This listing is for a pre-owned MartinLogan Dynamo 1000W 12” Subwoofer in excellent condition that comes with the power cable and a copy of the manual as seen pictured. This subwoofer measures (L x W x H): 13 3/4 x 14 1/8 x 15 1/4 and weighs 36 lbs. 10 oz. Introducing true high-end performance , with built in wireless! Home friendly aesthetics and power, lots of power! In a nutshell, thats the incredible Dynamo 1000w subwoofer. Dramatic bass detail and bass attack, superb extension and room-shaking output ensure a music and home theater experience like no other subwoofer in its class can deliver. Features include a 500-watt RMS, 1,000 watt peak amplifier and 12 cone driver. Its standard down-firing configuration quickly (and easily) converts into a front-firing configuration, ideal for discrete installations. Finishing touch.......an optional wireless receiver for a cable-less environment.Powerful Dynamo Subwoofer... Ideal for Larger Rooms! True high-end performance. Home-friendly aesthetics. And power, lots of power! In a nutshell, thats the incredible Dynamo 1000w subwoofer. Dramatic bass detail, bass attack, superb extension and room-shaking output ensure a music and home theater experience like no other subwoofer in its class can deliver. Features include a 500-watt RMS, 1,000-watt peak amplifier and 12-inch cone driver. Its standard down-firing configuration quickly (and easily!) converts into a front-firing configuration, ideal for discrete installations. Finishing touch... an included wireless transmitter and receiver for a cable-less environment. 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 1000w incorporates a wireless receiver (digital RF transmission) for use with the optional SWT-2 MartinLogan Subwoofer Wireless Transmitter in which case, cable clutter also becomes a moot point!High-Resolution Low-Distortion 12-Inch Woofer The Dynamo 1000ws advanced-technology driver pairs a high-power magnet structure with a 12-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 500-Watt Amplifier The Dynamo 1000ws 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 500 watts of continuous power. An energy-conscious design, the Dynamo 1000ws amp consumes less than a single watt in Standby mode. Front-Firing or Down-Firing Configuration To maximize performance when installed inside of a cabinet or other discrete installation, the Dynamo 1000ws 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) Filter An 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 Bracing A 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 1000ws 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.Seamless System Integration - Engineered for Stereo and Home Theater Comprehensive connection options, low-pass filtering and phase control make integrating the Dynamo 1000w 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 1000w offers an LFE input that bypasses its internal filters.

Selling our home theater pair of Dynamo1000 powered wireless or wired connection subs. Cool thing is that the feet can be moved to make them front or down firing depending on your chose plus they come with carpet spikes or remove them . Nothing wrong with them at all.

Selling a MartinLogan Dynamo 800X subwoofer with 10 down firing driver and 600 peak watts. The subwoofer was briefly used for a few hours in one of our systems while testing some speaker setups. It is in excellent condition and working perfectly. Includes grill for optional conversion to front firing (legs are removable), power cord, and instructions. Ships double boxed in non-original packaging. Deep, musical bass from MartinLoganMartinLogans Dynamo 800X packs surprisingly punchy bass and lots of innovative features into its compact enclosure. Hard-hitting lows come courtesy of a high-excursion 10 woofer powered by a 300-watt amplifier. And just like other models in MartinLogans new 2018 Dynamo lineup, this sub has some cool app-based conveniences that make it easier than ever to set up and adjust.Anthem Room Correction (ARC) automatically fixes room acoustics problemsDownload the free ARC Mobile app to your iOS® or Android™ phone or tablet. Your device takes bass measurements using its built-in microphone, analyzes the signal to find acoustic irregularities, and automatically applies correction. The result? Smooth, well-balanced bass thats tailored to your specific room, furnishings, and audio system.A handy Bluetooth® control appOnce you get the Dynamo 800X placed in your room, youre not likely to have to strain to reach its back-panel controls — it actually has relatively few of those. Instead, youll use MartinLogans Subwoofer Control app, which connects the sub to your phone via Bluetooth, so you can make any necessary adjustments from the comfort of your favorite listening seat. That includes volume and preset EQ curves, as well as tweakier adjustments like phase and crossover.Flexible design featuresThe Dynamo 800X comes set up from the factory with its woofer facing downward. But if youre installing it in an enclosed cabinet you might want to make that woofer face forward instead. The subs clever design lets you easily switch the placement of its isolation feet to make the woofer front-firing. It even comes with a grille to cover the woofer in this configuration.If youre placing the sub on thick carpeting, you can remove the rubber feet to expose built-in ETC™ (Energy Transfer Coupler) spikes, which help stabilize the sub and give you potentially tighter-sounding bass.Want to make it wireless?Add MartinLogans optional SWT-X wireless transmitter/receiver system to lose the signal cables entirely. The kits receiver plugs directly into a port on the back of the subwoofer. (Remember, youll still need to plug this baby into an AC outlet.)READ LESSProduct highlights:frequency response: 24-200 Hz (±3dB)built-in amplifier delivers 300 watts of continuous power (600 watts peak)10 high-excursion polypropylene woofer with an inverted surround and cast aluminum basketsealed (acoustic suspension) cabinet with down-firing woofer design converts easily to front-firingcompatible with Anthem Room Correction (ARC) Mobile app for room optimization using your devices built-in mic, or an optional calibrated microphonefree MartinLogan Subwoofer Control app for iOS® and Android™ for easy setup and configurationcontinuously variable low-pass 35-120 Hz crossover (app only)continuously variable phase control (app only)3 preset listening modes: Music, Night, and Movie (app only)level control (app or rear-panel knob)auto on/off switch on back panelleft/right and LFE RCA line-level inputsspeaker-level inputs12-volt trigger input for custom automation setupscompatible with optional MartinLogan SWT-X wireless connection kit for more placement flexibilityincluded Energy Transfer Coupler (ETC) spikes can be used for tighter coupling between subwoofer and floor to enhance sound qualitysatin black finish12-7/16W x 13-3/4H x 13-1/8D (down-firing); 12-7/16W x 14-5/8H x 12-3/4D (front-firing)weight: 30 lbs.
