To start off this look at the Martin Logan Dynamo 700w Subwoofer is a photo of the subwoofer with its included accessories and documentation.

Starting in the center is the actual Dynamo 700w shown in its down-firing configuration.

Moving to the left is an accessory speaker grill that can be used to cover the subwoofer driver cone if the subwoofer is used in it front-firing configuration.

Moving to the top is an included wireless transmitter (SWT-2) and detachable power supply. Also shown are additional accessory RCA connection adapters and removable spike feet. Underneath the transmitter and other accessories are illustrated user guide and product registration card.

Finally, just to the right of the subwoofer is the detachable power cord.

The Dynamo 700w is a compact subwoofer that features a 10-inch driver, supported by a 300-watt continuous power-capable amplifier. The 700w also has a built-in wireless receiver that can be used directly with the Martin Logan Motion Vision Sound Bar or in conjunction with the included SWT-2 wireless transmitter connected to ​any home theater receiver that has a subwoofer or line audio preamp outputs. The Dynamo 700w also provides direct wired RCA LFE or Stereo Line-in connections.

In addition, for flexible setup, the Dynamo 700w can be configured for either a front-firing or down-firing orientation via the included removable corner feet.

Here is a four-way look at the Martin Logan Dynamo 700w Subwoofer showing two front, rear, and bottom views.

Starting on the top left, the first photo shows front of the subwoofer as configured for down-firing operation (in other words, the subwoofer driver is on the bottom). The top right photo shows the rear of the subwoofer (once again, as it looks when the subwoofer is configured for down-firing operation).

Moving down to the bottom left is ​a look at the 10-inch subwoofer cone, and subwoofer feet when configured for down-firing operation, while the final bottom right photo shows what the subwoofer looks like when it is configured for front firing operation. Here, the feet have been moved so that the connections and control shown in the top right photo are now facing down, and the speaker grill is attached to cover the subwoofer speaker cone.

NOTE: When configured for down-firing operation, care needs be taken when lifting or moving the subwoofer so as not to damage the driver cone.

Here is a look at the controls and connections provided on the Martin Logan Dynamo 700w Subwoofer.

Starting on the left side of the photo are:

Level (AKA Gain or Volume) Adjusts volume level of the subwoofer. My suggestion is to set this level at a fixed point and use your receiver's level controls to set the relative volume in relation to the other speakers in your system via the receiver's master volume control.

Phase Control: 0 or 180 degrees (synchronizes in-out motion of sub speaker with in-out motion of other speakers in system).

Crossover Switch: The Bypass setting allows the use of the subwoofer crossover settings that may be available on a connected home theater receiver or audio processor. The Variable setting allows the use of the Low Pass Filter (Crossover) adjustments available on the Dynamo 700w.

Low Pass Filter: Allows the setting of the Dynamo 700w's crossover point when the crossover switch set to Variable.

Line Level Input: LFE or Stereo Line-in inputs for use when using a wired connection between the LFE or Subwoofer Preamp output of a home theater receiver and the Dynamo 700w.

Moving to the far right are the Wireless Status LED indicator and Synch Button. When setting up the Dynamo 700w, you press the Sync button until the LED indicator emits a steady light.
