Dayton Audio recently introduced matching passive radiators to their Epique 5 ½” and 7” subwoofer lines. This project employs the Dayton Audio Epique E180HE-44 Subwoofer and matching Epique E180HE-PR Passive Radiators along with the Dayton Audio SPA300-D 300 watt subwoofer plate amplifier in a small 11” cube. It’s a great combination!

UPDATE: Listening to "The Polar Express" with this and two small two-way speakers. I had the volume really cranked up to hear the weak dialog and forgot to turn it down during the 'runaway train' scene and I bottomed this driver out... BANG!!! Loud and scary... I jumped for the remote but there was only one noise. I bottomed out the voice coil on the back-plate. It survived... No bad noises afterwards, it seems fine and no scraping or nasty sounds pushing the cone in. I got away with one there, but just to reiterate that this Epique 7" driver is at least made pretty tough just in case someone does push it a little too far. I continue to be impressed with it.
