JBL EON615 15-inch powered PA speaker
A model number beats a category. Write just speaker and the sizing falls back on averages; name the EON615 and the quote is built on that cabinet's real carton.
A powered 12–15 inch PA speaker packs to about 28 × 20 × 18 inches at 30–60 lb. Actual weight drives the price on the heavier powered models; the woofer cone and the amp module are the parts to protect. Since the final figure hinges on your lane, your deadline, and the carton you actually seal, quote real measurements, not a hunch.

Real ZIP to real ZIP, rated live. Swap either end of this lane and the price shifts more than any packing decision would shift it.
Run the divisor and you see who is being billed: 30 × 20 × 16 ÷ 139 gives about 69.1 lb, comfortably above the 49 lb this speaker weighs, so the rates below charge for the carton rather than the cabinet. Any carton you can shrink pays you back immediately.

These are checkout figures: the label cost and SMKlog's share are both inside, and nothing gets appended later. FedEx Smart Post came out ahead on this run at $83.50. Rate tables shift week to week and no two lanes match, so let this stand as one documented data point and pull today's number for your own pair of ZIPs.
Once boxed, expect about 28 × 20 × 18 in. Firm foam belongs over the woofer grille, a powered unit belongs in a double box so the amp plate stays put, and the pole-mount cup and handles want padding of their own.
For a 15-inch powered cabinet, 30–60 lb is normal. Billing follows the bigger of real and dimensional weight, so a carton with too much air in it costs money regardless of what the speaker weighs. Measure after sealing.
Lane, service tier, and carton. Dallas to Pittsburgh covers a lot of ground, and even so the four services above only spread from $83.50 to $90.71 on this box; a shorter lane compresses that further while air options stretch it. No single flat price would survive contact with a real route, which is why the calculator asks for yours.
A carton around 28 × 20 × 18 in is the usual target. Lay firm foam across the woofer grille so no load can reach the cone, double-box any powered unit to keep the internal amp plate from shifting, and give the pole-mount cup and handles their own padding so they don't crack.
A 15-inch powered speaker generally packs out at 30–60 lb. Remember that the billed figure is whichever is greater, the scale weight or the dimensional weight (length × width × height over the carrier divisor), so check both on the sealed carton first; an optimistic guess gets invoiced back to you after delivery.
Cover the grille with a slab of firm foam so handling loads never touch the cone, and box the cabinet tightly enough that it cannot tumble face-first. Caved-in cones account for more speaker shipping claims than anything else.
A powered cabinet carries its amplifier with it, so it weighs more and wants extra padding behind the amp plate. A passive cabinet is the easier ship, lighter and simpler, though the woofer grille still needs protecting.
Billed weight, lane length, and speed are the whole equation. A 28x20x18 in carton packs out near 45 lb, yet its dimensional weight runs 73 lb (L x W x H / 139); since the greater figure is what gets billed, quotes are built on 73 lb rather than 45. More zones or a faster service scale it upward from there. Run your real route and carton through the SMKlog calculator for live USPS, UPS, and FedEx pricing.
Ground on UPS or FedEx, as a rule. Boxes this big and heavy route better on those networks, and since USPS applies dimensional weight past one cubic foot as well, there is no small-parcel loophole here. Pick the tightest carton that still leaves two to three inches of foam around the cabinet; each saved inch chips away at the 73 lb billed weight. An online commercial-rate label typically undercuts the counter by 20-40%.
Ship them separately; it nearly always prices better. A combined box carries double the weight and lands in the surcharge band carriers reserve for large, heavy parcels, whereas two mid-size cartons each stay inside normal rate tiers. Separation also means the cabinets cannot knock into each other, and a delay to one box does not strand the other.
