Test Bench: The PTT6.5M08-NFA-01 6.5" Midrange from Purifi Audio

The PTT6.5M08-NFA-01 6.5" Midrange is the fourth woofer from Purifi Audio to be examined in Test Bench. This midrange is pretty much identical to the previously examined PTT6.5X and PTT4.0X woofers, and includes the same constant Sd surround, cone edge stiffening ring, and low magnetic hysteresis motor design. However, the PTT6.5M08-NFA-01 is optimized to have higher efficiency (91dB at 2.83V8/1m) for use with multiple woofer three-way design configurations.

The cooling for the 6CXN36 is exclusively provided by the motor mass, which is substantial, and no vents are required for the impressive 200W continuous power handling rating in a small diameter driver such as this.
