Not officially but there is a high frequency jumper bar on the back and you could remove that and patch into the tweeter feed.
Wouldn't advise doing so. They are an almost flat 3.3 Ohm load using a very simple crossover. Better off with one high current and powerful amp IMO.
Thanks, I have a fairly pokey 4 channel amp. I'm thinking about a pair of LRS's and while 2 of the channels could comfortably drive them... it seems a shame to leave the other 2 redundant if they could be used.
