Short answer. For a home gym, a rugged portable speaker such as the JBL Charge 6 (IP68, up to 24 hours) carries the round bell and music over bag work. For a club, use a larger speaker on mains power, mounted high, or two speakers at opposite ends of the room.
What a gym speaker has to do
Bag work is loud, and a phone speaker disappears under it. A gym speaker needs enough output to carry the bell and the music across the room, a rugged case that survives being knocked off a bench, and an IP rating for sweat, dust and the odd spilled bottle. For a club, the clearest round signal still comes from a dedicated gym timer with a buzzer; the speaker carries the music and voice cues.
Home gym or club?
- Garage or spare room, one to three people: a portable speaker around 1–1.5 kg with 20+ hours of battery.
- Small club, a full class on bags: a larger party-style speaker or a powered PA speaker on mains power, placed high so the sound carries over the bags.
- Two speakers at opposite ends of a room spread sound more evenly than one turned up to the maximum.
Ratings and toughness
IP ratings follow IEC 60529: the first digit is dust, the second water. IP67 means dust-tight and protected against temporary immersion. Drop resistance is not part of IP; it is the maker's own claim, so read what height and surface they tested.

2. Party or PA speaker on mains power
For a room full of bags, step up to a larger speaker that runs from the wall. Look for a handle, a stable base and a pole mount if you want it above head height.
- Mains power, so no battery to forget
- Mount it high, away from swinging bags
3. Wall or shelf mount
A speaker on the floor gets kicked and soaks up sweat. A wall bracket or shelf keeps it out of the way.
- Check the bracket's weight rating
Round cues
Any of these will play a round-timer app's bell loud enough for the room. FightNome, for example, calls the rounds and the strikes by voice, so a whole class can follow the same calls through one speaker.
FAQ
How loud should a gym speaker be?
Loud enough to hear the bell over bag work, not as loud as possible. Two speakers at opposite ends of the room carry better than one at full volume.
Is IP67 enough for a gym speaker?
Yes. IP67 means dust-tight and protected against temporary immersion under IEC 60529, far more than sweat requires.
