Hey Everyone

It's been a while. I need advice on new outdoor speakers. I currently have 2 Bose Freestanding speakers by the patio around the pool. However, I need two more on the other side of the pool. I am looking for quality rock speakers, as I need something on the ground to match my 2 existing speakers. The speakers are being driven by a Denon AVR-2802 (my Outlaw stuff is inside). I have found SEVERAL types of rock speakers on the internet, but I can't hear them. What specs can help tell me the quality of the speaker (freq response)? And does anyone have first hand knowledge of certain speakers? Any input would be greatly appreciated.
