Description

The Vitavox AK157 is a high-performance, 15-inch (38cm) cone-type woofer unit designed for heavy-duty professional audio and high-fidelity applications.
Perfect for a restoration project or a custom high-fidelity build.
Key Details & Provenance
Model: Vitavox AK157 (now 8 Ohm impedance).
The original AK154 15 Ohm basket/magnet assembly was professionally re-coned at some point in its life using an Original Equipment Manufacturer (OEM) Vitavox replacement cone assembly specific to the 8 Ohm AK157 specification. This essentially makes it a factory-spec AK157 in function.
Impedance: Measures to the 8 Ohm specification (approx. 7.5 Ω rated) of the AK157 model.
Visuals: Features a rigid die-cast frame and original high-quality fiber cone designed for excellent transient response in the low frequencies.
Why This Vitavox Driver?
Legendary Performance: Vitavox 15-inch drivers are often considered superior to many vintage Altec, JBL, and Klipsch counterparts by seasoned audiophiles, particularly when Horn Loaded.
Rare Opportunity: True OEM-spec re-coned units are hard to come by and highly sought after for authentic vintage restorations or bespoke systems.
Tested and Verified: The driver has been carefully tested for functionality, ensuring no voice coil scraping or other issue.
OEM recone kits are still available from the manufacturer @ https://www.vitavoxhifi.co.uk/ should you want to return it to a 15ohm unit.
