Speakers

The karaoke mini hi-fi on the living-room shelf:

is still the family stereo in a lot of Guatemalan homes. It runs off the mains, comes as two tall speaker boxes or a single tower, and is built for a get-together on the patio, with microphone inputs, a karaoke mode that strips the vocals out of a song, USB, FM radio and Bluetooth. LG’s XBOOM range and Sony’s party systems are the names most people know. Sound for a church hall or a rented event is another purchase, and the powered PA speakers that sit on stands are under audio.

Portable speakers for Monterrico sand and Río Dulce spray:

the IP code on the box tells you more than the wattage. In IP67 the first digit covers dust and the second water: a 6 is sealed against fine sand, a 7 survives a dunk. An X in place of the first digit, as in IPX7, means it was tested against water only, fine beside a pool and a gamble on the black sand of the Pacific coast. To play two speakers together, check the generation as well as the brand. JBL’s Flip 7 and Charge 6 link through Auracast and will not pair with the PartyBoost models before them, such as the Flip 6 and Charge 5, so a used speaker bought to match yours may refuse to talk to it. A Charge-size JBL costs around Q1,500 new, and a karaoke mini hi-fi from about Q1,800 to Q3,000. Both lines are refreshed often and outgoing models are marked down hard when the new ones land, so the clearance price of a new one is the ceiling for a used one. Below that, a portable loses value with every hour of battery it no longer holds.

Bookshelf pairs and the amplifier they depend on:

a passive pair has no power of its own and stays silent until it is wired to an amplifier, which is why the speakers from an old stereo so often turn up alone. Active bookshelf speakers from Edifier or Klipsch carry the amplifier inside one box and plug straight into a turntable, a computer or a TV. Under a television a soundbar is tidier, and those sit with TV and film; earbuds and over-ears are in headphones.

Battery hours, cone edges and a JBL the app cannot find:

on a portable, the battery is most of what you pay for, and it is sealed inside the case on most models, so a speaker that now lasts a couple of hours will stay that way. Ask for it fully charged and let it play off the cable while you talk. A case bulging at the seams can mean a swelling battery; leave that one. Salt water left in the charging port after a beach day shows up as green crust on the contacts. JBL is copied heavily, and the quickest test is software rather than looks: a genuine Flip or Charge appears by its model name in the JBL Portable app and can update its firmware there, while most copies pair under a generic name the app never finds. On bookshelf and old stereo speakers, take the grille off and look at the ring around each woofer. Foam surrounds crumble with age and a split edge buzzes; it can be re-foamed, but count it as a repair. On a mini hi-fi, try every source, both mic inputs and the CD tray included.

Resetting, photographing and handing over a speaker:

someone coming in from Escuintla or Jalapa wants proof it works before the trip. Give the exact model and generation, the hours the battery lasts now rather than the figure on the box, and photos of the charging port, the cone edges with the grille off and any scuffs. List what goes with it, down to the remote and karaoke mic. Reset a Bluetooth speaker so it stops reaching for your phone, sign an Echo or a Nest out of its account, and if it is a passive pair, say so in the title. Then meet somewhere with a socket, so a mini hi-fi can be heard on the mains and a portable on battery once the cable is pulled.
