Quality speakers make songs sound like the original artists singing live. My main speakers are two active Alto TS415's, rated at 2500W each, and they are supported by a matching Alto TS318s 2000W 18" active bass bin. 7000W in total! They produce crystal clear sound that will cope with audiences of up to 500 people.
To enhance the mood I use enough disco lighting to project colourful patterns on the ceiling, walls and dance floor of a very large hall. My lighting packages consist of a suitable combination DMX controlled lighting including modern multiple moving heads, par cans and lasers.
I do not use smoke/haze unless requested and also require permission from the venue management.
The video below shows my current rig minus my bass bin, and the extra lighting required for large venues. Note the use of the wall mounted TVs to display the karaoke lyrics, and music videos. I was using a dozen in Coyote Ugly before the lock down.
A nice setup.
I use two Shure SM58 wireless handheld vocal microphones, these are tough, and good sounding, which has made them the professionals choice.
My rig also includes a flat screen TFT monitor, a 42" large screen TV, and projector with a 100" screen.
