Gone to RS today at lunchbreak and met the helpful guy who kindly demo some smaller bookshelfs for me last Friday (bought the Q3010 in the end). Spoken with him about being aware of the BX2 on sale at £150 and debating with myself if I should get one, and explained I have read good things about the speakers but never listened to it in person, he kindly offered to demo for me.
After listening to the demo, I just knew I must have it! I asked about how much stock they still have (I haven't walk to have lunch so no car, so any purchase will have to be after work), and to my disappointment he said there's only 1 left and it was in Oak colour, with no black left. But I really don't want Oak colour, as the rest of my setups are mainly black...he then said there's opened box black one, but it was £135 which was barely any cheaper than the new ones at £150.
I returned to RS after work as asked more about the opened box, and it turns about I could get further 10% off the £135. I ask if I would be about to use the -£10 for spending over £100 after the 10% off, and he said typically they wouldn't allow discount offers in conjunction with each other, so the 10% off would work out better than the £10 off. I don't know if I was showing disappointment of won't be able to get £10 off after the 10% off, he gone back to the counter's PC and did some checking, and then he offer me the deal price £115, as a gesture basing on the fact they have 3 of the BX2 opened box and was able to give me this low price! At this price I was very excited, but of course with opened box, there's still the concern of the condition that they are in.
He went to the storage at the back and grabbed the "opened box BX2" that's still in the original package. He opened it up to check the condition with me together, and to both our surprise, the speakers appeared not even been removed from the warps! Everything looks like new...so why "opened box"? On further inspection...oh the manual and warranty card (if there was one) are missing

So I ask him how would the warranty/guarantee stand if the warranty card is missing? He told me since RS would be handling the warranty anyway, all I have to do is fill in the 6 years guarantee card with RS like I did for my 3010, and they will take care of it if anything goes wrong!

And so I proceeded to the counter and paid the £115, and the nice guy helped me to carry the box to my car outside
Anyway I have just taken them out of box:
Have now set it up and burning them in. I am well chuffed for picking up practically a new pair of BX2 with 6 years guarantee for just £115!
Gonna need to get some better speaker cables though.
