HK Audio Premium Pro 115 XD2

A "Premium" Evolution Designed for Modular Sound Reinforcement

The PREMIUM PR:O series has established itself as a European benchmark in modular sound reinforcement systems, focusing on robustness, ease of use, and consistent performance. The Premium Pro 115 XD2 continues this legacy by featuring a low-resonance wooden enclosure, custom-designed components, and advanced DSP processing to provide a reliable solution for regular gigs, rentals, or versatile installations.

Intended Uses and Musicians

With its 15-inch speaker and extended low-midrange response, this powered speaker is particularly suited for bands, DJs, hosts, multipurpose rooms, and service providers seeking a speaker capable of operating without a subwoofer in many setups. It excels as a front-of-house speaker for small to medium-sized events, as room fill, or as a vocal/instrument speaker when maintaining body on sources (vocals, guitars, keyboards, brass, tracks) is desired.
Its Mic/Line switch facilitates adaptation to different sources, while the XLR output allows quick daisy-chaining of a second speaker. For stage monitoring, the dedicated mounting angle and DuoTilt setup offer flexible positioning depending on the stage and desired projection height.

DSP, Sound Reinforcement, and Ergonomics: A Ready-to-Work Speaker

DSP Processing and Quick Settings

The integrated electronics rely on bi-amplified Class D amplification and a DSP designed for immediate use. The preset selector allows switching between adapted curves, and the "Music / Speech" tone controller helps optimize intelligibility or musical impact within seconds, without complex adjustments.

Sound Coherence and Even Coverage

The 90deg x 55deg CD horn targets wide and controlled dispersion to effectively cover the audience while limiting energy loss outside the useful zone. The FIR crossover with a 48 dB per octave slope at 2.5 kHz contributes to a cleaner transition between low/mid and high frequencies, promoting better definition and stable projection, especially vertically.

Protection and Reliability in Real Conditions

To handle level variations and protect the speakers, the speaker includes protection circuits with separate Peak and RMS limiters for the HF and LMF sections. The result is a more consistent sound at high volume and more confident operation during performances.

Transport, Installation, and Handling

The MultiGrip handles are designed to improve grip in all positions, a real advantage when doing multiple setups and teardowns. The MDF enclosure, black finish, and metal grille backed with acoustic foam enhance durability in use. For installation, the speaker offers pole mounting with DuoTilt 3/7 and a specified installation angle of 42deg, allowing more precise sound direction depending on the configuration.
