Question 1

What are the adjustments and controls on the back panel of the B&W ASW300 and what do they do?

Accepted Answer

The B&W ASW300 does not number its adjustments, but the back panel includes several important controls:

Volume - Adjusts the sound level of the subwoofer (recommended position: 9 o'clock)
Power Switch - Turns the subwoofer on/off (Auto mode available)
Phase Selector - Adjusts the sound phase to optimize integration with your speakers
Low-pass Filter and its Switch - Sets the cutoff frequency of the filter (or disables it)
EQ Selector - Allows you to choose between EQ settings A or B

If your manual includes a numbered diagram of the back panel, refer to it for precise position identification. For optimal setup, start by setting the volume to 9 o'clock, the EQ to position A, and the low-pass filter disabled, then adjust according to your preferences.

Question 2

Why are the bass of my B&W 801D speakers not working properly?

Accepted Answer

Several causes may explain why the bass of your B&W 801D speakers are not working properly. Here are the main points to check:

1. Checking the connections

Make sure that the cables connecting your speakers to the amplifier are properly connected, without any loose contacts or polarity inversion. A poorly connected or damaged cable can lead to a loss of low frequencies.

2. Amplifier settings

Check the settings of your amplifier, especially the bass settings and any filters. A setting that is too low or an activated high-pass filter can cut off the bass.

3. Speaker positioning

The placement of the speakers in the room influences the reproduction of bass. Avoid placing them too close to walls or in a corner, as this can alter the low-frequency response. Try to move them slightly away from reflective surfaces.

4. Technical condition of the speakers

A hardware issue, such as a damaged bass speaker, can also be the cause. If possible, test the speakers on another audio system to see if the problem persists.

5. Other checks

Check that the internal fuses are not blown.
Ensure that the speakers are powered correctly, if they require external power.

By following these steps, you should be able to identify the cause of the bass malfunction on your B&W 801D and remedy it.
