Best way to choose a new woofer?

[Dave W.]

I just picked up a set of Realistic Pro LX-7's; these have the linaeum tweeter much like the smaller LX-5's most people play with but with a slightly different box design (the tweeter is enclosed) and a larger woofer. I'm currently working on plans to update the woofer with something a bit nicer and was curious about the best way to pick a new woofer?

I can't believe it's going to be as simple as getting the 7" version of the woofers' that have been reccomended for the LX-5's, but I'm not quite sure where to begin since it seems there's much less info on the LX-7's than the LX-5's

Any ideas you all have would be greatly appreciated!

Thanks Much.
