JBL / Selenium D3505TI-ND-DPD: 2" Neodymium Titanium Horn Driver

Intended for high output / low distortion professional applications, the JBL / Selenium D3505TI-ND-DPD 2" exit Compression Driver features a high flux density Neodymium magnetic assembly through copper shorting ring.  This motor design reduces distortion and minimizes the high frequency roll off caused by voice coil self inductance.  Even more compact than its sibling the D3501TI-ND, the D3505TI-ND-DPD is more than 1" shallower and features a fast expansion throat.  This carefully calculated aperture helps keep distortion low and maintains the flattest possible response to 20 kHz.  The Driver's great overall performance is also attributable to the pure Titanium diaphragm's embossed snowflake pattern and IPF (impregnated polymer fiber) surround.  An optimized aluminum injected phase plug minimizes phase cancellation, while the finned aluminum rear cover adds strength and an additional opportunity to control heat buildup The CCAW (copper clad aluminum wire) voice coil is wound on a high temperature polyamide former.  Selenium's DPD (Driver protection device) circuit utilizes a PTC and a HPCCR resistor, assuring greater reliability when the Driver is subjected to overload conditions and abuse.  A precisely engineered dome / coil structure and alignment mechanism guarantees fast, easy field repair in the rare event of a diaphragm failure.  The D3505TI-ND-DPD is recommended for use in concert touring loudspeakers, stage monitors, and other high output speaker systems.  Its small size makes it useful for the design and construction of ultra compact enclosures or line arrays.  The D3505TI-ND-DPD's 4 bolts pattern facilitates mounting on industry standard 2" throat Horns.  Power handling: 150 W (including xover, 800 hz, 12 dB / octave) voice coil diameter: 3".  Impedance: 8 ohms.  Frequency response: 500 - 20,000 hz (no crossover).  SPL: 111 dB 2.8 V / 1 m.  Magnet weight: 21.5 oz Neodymium.  Dimensions: overall diameter: 5", depth: 2.8".  Weight: 6.2 lbs.  Mounting type 4 bolts.  Exit diameter 2".  Diaphragm material Titanium.  Impedance 8 ohms.  Power handling (RMS) 150 W.
