Thanks for the replies
I got my sums wrong on the replacement price from Meridian, It was £360.00 each I was quoted a few months back not £450.00 but still an expensive option for older speakers.
After reading several posts I see that the Seas H1212s as an alternative has mixed opinions on the forum.
Has anybody bought these recently, if I was to buy these are they old stock or are they still a current product?.
Does anybody know of a reputable source for these?
