Key Benefits & Features

Superior Sound Clarity with High Sensitivity

Boasting sensitivities of 86 dB (HD-100) and 89 dB (HF-100), these HiFi speakers convert minimal power input into rich, detailed sound. The higher sensitivity of the HF-100 ensures even subtle audio nuances—like vocal inflections or instrumental harmonics—are reproduced with stunning accuracy, making them ideal for HiFi audio purists.

Premium Silk Dome Tweeters

Equipped with 20mm (HD-100) and 1” (HF-100) silk dome tweeters, the speakers deliver smooth, extended high frequencies without harshness. Silk’s natural damping properties minimize distortion, ensuring cymbals, violins, and vocal highs sound airy and authentic, a hallmark of true high end audio performance.

Robust Mid-Woofers for Balanced Bass & Mids

The 3” mid-woofers strike the perfect balance between warm midrange and controlled bass. Whether reproducing vocals, acoustic guitars, or basslines, the drivers maintain clarity across the frequency spectrum—no muddiness, no thinness. The HF-100’s wider freq. response (50Hz ~ 20KHz) dives deeper into low end, enhancing movie soundtracks and electronic music.

Versatile 4 Ohm Impedance

With a 4 ohm impedance, these speakers seamlessly pair with most HiFi amplifiers, AV receivers, and digital audio players. This compatibility ensures you won’t need specialized equipment to unlock their full potential, making them accessible for both beginner and advanced audio setups.

Compact & Stylish Design

The bookshelf speaker form factor is optimized for space efficiency. Measuring 120×200×160mm (HD-100) and 900×140×220mm (HF-100), they fit neatly on bookshelves, media consoles, or speaker stands without overwhelming your space. Their understated design complements modern and classic interiors alike.

30W Power Handling for Home Use

Rated at 30W power handling, the speakers deliver ample volume for medium-sized rooms—perfect for daily music listening, movie nights, or casual gatherings. The power output is calibrated to avoid distortion at high levels, ensuring consistent performance even during extended use.

FAQ

Are these speakers compatible with my existing HiFi amplifier?

Yes! The 4 ohm impedance is a standard specification, so they work with most HiFi amplifiers on the market. For best results, ensure your amplifier’s power output matches the speakers’ 30W power handling.

What’s the difference between HD-100 and HF-100?

The HF-100 offers higher sensitivity (89 dB vs. 86 dB) and a wider frequency response (50Hz ~ 20KHz vs. 70Hz ~ 20KHz), ideal for bass-heavy content. The HD-100 has a more compact dimension, better suited for tight spaces.

Do I need a subwoofer with these bookshelf speakers?

It’s optional! The 3” mid-woofers deliver decent bass, but adding a subwoofer enhances low-end depth for genres like hip-hop or movie soundtracks. For casual listening, the speakers perform excellently on their own.

How far should I place the speakers from walls?

To optimize bass response, place them 10-15cm away from walls. This reduces boundary interference and ensures a more balanced soundstage—key for HiFi audio performance.

Are the speakers durable?

Yes! They’re built with high-quality materials to withstand regular use. The silk dome tweeters and robust mid-woofers are designed for long-term reliability, making them a worthwhile investment for audio lovers.
