Go for it-

In general to achieve the most isolation the same principles as studio isolation apply. Are you trying to isolate from the room you are in, next to it? Or from the rest of the house?

A few thoughts- lead/rubber sheets and MLV are widely regarded as overpriced and having no real isolation benefit compared to cheaper mass (drywall, MDF, OSB etc). Also one of biggest things for isolation is decoupling- depending on if this is going to be a single or double leaf design, the way you figure out how to decouple the inner leaf to the outer leaf, and then the whole box to the floor will likely be the biggest factor that determines how much isolation you get.

Also like a studio, the best 1st step is to determine how loud your source is, and how much isolation you need.

One thing to consider is that if this thing is really small and sealed up really well, it is going to get hot in there. A speaker driver has about 5% thermal efficiency- the rest going to heat. 45w is ~150btu...
