INSTALLATION

LOCATION

The acoustic properties and size of the listening environment can drastically influence the SPL (Sound Pressure Level) and f3 (-3dB roll-off) of the subwoofer. However it's important to note that large or small acoustic spaces have little to no effect on the subwoofer cone excursion & box "Q." For the most part, we'll discuss the optimum location for two different installation methods: Studio Installation and Home Theater Installation.

STUDIO INSTALLATIONS

In studio installations, damping material is usually used on the walls and ceilings make the room “acoustically dead.” The main monitors are typically located 3' to 6' from the mixing console and therefore considered a near field (close field) appli- cation. In this type of anechoic environment, the subwoofer will tend to experience minimal "Boundary Loading" effects. For studio installations, HAFLER recommends experimenting with different locations within the studio that minimizes rattles or vibration of other equipment. You can fire the subwoofer downward (FIG. 1) or fire the subwoofer directly facing for- ward (FIG. 2). In either application keep the subwoofer cabinet at least 5" (12.7 cm) away from any wall.

HOME THEATER INSTALLATIONS

Home Theater installations are typically medium sized living rooms or game rooms that have large flat, uncov- ered walls. Acoustics in this type of installation can have a big effect on the SPL and f3 of the subwoofer because the walls are very reflective. The only elements in these installations that acoustically "absorb" sounds are furniture and carpet. Dramatic "Boundary Loading" can be achieved by locating the subwoofer under a table, next to a wall or in a corner (FIG. 4), thus increasing SPL and lowering the f3 of the subwoofer system. Locating the subwoofer in the middle of the room or in a large open area where there are few reflective surfaces will cause a decrease in SPL and an increase in f3. Experiment with different locations in the room to deter- mine which type of bass response works best in your home theater.

TRM12.1, TRM10.1 specifications

The Hafler TRM12.1 and TRM10.1 are professional studio monitors engineered to deliver exceptional sound reproduction within various audio environments. As part of Hafler's prestigious legacy in audio equipment, these monitors cater to audio professionals seeking durability, accuracy, and an impressive performance for mixing, mastering, and high-fidelity playback.

One of the standout features of the TRM12.1 is its 12-inch woofer, which provides a deep and powerful bass response, ensuring that low frequencies are rendered with clarity and precision. This is especially important in genres that emphasize bass, such as electronic music and hip-hop. The TRM10.1, on the other hand, is equipped with a slightly smaller 10-inch woofer, making it an ideal choice for smaller spaces or for users who prefer a more compact solution without sacrificing sound quality.

Both models utilize advanced drive technologies and high-quality components. The tweeter in each speaker is designed for wide dispersion and low distortion, allowing for a balanced high-frequency response that is essential for detailed mixing tasks. This design ensures that the monitors provide a natural and transparent sonic experience, making it easier for audio professionals to make critical listening decisions.

The unique enclosure design of the TRM series minimizes resonance and acoustic interference, which helps to achieve a cleaner and more precise sound stage. The cabinets are constructed from high-density materials to reduce vibration, providing a stable platform for the drivers to perform optimally.

Connectivity is another strong point of the TRM12.1 and TRM10.1. Both monitors feature a variety of input options, including balanced XLR and TRS connectors, making them versatile for integration into different studio setups. This flexibility allows users to connect the monitors to various types of audio interfaces and mixers easily.

User control is facilitated by adjustable rear bass and treble EQ controls, empowering users to tailor the sound to better fit their room acoustics. This feature is particularly useful in situations where room reflections may affect sound quality.

In conclusion, the Hafler TRM12.1 and TRM10.1 studio monitors represent a blend of advanced technology, robust construction, and user-friendly features. Whether in a professional mixing environment or a home studio, these monitors provide the fidelity and reliability that audio professionals depend on to bring their creative visions to life. With their impressive performance and thoughtful design, the TRM series continues to uphold Hafler's tradition of excellence in audio engineering.
