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 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.

Small to medium sized speakers are usually lower power designs. The power rating is given in the technical data for each audio driver. For a reliable long service life, please operate your new speakers with care. For the first 100 hours, operate them at very low volumes. After this period, gradually increase the volume to a normal listening level. If you see the cone of the speakers making large movements, immediately turn the volume down. This will protect the speaker and your human hearing from damage. Factory mechanical defects for a period of 1 year. Excessive hard use (over-driving) and other damage caused during customer use is excluded from our warranty.
