What makes the Velodyne DD-18 subwoofer so good?
What makes the Velodyne DD-18 subwoofer so good?
Position determined on test at setup time. The DD–18 is a big sub that delivers truly big sub sound. It does so with a driver packed with performance-enhancing features, as well as a sophisticated digital drive control system. In every way that is important, the DD – 18 excels, making it a benchmark product in every category.
What’s the price of a Velodyne digital drive DD-18?
When Curt Chisholm, the company’s head of customer support, offered me the Digital Drive DD-18 to review, I jumped at the chance. The DD-18 physically resembles Velodyne’s HGS-18 ($3499).
How does room compensation work on a Velodyne DD-18 +?
Velodyne’s DD-18+ now takes the technology a step further with the addition of automated room compensation. While the sub’s internal circuitry can adjust automatically, it also offers manually adjusted, menu-driven equalization that graphs any room-response changes in the DD-18+’s output on a computer screen in real time.
How does a DD-18 subwoofer work in a room?
To calibrate the DD-18 in the user’s room, the subwoofer generates a swept tone that is detected by the microphone. The mike “listens” to the sub’s output only at the specific frequency of the sweep generator’s tone, this allowing it minimize the effects of room modes.
Is the Velodyne digital drive DD-18 powered subwoofer?
Velodyne Digital Drive DD-18 powered subwoofer It’s common to read ads for new audio hardware that crow about “revolutionary” breakthroughs in sound performance, and that’s how Velodyne crowed about their new Digital Drive DD-18, servo-controlled, powered 18″ subwoofer.
To calibrate the DD-18 in the user’s room, the subwoofer generates a swept tone that is detected by the microphone. The mike “listens” to the sub’s output only at the specific frequency of the sweep generator’s tone, this allowing it minimize the effects of room modes.
How does the DD-18 high gain servo system work?
The DD-18’s High Gain Servo system uses a new voice-coil-mounted accelerometer. An ADC chip digitizes the control signal at the woofer cone, reducing noise in the servo loop system.
What kind of Eq does a Velodyne subwoofer use?
The subwoofer uses a Windows software interface, via USB, for setting the room EQ, and the bench test results are the best I have ever seen from Velodyne. Outputs: Line-Level (XLR and RCA), Thru Output (No High or Low-Pass Applied), High-Pass, Ethernet, S-Video, RS-232 The first thing one will notice in looking at the DD-18+ is its shape.
