Tweeter Mounting
When flush or surface mounting tweeters, make sure the
desired location can accommodate the hole size and depth
required. Mount the 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 cover
there is a jumper marked “TWEETER” + 2dB, 0 or - 2dB. Tweeter attenuation can be achieved by moving
the jumper to the appropriate position. The 0dB position has no attenuation effect on the tweeter.
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 provides 15-20% of the total power to the extra
speaker and is unfiltered or full range.
