In 2024, we received communication from Mr. Jürgen from team Iammad and agreed to provide product support for his speaker project. Since then, Mr. Jürgen has dedicated significant effort to designing the “Scarab” speaker, which has garnered widespread attention and indirectly boosted the sales of our Fast-6 model. We have always been grateful for this.
Months ago, we had to terminate our cooperation with Iammad. Given some statements made about our brand and products in their recent videos, we feel it is necessary to clarify the facts to avoid any misunderstanding.
Regarding the Reason for Terminating Cooperation
Iammad claimed that we “refused to supply goods,” forcing them to find another supplier. We would like to clarify the actual sequence of events. After the Scarab speaker gained attention, Iammad actively discussed an OEM partnership with us. We were not only willing to cooperate but also offered him the most favorable terms. However, during our negotiations, we discovered that while stalling us, Iammad had already placed orders with other factories to produce products that imitate the Fast-6. Given this situation, we formally notified Mr. Jürgen of the termination of our cooperation.
In short: Iammad team commissioned a third party to imitate the Fast-6 first, and we terminated the cooperation only after getting this discovered—not the other way around.
Response to the Technical Comparisons in the Video
In the latest video, Iammad compared the imitation product with the Fast-6. From a purely technical perspective, we would like to provide the following explanations:
Regarding the Basket: The basket used in the imitation product has a bottom diameter of only 86mm, which limits the maximum installable magnetic circuit diameter to approximately 100mm. In contrast, the Fast-6 features a magnetic circuit diameter of 110mm. Using the imitation’s basket would require reducing the size of the magnet and the T-yoke clamp plate. We insist on not compromising performance to save costs, which is why the Fast-6 adopts its current basket design.
Regarding the Magnetic Cover: The purpose of the magnetic cover is to protect the magnetic circuit, concentrate the magnetic field, enhance aesthetics, and facilitate installation and positioning. As it is inherently magnetic, the presence of external magnetic force is normal. The magnet cover is useful and certainly generates cost of fabrication.
Regarding the Internal Structure: As seen in the video, the Fast-6 not only possesses a larger magnetic circuit but is also equipped with an independent sub-magnet, which the imitation lacks. The sub-magnet enhances the range and intensity of the magnetic field, which also has a positive effect on mid-to-high frequency performance.
Iammad claims that the imitation—with its sub-magnet removed, magnetic circuit reduced, and magnetic field strength lowered from Fast-6’s 14,000 Gauss to approximately 11,000 Gauss—sounds better than the Fast-6. While audio evaluation is subjective and we leave it to the listeners to judge, from a purely technical standpoint, reducing magnetic circuit specifications and cost while claiming superior performance is a perspective we find difficult to reconcile with established engineering principles.
Introduction of Fast-6S
In light of the above situation and the need for series upgrade, we have launched our latest model, the Fast-6S. The core technology of a loudspeaker lies in the cone; true disruptive upgrades come from innovations in cone materials and structure, not from imitating and downgrading existing designs. The Fast-6S embodies this philosophy: on the same enclosure, Fast-6S has achieved comprehensive improvements in sound fullness, imaging clarity, and musical expressiveness simply by upgrading the cone.
The Fast-6S is now open for pre-order, and we welcome both new and existing customers to experience and compare.
Thank you for your continued attention and support.
