You are so lucky living nearby. Give them a reasonably gentle break-in 20 or 30 hours, they don't sound very good for the first few hours. After 100 hours they are nearly there. Keep cone excursion below 3 to 4mm each way (i.e. 6 to 8mm total). There is also a paper cone version which I have heard in same boxes and they sound good too, hard to pick the difference, except the paper cone ones I heard were barely broken in. I don't think you will be disappointed.
