I have a Mordaunt-Short MS309W and would like to replace the original driver. The problem is when the sub hits certain frequencies, I hear a clanking sound as if 2 glass bottles are hitting each other.

Does anyone have any recommendations as to what would be a fine replacement?

Specifications for the Mordaunt-Short MS309 Subwoofer:
Enclosure Type: Twin downward facing tuned ports.
Frequency Response: 35Hz to 200Hz
Power Rating: 150 watt Active
Drivers: 1 x 10" (255mm) Long throw aluminium CPC cone woofer
Cross-Over Type: Active - variable between 50 - 150Hz
Cabinet Dimensions: Width 370mm
Height 370mm
Depth 370mm
Weight: 15Kg

Here is the back of the amplifier

That's just as likely to be the amp running out of headroom as it is the driver. You can only get so much out of a sub that small. As for replacing the driver, you need to match the T/S specs of the driver to the cab. And if you don't know the specs of the stock driver, specifically xmax, you have no way of knowing if a replacement would be better, or even as good for that matter.

Hello, I have the answer.
It is a manufacturing defect quality MS driver itself.
I have a 309i and avant devido noise is that the cable that goes from behind the driver's membrane, is too long and rubs when the driver is moving.

I giving solve tape strips and the other wire tying a small inward curve of the driver spider.

I hope you will help.
Anyway the subwoofer and not use it, has been replaced by SVS in my system.

A hug.
