The Topp Pro APX 28HA is a versatile and powerful 2-way active line array loudspeaker that boasts exceptional sound quality, thanks in part to its premium Celestion drivers. Its lightweight and durable construction make it perfect for use in live performances, DJ events, conferences, and more. Featuring two 8-inch neodymium Celestion woofer and two 1-inch neodymium Celestion compression driver, the APX 28HA delivers clear, detailed, and balanced audio. The built-in amplifier of 3200 Watt peak provides efficient power management and allows for easy setup and operation.

Topp Pro APX 28HA is more than just a powerful 2-way active speaker - it also boasts a range of advanced features that make it an incredibly versatile and flexible sound solution. One such feature is its built-in DSP capability, which enables fast and flexible setup, with DSP presets that can be easily recalled from the rear of the product.  The DSP processor included in the APX 28HA allows you to fine-tune the sound to your specific needs to suit different environments and applications. And because the DSP is built-in, there's no need for external processing gear, which saves you time, money, and hassle.

But the flexibility of the APX 28HA doesn't stop there. This is a networkable line array system, which means you can access the DSP and other features via computer over a RJ45 network connection. This allows for even more precise control and customization, with the ability to save and recall settings for specific events, venues, or applications.

Topp Pro APX 28HA also features a waveguide horn that enables precise control of directivity down to 10 degrees. This allows you to focus the sound exactly where you want it, minimizing unwanted reflections and maximizing clarity and intelligibility. The waveguide horn also helps to reduce distortion and coloration, resulting in a more natural and accurate sound. And because it allows for such precise control over the directivity of the speaker, you can achieve a more consistent sound throughout the listening area, regardless of the acoustics of the room.

Designed with portability in mind, the Topp Pro APX 28HA features ergonomic handles and a lightweight construction, while its rugged design and protective grille ensure it can withstand the rigors of touring and live performance. Topp Pro APX 28HA is a high-quality active line array loudspeaker that delivers exceptional sound quality, thanks in part to its Celestion drivers and its 32 bit, 24bit/48kHz audio conversion AD/DA DSP, making it an ideal choice for professional musicians, DJs, and event organizers.
