DESCRIPTION:
- 50mm Fullrange drive unit
- 4ohm single ferrite magnet
- 3in cone with paper, mica, glass fiber materials
- Operating range to 25KHz –very linear response
- Low-profile multiform cone –broad directivity pattern
- Long stroke suspension with progressive-rate spider
The CHN50P is an affordable compact 3 inch drive unit suitable for use in small full-range near-field projects, or as a quality mid-tweeter for low-crossover multiway designs with our CHP90, also line-array designs. The cone is formed from paper, mica and fibre-strand materials creating high stability in the emitting surface across the usable frequency range.
F Zero is 126Hz, VAS is +1.24 Litres and SPL 87.5 dB. Useable frequency range (depending on box design) is from 120Hz to 28KHz rated at +87dB in many applications. We have built a gentle rise into the low and high frequency response, as seen in some of our more expensive drive units, to enhance positioning flexibility. The sound presentation is neutral and the Thiele / Small parameters, with a generous 3.5mm (1-way mechanical) Xmax are balanced for ease of use.
The low-mass voice coil, suspension and shallow profile magnesium alloy cone are unique designs for the CHN50P. The pressed steel frame is designed to be very open and allow airflow to be as free as possible to the rear of the cone. The response extends from resonance beyond 20KHz, and the impedance rise at higher frequencies is near flat.

Pretty well designed and has a good response within its stated frequency range. I’ve been designing back-loaded horns and T-lines with single full-range drivers in stereo config., this driver pair does well although Xmax of +/- 3.5mm isn’t suitable for vented enclosures as one will face significant cone breakout at power closer to its rated 7watts.
For the selling price here they make for an excellent pair for small to medium sealed enclosures; hence my rating of 5/5
Cheers!
