Dual Voice Coil (DVC) is a single driver that has two terminals that accepts one or two wire inputs. Generally, the advantage of a DVC driver over a single voice coil driver is the flexibility in wiring options. TIC's DVC speakers (GS4 and TFS12) further adds the option to output stereo (two-channel) sound from a single speaker. This option is desirable when an user wants the same sound coming out of each speaker within the entire sound system and the amplifier does not offer a mono or bridged output mode. Typically, this setup works best in an outdoor setting where speakers are installed in separate listening areas or there are odd number of speakers.
There are 4 options: (see wiring guide here on how to wire each option)
- Standard (8Ω/input) - requires two channels out from amplifier
- Parallel (4Ω - single input) - requires one channel out from amplifier (should be mono or bridged)
- Series (16Ω - single input) - requires one channel out from amplifier (should be mono or bridged)
- Single Voice Coil Mode (8Ω) - not recommended. You should simply get the 8Ω speaker version (GS3, TFS6, TFS10, etc) if you are planning to use this mode.
