What they actually do
Passive loudspeakers and network audio electronics, sold separately.
The specification to read
Frequency response with a stated tolerance. “45 Hz–22 kHz ±3 dB” is a specification; a range with no tolerance is a claim.
Two products, two specification styles
The Monitor S10 B bookshelf pair is one of the most completely specified speakers on this site: two-way with a 3,400 Hz crossover, 60 W RMS and 120 W peak stated as both, a 20 to 120 W recommended amplifier, 4 to 8 ohms, 88 dB sensitivity, 42 Hz to 32 kHz, a 4.3 in (110 mm) coated paper woofer and a 0.5 in (13 mm) Mylar dome tweeter. The one figure it gives without its qualifier is the frequency range, which has no tolerance.
The MMS 730 network player is specified the other way round: it names its converter — a Wolfson DAC — which is rare, and leaves out the maximum sample rate.
Buying Magnat in the United States
We hold European Amazon references for both, and Amazon.com had no offer for either on October 25, 2026. On the bookshelf speakers shelf, the Polk Audio pair at $149 and the Edifier at $110 had US offers that day; among network players, the WiiM was $99.
