With each driver's coils in series and the three cups in parallel, the three present 1.33 ohms to a mono amplifier. With each driver's coils in parallel and the three in series, they present 3 ohms. Three drivers do not reach the round loads a pair does, so check the result against your amplifier's minimum stable impedance before powering up. Each EPICX8 D4 has two 4 ohm voice coils, 8 ohms in series or 2 ohms in parallel. With each driver's coils in series and the three cups in parallel, the three present 2.67 ohms to a mono amplifier. With each driver's coils in parallel and the three in series, they present 6 ohms.

Recommended amplifier: 150 to 210 W RMS per driver, 450 to 630 W RMS for the full set of 3. Travel, not heat, sets the top: the cone reaches Xmax at 213 W per driver with a 25 Hz subsonic set, under the 400 W rating. The top of that range needs the 25 Hz subsonic; without it keep each driver under 197 W.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"po-section\"\u003e\n\u003ch2\u003eBuilt in Tennessee, Backed by Audio Intensity\u003c\/h2\u003e\n\u003cp\u003eCut and assembled in Tullahoma, Tennessee on our own CNC equipment.
