I have been out of the business end since 2014 - but I think the old warehouse still has some passive 18's that are new in the box. Drop me a PM if you want me to check - they can be shipped to Canada. The drivers are basically a "Lab 18," and were exclusive to us from 2010-2014.

I am pretty sure you could get four 18's already in built cabinets and have money left over for a good pro amp. That is, of course, unless they sold out. There is nothing in this for me, either.
