Type-1B: While the mounting configuration

is the same as Type-1A, this network set-

ting provides a variation for when personal

taste, positioning or vehicle acoustics neces-

sitates more high frequency output from the

midrange and tweeter. Rear deck installa-

tion is one particular example where the

extreme off-axis positioning will require such

level compensation due to the natural roll-

off. Although this will also result in some

additional delay of the woofer, it does not

exert significant influence in this case. The

resultant acoustic crossover points are the

same as indicated above.

Notes:

•Highlighted tweeter level jumpers are the recommended settings for each configura-

tion, but user adjustment may be desirable.

•Transfer function simulations only illustrate the effect of the filter upon the input sig-

nal, and therefore do not represent the actual frequency response of the system.

•If separate channels of amplification are used (bi-wire or tri-wire mode), the appro-

priate signal link jumpers must be removed.
