PMC Passive Studio Monitors For My HiFi?

Hey everyone.I found a Pro Studio Equipment Dealer with the TB2S+ at a pretty good price.I emailed them and PMC wondering how the would fair in my listening room as hifi speakers but haven't heard back.The TB series is gone from the consumer side and this appears to be the evolution of the TB2 with the latest Sonelex tweeter,doped woofer and Studio Black Nextel finish....90db.8ohms nominal never dropping below 5.6 ohms I would think they would sound great with 15watts of EL84 power at sane listening levels..What do you guys think?
15 watts at 90db will run out of steam easily.  You won't get much bass.  I run 10.5 watts into 94db speakers and can't push it.
