Car active subwoofer

The loudspeaker is designed to fit within a fixed enclosure, with its outer diameter matching the diameter of the paper tube for proper installation. The speaker is mounted on wood, with a wooden brush applied to the upper chamber, which is securely attached to the central conduit. The speaker selected is an 8-inch, 16.5-inch woofer, configured with two units wired in parallel and opposite phase. The amplification is handled by a TDA2005M integrated circuit, designed for audio power applications, as illustrated in Figure 9-47. This configuration allows for a significant power output, suitable for automotive audio systems. Although the subwoofer's power output may seem limited, user experience indicates satisfactory performance. The subwoofer is installed beneath the back seat, ensuring that bass signals are effectively captured from the speaker while maintaining correct phase alignment. This subwoofer can also be configured as a 50W amplifier for home theater systems, providing commendable audio performance.

The loudspeaker system described is engineered for robust audio reproduction with a specific focus on bass response. The integration of the 8-inch, 16.5-inch woofer in a parallel configuration allows for enhanced sound output, ensuring that the system can handle a wide range of frequencies while maintaining clarity and depth in bass tones. The choice of the TDA2005M amplifier is particularly advantageous due to its capability to deliver high power output in a compact form factor, making it suitable for both automotive and home audio applications.

The mounting of the speaker on wood provides structural integrity and minimizes vibrations that could distort sound quality. The wooden brush applied to the upper chamber may serve to enhance acoustic properties, potentially aiding in sound diffusion and resonance control. The careful consideration of speaker phase is crucial; incorrect phase alignment can lead to phase cancellation, resulting in diminished audio performance. Therefore, attention must be paid during installation to ensure that the subwoofer operates optimally.

The placement of the subwoofer beneath the back seat is a strategic design choice, allowing for effective use of space while providing direct access to bass signals. This positioning can enhance the listening experience by creating a more immersive sound field, especially in vehicle applications where space is often limited. For home theater setups, the ability to configure the subwoofer as a 50W amplifier expands its versatility, enabling it to deliver powerful audio in a domestic environment. Overall, this loudspeaker system is designed to deliver high-quality audio performance with a focus on bass response, making it an excellent choice for both mobile and stationary audio systems. Between fixed loudspeaker that period. Its outer diameter must be consistent with the paper tube diameter to facilitate fixed speakers, and in its outer open on a walk trough, the speaker mounted on wood, wood brush on the upper chamber, which is fixed to the central conduit, speaker election 8t16.5 inch woofer with two parallel and opposite phase. Amplifier using TDA2005M, then into BTI- form, as shown in Figure 9-47. This is a vehicle that can provide greater power output circuit in the form of audio power, although subwoofer in terms of its power output somewhat enough, but in actual use, the effect is quite satisfied 6 subwoofer is placed in the use of under the back seat, the bass signal can be picked up directly from the speaker t pay attention not to pick the wrong phase.

This subwoofer can be configured as more than 50w subwoofer amplifier for home theater systems, the effect is also good by the
