Input Type

BW 603 has Post type connectors and lets bi-amping/bi-wiring. Bi-wiring can enhance the overall transparency of your loudspeakers by using separate speaker wires for the low and high-frequency drivers from a single amplifier. Bi-amping, on the other hand, involves using separate amplifiers for the high and low-frequency drivers, potentially resulting in a greater dynamic range and reduced distortion.

Cabinet type and Materials

B&W 603 has a Bass Reflex type cabinet and a MDF/Vinyl finish. 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.

Speaker Feet

  • Plinth (base)
  • 4 Rubber feet
  • 4 Spike feet

It is always recommended to use some kind of feet under all types of speakers. Besides limiting the movement of the speakers, it also compensates for non-flat surfaces and limits the contact surface area of the speaker. Rubber based feet also help isolating the vibrations within certain frequency ranges.

Port Position

B&W 603 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. BW 603 comes with 2 Two-piece foam port plugs so if you don't have any choice but place the speakers too close to the walls or other surfaces, you can use these plugs in order to avoid boomy or too much bass.

Available colors

B&W 603 is available in Black, White and Oak.

Recommended Accessories

Here is a list of accessories that we think you may need for the Bowers & Wilkins 603.

  • 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.
