Hiro Junior's & Dire Straits Demo or How resistors shape the Hiro sound.

In this video, we dive into the fascinating world of horn speaker tuning by exploring how changing resistors atop the Hiro Junior horn speakers alters their sound, particularly in frequencies above 2K. Using the parallel L-pad access point between the horn's binding posts, we demonstrate how shunting voltage (audio) to ground with resistors of 1 ohm, 0.5 ohms, and 0.25 ohms affects the horn's volume and tonal characteristics. We illustrate these changes with sound clips from Dire Straits' iconic track "So Far Away," showcasing the gradual decrease in horn volume and treble as the resistor values decrease. At the end of the video, we present a comparison test: one clip recorded from the Hiro Junior speakers using RODE NT1A microphones and a Tascam UH7000 high-resolution ADA, and another clip from the direct FLAC file of the song. However, recording a song from speakers engineered to closely match the original FLAC is inherently challenging due to several factors: Room Acoustics: The room introduces reflections, resonances, and absorption that color the sound, making it difficult to replicate the pristine clarity of a digital master. Microphone Placement: Even with high-quality mics like the RODE NT1A, capturing the exact tonal balance of the speakers requires precise placement and an acoustically treated environment. Speaker Characteristics: While the Hiro Juniors are designed for accuracy, no speaker can perfectly replicate the flat response of a digital master, especially in a real-world listening space. Human Perception: Our ears and brain interpret sound differently in a room versus a controlled studio environment, adding another layer of complexity to the comparison. This video highlights how even small changes, like resistor values, can significantly impact the sound, but also underscores the difficulty of achieving a perfect match between a live speaker recording and a digital master. It’s a testament to the art and science of audio engineering!
