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 5,5 Liters and the total weight of the finished speaker is 1,5 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 7 Gen. 3 represents a large step forward in the design and production of “extended” fullrange audio drivers. In its size class, this Alpair 7 currently delivers the widest frequency range*. The usable range now extents to 32-kHz above 80dB. Thatʼs higher than many tweeters!
This Alpair 7 has an advanced damping systems such that it delivers a “near flat” response across its range. The 7 employs a rear ring-clamped suspension system and a new torque loaded rear suspension (spider). Both these components add pre-tension to the power-train. The result is improved linearity and damping on the moving components.
The acoustic performance of this driver is solidly placed in the “purist-audiophile” category. Its cone and power-train are the most micro-resonance sensitive made by Markaudio to date. The off axis responses and central stereo image emitted from this Alpair 7 are possibly best in class. Its cone profile and under-hung front suspension allow for a clean wide acoustic image making it easier to optimse box positioning in most listening environments.
The Alpair 7 Gen. 3 is near unique (if not totally unique). Its range, near flat response and special design features set it apart from other full-range driver of similar size.
