  Color Code

Purple - 2   Top Plate *

Yellow - 5   Voice Coil

Darker Blue - 4  Magnet  North on top,  South on the bottom

Medium Blue - 3  Pole Piece  Area between 2-3 is the "gap"

Light Blue - 1 Back plate

Red - 6  Spider (fabric)

*The magnetic field is artificially bent 90 degrees across the "gap" by the top plate limiting performance

Note: The bottoms of both cut away pictures are the rear ends of the drivers. The cones & baskets would be on top facing up. They are not shown in the diagram for simplicity.


  • Neo: new Special High temperature Neodymium with higher MGO (Mega Gauss Oersted). Stronger magnets for higher efficiency and lower distortion.
  • Radial: magnet ring is 2x taller than the coil height. This Neo Ring has its axis physically parallel to the voice coil axis, but the magnetic feild is orientated with its North-South magnet poles acting perpendicular to the entire coil across the gap. This approach eliminates the need to do what conventional woofer designs must do. Conventional woofers artificially bend the flux 90 degrees , perpendicular to the coil across the gap with a thin steel top plate. The problem with this is that the top plate thickness becomes your limit and often becomes magnetically saturated. What typically happens is that the flux intesity level near the top plate in the gap is high but only acts on a small portion of the coil windings. In the B-Hive Motor the flux intensity level is lower at any given point across the bigger gap but acts over a larger area. All of the coil windings get the same amount of flux right up to the X-Max Limit. The net result is that the proper BL is achieved because the the flux or "B" cross product "L" or Length of wire gives us the motor strength. We simply have more "useable turns" in the gap. The T-S parameters of the woofer stay the same over time under a variety of operating conditions therefore you have less variability when you tune your system.
  • Technology: that extends beyond the competition with features like improved Dual (mirror imaged) Aramid spiders with the leads woven in. Honeycomb Composite Cone material thats ultra strong yet light weight. A low mass proprietary Progressive roll surround that's specially treated to be strong for high excursion and well damped for good frequency response. A Copper cap on the pole on the inside of the pole piece to conduct heat, lower the inductance rise with frequency and lower the distortion. Check out the Innovative approachs we have taken to solving problems in the real world like a "Screw-off Motor" for field replacement of cone/basket assembly and the abilty to retrofit(bolt-on) to some of our older designs already out in the field to increase performance. We focus on Excellence in both design and service. We invite you to listen to our story.
