    Product details

    SB Acoustics Satori MR16P-4 6.5” Midrange

     

    The MR16P-4 is built on a cosmetically attractive six-spoke frame that has a minimal reflective footprint behind the cone to reduce reflections and a completely open area beneath the spider mounting shelf for enhanced cooling, both highly desirable attributes. Additional cooling is provided by venting the voice coil former and a 12 mm diameter pole vent. The spider mounting shelf itself is pinned to the frame to limit vibration transfer from the frame to this part of the suspension system. The neodymium motor cup attaches to the bottom of the frame and has a separate cosmetic/heatsink part that looks like the continuation of the frame attached to the peripheral of the motor.

     

    The motor is comprised of a neodymium ring magnet and the cup that completes the field and forms the gap area. In addition, there is an overhung copper sleeve shorting ring to reduce distortion. The device uses a 36 mm (1.4”) diameter voice coil with a nonconducting fiberglass former wound with round copper-clad aluminum wire (CCAW) and terminated to a pair of gold-plated terminals located on opposite sides of the frame to minimize rocking modes.

     

    The cone and the dust cap material are also unique and composed of 60% pure Egyptian papyrus parchment fibers, a very expensive but light and stiff material. Suspension is provided by a nitrile butadiene rubber (NBR) surround that uses a special vertical and horizontal attachment process, along with a Dr. Kurt Muller Bimax spider. Bimax is purported to have less twisting tendencies compared to other cloth spider materials.
