Hi, How did you manage to get in the luggage, have you checked it as a separate baggage. I am currently in UK thinking of getting SVS - SB1000.
As this is 13 inch cube, I think I can keep it in Checked baggage with few clothes as protection.
Please suggest.
If you still haven't traveled than may be my answer can help you

I will very strongly advise you to send your stuff through out of gauge belt and with my exp i never faced any issue .(heathrow --> delhi always)
Customs(Only Delhi)
Generally they wont care for suitcase and even if they ask just say old speakers & used with cost less than 50 thousand (They only know bose even lot of my friends

For boxes they might ask and will have a scan Thats it
With my exp i noticed BA airline most of the time allow oversize bag for free (please also confirm in email apart from site
