Wolf Von Langa WVL 12639 SON: Award-Winning Field Coil Loudspeaker in Malaysia
If you're searching for the best high-end loudspeakers in Malaysia — something that goes far beyond what conventional passive speaker design can offer — we're excited to introduce you to the Wolf Von Langa WVL 12639 SON, a field coil driver speaker now available here at Audio Image.
This isn't just another premium hi-fi speaker. As one of the most talked-about audiophile loudspeakers in the high-end audio world, the SON has picked up serious international recognition, including The Absolute Sound's High-End Product of the Year and Editor's Choice Award. If you're comparing high-end speakers for audiophiles or exploring field coil speaker technology for the first time, this guide covers everything you need to know about the WVL 12639 SON.
What Makes the WVL 12639 SON Different? Field Coil Driver Technology Explained
Most loudspeakers on the market today rely on permanent magnet drivers. The SON takes a different approach entirely, built around field coil driver technology — a design principle that dates back to the 1920s but is rarely seen executed at this level in modern high-end loudspeakers.
Electric Orchestra: How Field Coil Drivers Work
Instead of a fixed permanent magnet, the SON's drivers use powered electromagnets to propel the cone. These electromagnets are charged by an external unit, creating an incredibly powerful motor system. The result is a stable, constant magnetic field that delivers remarkably smooth and consistent sound — something permanent magnet drivers simply can't replicate in the same way. For anyone researching field coil speakers vs permanent magnet speakers, this is the core difference that sets the SON apart.
Way Down Deep: Deep Bass Extension and Soundstage
At the heart of the SON sits the WVL AC-2676 field-coil driver, with an effective cone diameter of 258mm — nearly 11 inches. It's built from Wolf Von Langa's own hydrophobic paper, engineered to be stiff yet remarkably light. Paired with a passive radiator mounted on the back of its sealed cabinet, this driver produces an expansive soundstage and genuinely deep, high-fidelity bass extension — a key reason this speaker is favoured by serious audiophile bass speaker enthusiasts.
Floats and Sings: Mundorf Air Motion Transformer Tweeter
The Mundorf Air Motion Transformer (AMT) midrange tweeters are mounted on a translucent, acoustically inert material, giving them an almost free-floating quality. They sit in an elegant open structure that can be freely positioned on top of the speaker, allowing you to fine-tune the speaker's high-frequency response to your listening room.
Tune to Taste: Adjustable Dynamics for Precision Listening
Because the SON uses field coil driver technology, you can actually adjust the current flowing into the drivers — giving you precise, adjustable dynamic control over your music in a way that's simply not possible with conventional passive speaker designs. This tunability is one of the standout features audiophiles look for in a customisable hi-fi speaker system.
Structurally Sound: Premium Build Quality and Cabinet Design
Rather than the typical metal cage most drivers are mounted in, the SON's driver is attached to a massive 40cm x 40cm slab of aluminium, reinforced with internal struts and bracing. This premium loudspeaker cabinet construction ensures that the driver's bass energy is transferred efficiently into the room rather than lost to cabinet resonance.
Drives Easy: Easy to Pair With Low-Power Amplifiers
Despite its high-end performance, the SON is surprisingly easy to drive with low-powered amplifiers. With a continuous efficiency of 95dB, continuous power handling of 150 watts, and peak compatibility of up to 1,500 watts (10ms), even modest amplifiers can bring out its best. That also makes low-volume, late-night listening a genuine pleasure — a rare quality among high-efficiency loudspeakers of this calibre.
