What they actually do
Passive and active speakers for stereo and home theater, sold individually rather than in packages, so a system is built rather than bought.
The specification style
Power quoted as a pair — a sustained figure and a music figure — and frequency response given with a tolerance. Both are more conservative than the marketplace norm, which makes them comparable to each other and awkward to compare to a peak figure.
What the two Canton listings publish
The GLE 455.2 center speaker is specified more completely than any other center on this site: 80 W nominal and 140 W music power, a frequency range of 30 Hz to 30,000 Hz, crossover points at 400 Hz and 3,000 Hz — which makes it a three-way design — and a 6.3 in (160 mm) aluminum woofer. The ASF 75 SC subwoofer gives its power the same way, 60 W sustained and 120 W, but not its frequency extension, which is the one figure a subwoofer is bought on.
Buying Canton in the United States
We hold European Amazon references only, and Amazon.com had no offer for either on October 25, 2026. On the center speakers shelf, the Klipsch R-52C was $147 and the Polk Audio Monitor XT35 $260 that day; the only subwoofer on this site with a US offer was the Klipsch R-12SW at $259.
