Gym / fitness floor — high-energy music, 30 x 18 m
Problem. A large fitness floor needs energetic, even music across the whole training area, with enough headroom to carry over treadmills, plate noise and a crowd, while staying intelligible for a live instructor mic. Ceiling height and a hard, reflective room make coverage uniformity the real challenge, not raw loudness at one point.
Answer. This preset configures the planner for a 30 x 18 m floor at a live-event SPL target, a ~12 m listener distance and 60% power, using a wide-dispersion point-source cabinet (here a KGEAR GH8) as the coverage unit. The planner reports SPL at the listener and the per-cabinet coverage radius, then divides floor area by that radius to suggest a baseline cabinet count for even fill.
02 / In depth
How this preset reads — the engineering view.
Gym audio is an even-coverage problem before a peak-SPL problem. Members spread across the whole floor, so the design goal is consistent energy from any station rather than a single loud sweet spot. A wide-dispersion point source distributes music across a broad footprint, and stepping several cabinets across the ceiling plane keeps the level uniform as people move between zones.
The preset assumes a 30 x 18 m floor, a live-event SPL target, a listener distance of about 12 m from the nearest cabinet and a 60% power setting to leave headroom for peaks. The cabinet shown is a KGEAR GH8, a wide-coverage point source TechnoGuru works with where the application fits; it is one valid choice among several. Switch to any other point source in the dropdown to compare the SPL and quantity implications for the same room.
Read three outputs: SPL at the listener against the target, the -6 dB coverage radius (use it to step cabinet spacing along the ceiling so zones overlap rather than leave dead patches), and the suggested quantity from area-divided-by-coverage. Adding cabinets or raising power moves the level up predictably; the planner is a triage pass to bracket the count, not the final loudspeaker layout.
What this preset deliberately does not model: the reverberant field of a hard-floor, mirror-walled gym (which inflates effective level and can blur intelligibility), the separate instructor-mic and studio-zone systems most gyms run on their own amplifier channels, subwoofer pairing for low-end impact, and the DSP tuning that actually delivers even coverage on site. Final make, model and quantity are selected after drawings and site conditions are reviewed and remain subject to project requirement, consultant or client approval and availability.
To take a gym audio brief forward, use the brief wizard or /contact to hand off a safe enquiry summary; TechnoGuru's pro-audio and systems-integration scope covers the amplifier, DSP and zoning design that sits downstream of this coverage estimate.
What this preset deliberately does not solve
- Reverberant field of a hard, mirrored gym is not modelled and will inflate effective level.
- Instructor mic, studio zones and subwoofer impact are separate amplifier-channel and system decisions.
- Cabinet count is a coverage-triage baseline; the final layout comes from drawings and a site review.
How this preset differs from its siblings
The sibling BGM presets (hotel lobby, rooftop lounge) target low, conversation-friendly levels with discreet point sources, and the auditorium presets prioritise speech dispersion at a fixed audience. This preset is the high-energy, whole-floor music case: a live-event SPL target, a wide-dispersion point source and a coverage-count answer for a large, open training area where uniform energy from any station is the brief. Use this preset when music has to fill an active floor evenly rather than sit politely in the background.

K-array Domino KF212: SPL & Coverage Preset
In a 25 x 18 m live event space, the practical question is not just how many Domino KF212 boxes to hang but whether the SPL reaching a listener at 12 m still lands in a usable range once drive is pulled back from full output. The 90 deg x 60 deg dispersion also has to be checked against the room's width before assuming a single hang covers the floor edge to edge.
