Hand Blown Glass Speaker
The new StoneBjelk speaker series have been designed to be completely transparent. This makes the speaker blend in everywhere while still adding a cool design feature to your home. Our ambition have always been to make speakers that look more like an designed art piece instead of hiding them.
We build the cabinet of hand blown glass that sits on a wooden frame with transparent rubber pads. After that we put in the 18K gold plated connectors as well as the internal OFC copper cable braided in the fabric color of your choice. We fit the speaker driver with silicon glue and a rubber damper to minimize the vibrations between the speaker driver and the hand blown glass. At last we fit the StoneBjelk brass logo and oil/stain the wooden frame according to your choice.
The inside volume of the speaker cabinet is 1,6 Liters and the total weight of the finished speaker is 0,8 Kilos (This can slightly differ since everything is handcrafted). For measurements check our technical drawing down below.
Every speaker comes with a 1,5 Meter OFC copper cable braided in the fabric color of your choice. The cable connects to your amplifier with 18K gold plated banana connectors.
The Alpair 5 Generation 2 is a pure Free-to-air Single Suspension Full-Range audio driver. This new Alpair 5 is more advanced than its first generation version. The new 5 operates only using its all-new single front suspension.
This design retains designer Mark Fenlon’s classical mechanical engineering approach to reduce mass and extend long throw operating capacity. Mark, along with Evan Yu and the engineering team spent several months of research removing mechanical restriction from the ultra thin coil body. Traditional driver designs use a “spider”, a suspension device located behind the driver’s cone. Bonded to the coil, it physically restricts a coil's ability to transfer mechanical-acoustic signals to the cone. Some other drivers use damping fluid, springs or other devices, all of which produce losses. This new Alpair 5 design completely removes all these restrictions. Its coil locates cleanly between the driver’s cone and motor sub-assembly, making the new 5 a pure free-to-air mechanical design.
The accuracy requirement for this new Alpair 5 component design, engineering, and detailed assembly goes well beyond typical commercial audio-driver manufacturing. The front suspension operating tolerance is measured in milli-newtons. Production Alpair 5 drivers are made to within +/- 2.5Hz @ F Zero. All production units are then pair matched to with +/- 1Hz @ F Zero.
The result is a detailed balanced sound representation across an ultra wide frequency band for this class of small driver.
