The Olympus OLM1615 also includes a die-cast aluminum chrome speaker frame, front-plate & voice-coil cooling, a double-laminated integrated spider-tinsel lead design, and a 3” multi-layer extreme-temp dual 2 ohm voice coil configured to handle extreme levels of power. The Hifonics Olympus OLM1615 is priced at $329.99, $20 greater than its smaller peer, the OLM1612. According to Hifonics, the OLM1615 (and its peer) is so powerful that consumers are guaranteed to “feel the power the Gods themselves from these subwoofers.”
