Cabinet type and Materials

Fluance SX6 has a Bass Reflex type cabinet. Bass Reflex type loudspeakers (aka Ported, Vented or Reflex Port) have enclosures that uses a port, hole or vent cut into the cabinet. Ported designs are generally more efficient than the Sealed designs.

Port Position

Fluance SX6 is a rear-firing port speaker so you have to make sure you leave enough space between the back of the speaker and wall or bookshelf so that it has room to breathe.

Wall Mounting

SX6 doesn't sport any built-in mounting bracket, so you need an external structure to mount it on walls.

Does the Fluance SX6 come with a Grille?

SX6 comes with grilles. The purpose of the grille is to protect the delicate driver elements from external impacts while still allowing the sound to pass as clearly as possible.

Recommended Accessories

Here is a list of accessories that we think you may need for the Fluance SX6.

  • Speaker Cable and Connectors
    • Speaker Cables with Banana Plugs: If you know the lenght of the cable you need, this is the easier option to connect your speakers with your amp.
    • Speaker Cables without Connectors: If you are not sure about the lenght or need longer than standard cables with plugs, choose this option.
    • Banana Connectors and Plugs: If you chose the cables without connectors option or already have some cable around, pick the banana plugs separately.
  • Vibration Isolators: IsoAcoustics isolators are our favorite isolators but you may find more affordable options too.
  • Acoustic Panels and Treatments: Your room is as important as your stereo equipment so acoustic treatments goes a long way in improving the overall performance.
  • Speaker Stands: Stands bring your bookshelf speakers to ideal height (rule of thumb is to have the tweeter level with your ear in your listening position), helps stability and acoustical isolation.
