Denon UD-M 31 mini HiFi system (Power Output ->22 W + 22 W (6 ohms); Power Supply -> 230 V 50 Hz). Panasonic SB-59 speakers (50 W rms, 70 W spike, (4 ohms)). Id like to upgrade my crappie micro room system. Been looking around some stores and found this really nice sounding Denon UD-M 31 mini HiFi system. Since its price is my entire budget, the money for the speakers wont come around for a while: 3, 5 years. The thing is Ive got these old stereo Panasonic speakers. Regarding that it is to be used in a small room at a fairly low volume, will this speakers stress out the amplifier because of its low impedance? If so, , can I somehow reduce this stress? Maybe increasing the impedance using small cables?
