Infinity - Two Pairs of KAPPA-86CFX Kappa 6X8/5X7 Inch Two-Way Coaxial Speakers

Infinity’s glass fiber woofer cones are lighter and stiffer with more cone-area than the competition , delivering increased low-frequency output and higher efficiency..
Edge-driven textile dome tweeters - These are not commonly used W-domes, but edge-driven textile dome speakers that will deliver broader and smoother high frequency response..
High output 2.5 ohm ohm architecture with low impedance voice coils enables the speaker to extract every watt from the amplifier and deliver peak power with ease..
Infinity speakers have to undergo a testing process that would destroy lesser speakers. Infinity freezes them, bakes them, shakes them, blasts them with ultraviolet light and drives them at full power for days at a time..
Infinity is in the business of designing reference quality speakers, and Kappa car audio speakers are no exception..

The connector outer diameter is 9.5 mm,Can Installed 3* 120x120mm fan.
Suitable for water-cooled computer CPU, industrial variable frequency drives, the laser head cooling, air conditioning evaporator and industrial control cabinet cooling.

The TL072 JFET-input operational amplifiers incorporate well-matched, high-voltage JFET and bipolar transistors in a monolithic integrated circuit. The devices feature high slew rates, low-input bias and offset currents, and low offset-voltage temperature coefficient..
Low Power Consumption, Wide Common-Mode and Differential Voltage Ranges, Low Input Bias and Offset Currents.
Output Short-Circuit Protection, Low Total Harmonic Distortion: 0.003% (Typical), Low Noise Vn = 18 nV/√Hz (Typical) at f = 1 kHz.
High-Input Impedance: JFET Input Stage, Internal Frequency Compensation, Latch-Up-Free Operation.
High Slew Rate: 13 V/µs (Typical), Common-Mode Input Voltage Range Includes VCC+, Example Applications: Motor Integrated Systems: UPS, Drives and Control Solutions: AC Inverter and VF Drives, Renewables: Solar Inverters, Pro Audio Mixers, DLP Front Projection System, Oscilloscopes.

A built-in Bluetooth receiver allows wireless music streaming from a mobile device or computer.
The internal 1000W Class-D power amplifier drives the 15" woofer and 1.5" high-frequency titanium compression driver, which combine for a frequency response of 55 Hz to 18 kHz, and a maximum SPL of 127 dB.
This bundle comes with a SS-4420 Steel Speaker Stand from Auray is built for durability and it can support speakers weighing up to 100 pounds.
Plus a Speaker Stand Bag from Auray is a spacious, durable bag designed to hold and protect two speaker stands, six microphone stands, or miscellaneous hardware for DJs, bands, and engineers between gigs, parties, and special events. Also with 10" XLR-XLR Cable.
Comes in pair is a compact and versatile 15" 2-way 1000W Bluetooth-enabled powered loudspeaker featuring custom engineered drivers in a rugged enclosure, well suited for rental houses, mobile entertainers, stage monitors, and more.
