Product Summary

The TQ-440SP is a compact three-way self-powered full range enclosure including integral power amplifiers and control electronics. The use of active power amplifier technology ensures an exact match between amplifier and speaker for optimum acoustic output, and offers exceptional ease of use by combining the entire electro-acoustic system in one convenient, easily transportable physical package.

It incorporates a custom-designed co-axial 12"/1" combination LF/HF driver in an optimally tuned vented trapezoidal enclosure handling the low and high frequency bands. The critical mid-range frequencies are handled by a proprietary 6.5" cone transducer on a 60° horizontal by 40° vertical nominal disperion waveguide, loaded with a TurboMid device.

The exclusive use of cone transducers in both the low and mid frequency bands produces a seamless transition at the crossover frequency, with the result that all of the critical vocal range right up to 8kHz is lower in distortion than compression driver-based designs. In addition the 6.5" mid-range driver is a highly efficient device, and is able to handle large amounts of amplifier power. The remaining high frequencies above 8kHz are effortlessly handled by a 1" compression driver, operating in a relatively narrow pass band, and therefore subjected to minimal mechanical stress. The mid and high components are physically time aligned within the enclosure, ensuring perfect time arrival at the listener's ear. When compared to conventional two-way designs the TQ- 440SP is able to offer higher SPL, significantly lower distortion, and unsurpassed vocal projection capabilities in an equivalently sized physical package.

A rear panel switch selects optimised profiles for speech or music applications, enabling real flexibility of use.

The TQ-440SP is a full range loudspeaker, and used by itself will provide high quality audio for all speech and many music reproduction applications. In order to extend the effective bass frequency range of the loudspeaker by a further octave the use of the complementary TQ-425SP subwoofer is recommended.

TQ-440SP specifications

The Turbosound TQ-440SP is a powerful and versatile subwoofer that has made a significant impact in the world of professional audio. Designed with precision and performance in mind, the TQ-440SP stands out for its ability to deliver deep, impactful bass while maintaining clarity and balance across various applications.

One of the main features of the TQ-440SP is its robust construction. Built with a durable wooden enclosure, it provides both strength and resonance control, ensuring that the sound produced is not only loud but also clean and distortion-free. This is essential for live sound reinforcement, as well as installed applications in venues such as clubs, theaters, and concert halls.

The TQ-440SP is equipped with a high-performance 18-inch driver that is engineered to handle high power levels and produce exceptional low frequency output. This driver technology allows for an impressive frequency response, reaching down to 30Hz, which is crucial for genres that rely heavily on bass, including electronic, hip-hop, and orchestral music.

Another noteworthy technology in the TQ-440SP is its advanced system processing. The integrated digital signal processor (DSP) features advanced algorithms for crossover, limiting, and equalization, allowing users to tailor the subwoofer's performance to match specific room acoustics or system configurations. This capability enhances overall sound quality and ensures optimal performance, regardless of the setting.

Moreover, the TQ-440SP is designed for easy integration with other audio components. Its dual-input connectors accommodate a variety of input options, making it versatile enough to work with different mixing consoles and amplification setups. Additionally, it can be combined with Turbosound's other loudspeakers to create a cohesive sound system that delivers full-range audio experiences.

Portability is another consideration in the design of the TQ-440SP. Weighing in at a manageable level, it can be transported and set up with relative ease, making it an excellent choice for mobile applications such as touring and events.

Overall, the Turbosound TQ-440SP is more than just a subwoofer; it is a comprehensive solution for sound professionals seeking high-quality, reliable low frequency performance. Its combination of powerful drivers, advanced processing, and practical design features make it a go-to choice for demanding sound applications, setting a standard in the realm of professional audio equipment.
