Tweeter Mounting

When flush or surface mounting tweeters, make sure desired location can accommodate the hole sizes and depth required. Mount cup using provided hardware, flush mount illustration shown on right. Mount surface cup at desired angle with

provided screws in tweeter mounting kit. Snake

speaker wires through tweeter cup, connect tweeter to wires, and snap tweeter into cup by aligning the notches. Be careful not to push on the center of the tweeter grill.

Crossover Programming

Each D3 component set comes with a pair of model specific programmable crossovers. Under the clear cover there are two jumpers, one marked “TWEETER” and one marked “AXIS”. -2 dB tweeter attenua- tion can be achieved by moving the “TWEETER” jumper to the -2dB position. The default “reference” position has no attenuation effect on the tweeter or is 0dB. The “AXIS” jumper swaps the tweeter phase 180 degrees. The default position is “off axis” for mounting in dash boards, doors, and a-pillars. The “on axis” position is for tweeter positions that fire directly at the listening area like in custom kick pods.

RAF Outputs

Each D3 Component crossover has a third set of outputs marked “RAF”. This stands for Rear Acoustic Fill. This output can be used to power an additional speaker off the same channel without affecting the impedance load on the source unit. This output allows 15-20% of the total power to the extra speaker and is unfiltered or full range.
