PURIFI is a fresh company that designs and manufactures extremely high-performance transducers and amplifier modules. Don’t let the freshness fool you; their leadership team consists out of some well-respected audio technology pioneers. PURIFI developed a deep understanding of many performances degrading aspects for both amplifiers and transducers. Besides this 8 ohm version, there is also a 4-ohm version, the PTT6.5M04-NFA-01, and a 6,5″ passive radiator available.
Specifications
| Article number | PTT6.5M08-NFA-01 |
| EAN | 8785256844579 |
| Woofer Type | Ultra Low Distortion Midrange |
| Nominal Diameter | 6.5" |
| Power Handling (RMS) | 200 Watts |
| Impedance (Z) | 8 Ohms |
| Sensitivity (SPL at 1m / 2.83V) | 91 dB |
| DC Resistance (Re) | 6.5 Ω |
| Resonant Frequency (Fs) | 57 Hz |
| Electromagnetic Q (Qes) | 0.42 |
| Total Q (Qts) | 0.38 |
| Diaphragm Mass Inc. Airload (Mms) | 17.0 g |
| Mechanical Compliance of Suspension (Cms) | 0.46 mm/N |
| Surface Area of Cone (Sd) | 133 cm2 |
| BL Product (BL) | 9.7 N/A |
| Compliance Equivalent Volume (Vas) | 12 L |
| Maximum Linear Excursion (Xmax) | 3.9 mm |
| Driver's Mechanical Losses (Rms) | 1.44 kg/s |
| Cone / Diaphragm Material | Proprietary Fibre Mix |
| The mechanism | Improvement |
| Low force factor modulation | Current through the voice coil is not distorted by cone movement. Gives undistorted midrange regardless of the excursion |
| Constant force factor over excursion – Bl(x) | Prevents amplitude devotions of midrange output during the large excursion (sometimes called ‘burbling’) |
| Low surround radiation distortion | Reduces harmonic and intermodulation distortion caused by surround |
| Low magnetic hysteria distortion | Reduces harmonic and intermodulation distortion caused by magnetic traces left by the previous cycle |
