Onkyo TX-SR600 with Polk LSi15 speakers?

[mattm]

<font color='#000000'>I have an Onkyo TX-SR600 receiver, and I would like to purchase PolkAudio Lsi15 towers. They rated at 4 ohms and have an efficiency of 88 dB. Does anyone have any experience with using 4 ohm speakers with the Onkyo? It says in the manual not to use speakers rated under 6 ohms, but I thought with good ventilation it shouldn't have any problems. Any thoughts?

Thanks..</font>

<font color='#000000'>Ventilation has nothing to with a receiver being able to power a set of 4 ohm speakers. 4 ohms means that the speaker just has less resistance on the flow of current, which causes the receiver to work harder since the speakers are power hungry.</font>
