B&W Tweeter Removal (600 Series)

Removing a tweeter from a B&W speaker without damaging it can be a tricky job. In some B&W speakers, the tweeter is secured to the cabinet with screws, and then a metal grille and trim ring are placed on the tweeter. When assembling the speaker, these are simply 'pressed' into place. Removing these parts without damaging them is more difficult. B&W therefore supplies a special tool with article number MM09989. This special tool makes removing the grille and trim ring a lot easier.

In this manual, we explain how to use this tool to remove a tweeter from the speaker cabinet of a 600 Series speaker (2018 and later). This tool can be used with the following B&W speaker series:

All these speakers contain tweeter HF01716.

The special tool MM09989 has two functions. First, with the 'lip' on one side the tweeter trim ring can be removed (photo below: left). In addition, the tool can be used to remove the metal grille of the tweeter with the magnet in the tool (photo below: right).

In order to remove the tweeter from the speaker cabinet, the trim ring must be removed. The trim ring is connected to the tweeter with five pins. In order to remove the trim ring without damaging it, the 'lip' of the special tool must be placed in the recess of the trim ring. Then use the special tool as a lever and carefully push the trim ring upwards. As soon as the trim ring comes loose, the trim ring can be lifted with your fingers. Once the trim ring is removed, you can access the screws that secure the tweeter to the speaker cabinet and remove the tweeter. There's no need to remove the metal grille from the tweeter.

The photo below shows the recess in which the 'lip' is placed. In all cases this is located at the '12 o'clock position' of the tweeter.

If desired, the metal grille can also be removed. However, we advise against this. The tweeter dome will then become very vulnerable.

Do the following at your own risk:

To remove the grille, use the magnet in the special tool. If you do not have the special tool, you can also use another magnet, provided it is strong enough.

The correct placement of the magnet on the metal grille is very important. The photo below shows the tweeter of the B&W HTM6 S2 Anniversary Edition (but all tweeters in the 600 series (2018) and the 600 S2 AE series (2020) are identical). The tweeter is still in the speaker cabinet and the grille and trim ring are still attached to the tweeter.

Place the magnet at the '6 o'clock' position at the bottom of the grille (green arrow). Then carefully lift the grille by the magnet so that the bottom of the grille rises as shown in the photo. The grille must 'hinge' at the top (red circle). This is where the grille is most firmly attached to the tweeter.

This is a close-up of the tweeter without the trim, but with the grille. The green arrow at the bottom shows where the magnet should be placed.

At the top, in the red circle, the grille is firmly attached to the tweeter. By lifting the grille at the bottom by the magnet and 'opening it like the hood of a car', the grille can be removed undamaged.
