  • Audio
    • Minimum Frequency Response: 30 hertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The minimum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
    • Maximum Frequency Response: 200 kilohertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The maximum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
    • Amplifier Class: D (An amplifier's mode of operation, specifically the conditions in which its electrical current flows for the duration of an audio signal, determines its class. Each class has its strengths and weaknesses when it comes to power efficiency, levels of crossover distortion, and overall sound quality.)
    • Enclosure Type: Bass reflex
    • Firing Direction: Down
    • Speaker Type: Floorstanding
    • Subwoofer Type: Powered (Passive subwoofers require an external amplifier, such as the one driving the main speakers in the system, for power. Active subwoofers, on the other hand, have a designated amplifier (one that isn't shared with other speakers) for power as well as line-level crossover.)
    • Enclosed: true
    • Peak Power Handling: 150 watts (The maximum amount of power an electronic device, like a speaker, can handle without damage. This refers to short bursts of power, while root mean square (RMS) power handling indicates the amount of continuous power a device can sustain. Higher levels of distortion can also occur at peak power levels when the device is powered beyond its recommended usage.)

Speaker Buying Guide

  • Integrated Class D Amplifier: Dynamo 400’s Class D amplifier supplies 150W peak power (75W RMS) and operates with extremely low levels of distortion to deliver dynamic impact with plenty of overhead.
  • Low Pass Filter and Phase Adjustment: Properly calibrate the subwoofer for seamless integration into any system.
  • Inputs: Dynamo 400 features Stereo RCA Inputs, a RCA LFE Input and speaker level inputs for maximum flexibility.
  • Low-Turbulence Port: Dynamo 400 features tuned, long low-turbulence ports designed to provide superb low-end extension while minimizing port induced distortion.
  • Inverse Mathematical Equation (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.
