10TW3 Dual Voice Coil Wiring
Please Note:
The TW3 is a dual voice coil driver.
BOTH voice coils must be connected to the amplifier
(in series or parallel) for the speaker to operate
properly. To accomplish this, each TW3 features a pair
of main input connection push-terminals for each
voice coil. Verify that the connections are properly
configured based on these wiring diagrams to
achieve the desired load prior to sending signal to
the subwoofer.
All specifications are subject to change without notice.
* Xmax specifications are derived via one-way voice coil overhang method with no correction factors applied.
** Efficiency (1W/1m) is not an accurate indicator of a subwoofer’s output capability and should not be used as a comparison to
other subwoofers to determine which one is “louder” !
*** Re (DC resistance) is measured with the voice coils in series, for parallel-wired specification divide Re by 4. All other specifications
remain the same.
