Epique E180HE-PR 7" Carbon Fiber Cone Passive RadiatorLike. No. OtherCombining world class performance with a reasonable cost, the Epique E180HE-PR 7" carbon fiber cone passive radiator from Dayton Audio is the perfect companion for the Epique Series MMAG Subwoofers. Featuring a carbon fiber cone, custom tooled suspension, and cast aluminum frame, the low FS of the E180HE-PR enables speaker designers to use smaller and lower tuned boxes without the excessive port lengths.
The included mass loading system gives you the flexibility to fine-tune low-frequency performance to your enclosure and target response. With three 30g disks included, the E180HE-PR can be configured from a 22 Hz resonant frequency with no added mass down to 16.3 Hz with all disks installed, allowing you to dial in deeper extension without changing your enclosure design.
High excursion requires flexible suspensionWhen designing the E180HE-PR, Dayton Audio paid extra attention to optimizing the suspension to guarantee unrestricted excursion without limiting performance. The large roll rubber surround was custom tooled for high excursion and a custom weighted spider was created to lower the FS for maximum performance and easier tuning.
Carbon Fiber Is All About PerformanceThe rigid carbon fiber cone gives the E180HE-PR retains a familiar look while offering a number of performance advantages. The woven cone has excellent damping properties which keep the active driver well controlled. Optimized cone and dustcap profiles make sure that there is no deformation when exposed to high stress so the smooth response and low distortion remain consistent even when pushed to high excursion
Cast aluminum frame holds everything togetherIn order to support its extreme excursion, the E180HE-PR uses a rugged cast aluminum frame. The minimalistic design of the frame both eliminates unwanted flex and provides ample room for the rear of the cone. 19mm of Xmech, and plenty of room behind the spider makes sure that you can push the limits of excursion without bottoming out.

Don't Trust Us...Trust Our Customers Exceptional near-field subwoofer"I love the sound of small full rang speakers. You can build very complex contraptions to help them extend into the bass region, but I wanted it all - deep bass, impact, power handling, open baffle spaciousness and full range goodness. I crossed these over at 500 Hz with the tang band 4" full range on an open baffle and I am very satisfied. These are still breaking in now, but are sounding great! The face plate for this is glued to the front of a Denova 0.23 CF sealed cabinet stuffed with ~1/3 pounds of polyfil. DSP is handled with the MiniDSP 2x4HD. They aren't capable of high output at 20hz, but the math puts them at around 95dB theoretical max at 40 hz at 1 meter, which is more than enough to pound in-room in a nearfield listening arrangement. Applying a roll-off to your curve under 40Hz keeps the bass sounding full and tight, but lets you crank the volume up further"
