I've had a couple of pairs of SBL's over the years. The first pair were new so no real issues but I bought a pair a couple of years ago and to be honest I was disappointed. Unless they have been well looked after the gaskets between the woofer and tweeter boxes will need replacing, not too difficult but at around £140 for two foam gaskets, some tiny aluminium plates and a tube of silicone sealant, not cheap. The tweeters are also pretty weak, they can sound rather tinny and scratchy but new ones can be sourced from Scanspeak. They are quite fussy about placement, as close to a rear wall as possible. They need a fair amount of driving but your Albarrys should work well. This all sounds a bit negative but if you have the patience to sort them out they can sound very nice. I hope this helps
