Hey everyone. I have Rti150 towers and a csi5 center. Im powering them with an Emotiva Xpa5...here are the specs• Number of channels: 5
200 watts/RMS Channel into 8 ohms, all channels driven
• 5 channels - 8 ohm= 200 watts per channel
• 4 channels - 8 ohm = 230 watts per channel
• 3 channels - 8 ohm = 250 watts per channel
• 2 channels - 8 ohm = 275 watts per channel
• 1 channel - 8 ohm = 300 watts per channel
4 ohm rating:
• 5 channels - 4 ohm = 350 watts per channel
• 4 channels - 4 ohm = 375 watts per channel
• 3 channels - 4 ohm = 400 watts per channel
• 2 channels - 4 ohm = 450 watts per channel
• 1 channel - 4 ohms = 500 watts per channel
• THD+N at rated power output: 0.007%
• S/N ratio: >100db
So correct me if Im thinking wrong. Lets say these are 8 ohms, I know they are lower than that even though the specs say they are. In 2 channel mode Im getting 275 watts per channel. So if I use 2 extra channels It should be 460 watts going to each rti150 according to the 8 ohm ratings.I get this by looking at the specs running 4 channels at 8 ohms is 230 a channel. I guess another question is. when doing it this way, I remove the metal bridge connecting the binding posts. Will this change the ohms? I ask because if I measure the ohms with an ohm meter on each set of binding posts I get alot different reading from the tweets than the woofer side.
Anyways will this actually get more watts going to the speakers using 2 channels to each speaker?
• Frequency response: 10 to 120Khz (-3db) and 20 to 20 (with less than .15db deviation)
• Gain structure: 32db
• Transformer size: 1600VA Toroid
• Secondary capacitance: 60,000uF
• Weight: Approximately 70 pounds
