It depends on you, really. Your listening style and what you expect/demand from a driver. If you don't need everything to get screaming loud and you want to cross them over at a low frequency, I would say yes. It will sound full and enjoyable.Would the Alpine MRV-F300 be okay to use with the Daytons? Looks like they are basically the same cutout size and depth as the Flutes.
In free-air (most door speaker scenarios), many drivers can be fully stroked with as little as 25-30w, so from that perspective the Alpine should be a good start. BUT, you won't have the control and headroom like you would from a proper 60-100w and it may be a bit soft and mushy sounding right when things start to get fun. The Dayton is a driver that can be stroked to full excursion in free-air with maybe 40w and sound fantastic, but it will also readily gobble up huge amounts of power and provide you with a very tight attack and incredible dynamics in an esoteric install. The stuff you can feel on your chest. Install dependent, of course.
It was a driver that I initially dismissed as being pretty and being yet another Dayton, but I played with a set and I was blown away. Most Dayton drivers are really very good so I'm not sure why I took that stance. They are incredible, full copper sleeve with a 3" edgewound coil and a very stiff cone. Very well composed driver even when you're piss-pounding them with lots of power. But they're not stiff suspension drivers, they're very musical. The control comes from the motor. We're talking top tier Morel level performance for a fraction of the price. That's something you can grow into over time by grabbing them now and upgrading your power later. And, they're beautiful!
