Singing Karaoke Outdoor

Every year when we celebrate our son's birthday, we have friends over for a party. Kids play; parents/adults eat, chat and sing karaoke. We have been doing it since J's first birthday. We always have fun as usual. Adults have so much fun as the kids have especially when we sing karaoke. The only thing I don't like about it is that it's in July when the temperature in Texas is extremely hot! And so, we ended doing the party indoor. I just wish it will cool down a little bit so we can have the party outside. I would like to have an  outdoor loudspeakers so we will enjoy our singing, lol. We, Filipinos love to sing, though sometimes most of us don't even have talent in singing; we just want to sing and enjoy the company of our family and friends. I really think that having loudspeakers outdoor makes the singing more enjoyable; what do you think? I remember growing up, my brother had a big speakers that he used outdoor when we have parties at home. We enjoyed it being part of the special occasions.
