Short answer: choose the QSC K8.2 when the smallest, lightest cabinet and broader coverage are the priority; choose the QSC K10.2 for the better all-round main PA. They share QSC’s 2,025W peak amplifier platform, 1.4-inch titanium compression driver, DSP, flexible analogue I/O, pole mount and rigging options. The decision is principally about coverage, physical size, and the extra low-frequency and output headroom from the 10-inch woofer.
The K8.2 is the more portable and wider-dispersing speaker. At 12.2kg it is 2.3kg lighter than the K10.2, and its published 105-degree conical coverage is useful when one compact speaker has to cover a broad nearby audience. Its 8-inch woofer has a 58Hz measured bass extension and a 128dB published peak-SPL claim, so it is the sensible option for speech, fills, compact monitoring, and subwoofer-supported music systems where carrying size matters.
The K10.2 buys a modest but meaningful step up in full-range capability. Its 10-inch woofer reaches 56Hz in the vendor measurement and its published peak-SPL claim rises to 130dB. Its 90-degree conical pattern puts more energy into a narrower audience area than the K8.2. The reported ideal-subwoofer preference score is also higher (7.34 versus 6.88), although both results come from vendor Spinorama data and should be treated as useful guidance rather than a laboratory tie-breaker.
Neither replaces a subwoofer for demanding dance music or large-event bass. The K10.2 is the more capable standalone box, but its extra 2Hz of measured extension is not a substitute for a dedicated sub.
Buy the QSC K8.2 for the 2.3kg weight saving, wider published coverage, and a compact speaker that will normally work with a subwoofer.
Buy the QSC K10.2 for more published output, slightly deeper extension, and the stronger choice when one cabinet needs to carry more of a small event by itself.

QSC K8.2: $749.99 Amazon B&H Photo Video Guitar Center eBay
Pros: This is the standout measured result in this ranking: low-quality vendor data still returns a 6.88 ideal-subwoofer preference score, continuing the K.2 series’ strong showing at every driver size. Extensive onboard DSP, a titanium compression driver and QSC’s long market track record make it an unusually safe general-purpose 8-inch pick.
Cons: The underlying Spinorama source is low quality, so its apparent measured lead deserves some caution. An 8-inch woofer means a subwoofer partner matters even more than with the larger K.2 models.

QSC K10.2: $799.99 Amazon B&H Photo Video Guitar Center eBay
Pros: This is the standout measured result in this ranking: medium-quality vendor data returns a 7.34 ideal-subwoofer preference score, even higher than the well-regarded K12.2’s own result. Extensive onboard DSP, a 1.4-inch titanium compression driver and QSC’s long market track record make it an unusually safe general-purpose 10-inch pick.
Cons: The underlying Spinorama source is low quality, so its apparent measured lead deserves some caution. Its 130dB peak claim is modest next to some 10-inch rivals, and a subwoofer still matters for full-range music at event levels.
