Can I replace my 4ohm cinema sound speakers with 8 ohm ones?
Answers:
your best sticking with 4ohms
You should check your amp to see if it can handle the added resistance.
Yeah why not? Wire yourself for sound!
You could but you would have reduced output from your amplifier ie. lower sound levels.
Power in simple terms is current squared times resistance. Fix the current and double the resistance, get half the power. Quieter.
Yes you can most amps will handle 8 ohm speakers but you might notice they are not as loud as the 4ohm
There is no problem going to higher impedance as far as the amp is concerned (assuming it's a modern transistor-ouput amp). The MAXIMUM power output capability of the amp will be reduced by about 50%, but you seldom use the maximum power capability of an amp unless a) it is really underpowered or b) you play matierial with very low frequency sounds at high volume. The reduction in volume at normal levels is only 3db, just noticeable to the human ear and easily compensated by turning up the volume control a little.
