Question about Audio & Video Receivers
To protect the system, check the Ohm (ω) rating for the original speakers, which are most likely 8 Ohms (or perhaps 4). This is a measure of their resistance. You should only replace them with speakers of the same resistance (or higher). If you match them, you'll be OK, but if not, there is a vast amount of information on this topic available on the internet.
Note also, that it would be useful, but not critical to match the speaker sensitivity, which is measured on a dB scale - unfortunately, this specification is not always available. If the sensitivity is much lower on the replacement speakers, they will play quieter than you were used to with the original setup. If you have to crank up the volume to more than 80% of max on your system, than you may start to get distortion and will strain the system.
