Don't know where you get $1200 from mate but I got mine direct from the maker in the UK for a heck of a lot less than that, even with the exchange rate at that time. Would you like his email address, I could PM it to you.
I left the crossover box fitted to mine and then just replaced the cans = cat gone with original cans. Not noisy. Original cans 16kgs, TOR's 12kgs, current cans 6kgs for the pair.
Just followed that link Richard, pfft $1200 glad I got mine from the maker.
