rca home speaker system 1000w image

Q. I have RCA RT2910 1000W Home Theater System. the amp/box will not fully sustain power, the red power/standby light fades/flashes in a non-repetitive pattern. there are no external fuses. ive checked under the power bored, no burns/damage. the previous owner ran non-stock extra speakers also. ive been told the problem may be a transformer, diode, or bridge. EMAIL:mbg757@gmail.com if need any other info.

Answer

I have a RCA Home Theatre System, RT-2280?

It puts out 80 watts per channel at 8ohms and I am wondering what is the most powerfull speaker I could add to the system. For example could I connect a pair of Floor Speakers with a max of 100 watts or should I connect something that is lower than 80watts?

Answer
speakers are rated to a max input power so say a 300W speaker would be OK even 1000W would be OK, but not a 50W.

Next I think a new receiver is a good idea, but if you want new speakers check the sensitivity rating 20Hz to 20kHz look for a speaker that has a higher rating, i.e a speaker rated at 86 db sensitivity will sound halve as loud as a 89 db speaker ( 3 db meaning twice the spl) . the best mid priced speaker I have found for this issue is Klipsch with 91db- 103db.

But these can sound a little bright unless paired with a Denon receiver or Adcom separates. You should upgrade both to get the most out of the speakers but better speakers are the best to get first.
