David has a home theater system and the speakers are already built into the house, but he needs surround speakers. Leo says he can do that and then just wire them into his home theater system. It'll be the rear surround in a 7.1 Dolby system. Or, if he doesn't want to do that, he should just go with Dolby 5.1. He'll be just fine with that. He'll need to re calibrate, too. Of course, he could go all in and do Dolby Atmos at home, too.
Jose has built a man cave in his garage and would like to get better speakers for gaming. Leo says that he'll really want nice surround sound speakers. He doesn't need Dolby 7.1, as 5.1 will work just fine. Leo suggests avoiding Bose. It's not the best sound and not the best bang for the buck.
Scott WIlkinson recommends the Pioneer 22BS or the 52BS. It's designed by Andrew Jones and they're excellent. Onkyo and Denon make great A/V receivers as well.
