HOQS N123 12" MID
This driver's motor is designed with Finite Element Analysis modeling (FEA) and outfitted with high grade temperature stable neodymium material to produce an abundance of motor force.
Optimized for HOQS Paraflex Kicktop cabinet designs but will also work in other Midrange Horn cabinet designs & Mid frequency designs, or even Direct Radiating Reflex cabinets.
Weatherproof cone treatment (front)
Ventilation paths include: Ventilation between the top plate and bottom of the frame, ventilated voice coil former, ventilated pole piece, and ventilated back plate periphery.
500W "Nominal" power handling.
1000W "Program" power handling.
Inside-Outside wound 75mm (3") diameter Oxygen Free Copper coil on a fiberglass former.
Low inductance neo motor with abundant force for its class.
High compliance suspension combined with light moving mass and previously mentioned strong motor.
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.
