Not really, but there are some things to consider.
Not so much brand limitations, but I/O considerations on your stuff and the sub.
The main one is to be sure you can integrate it into your system. For instance, if you don't have a LFE output, a sub swith only one line level input won't be able to plug into your system.
Check your stuff first. Is there a provision for preamp outputs and main inputs? If so, you can use any sub with a r/l line level input (and possibly outputs, but this is not mandatory.) All you would need is a pair of "Y" connectors (or another interconnect).
If you don't have these, you will need to limit your chouces to only those subs with speaker level inputs (and possibly outputs).
