Compact bass powerhouse


The two key features that stand out with the Dynamo 700W powered subwoofer is its ability to get some serious bass notes from its compact 12″ cube size and secondly, work wirelessly with with its SWT-2 transmitter. With this latter feature, you can place the subwoofer anywhere in the room without running long lengths of interconnect cables which would help you save some money. You could place the SWT-2 right next to your preamp or AV processor and connect it with a regular 1m pair of RCA cables. After that, you just need to pair with the sub and you are all set to go. The maximum wireless range is about 30-40 feet so unless you have a really large room (in which case you probably need a bigger sub!) the sub will work in any medium/small size room. You can also connect directly to the sub via its RCA inputs if you want. On board amp is a 300W unit and the frequency range of the sub is 24 – 200 Hz. The Dynamo 700W can be used with its 10″ driver firing downwards or placed on its side firing forward (grille cover is provided when used sideways).

Overall condition of the subwoofer is good. Minor scuff marks here and there but nothing major. Switch on the rear panel allows selection of for 115V or 230V use so it can be used anywhere in the World. We don’t have the original box but will securely pack this for safe shipping. Manual, grille cover and SWT-2 transmitter included.
