HOQS N216C Neo 21” LF
This driver's motor is designed with Finite Element Analysis modeling (FEA) and outfitted with a high grade temperature stable Neodymium magnet structure to produce an abundance of motor force.
Optimized for HOQS Paraflex cabinet designs but will also work in other Folded Horn subwoofers designs, Scoops, RLH/BLH, QWP, FLH, Tapped Horn, Bandpass or Reflex cabinets.
High compliance suspension with a spaced dual spider assembly to ensure precise alignment of the voice coil in the driver's magnetic gap (alternative version of this is dual silicone treated spiders.
Very high Qms value (low mechanical losses)
Durable and stiff Carbon Fiber cone.
Bumped back plate.
Ventilated voice coil former.
2000W "Nominal" power handling.
4000W "Program" power handling.
Inside-Outside wound 150mm (6") diameter Oxygen Free Copper coil on a fiberglass former.
Ventilated voice coil former.
Custom dual spider set composed of Conex fabric, treated with silicone.
Sturdy cast aluminum frame.

Parameters
Disclaimer: Thiele/Small
The Thiele/Small parameters of a loudspeaker driver are measured under specific testing conditions, which may not accurately reflect the performance of the driver in all real-world situations. These parameters are typically measured in a laboratory setting, using specialized equipment and carefully controlled test conditions.
As such, the Thiele/Small parameters should be considered as a useful starting point for designing loudspeaker systems, but they may not accurately represent the behavior of the driver in all real-world scenarios. Factors such as enclosure design, room acoustics, and amplifier characteristics can all affect the performance of a loudspeaker driver.
It is important to note that the Thiele/Small parameters are not the only consideration when selecting a driver for a particular application. Other factors, such as power handling, frequency response, and distortion characteristics, should also be taken into account when designing a loudspeaker system.
Ultimately, the best way to evaluate the performance of a loudspeaker driver is to listen to it in a real-world setting, and to compare it with other drivers under similar conditions.
