Let me explain. I'm interested in using an Arc as a centre speaker, but they tend to come in pairs. I might be able to buy a single new unit, but thought it more cost effective to buy an ex-dem or 2nd hand pair. With enough shopping around, I think £1500-£1600 for a pair would be achievable. But the 2nd speaker wouldn't be much use to me, so I'm wondering if another member would be interested in buying a pair jointly, for their own centre speaker, or final speaker in a 6.1 set up What do you think?
