This speaker not easy to drive as most Cantons, due the low sensitivity 93dB and two parallel woofers what made the impedance fall under the nominal 4 ohms in the bass, reaching 2 ohms according this graphic below, in my experience with Canton you will need a
mus-cu-lar 200W Class D or a Solid State with a
b.i.g power supply capable of working well in 2 ohms, what not easy to find or cheap.

From 1985 to 1992 I had a similar model with 88dB and also 4 ohms, it made my new pro-audio pre-amp blow a diode in just afew days.
