Wiring Polk Atrium 8 SDI to 4 Channel amp

I currently have the Polk Atriums hooked up by dual input to a OSD Audio 2 channel amp. 2x50w @ 4 ohms. Sounds great but want more power to them. Can I wire each input to a channel on a Denon E400 theater receiver and just do matrix audio (It plays same signal in all speakers)? That would keep each channel at 8 ohms correct? Denon e400 is rated around 90 watts per channel. Thanks!

    You are running one of them? I would be careful driving them to hard, two tweeters and one small woofer can only do so much outdoors

    Yes basically it has 2 tweeters and a dual voice coil woofer. Single channel in it runs at 8 ohms and 1 tweeter and woofer. You add the other channel and it runs both tweeters and woofer at 4 ohms.

    No running both but in parallel. Each speaker has 2 sets of inputs so its like running 4 - 8 ohm speakers.

    Ok.

    The woofer while dvc is still limited mechanically by the spider and surround... You can only drive it so hard.

    Your best bet to increase volume would be hi pass it and introduce a subwoofer

    Tried a 12" sub in a little pool cabana/bar I have. Sub was too loud for people around the bar. Tried it outside the bar and obviously lost all its bump. Fully understand outside audio is so much harder than in a room.

    It sounds great but sometimes you want that little extra "Amp to 11" sound. Better option might be 2 more speakers, run them all in single input and the 4 channel amp. That way I'm not driving anything too hard.

    You need to consider pro sound for amp to 11 results

    Ok, I see that Polk labels the binding posts as inputs on that speaker.

    BTW, the increase in the SPL you would get by going from your current amp to the AVR is about 1dB.
