6. Subwoofers

Subwoofers have evolved into a crucial element, particularly in surround sound configurations. In movie soundtracks, bass even gets its dedicated channel. Over time, 2.1 systems, which consist of two small mid/high-range speakers and a subwoofer, have become increasingly common in computer and hi-fi speakers. This design allows the stereo speakers to remain compact while the bass discreetly emanates from a subwoofer tucked away in a corner. This approach not only reduces costs but also enhances the aesthetic design of these systems. However, there are drawbacks, primarily the need for a clean separation of the frequency range, which isn't always well-executed in cheaper systems.

It's not surprising to find subwoofers integrated into studio monitors, as they take charge of the low frequencies while allowing the near-field monitors to focus on the rest of the frequency spectrum. However, the necessity of a subwoofer largely depends on the music genre. In a typical rock production, a subwoofer might not be needed (and could even be counterproductive), depending on the monitor size. But for bass-heavy music styles, a subwoofer can be indispensable. If you're considering a subwoofer, it's advisable to stick with products from the same manufacturer to ensure compatibility. Always regard monitors and subwoofers as a unified system, ensuring that the subwoofer's crossovers align with the monitors' frequency spectrum. For those who prefer not to rely on the built-in crossover in the subwoofer, an active crossover can be used instead.

Subwoofers, just like the main monitors, need to be positioned optimally. Usually, subwoofers are placed on the floor and should avoid corners or being too close to walls. The distance from the listener should not be too far either. Additionally, the type of flooring in the room can influence the subwoofer's sound. During setup, it's essential to compare the sound to your familiar monitors repeatedly to find the best placement. If you're using a 2.1 monitoring system, it's a good idea to keep your old reference monitors for comparison. This way, you can ensure that your recordings won't lack bass when played on other devices.
