Question about Audio Players & Recorders
I have an RCA surround sound system - model no. RT2760. The receiver is RT2760 home theatre receiver., Receiver and speakers are 4 ohm. Equipment specs = amplifier section: RMS output power: dolby mode with 10% total harmonic distortion. All front, center and rear channels are 120 watts 1 KHz, 4 Ohm. The subwoofer channgel is 120 watts (100 Hz 4 Ohm) Total RMS output power, dolby digital mode: 720 W. I want to replace at least the center and subwoofer speakers). What are my options. Can I use 8 ohm speakers (or 6 or ?) with my 4 ohm receiver?
No , placing 8 ohm speakers on a 4 ohm system is not advisable must use 4, even though it will work for a while the extra resistance (ohms) in speaker will end up cooking the output transisiters in amp.
Voltage = Current x Resistance
You could use something like this to reduce out put to speaker.
or wire two speakers say for centre channel together instead, but you need to wire them in parrellel not series...ie centre positive to positive of one 4 ohm then that to other 4 ohm positive and same with negitive.
Parallel..........Two 8 ohm speakers wired in parallel will have a total impedance of 4 ohms

You can plug in higher ohm speakers , the higher the ohm the higher the resistance is, it is a danger when you plug lower ohm speakers into a higer ohm Amp , at a high volume that will cause them to blow , the center speaker would be fine to use a higer ohm speaker , your best choice is to buy a Active Subwoofer, which means the sub has it's own power supply , and u can blast the thing as much as u like , thn u can turn the bass down on all the other speaker's so u can play it louder , and have the sub turned up has high as u like , this is the best way to get great sound with high volume , buy a Active sub woofer , any active subwoofer is ok , a active sub woofer has its own volume and inputs on the speaker ,
