“I recently purchased Polk T15's and T50's and Im trying to match an integrated amp or reciever with them. I'm thinking of Denon's DRA-800H. I need to know if this unit will be able to run both simultaneously?”

As long as the reciever has speaker 1 or 2/ front or rear connections, u should be able to use these speakers. I recommend at least 100 watt amp/reciever. Use good wire too.
Sorry, there was a problem. Please try again later.Yes this preamp amp unit has about 100watts RMS in an 8 ohm load. Always look to 8 ohm loads for specs. The peak rms 8 ohm load those Polk T15’s can take is 100, and they are rated for 50 watts RMS (8 ohm load). So these are matched well. The Dbi is low on the polks which means it takes more power to make them sound alive. But you have plent of headroom in the amp. They key for best sound, meaning this will make any rock sound good but strings, cellos and flutes are much harder to make high quality enough to sound real. I would recommend (after playing pro in military bands for decades and using super large sound system) never driving your amp beyond 50%. If it’s rated for 100watts rms then for best sound it should peak with the kick of bass at about 80 watts. You need a lot of unused power in the amplifier capacitors to allow hi Fi treatment of things that are quiet like the ting of a triangle or the soft breathy edge of a flute. Your speakers will also sound best ONLY at about 50-60 watts max. They say they take peaks of 100 but that means they would have already trespassed into sounding strained. Power review. Many companies openly lie. Power works like this. A 100 watt amp rated RMS in an 8 ohm load is the standard. You could take this same amp, remove the average rating of RMS then claim it is a 150 watt amp because it has super short peaks of power at 150 watts. You would then lie further and say it’s a 1,000 watt amp, because in a 1 ohm load it would have about 1000 watts. This does not mean there is more power present. It’s the same principle as electricity. If you take your household current, at 115 volts of pressure ( like the ohms resistance in speakers ) and say 10 amps of flow, there is a specific total energy present. The total power is called volt amps, or literally 115X10 = 1,150 volt amps of power. You could also reuse the voltage to 1,000 volts but now your amps of flow would be tiny, or 1.1 amps. The total power present is still 1,150. This is how speaker and amplifier companies maliciously lie to customers about their power in “watts” by not specifying the ohm load that goes with their watts. The ohm load is the voltage, or the pressure, and the watts is the amps or how fast it is flowing. So always pay attention to terms with speakers and amps of 8 ohm, RMS or average load ( not peaks which is irrelevant) and the sensitivity of the speaker in Dbi. Dbi speakers The rule of thumb is this. If you want a perceived increase in sound or a doubling of sound, you have to increase the db by 3. So if you are playing your speaker at roughly max, and you want it louder, you have to double your power from the amp from 100 watts rms to 200 watts rms to hear an increase. Or..... you could keep the amp ad get speakers that have a higher sensitivity Dbi. So if your speakers were rated for 89dbi and you got some better speakers with 98dbi then the same amp, running at less than 50% power, would sound MUCH louder. The polks have a really low sensitivity of 89.
Sorry, there was a problem. Please try again later.The simple answer is yes it will run both sets of speakers. But they would only be stereo left and right. The particular Dennon model is NOT a surround sound receiver. Therefore the exact same left and right audio, would be sent to both pairs of speakers. If you want to use the Polk speakers for surround sound, you need a 5.1 or higher surround sound receiver. If you are not needing the surround sound aspect, the smaller speakers would be best suited for use as an alternate room. But you're not going to get the fullness that you get from the T50's. And you shouldn't run them at as high of a volume as you would the T50's, then you would lose audio quality.
