@trevor – OK, so with a Dual Voice Coil (DVC), you have 2x4Ohm coils you have to hook up. That means, depending on hooking them up in series or in parallel, you wind up with 8Ohm or 2Ohms, respectively. Now, the lower the Ohms, the harder it is for some amplifiers to drive. In fact, at 2 Ohms, you could burn out many amps. So if looking for a 4 Ohm speaker, you would want either a 4 Ohm, or a DVC of 8 Ohm so that in parallel it drops it to 4 Ohm, or a DVC of 2×2 Ohms, so that when you run it in series, it increases to 4 Ohm.
The Epique you chose is dual 4 ohm, so you would want to go series, most likely, with the home deployment.
