Subsonic Filter

The TRM series uses a Subsonic Filter to prevent the woofer from reproducing inaudible frequencies. Subsonic frequencies (known as infrasonic frequencies) are signals below the normal human hearing range and are generally considered to be below 20Hz. The subsonic filter reduces the energy of these frequencies and restrains the woofer from operating outside its optimum linear excursion. This type of electronic control eliminates the mechanical distortion caused by a woofer traveling beyond its XMAX, improves power handling, increases reliability and improves sonic performance.

THE RESULT: Improved power handling, increased reliability and improved sonic performance.

Phase Control

The Phase Control is used to align the arrival time of the subwoofer's low frequency information with high frequency information pro- duced by additional reference monitors. Aligning both signals will insure that both low and high frequencies arrive at the listening position at the same time. This eliminates the possibility of acousti- cal cancellation and improves the reproduction of transients.

THE RESULT: Eliminates phase cancellation and improves transient response.

The Phase Control can fix up to 270° degrees in phase shift between the outputs of a reference monitor & subwoofer.

Woofer

Santoprene Rubber Surround

Santoprene is a very durable and temperature tolerant material which provides a consistent support necessary for the linear motion of the speaker cone. In addition, the damping capabilities eliminate the transmission of sonic disturbances between the cone and the frame of the speaker. This greatly improves the accuracy of the woofer's low frequency response.

THE RESULT: Improves woofer's low frequency response.

Aluminum Voice Coil Former

The transducer's voice coil former is black anodized aluminum for highly efficient thermal transfer. Another method of producing voice coils is with Kapton® formers. Although this material is very resistant to heat, any heat generated by the transducer is "trapped" on the copper voice coil windings. HAFLER uses aluminum voice coil formers because aluminum acts like a "heat sink" and helps dissipate heat away from the voice coil. This allows winding high temperature copper wire in multiple layers for improved efficiency.

THE RESULT: Improves power handling by efficiently dissipating heat.

TRM12S, TRM10S specifications

The Hafler TRM12S and TRM10S are two standout models in the world of professional studio monitors, designed to meet the demands of sound engineers, audiophiles, and music producers. Known for their exceptional performance and clarity, these monitors are integral to contemporary studio environments.

The TRM12S is equipped with a robust 12-inch low-frequency driver, ensuring deep bass response. This model has been tailored for larger spaces, delivering an impressive output that doesn't compromise on precision. It handles low-end frequencies adeptly, making it ideal for electronic music production, film scoring, and any genre where bass fidelity is paramount. The wide dispersion pattern of the TRM12S allows for a consistent listening experience across different positions in the room.

In contrast, the TRM10S features a slightly smaller 10-inch low-frequency driver, which is perfect for smaller studio setups or for users who prefer a more compact design without sacrificing sound quality. Despite the size difference, the TRM10S still offers profound bass response, making it versatile for various applications, from mixing to casual listening.

Both models utilize Hafler's proprietary technologies, including advanced, high-efficiency amplifiers that provide clean, high output with low distortion. This enables the monitors to produce a wide dynamic range, making it easier for sound engineers to make critical mixing decisions. The integrated DSP (Digital Signal Processing) allows for precise tuning of the audio output, which compensates for any deficiencies in the acoustics of the space.

Another key feature of the TRM series is the adjustable room compensation settings. This functionality empowers users to tailor their monitor settings based on room dimensions and placement, ensuring the optimal playback environment.

Moreover, both the TRM12S and TRM10S are built with durability in mind, featuring rugged enclosures that minimize resonance and vibration, resulting in a clearer audio reproduction. Their sleek design ensures they blend seamlessly into any studio décor, while providing professional-grade sound quality.

Overall, the Hafler TRM12S and TRM10S are designed for professionals seeking reliable, accurate monitors that excel in delivering unparalleled sound fidelity. Their combination of advanced technology, thoughtful features, and solid performance makes them a worthy investment for any serious studio setup.
