XL Subwoofers

Raven 10-Inch & 12-Inch XL Subwoofers

xlsubs

The Raven XL Subwoofers (Designed by ORCA · Made in California) set the bar for superior subwoofer power.

The Raven 10XL subwoofer is designed to produce very deep bass at realistic levels in a remarkably compact cabinet with extremely low distortion, minimum compression and fast transient response. We recommend typically 1 cuft sealed enclosure ( F3 = 42 Hz), or 3 cuft vented enclosure (F3 = 22 Hz). The Qts and rugged suspension make it also quite ideal for use in a transmission line.

The Raven 10XL is made in California, USA.

MAGNETIC MOTOR
  • It allows a +/-18 mm linear Xmax for extremely low distortion and high power handling.
  • The lightweight compact neodymium motor is a patented XBL design with two magnetic gaps and three Faraday rings to minimize inductance, flux modulation and intermodulation distortion.
  • The BL and inductance curves have a flat top to minimize 2nd and 3rd harmonic distortion and to optimize the impulse response. The audible result is explosive, uncompressed, dynamic.
EMISSIVE AREA

Cone and dust cap are made made of a woven carbon mat laminated to a high modulus paper so they are extremely rigid and highly damped, thus a very smooth frequency response up to 1500 Hz!

SUSPENSION

A 25 mm wide rubber surround is used for long life even under high excursions.

FRAME

A stiff cast aluminum basket is used for best sound quality and good cooling.

COOLING

The voice coil is directly cooled through radial holes on the motor so that cool air flow does not get restricted by box stuffing. Additional air vents through the cone itself help further to equalize pressure in front and back of the cone.

AMPLIFIER TO USE
  • It takes 800 W @ 1% THD into 4 Ω to reach Xmax
  • So we recommend a power amplifier of high quality of minimum 800 W and maximum 1600 W to get the most out of this exceptional drive unit.
