The speaker im after is the midrange 3" dome unit and I think it is a SEAS H226. Is it the same for MS150 and 150.2?

Anyne who has a spare one would be greatly appreciated.

Do be aware that the midrange drivers are different on the MS150 and MS150.2. The MS150 driver has a clear dome and is part number 8480146 but the MS150.2 has a black, sticky dome and is part number 8480160.

Martin (user 'Dillen') often has them in stock on his Beoparts website and I can personally vouch for the quality of the parts he provides and his excellent service, as I had to buy a new driver from my own MS150.2s earlier this year. It looks like he has none in stock at the moment but it's worth keeping an eye out or sending him a message.

Yes, it sounds like you'll need two of the correct unit.

As an aside, my faulty midrange was making the same sort of noise and it turned out that the voice coil had literally fallen off the coil former. This is not something I've seen before in nearly 20 years of designing, building and repairing speakers!

Need Martin!!!!!!! 

I can hardly post anymore. I keep getting timeouts. Quite annoying.

Carefully  take the driver apart (watch out for the very delicate wires, a bit tricky because of the sticky stuff used to hold the pieces together) .
Glue back the voicecoil to its ridge on the inside of the plastic dome using a small amount of 2-comp epoxy glue.
I use Araldite Standard (the blue slow setting one).

Typical symptoms are rattling, distortion or a completely silent midrange.

Thanks Martin, 

Do you have any spares? Sent you an email last week.

Thanks

None at present, I'm afraid.
