Hemispherical Polymineral Cone with Inverted Structural Domeô (ISD) Means high rigidity under pressure for accurate linear control, low enclosure pressure loss to reduce "pump-down", high internal dampening, and excellent sunlight, pollution and moisture resistance
WARG (Wrap ARound Gasket) Instead of using cork gaskets, which can separate, the Comp Woofers have a one piece gasket that wraps around the front and back of the mounting flange. It is more durable and ergonomically pleasing to the eye. We learned from other previous models the cork gaskets could tear off or if you were transplanting the speaker into another box, they could stay adhered to the old box causing you to order a replacement. These problems are eliminated with the new rubber gaskets. They not only look better, but also function better by eliminating the chance for air leaks.(provided the box is built correctly!) We still recommend if you are carpeting the box, to cut away any carpet that is under the woofer mounting flange.
SSD (Spun Spoke Design) The basket not only looks impressive, but it is extremely functional. This stamped steel basket provides a solid foundation for the motor assembly insuring that all the parts work together in harmony and prevent shifting or misalignment. Without a solid foundation, the speakerís various parts could shift under extreme excursion causing premature failure and add unwanted noise to the music. If misaligned, the voice coil could rub the inner wall of the motor structure and thus exposing the bare windings, which would cause speaker failure. The same thing happens if the coil former rubs the pole-piece. The damaged former exposes the windings causing speaker failure. When other speakers are pushed to their limits they tend to make noises that add coloration to the music. When youíre LIVINíLOUD you only want here the music the artist intended you to hear, not a bunch of unwanted ringing.
Perimeter Venting Without the perimeter venting along the side of the speaker, hot air would be trapped in with the voice coil. This will cause the structure to heat up quicker and cause power compression, which results in decreased output, as well as shorter speaker life. Perimeter venting causes a vortex cooling effect around the coil which exchanges the hot air around the voice coil for cooler air outside the speaker. It also releases pressure from under the spider to allow the speaker to work in a more linear fashion. All of this translates into cooler operating temperatures which will allow the speaker to sound and perform better.
Blackened One Piece Uniplate with Vented Hyper-Extended Pole 1. Provides enhanced heat transfer for cool operation and maximum power handling. The heat is transferred from the pole piece to the back plate, effectively acting like a radiator in an engine. This lowers the operating temperature of the voice coil. Note:The increase in temperature increases the impedance of the speaker. This results in lower output and is referred to as Power Compression. 2. Reduces non-linear magnetic fields around the voice coil gap for superior cone motion control. The extended pole assures the voice coil is always in the magnetic field when moving peak to peak. When the speaker reaches itís Xmax, the voice coil is still in the gap between the pole piece and magnet structure due to its extended pole-piece. 3. Releases pressure under ISD for freer cone motion and enhanced low frequency response. Air trapped under the ISD is forced out though the pole-piece to allow the cone to move freely. Heat and pressure build up under the ISD and need to be rele weight: 13.50 (lbs) UPC: 876358000234 Model #: DELTA12B
