For most Dallas-Fort Worth events, a pair of powered 12 inch or 15 inch speakers on stands covers up to about 150 guests in one room. From roughly 150 to 350 guests you want that same pair plus a subwoofer, or four speakers if the room is long. Above 350 guests, or outdoors, the job moves to a line array with subwoofers and a delay position for the far end of the room.
What decides how many speakers you need?
Guest count is the starting point, but the room does most of the work. A 200 person ballroom with a low ceiling and carpet needs less power than a 200 person barn with a metal roof and a concrete floor. Three things set the count: how far the back row sits from the speakers, whether anything blocks the line of sight, and how loud the room needs to get. Dinner and speeches need even coverage at a conversational level. A dance floor needs headroom, which is where the subwoofer comes in.
The rig scales in both directions. A church sanctuary this year ran on two DML500 flat panel speakers on stands with two subwoofers on the floor, panels chosen because they blend into a limestone wall. A convention center stage in Dallas carried a country band on the same panels over a BassBoss SSP118 subwoofer. Same idea, different count.
How many speakers for 100 guests?
Two speakers on stands, one on each side of the DJ or the head table. At 100 guests in a typical DFW ballroom the back row sits around 40 feet out, which a pair of 12 inch powered speakers covers with room to spare. Add one small subwoofer if there is dancing. If you are planning a wedding with a separate ceremony space, plan a second small speaker there rather than moving the reception rig mid event.
How many speakers for 200 guests?
Two 15 inch tops and one or two subwoofers for a square room. If the room is long and narrow, which describes a lot of DFW event barns and hotel ballrooms, four tops beat two bigger ones: two up front for the dance floor and two on delay down the room, so the far tables hear speeches at the same level as the front tables. Our BassBoss powered subwoofers carry the low end for a 200 guest reception, so the top speakers stay relaxed and toasts stay clear once the dancing starts.
How many speakers for 500 guests?
At 500 guests a line array speaker system earns the truck space. An array stacks several small elements per side and throws sound evenly from the front row to the back wall, so table 50 hears the same level as table one. Plan on two arrays plus four to six subwoofers indoors, and a delay position if the room runs longer than about 120 feet. Corporate general sessions at this size also want front fill for the first two rows, which sit below the array coverage.
Do I need a subwoofer?
For a wedding reception, a quinceanera or anything with dancing, yes. The tops handle voice and most of the music, and the subwoofer handles everything below about 100 Hz. Leave it out and you either lose the bottom of the music or push the tops past where they sound clean. For a conference with speeches, panels and video playback, a subwoofer is optional. It helps with program video and walk in music and costs little to add.
What does speaker rental cost in Dallas-Fort Worth?
Typical DFW market rates: a two speaker system with stands, a mixer and a wireless microphone runs about $300 to $500 delivered and set up. Adding a subwoofer puts most packages in the $450 to $700 range. A 500 guest line array package with subwoofers, delays and an operator typically runs $1,800 to $3,500 depending on the room and the length of the event. Delivery inside the Dallas-Fort Worth metro is usually included, and Rockwall, Waxahachie and points past Southlake sometimes carry a travel line. The longer version, with what a package includes, is in our guide to AV equipment rental cost in Dallas-Fort Worth.
What changes for an outdoor event?
Outdoors, sound that passes the last row keeps going, so plan on roughly twice the speaker count for the same guest number. A 150 guest outdoor ceremony in Frisco or McKinney wants four speakers rather than two, placed closer to the guests. Wind carries sound away from the seats, so we aim the outer speakers in toward the rows rather than straight down the aisle. Power matters too: a small ceremony rig wants its own 20 amp circuit, with the caterer's coffee urns on a different one.
An outdoor ceremony this year is a good picture of the small end. Lapel microphones on the officiant and the couple, a condenser microphone on the string quartet, and two EV ZLX speakers at the front rows, with our De-Feedback system on the microphones so the level could come up outdoors and every word carried to the back row. You can hear that ceremony on our weddings page.
At the other end of the outdoor scale, under a covered pavilion in Dallas-Fort Worth this year, open on every side with string lights overhead, a wedding reception ran on a pair of BassBoss DV12 speakers built for outdoor use, and the dance floor stayed full to the last song.
FAQ
Can I just use the venue's built in system?
Sometimes. Ceiling systems in DFW hotel ballrooms are built for background music and paging, and they are usually fine for a plated dinner with a couple of toasts. They rarely have the low end for dancing, and the house microphone is often a single wired podium mic. Ask the venue for the input list and which microphones are included before you decide.
How many speakers do I need for a 300 person conference?
Two tops per side plus a delay pair if the room is deeper than about 80 feet, and a subwoofer if you are playing video or walk in music. Add a monitor speaker on stage so presenters can hear themselves.
Do the speakers have to go on stands?
For anything with an audience seated at tables, yes. On the floor a speaker fires into the backs of the closest guests and stops there. Stands put the driver near ear height for a standing person, which is where the coverage starts.
How far in advance should I book?
For Saturday dates from March through June and September through December, six to eight weeks out. Weekday corporate dates are usually available with two weeks notice.
Can you set it up and leave?
Yes on sound equipment rentals for smaller events. For anything with speeches, a live band or more than about 200 guests, an operator on site is worth the line item.
