I did a lot of reading and trying to find a reasonable $ for speakers to update a bit of sound in my rollergames. Well it was a lot easier than I thought. I didn't see any new threads except to buy complete kits. I'd say my speaker update is as good or better than the speakers in those kits. Best part is I spend about $75CAD. Crossover L-pad and 3 speakers. My only downside is the box speaker should have been different with more bass. But all in all sounds great now. And I ran the L-pad to the front of the box near the volume control for easy access.
