This is typically accomplished by having big holes in the sides of the frame just below the spider attachment shelf. All sub's are designed to have some sort o…, A: Good quality, and a wide range of audible tones. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. This reduces thermal compression effects and enhances reliability.
