DD AT-28
The DD-AT28 is a wide-band tweeter with a 28mm coil diameter. It uses two rear chambers, one behind the voice coil and a second milled aluminum chamber behind the motor. Shorting rings are used in the motor to flatten the impedance curve and wick away heat from the coil windings.

DD W6.5
The DDW6.5 mid-bass/mid-range driver was designed to deliver the widest possible bandwidth while providing a fast transient response with high levels of long term power handling. The cone is a composite blend of Kevlar fiber, carbon fiber and a very stiff and lightweight resin. This combination has an excellent strength to weight ratio that is light enough to react quickly to complex signals yet rigid enough not to flex when subjected to extreme power levels. The surround is a well dampened rubber half roll. The motor structure incorporates long magnetic field technology which ensures precise control over cone excursions and efficiently dissipates heat from the voice coil. The voice coil former is made from black anodized aluminum layered with arimid fiber and wound with the wire capable of enduring temperatures to 500 degrees F. The dual flat spider suspension is made from synthetic materials to give the smoothest response and long lasting durability. The lead wires are laminated into the layers and run across opposite sides to even out weight over the moving system. The leads are terminated in 10ga. copper wire for the most efficient electrical transfer. The DDW6.5 makes an excellent subwoofer in space limited systems and great for high powered midbass applications.
