ADVANCED ULTRA-EFFICIENT SWITCH MODE POWER SUPPLIES AND CLASS-D AMPLIFIERS

Dynamo subwoofer class-D amplifiers operate with extremely low levels of distortion and deliver dynamic impact with plenty of overhead. Low- noise, high-power switching power supplies produce clean power efficiently in a small space and effortlessly provide tremendous levels of current. Both feature high-quality MOSFET transistors, transformers, noise-suppression networks, and control circuitry. The switching power supply combined with reliable class-D technology means there’s virtually no energy lost in the subwoofer system.

INVERSE MATHEMATICAL EQUALIZATION (IME) FILTER

The IME filter used in the Dynamo subwoofers is derived from the inverse of the unfiltered driver response. Precision IME filtering yields extremely accurate low-frequency response—superior to that provided by the simple second-order high-Q filters typically found in subwoofers in this price range.

LOW-TURBULANCE PORTS

When properly optimized and executed, ports are a convenient, cost- effective way to increase low-frequency output. Dynamo 400 and 600X feature tuned, long low-turbulence ports designed to provide superb low-end extension while minimizing port induced distortion.

LEFT AND RIGHT 2-CHANNEL INPUTS

Dynamo 400, 600X, 800X, 1100X, and 1600X subwoofers feature left and right input via RCA line level as well as speaker level connections.

LFE HOME THEATER INPUT

Dynamo 400 and 600X’s right inputs double as an LFE input for home theater applications. Dynamo 800X ups the ante by adding a discrete LFE RCA line level input. Dynamo 1100X and 1600X go one step further by adding both XLR and RCA inputs for LFE connection.
