Unfortunately I couldn't find it to buy at all here in Sweden, new or used. We do have reselling, but since it's a small country, looking for something specific to buy can be hard. And if I were to find it new though, it would still be twice of what I paid for the ones I have now.
But the speakers I have use spring clips, shouldn't I be able to replace the speakers in that case? I'm not looking to buy these speakers long term anyways, still only 17 and don't have a job, so these doesn't have to hold for many years.
