Incredibly linear frequency response characteristics, extreme high power handling while generating the lowest harmonic distortion of any comparable 18-inch trasducer wtihin its application range.
Incredibly linear frequency response characteristics, extreme high power handling while generating the lowest harmonic distortion of any comparable 18-inch trasducer wtihin its application range- The L18P400 uses a fibre loaded cone assembly along with a high excursion triple roll,constant geometry surround- A fully optimised T-pole design generate the minimum amount of flux modulation- The T-pole also features RCf Precision's spaced gap demodulation technology, progressively braking the voice coil, providing a much smoother transition for the moving mass as it reachees its maximum excursion limits-Forced air venting system- The L18P400 is ideal for use in applications where incredible power handling,long excursion and perfect control is required- Ideal for high quality professional bass reflex and bass-horn system- The transducer's low frequency extension, coupled with its extremely low generation of harmonic distortion,also makes it ideal for use within critical listening applications such as studio monitoring subwoofer system- 4'', fiberglass inside/outside copper voice coil- 2000W continuous program power handling- 97-5 dB Sensitivity- 25 Hz - 1 kHz Frequency range- Aluminum demodulation ring- Forced air ventilation and 15mm top plate for minimum power compression- Dual spider design with silicon based dampening control- Triple roll surround and corrugated straight cone geometry- Nominal Diameter: 460 mm/ 18''- Rated Impedance: 8 O- Program Power: 2000 W AES- Power handling capacity: 1000 W AES- Sensitivity: 97-5 dB- Frequency Range: 25 Hz ÷ 1000 Hz- Effective Piston Diameter: 395 / 15-6- Max Excursion Before Damage (peak to peak): 50 / 2-0- Minimum Impedance: 6-5 O- Voice Coil Diameter: 100 mm/ 4''- Voice Coil Material: Copper- Voice Coil Winding Depth: 25 mm/ 1-0''- Number of layers: 2- Kind of layer: inside / outside- Top Plate Thickness: 15 mm/ 0-6''- Cone Material: No pressed pulp- Cone Design: Straight- Surround Material: Polycotton- Surround Design: Triple roll- Thiele/Small Parameters:- Resonance frequency: 29 Hz- DC resistance: 5-1O- Mechanical factor: 7-6- Electrical factor: 0-29- Total factor: 0-28- BL Factor: 24-6 T · m- Effective Moving Mass: 200 g- Equivalent Cas air load: 340 liters- Effettive piston area: 0-122 m²- Max- linear excursion (mathematical): 8-8 mm- Voice - coil inductance 1kHz: 2-5 mH- Half-space efficiency: 2-63%- Mounting information:- Overall Diameter: 465 mm/ 18-3''- Bolt Circle Diameter: 442 mm - 447 mm/ 17-4'' - 17-6''- Bolt Hole Diameter: 6-5 mm/ 0-25''- Front Mount Baffle Cut-out: 424 mm/ 16-7''- Rear Mount Baffle Cut-out: 424 mm/ 16-7''- Depth: 205 mm/ 8-1''- Volume occupied by the driver: 6-0 / 0-21 liters/ft³- SKU: TBALL10554
