The ZR8.4D is an 8" car subwoofer from the DS18 ZR series. It handles 450 watts RMS and uses dual voice coils at 4 ohms per coil, so you can wire multiple subwoofers to the final impedance your amplifier is stable at. Peak power handling is 900 watts. Mounting requires a 7.24" cutout diameter and 4.4" of mounting depth, so confirm your enclosure before installing. Pair it with a matching monoblock amplifier and a properly tuned enclosure to get the most low-frequency output.
Rated at 450 watts RMS and 900 watts peak. Behind that rating: 2" voice coil on an aluminum former wound with Copper wire, a 55 oz ferrite motor and 18mm of one-way excursion. That is what lets an 8" cone move this much air without losing control.
Dual voice coils let you wire multiple subwoofers in series or parallel to reach the final impedance your amplifier is stable at, which gives you room to grow the system later.
A 82dB sensitivity rating turns amplifier watts into audible output efficiently, so you get more usable bass from the power you already have.
This 8" subwoofer requires a 7.24" cutout diameter and 4.4" of mounting depth. Check these numbers against your enclosure before ordering: enclosure volume and tuning change the low-frequency response as much as the driver does.
