Townshend Seismic Isolation speaker bars. 
Set of 4, size 1, specified by Townshend audio for the ATC SCM40 passive speakers, which means, due to the mass of the particulary heavy drivers at the front of the cabinet, the usual matched spring tension speaker bar pods from them don't really work very securely. 

So, with discussion with Sue and their technical chap they came up with the combination of Yellow pods for the rear bars, and green or blue pods for the front, whichever was best suited, a combination that means the speakers sits perfectly on the bars without being precarious, and have the perfect amount of wobble and bounce.

The offered sale is 4 blues on two  bars and  4  yellows on the other two bars, suited for the ATC speakers, but, keep reading....

Excellent condition, original box, check my feedback, I sold my ATC SCM40 a year or so ago, and just haven't got around to selling these.

I have 8 Green pods to swap for the yellow and blues if required, Thereby meaning they would be usable with many speaker types.

1 of the 8 green pods has a tear in the rubber surround, doesn't affect its performance of course. See photo of the wounded one. 

Please note, to be clear, you will receive 8 pods and 4 bars. 

Collection welcome from either Lee on the Solent or Gosport.
