喇叭power問題?

Chings,
本人的AMP rated output 中置是90W(8 ohms),
請問買喇叭時應選75W RMS/300W 或 125W RMS/500W ?
Thanks!!

What speaker are you looking at? The power spec of speakers are usually written like this: 25-120W

The small # (25) is the suggested minimal wattage your amp should provide to drive this speaker adequately, while the big # (120) is the maximum wattage your speakers could take before damage can occur.

Don't need to worry about your amp exceeding the maximum though as long as don't use crazy high volume levels.

Just use an amp which has rated power that is larger than the minimum suggested wattage and you will be fine.

I want to buy Klipsh.According to the spec :
RC-52 II is 125W RMS /400 W (8ohms) &
RC-42 II is 75W RMS / 300 W (8ohms).
Which one is better ?

The numbers 75W/125W RMS are the average power the speakers can handle without damages. Again, this should not be a concern to buyers and is certainly not an indication of performance.

Klipsch are very sensitive speakers so they are easy to drive. You shouldn't have any problem with either. Demo both and buy the ones that sound better to you.
