There are various ways to skin this cat.
Just as in turntable plinths, one school advocates the addition of mass, in the form of thicker cabinet walls and additional internal bracing, to make the cabinet as rigid as possible. All cabinets resonate, always at more than one frequency, and the goal of this design is to quiet those resonances as much as possible. The addition of mass, usually lowers the frequency of the resonanance and lowers the "Q".
Another design school advocates making the cabinet lighter. The obvious effect is that the resonances, though louder, will be higher in frequency. If they can be moved up in frequency, they are both less bothersome to the ear, and they tend to be of higher "Q". "Q", or quality factor has to do both with how wide the resonance is and how quickly it clears, or stops ringing. Even if the high frequency resonance is louder, if the ear is less sensitive to resonance in this range and the resonance stops sooner, it will have a different sound than the other example, above.
Material is an important consideration in the resonant structure of the cabinet, which is why some manufacturers use exotic materials, such as the aluminum cabinets of the Magicos referred to in the above post. And some use different materials in different parts of the cabinet to spread resonances and to add some degree of economy to the equation.
Although most speakers are made of MDF (medium density fiberboard) which is generally cheap and may be comparable to the cost of some drivers, the labor in constructing and veneering the cabinet is the more significant expense in the finished cost of most speaker cabinets. My guess - and it is just that - is that most cabinets well exceed, by serveral times, the cost of the drivers in them. And this is most certainly true of those with exotic materials and unusual construction techniques.
But in the end, knowing if the eggs are brown or white does not tell you a lot about the finished omlette. Listen without predjudice to various speakers and pick the one that most closely matches the paradigm of live music that exists within your mind.
