How to model this shape?

Hello everyone, I'm trying to model this radio for practice:

http://s11.postimg.org/t37wyo8fn/radi.jpg

I started drawing a spline from the top view, and then extruded up, the problem that I'm having is with the back of the radio (marked with red circle), How can I cut this curve? maybe a boole object? the problem with boole is that ruins the topology...

Thanks for reading, any tip is welcome

You could use subdivision modeling starting with a cube, but in this case what I think I'd do is start out with a planar object modeled to fit the contours of the top view (with edge loops), and then put it in a bend deformer to form the bottom/back/top of the radio. Then I'd convert it to geometry and use the bridge and other tools to fill in the front and sides and proceed with SDS modeling.

Seems you were headed in the right direction. Draw a spline profile from the top for the front side radiused tampering, then draw a profile from the saide to match the radius, angle the side profile from the top view to match spline tangents. Combine the two profiles into one, mirror the profile, then use the create outline tool to make an outline of your profile, loft together. Or just extrude the one profile like you were, just not sure if the extrude's going to behave accuratly that way.

Or you could... draw the profile prom the top, subdivide some points on the backside of the profile ( backside of radio ) and use a bend deformer to bend the backside profile, may need to scale/stretch some points as needed. Kind of a quasi nurbs/box modeling style.

thanks a lot mayajunky and adamT, I always try to avoid subd modeling, but this time I think is the best option as you said. I'm on a right direction now, I'll post an update later!

here's my attempt.
A spline and deformers to start and then an extrude and a loft...

Good luck...
