Speaker Feet

B&W HTM71 S3 comes with 4 Self-adhesive rubber feet which you can use to secure your loudspeaker on the surface that you are putting on.

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

HTM71 S3 comes with Two-piece foam port plug 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
