REL T5 Subwoofer: Compact Design, Powerful Bass for Audiophiles

It assumes wide installation freedom and allows for achieving good results with minimal labor costs on the part of the user. However, like any post-processing of the signal, this concept is often criticized by perfectionists for its free attitude to the original material.
The second direction of evolution, promoted by REL, implies the improvement of the canonical circuit of the bass driver due to new materials, more efficient amplifiers, and other components, but without encroaching on the author’s intent. This approach is especially appealing to music lovers, for whom naturalness prevails over showiness, although it creates certain difficulties associated with the correct choice and proper installation of the subwoofer.

An important distinguishing feature of the model is a clear limitation of the frequency range. If other, even good, subwoofers often get into the so-called upper bass – above 100 Hz, then REL T5 works within strictly defined boundaries. The model has a strict design, in a compact closed case with a 20 cm diameter radiator directed to the floor. The long-stroke driver diffuser, made of cellulose, is elastic and at the same time light. The built-in amplifier with a power of 125 W, operating in class AB, is more than enough for it. This rare feature is implemented using a proprietary cable, on one side connected to the terminals of the amplifier (the same ones to which the speakers are connected), and on the other to the subwoofer, where a professional Neutrik Speakon connector is used. But the coin has a reverse side – some bass modules can, due to their wide range, level out the shortcomings of overly compact satellites, and with T5 with them, some gap in the frequency response of the system as a whole is possible. So, to obtain an optimal result, it should be combined with medium and large-sized bookshelf speakers or with any floor-standing speakers. Tiny speakers do not fall into the class of Hi-Fi products that, in terms of quality, correspond to such a perfectionist subwoofer.

One of the key features of all REL products is the ability to produce “fast” bass. While competitors process the signal and introduce additional delay by using drivers with heavy, slow diffusers, the REL subwoofer is capable of producing a pulse that is practically in phase with the main audio range and will not lag behind the main signal. As a result, the bass in the REL T5 is clearly defined, relieved, and free from any overtones. Such support is appropriate not only in cinema, where the use of a low-frequency device is self-evident, but also when playing music of different genres. Among music lovers, there is often an opinion that a triphonic is a compromise system and an active bass module in a good stereo system is an unnecessary detail. But in practice, even massive floor-standing speakers are often unable to provide the proper depth of the low-frequency spectrum, and standard bookshelf speakers are not capable of this in principle. As a result, almost any installation benefits from having such a powerful, yet delicate bass machine.

Even massive floor-standing speakers are often unable to provide the required depth of the low-frequency spectrum, and standard bookshelf speakers are not capable of this at all. As a result, almost any installation benefits from the presence of such a powerful, but at the same time delicate bass machine. The only thing that the owner of the REL T5 should pay the closest attention to is the requirements for the size of the room and the installation of the subwoofer in it. The device is designed for small rooms and only in them can it fully demonstrate all its advantages. It is necessary to be ready to experiment with its location relative to the listeners and the corners of the hall. It is difficult to formulate a single recommendation here, but the difference between the correct and incorrect position of the device is radical.

Fig. 1 shows the frequency response graphs of the REL T5 subwoofer corresponding to three positions of the built-in crossover regulator, namely 120, 80, and 30 Hz. The red curve in the same figure shows the frequency response without correction. The lower cutoff frequency of the module is 27 Hz (at the level of -10 dB). The level of nonlinear distortions increases noticeably with increasing volume in the left part of the working frequency range (Fig. 2). Nevertheless, even at a sound pressure of 96 dB, the introduced harmonics will not be distinguishable in the two upper octaves of the bass region. The average value of this indicator for 90 dB in the specified interval is 1.79%. The cumulative spectrum of signal attenuation reveals a very uniform and fairly rapid decline (Fig. 3).
