The Topp Pro FLX 3 is engineered for high-reverberation and acoustically challenging environments, delivering clear, intelligible sound where traditional speakers fall short. Its design allows for flexible deployment in both distributed and array configurations, making it ideal for halls, event spaces, multipurpose venues, and houses of worship. With its impressive clarity and high SPL output in a compact size, the FLX 3 performs exceptionally well in echo-prone environments.
Thanks to its versatile installation options, the FLX 3 offers unmatched flexibility. It can be used as a standalone speaker in a distributed system design, where multiple units are strategically placed around the venue. This “divide and conquer” approach allows each speaker to focus on covering a specific zone, ensuring clear, even audio distribution without overloading any single area.
For applications requiring more focused sound projection and longer throw, the FLX 3 can be stacked in a vertical array configuration, functioning as a compact line array system. You can cascade up to 8 cabinets to form a tight vertical beam, which improves directivity and significantly reduces stray sound bouncing off reflective surfaces like ceilings and walls. This makes the FLX 3 especially effective for reverberant or echoey environments where clarity is critical.
For extended low-frequency performance, the ideal active subwoofer pairing is the Topp Pro S12, while the KS18S passive subwoofer powered by the TD500.4DSP amplifier provides a powerful and balanced system.
