I have a pair of AR-6 speakers up for sale - and an upfront warning I have managed to dink one of the speakers but this has no influence on how they sound.
I bought these from this ad on PFM -*https://pinkfishmedia.net/forum/thre.../#post-5230537
I'm asking £450 plus postage - and a quick search seems to suggest that it would cost around £50 to deliver which includes insurance - UK only. They are separately boxed and each box weighs 10Kg each.
Some pictures:
And the 'dinked' speaker
And the base of that speaker
The speaker stands and gnome are not included in the sale
