The secret of lively sound: The subwoofer
Music is all about rhythm, emotion and power! Low frequencies play a key role in bringing relief and depth to the sound. But how do you integrate them into your audio system? That's where the subwoofer comes in.
Why a subwoofer?
Modern loudspeakers are designed to deliver excellent sound clarity and greater precision in the mid and high frequencies. However, their compact size often limits the reproduction of deep bass.
In the past, loudspeakers incorporated large diaphragms that naturally amplified bass, but this could affect the perception of details and the sound positioning of instruments.
Today, the optimal solution is to add a subwoofer, a speaker dedicated to low frequencies, which frees up the main speakers for a more balanced, immersive sound reproduction.
The 2 types of subwoofer
There are two types of subwoofers:
- Passive: draws its power from the main speakers, but lacks power and flexibility. Some dedicated amplifiers do exist, but they are rare and mainly used in quasi-professional cinemas.
- Active: Amplified and adjustable, it offers enhanced performance and is suitable for all uses, from audiophiles to home theater enthusiasts.
Selection criteria
For a high-performance subwoofer, here are the key elements to consider:
1. Construction
A good subwoofer should be solid and well-built. It should not resonate when gently hitting the cabinet. Solid construction with internal bracing guarantees better performance and durability.
2. Type of housing
- Closed: Precise, clean bass, ideal for refined listening.
- Vented: Powerful, deep bass, perfect for maximum volume, but with a more diffuse rendering.
3. Power
More power = less distortion when listening to very low notes. 400 W is enough, but 800 W+ offers a better margin. Some top-of-the-range models even reach 9000 W (e.g. Paradigm Signature Sub 2).
4. Format
- 8-inch: Enhances ambience, but limited for deep bass.
- 10-12 inches: Versatile, covering most needs.
- 15-inch: For total immersion and bass that's felt to the point of goose bumps.
5. Optimization and tuning
A good subwoofer offers several adjustments:
- Volume control: Indispensable.
- Phase adjustment: Prevents bass cancellations between subwoofer and main speakers. A variable setting (0-180°) is more precise.
- Cut-off frequency: Adjusts the transition between the subwoofer and the speakers for an even sound.
Good to know Phase works like waves in water. Two poorly synchronized sound waves can cancel each other out, reducing the impact of the bass. Proper adjustment avoids this phenomenon and improves sound reproduction.
Today's best technologies enable subwoofers to self-calibrate, thanks to a microprocessor that analyzes the room and adjusts the sound accordingly. The result: optimized performance for your space and equipment.
