Which FBT PA Speaker Fits Your Room?

Which FBT PA speaker fits your room?

Start with the room, not the wattage. Three questions decide almost every PA purchase:

  1. How many people, and how big is the room? A living-room-sized space and a 200-seat hall are different jobs.
  2. What are you amplifying? Spoken word and acoustic guitar need far less low end than a DJ set or a full band.
  3. Who is carrying it? If one person loads in alone, weight and handles matter as much as sound.

FBT gives you two ladders to climb. The XPRO and XLITE tops have a built-in 3-channel mixer and Bluetooth 5.0, so a mic and a phone can be the whole rig. The Ventis line is the step up: birch plywood cabinets and a DSP with 6 presets and a display, built for venues and working systems. If you can answer the three questions above, the speaker almost picks itself. Tell us your room — message us and we'll spec it — or use the table below.

The quick pick

If your room is… Start with Why
Small room to small venue, rehearsal, solo acoustic, speech, light DJ — up to ~100 people XPRO 110A (10") — $780 Punches above its 10-inch size — 127 dB peak, same max output as a 12-inch in Guide 1. Built-in mixer and Bluetooth, and the cabinet doubles as a floor monitor. A pair, or one over the X SUB 115SA, covers the top end of that range
Small venue, wine bar, DJ in a tight room, small church — ~50–100 people, with more low end for DJ and band sets XPRO 112A (12") — $779 More low end and output than the 110A, same mixer and Bluetooth, still easy for one person to carry
Mobile DJ or one-person load-in who still wants a 15" XLITE 115A (15") — $799 Lightweight molded cabinet, the widest coverage in this guide (90° × 60°), mixer and Bluetooth on board
Mid-size room, band, outdoor pop-up, larger church — ~100–200 people XPRO 115A (15") — $919 Biggest top in the XPRO line, most output, fills the space without a full rig
Bigger rooms, FOH or stage monitors, a system you will grow ProMaxx 114A (14") — $1,691 Widest-throwing pro top here — 135.5 dB peak, 90° × 60° coverage, DSP with your own preset slots
Pro venues and installs where tuning matters Ventis 110A / 112A / 115A — $1,691 / $1,901 / $1,953 Birch plywood cabinets, 900W RMS bi-amped, DSP with 6 presets and a display
DJ, dance floor, live band with real bass — any size where people should feel it Add a sub (see below) under any of the above Tops handle voices and mids; only a sub delivers the low end properly

Compare the speakers in this guide

All figures are from each product's own description on cs-proaudio.com. One honest note on power: the XPRO and XLITE amps are rated as maximum output (split LF/HF below), while the Ventis and ProMaxx amps are rated in RMS — they are measured differently, so compare them within each line, not across the label.

Speaker Woofer Power Max SPL (peak) Best for
XPRO 110A 10" 1,500W max (1,200W LF + 300W HF) 127 dB Small rooms to small venues, speech, acoustic, monitors — pair it or add a sub for the bigger end
XPRO 112A 12" 1,500W max (1,200W LF + 300W HF) 129 dB Small venues, DJ, small church
XLITE 115A 15" 1,500W max (1,200W LF + 300W HF) 130 dB Mobile DJ, wide rooms, one-person load-in
XPRO 115A 15" 1,500W max (1,200W LF + 300W HF) 130 dB Mid-size rooms, bands, outdoor
Ventis 110A 10" 900W RMS (700W LF + 200W HF) 131 dB Compact pro top, installs, monitors
Ventis 112A 12" 900W RMS (700W LF + 200W HF) 133 dB The pro all-rounder
Ventis 115A 15" 900W RMS (700W LF + 200W HF) 133 dB Biggest Ventis top, larger rooms
ProMaxx 114A 14" 900W RMS (700W LF + 200W HF) 135.5 dB FOH and monitors in larger spaces
X SUB 115SA sub 15" 1,200W Class D 135 dB Bass under XPRO / XLITE tops (down to 42 Hz)
SUBLINE 115SA sub 15" 700W RMS 135 dB Bass under Ventis tops, cardioid setups
SUBLINE 118SA sub 18" 1,200W RMS 137 dB Big-room low end (down to 33 Hz)
Q 118SA sub 18" 1,200W RMS 139 dB Top of the range — deepest (30 Hz), cardioid arrays

Same job, different tools: every top in this guide is a 2-way bi-amplified design. The XPRO/XLITE line trades on convenience — mixer, Bluetooth, 4 DSP presets, stand socket and monitor taper in one box. Ventis trades on control and cabinet: birch plywood, 6 DSP presets (Original/Live, Vocal, DJ, Touring, Loudness, Warm) with a display, and rotatable horns across the line. Pick the convenience or the control; the room size picks the woofer.

Which sub goes under it?

  • X SUB 115SA — $1,080. The sub FBT designed as the low-frequency companion for the X-PRO and X-LITE series: 15" woofer, 1,200W Class D, 4 DSP presets, down to 42 Hz. The natural partner for any XPRO or XLITE top.
  • SUBLINE 115SA — $1,850. The Ventis-class 15": 700W RMS, DSP with 8 presets including cardioid configuration, so a pair can keep bass off the stage and out front where it belongs.
  • SUBLINE 118SA — $2,691. The 18" step-up: 1,200W RMS, down to 33 Hz, DSP with 6 presets and a digital delay line for aligning flown or stacked systems.
  • Q 118SA — $3,060. The flagship sub: 18" woofer with a 4" voice coil, 1,200W RMS, 139 dB peak, response down to 30 Hz, and DSP presets (Original, Deep, Punch, Infra) plus dedicated cardioid-rear presets for two- and three-sub arrays. Baltic birch cabinet.

One speaker or a pair?

  • One speaker works for speech, a solo act, or a monitor. Buy the second one later — the lines are designed to grow.
  • A pair is the right call for a DJ, a band, or any room where people sit on both sides. A matched pair also saves you a stand-and-cable hunt later — see the ready-built systems below.

Don't forget the rest of the rig

A speaker on the floor is half a system. Before you check out, make sure you have:

  • Stands — a pair of speaker stands gets the sound over heads instead of into knees. Every top in this guide has a standard stand socket.
  • A sub pole — mounts the top speaker above the sub, cleanly and safely. The subs in this guide take a standard M20 pole mount.
  • Cables — XLR cables from your mixer to the speakers, plus spares. One failed cable ends a gig.
