Adding to the earlier comments about the ability of the Yamaha receiver to handle the load that will be presented by the speakers you are purchasing, I would point out that marked on the rear panel of the Yamaha, next to the speaker terminals, are the words "A or B: 8 ohm min/speaker." Also, it does not have a specified power rating for 4 ohm loads. So I would definitely not use that receiver with speakers having less than an 8 ohm impedance.
Also, the Yamaha's frequency response is only specified down to 40 Hz, which might lessen its effectiveness in breaking in your woofers.
Finally, I would assume that like most aspects of its design the protection mechanisms it incorporates are designed to a (low) price point. Which means that if it fails in certain ways it could conceivably damage your speakers.
