Exclusive Early Bird Invitation: The DrBAcoustic Laboratory WN-RA Series

Featured

Posted on by

Following the official launch of the #finalgeneration DrBAcoustic Laboratory WN-RA Series, I am pleased to announce an exclusive 20% Early Bird discount on standard list prices. This offer is strictly limited to the first 5 customers.

The WN-RA series represents the absolute zenith of ultra-high-end audio—both in breathtaking acoustic performance and manufacturing execution. Because the mathematically optimized horn profiles are highly complex, they require state-of-the-art 5-axis CNC machining to be milled from premium birch multiplex with absolute high precision. Following this advanced technological production stage, every single horn is painstakingly hand-sanded and finished with premium high solid oil. No shortcuts are taken, and no compromise is made in materials, geometry, or manufacturing.

Naturally, manufacturing of this class commands a substantial investment. These products are built for uncompromising audiophiles who appreciate ultimate structural and acoustic quality, not for bargain hunters looking for budget solutions. While the pricing reflects the immense manufacturing overhead and elite tier of these components, it remains strictly fair and transparent. For perspective, any WN-RA horn arrives completely finished—expertly sanded and oiled—and includes two bespoke, heavy-duty transport crates as standard to ensure absolute protection.

This initial tier offers a rare window to acquire a definitive masterpiece of horn technology under preferred terms. Because this promotion is capped at just 5 build slots, it will conclude as soon as these positions are filled. For serious inquiries and detailed configurations, please get in touch via email.

Announcing the Launch of the DrBAcoustic Laboratory WN-RA Series: The Zenith of Horn Technology Comes Home

Posted on by

After years of relentless research, mathematical derivations, and uncompromising engineering at the DrBAcoustic Laboratory, I am thrilled to officially announce the launch of the #finalgeneration WN-RA Horn Series.

This series represents the culmination of my lifework. It is the definitive answer to a challenge that has divided the audiophile world for decades:

How to achieve the effortless dynamics and lifelike resolution of professional horn speakers without the typical artifacts, throat-glare, or narrow “beaming” coloration.

The WN-RA series achieves a true quantum leap in acoustic physics. Through proprietary mathematical algorithms, it guarantees seamless acoustic loading all the way down to the acoustic design frequency while simultaneously ensuring an incredibly wide, deep, and rock-solid stable holographic soundstage—completely free of diffraction and traditional horn artifacts.

With the official launch, the WN-RA series splits into two meticulously optimized pathways:

1. The PVA Series (Professional Venue Arena & Ultra-High-End Fidelity)
Engineered for custom architectural audio, premium listening bars, and intimate theaters. It proves that massive, wide coverage and breathtakingly natural resolution can co-exist flawlessly in demanding pro-tier applications.

Final Generation William Neile Acoustic Loading Horn Series – Part II

The next product in my #finalgeneration acoustic loading optimized horn series is the WN300RA. I thought long and hard about whether I should develop separate versions for 1.4-inch and 1.5-inch drivers, and in the end, I decided to offer a product with maximum flexibility. Since the #finalgeneration series was designed from the ground up with interchangeable adapters, two different adapter versions are available for the WN300RA (1.4-inch and 1.5-inch entry), allowing virtually any driver available on the market to be mounted. The screw mounting slots offer additional flexibility for different screw mount distances. The size for WN300RA is based on the well-known WN300ALO, which has recently found a very satisfied new owner. Since then, my design has undergone dramatic improvements, including through #ALOV2 and #SQPV2 and the use of a variety of additional different profile functions. This has significantly improved directional control in all radiation planes and substantially increased the acoustic loading capabilities.
