HelloWe have a number of these brand new high quality drivers from PHL in France, made for NEXO loudspeakers. These are ideal for making a compact high performance 2 way loudspeaker, and with their 2 voice coil, you can send them some serious power without noticing any compression or distortion.This is for a pair of loudspeakersI can send you the full tech sheet upon request.We can export worldwide at competitive rates. Please let us know where you are and we will get back to you with a shipping quote. Please feel free to contact us with any questions you may have.We accept returns as long as the drivers are sent back in their original packaging, in perfect cosmetic and working order. Applications- These 6.5”ultimate sounding quality Bass-Midrange drivers have been designed to match advanced studio monitoring requirements for proximity monitoring- The exceptional sound accuracy of these units results from a careful design using A/B listening tests to select technological solutions- It is this which authorizes their use up to 2.5kHz without any compromise, and up to 4.0kHz with full preservation of dynamic behavior (Compromise is on directivity pattern only)- Optimum Bass-Reflex loading is situated between 12L and 16Ltuned from 45Hz to 40HzDesign ConceptDeflection Controlled Diaphram- Optimized for dynamic damping- Deflection Controlled Diaphragm technology consists in optimizing the shape and material of the diaphragm so that it works as a mechanical transmission line, to avoid breaking modes as well as mechanical threshold which destroy sound quality- It is this leading edge technology which offers substantial sonic advantages- Those advantages include sound coherency, fast transients, stable sound imaging, high sensitivity, wide frequency range and reduced directivity patternSoft Excursion Limiting- The Soft Excursion Limiting mechanism is a special S-profile design of the rubber surround avoiding voice-coil bottoming which destroys driver functionality instantaneously- The cone excursion is progressively limited to +/- 8mm, introducing a soft clipping which totally protects loudspeakers from over-excursion damageCompact Magnet System- Its design has been specially optimized to obtain maximum transducing efficiency while avoiding unlinear behaviour such as coil inductance variation with position, flux modulation, harmonic distortion, rest position offset, air compression and off-axis voice-coil pushing- Its design incorporates a T-shaped pole piece and a flux stabilization ring- It also takes into consideration demagnetization at cold temperaturesIntercooler System- Entirely integrated into the loudspeaker itself, the Intercooler System extracts the heat produced by the Joule effect in the voice-coil- It does so via an air flow directed through the heatsink rims of the basket by the motion of the dust-cap and the spider- The gain brought about by this technology is over 20% of extra power, so for example, a 3 coil according to this design has the same power handling capacity as a classical 4 oneFeatures- Power handling capacity - 150W AES- Reference Efficiency (1W @ 1m) - 92 dB SPL- SPL max (continuous) - 110 dB SPL- Usable frequency range - 50-4000 Hz- Environmental withstanding - Outdoor?- Impedance: 16 OhmsArchitectural Specifications- Nominal Diameter - 166mm- Frame - High tensile alloy pressure die-cast basket with patented Intercooler System- Magnet System - 2 highly energized, heat extracting design with flux stabilizing ring- Voice Coil - High-temperature stabilized copper-clad aluminium ribbon wound on vented high-strength glass polyimide- Cone Assembly - High-strength cellulose fiber cone impregnated and coated on both sides with damped resins, fitted with fabric dome, high-speed flat, damped surround and acoustically damped rear cavity- Speaker Mass - 2.15kg
