If your receiver also lacks L and R stereo pre-outs, some subs will accept L and R speaker level
inputs. (You don't need to use heavy gauge speaker wire for that - the sub won't draw significant power from those cables.)
Those subs will also have a variable low pass filter, to limit the frequency range played by the sub. That's not as good as a crossover, because it doesn't prevent low frequencies from being sent to the main speakers, but it's serviceable.
If you got a sub that had the L&R line level inputs but no speaker level inputs, there are adapters, mainly sold for car audio, that take speaker level signals to line level.
If the sub had a single RCA input, that'd be a problem, because you want to mix the L&R signals to mono.
I don't know whether any of the subs with a control labelled "crossover" really perform that function, or whether they only have low pass filters.
You aren't SOL. You may end up with a sub-optimal solution, but you'd be better off than you are know, unless your L&R speakers are strong in bass.
