    READY TO SAFELY PACK AND SHIP!!! CHECK OUT PROFILE FOR OTHER SIMILAR RELATED ITEMS AND MORE!!! Building on the success of the original Dynamo, our designers went on to create the compact, powerful Dynamo 700w, with WIRELESS INCLUDED. Featuring a high-current 300-watt RMS, 600-watt peak amplifier and 10-inch cone driver, the Dynamo 700w delivers deep, tight, effortless bass for home theater or stereo music. Its standard down-firing configuration quickly (and easily!) converts into a front-firing setup for those who prefer a hidden installation. Finishing touch - an included wireless receiver for bass aficionados who prefer a clean, minimalist look in the room, no cables in sight. Does Not Come with power chord. See photos for any minimal visible scratch, wear, smudge, etc not impeding overall functionality of item Selling as is. Have not encountered any issues or limitations during usage or testing performance. Step Up to Low Frequency Accuracy, Power, and Deeper Bass!Building on the success of the original Dynamo, our designers went on to create the compact, powerful Dynamo 700w. Featuring a high-current 300-watt RMS, 600-watt peak amplifier and 10-inch cone driver, the Dynamo 700w delivers deep, tight, effortless bass for home theater or stereo music. Its standard down-firing configuration quickly (and easily!) converts into a front-firing setup for those who prefer a hidden installation. Finishing touch - an included wireless transmitter and receiver for bass aficionados who prefer a clean, minimalist look in the room, with no cables in sight.Built-In Wireless Receiver offers Extreme Placement Flexibility!Although correct placement plays a key role in optimizing subwoofer performance, sometimes it imposes the inconvenience (not to mention unsightliness!) of running long lengths of cable through walls, along baseboards or under floors and carpets. To solve the problem, the Dynamo 700w incorporates a wireless receiver (digital RF transmission) for use with the included SWT-2 MartinLogan Subwoofer Wireless Transmitter in which case, cable clutter also becomes a moot point!High-Resolution Low-Distortion 10-Inch WooferThe Dynamo 700s advanced-technology driver pairs a high-power magnet structure with a 10-inch diaphragm to deliver huge excursion and sound output while perfectly preserving the tiniest bass detail... and all without a hint of distortion. The exceptional damping properties of the cone material also ensure the smooth, non-resonant response necessary for truly seamless blending with MartinLogan electrostatic panel and Folded Motion™ driver technologies.Advanced Ultra-Efficient 300-Watt AmplifierThe Dynamo 700ws ultra-efficient high-power amplifier uses variable audio tracking power supplies to drive its class AB output stage. With lower distortion and less noise than typical Class D switching amplifiers this advanced design allows the amplifier to operate at much higher efficiencies than a typical class AB amplifier, delivering a true 300 watts of continuous power. An energy-conscious design, the Dynamo 700ws amp consumes less than a single watt in Standby mode.Front-Firing or Down-Firing ConfigurationTo maximize performance when installed inside of a cabinet or other discrete installation, the Dynamo 700ws standard down-firing configuration easily converts into a front-firing orientation-no tools required! A grill cover and 90 degree RCA adaptors are provided for use in front-firing applications.Inverse Mathematical Equalization (IME) FilterAn IME filter is derived from the inverse of the unfiltered driver response. Precision IME filtering yields extremely accurate low-frequency response - far superior to that provided by the simple second-order high-Q filters typically found in subwoofers in this price range.Sealed Cabinet with Extensive Internal BracingA good sealed system will typically exhibit less transient-blurring group delay while maintaining smooth, consistent response regardless of music or movie source material. On the outside, the Dynamo 700ws cabinet is constructed from the finest composite material for acoustic integrity. Inside, critically placed structural cross-bracing acts an excellent baffle for the woofer while the added rigidity keeps cabinet-induced resonances and non-linearities to inaudible levels.Inverse Mathematical Equalization (IME) FilterAn IME filter is derived from the inverse of the unfiltered driver response. Precision IME filtering yields extremely accurate low-frequency response - far superior to that provided by the simple second-order high-Q filters typically found in subwoofers in this price range.Seamless System Integration - Engineered for Stereo and Home TheaterComprehensive connection options, low-pass filtering and phase control make integrating the Dynamo 700w subwoofer into a multi-channel home theater or stereo music setup simple and seamless. The main left/right line-level inputs feed into a precision low-pass filter with a cut-off frequency variable from 35 to 120 Hz. For systems in which a surround processor supplies the crossover, the Dynamo 700w offers an LFE input that bypasses its internal filters.Energy Transfer Coupler (ETC) SpikesThe Dynamo 700w comes with custom ETC spikes which can be used in place of the feet to enhance stability on thick carpets, or create tighter coupling between subwoofer and floor to enhance overall sound quality.
