Compact 6th-Order Bandpass Design
12" Long-Excursion Driver
The 12" long-excursion cone driver provides powerful, controlled bass. The long-excursion design maximizes cone movement for increased sound pressure.
6th-Order Bandpass Enclosure
The 6th-order bandpass design provides a frequency response concentrated in the low-frequency range. The 6th-order bandpass is ideal for PA and entertainment.
2000W Peak Power
Efficient Class D Amplifier
The 2000W peak Class D amplifier provides efficient power with low energy consumption. 2000W of power is sufficient for most professional applications.
Advanced Thermal Management
The low-noise variable-speed fan provides efficient cooling. Advanced cooling ensures reliable operation.
Controlled Frequency Response
41Hz - 108Hz at -6dB
The frequency response of 41-108Hz at -6dB provides deep, controlled bass. The controlled response is ideal for PA and entertainment.
Extension to 38-121Hz at -10dB
The extension to 38-121Hz at -10dB provides low-frequency extension. Extension is important for full-range reproduction.
Maximum SPL of 128dB
Powerful Sound Pressure
The maximum SPL of 128dB measured on-axis at 1m provides very powerful sound pressure. 128dB SPL is sufficient for most professional applications.
Intrinsic Correction™ DSP
Intrinsic Sound Correction
Intrinsic Correction™ DSP provides automatic sound correction and loudspeaker management. Intrinsic correction optimizes frequency response.
Loudspeaker Protection
Intrinsic correction protects the loudspeaker from overload and damage. Protection is important for durability.
Professional Portable Construction
Birch Plywood Enclosure
The 15mm birch plywood enclosure provides rigidity and durability. Birch wood is both sturdy and lightweight.
4 Heavy-Duty Rubber Casters
The 4 low-noise heavy-duty rubber casters facilitate transport. Casters are ideal for portable applications.
Dual M20 Pole Receptacles
The dual M20 receptacles allow for a secure, wiggle-free connection to a speaker pole. Dual receptacles allow for vertical or horizontal deployment.
Flexible Controls
Rotary Gain Control
The rotary gain control allows for precise level adjustment. Rotary control is essential for audio mixing.
Selection Buttons
The 2x selection buttons allow for function control. The buttons facilitate operation.
Professional Inputs
2x XLR Combo Inputs
The 2x XLR combo inputs allow for flexible connection. Combo inputs are standard on professional equipment.
2x XLR Loop-Thru Outputs
The 2x XLR loop-thru outputs allow for daisy-chaining subwoofers. The outputs allow connection to additional systems.
