Don't get me wrong either, the statement after my posting is just part of the signature 'cuz that's what all the cool guys do. Right guys? OK, here goes.
Speaker systems are more than just a collection of parts. They are the end product (hopefully) of extensive research involving matching drivers, testing those drivers, designing a crossover that produces the least amount of frequency peaks and dips and good impedences, then putting them in a properly sized, damped and possibly ported enclosure. In the better systems there is also care given to off-axis response vertically as well as horizontal. Without going through this process again there is no good way of "beefing up" a loudspeaker.

Buy this book:
"The Loudspeaker Design Cookbook" by Vance Dickason:

Obviously, Vance's book is highly thought of among those that have experience in audio and electronics. However, it may be a little much if you're brand new to the game. You may want to start off with "Designing, Building and Testing Your Own Loudspeaker" by David Weems. Then move on to the Cookbook.

Whatever you do, unless you've got a degree in the physics of sound and electronics, DO NOT buy the Dickason book to start with. It is VERY involved, and will make your brain run out your ears. The Weems book is considerably easier to understand. Then, after you get into it, consider the Dickason book.

FWIW, and I've learned this here, the best thing to do is to look at established "kits" (really just published box blueprints and electronic crossover diagrams) and see how they were done.

FWIW, the best beginner's book I've seen is Ray Alden's 'Advanced Speaker Systems'.
