I didn't find constrained layers with bracing to work any better than bracing alone. Raising the panel resonant frequency is a side effect of bracing, but in and of itself doesn't reduce panel vibrations. No matter what the panel resonance frequency if the internal pressure isn't enough to cause the panel to vibrate it doesn't matter. Adequate bracing alone accomplishes that. So does mass, and mass doesn't raise the panel frequency, it lowers it. Knowing how these different methods compare requires building cabs of the same dimensions of each configuration and then measuring the results. That's not something the average builder is going to do, but since I make my living designing speakers it's something I had to do to be sure of which delivers the best result.
