innovative three- tweeter array for more even sound dispersion to a wider range of listening areas.

Caution: The CS-6.1 Ci and CS-6.3 Ci should be installed by an experienced and licensed custom installation profes- sional. Be sure that the installer possesses sufficient skill, the proper tools, knowledge of local fire and building codes, and a familiarity with the structure of the building (especially wall and/or ceiling materials, layouts, electrical and plumbing lines, etc.).

„Placement

The CS-6.1 Ci and CS-6.3 Ci are designed for in-ceiling installation between standard 2” wood joists. Their moisture-resis- tant drive units allow them to be installed in moisture-prone interior environments such as bathrooms, indoor swimming pool and sauna rooms. Outdoor use is not recommended.

Spend some time considering placement prior to installing the speakers. Once they are installed, they are permanent, so their location should be selected carefully. When possible, locate the speakers at least 3 feet from adjacent side walls. The speakers should be mounted on a flat surface to ensure a good seal between the baffle and the mounting surface. When possible, position the speakers so that they are equidistant from the most likely listening area. If the CS-6.1 Ci or

NHT, a well-known name in the audio industry, has developed the CS-6.1 Ci and CS-6.3 Ci, two exceptional loudspeakers that are designed to deliver high-quality sound performance for audiophiles and casual listeners alike. These models exhibit a blend of advanced technology, elegant design, and impressive features, making them ideal for home theater systems or stereo setups.

The CS-6.1 Ci is a compact bookshelf speaker that strikes a balance between size and audio excellence. It features a 6.5-inch woofer and a 1-inch silk dome tweeter, which work harmoniously to produce a broad frequency range with crystal-clear highs and powerful lows. The CS-6.3 Ci, on the other hand, is a floor-standing speaker that enhances the listening experience with its dual 6.5-inch woofers. This configuration allows the CS-6.3 Ci to achieve a deeper and more impactful bass response, making it a perfect choice for those who crave a more immersive audio experience.

One of the standout characteristics of both models is their use of advanced crossover technology. The speakers come equipped with precision-engineered crossovers that ensure a seamless transition between the woofer and tweeter, thus minimizing distortion and maximizing clarity. This results in a coherent soundstage, where every instrument and vocal is accurately represented, allowing listeners to fully appreciate their favorite music or movie soundtracks.

Another notable feature is the cabinet design. NHT has crafted the CS-6.1 Ci and CS-6.3 Ci with high-quality materials that not only enhance durability but also reduce resonance. The sleek finish and understated aesthetic allow these speakers to blend seamlessly into any decor while making a subtle statement about audio sophistication.

In terms of connectivity, both models are designed with standard binding posts, providing compatibility with a wide range of audio systems. Their sensitivity ratings make them versatile, allowing them to be paired with various amplifiers without compromising sound quality.
