Seeflut Audio Carves the Qlang M4s From Solid Beech Wood

Seeflut Audio Qlang M4s floorstanding speaker in solid beech wood

The Qlang M4s is hand-built from solid beech wood with a resonance-optimized enclosure.

German boutique manufacturer Seeflut Audio has introduced the Seeflut Audio Qlang M4s, a fully active floorstanding loudspeaker hand-built from solid beech wood. Where most active speakers lean on injection-moulded cabinets or MDF veneer, the Qlang M4s is built one pair at a time by its maker, pairing a shallow, living-room-friendly footprint with the kind of DSP-controlled amplification usually reserved for studio monitors.

A Cabinet Carved, Not Assembled

At the core of the Seeflut Audio Qlang M4s is a resonance-optimized enclosure machined from solid beech, reinforced internally by a dense matrix bracing structure designed to keep the cabinet acoustically inert. Each housing is hand-glued, sanded in multiple stages and finished with natural flaxseed oil rather than paint or synthetic waterproofing, while the CNC-cut aluminum trim pieces are sanded, brushed and screen-printed by hand. Seeflut Audio pairs that cabinet with height-adjustable, ball-bearing feet that isolate the speaker from the floor without the risk of damage that traditional spikes carry.

Active DSP Amplification Built In

The Seeflut Audio Qlang M4s is a fully active, DSP-controlled two-way design, combining a Morel silk-dome tweeter with a SEAS mid-bass driver on a coated paper cone, driven by a rear-mounted Hypex Class-D amplifier module rated at 2×125 watts. A DSP-based active crossover with individually programmed FIR filters handles phase alignment and frequency-range control, while a passive radiator system tuned to the cabinet volume extends bass response despite the speaker’s shallow depth. Each pair is built from matched drivers for channel balance, and every unit is custom-manufactured to order with a lead time of roughly 10 weeks — similar in spirit to other Hypex-based active designs we’ve covered, such as the Ex Machina Terra and Gravity monitoring system.

Pricing and availability

Seeflut Audio is launching the Qlang M4s under a tiered “Founders Edition” pricing structure: the first five pairs are priced at €9,900, the next ten pairs at €10,900, and the final five Founders Edition pairs at €11,900, before the price reverts to the regular €13,450 per pair. Founders Edition buyers within an 800km radius of the maker’s German workshop receive personal delivery, setup and room calibration at no extra cost, along with two premium power cords and two XLR interconnects included. The Seeflut Audio Qlang M4s carries a 5-year warranty and ships worldwide, with customs and taxes handled on request. Full pricing tiers and configuration options are listed on the official Seeflut Audio product page.

A One-Maker Operation

Seeflut Audio operates as a small, workshop-scale manufacturer rather than a conventional speaker company, with the Qlang M4s built and finished by hand rather than on a production line. That approach places the Seeflut Audio Qlang M4s alongside a wider trend of boutique, DSP-active loudspeakers from independent makers who combine off-the-shelf amplifier modules like Hypex with distinctive, self-built cabinetry — trading the scale of larger manufacturers for closer control over materials, finish and final voicing. The personal delivery and in-room calibration offered with the Founders Edition underlines that hands-on approach, extending it from the workshop into the buyer’s own listening room.

Publisher

Marco Lisi is the publisher of Best of High End, part of AV Concepts BV. His path into audio started early: as a teenager he was drawn into the world of free radio, presenting shows and living immersed in music every day. In his early twenties he ran his own production studio for five years, creating jingles and commercials — hands-on training in sound design, pro-audio workflows, and critical listening through studio monitors that still shapes how he evaluates gear today. He also spent years DJing in clubs before moving into publishing, first at two earlier online magazines before founding Best of High End. His hi-fi and home cinema passion was inherited from his father, an inveterate system-swapper. Marco's first setup — a confirmation gift — paired AKAI separates with entry-level Bowers & Wilkins speakers, a brand he stayed loyal to for years as his system grew from stereo into full surround and home cinema. Like many enthusiasts, he went through an extended "audiophile" phase chasing the next upgrade, before settling into a more grounded view: gear as a means to enjoy music and film, not an end in itself. Years of critical listening have given him a well-trained ear — the ability to characterize a system or pinpoint a change in the chain quickly and accurately. Just as important, his teaching background (a Belgian "regent" degree in Dutch language) gives him the tools to translate those listening impressions into clear, readable writing.
