Judging by the information above, we can draw several conclusions. L e halves(the inductance of the voice coil).V as doubles (the equivalent compliance in liters).R e halves (the DC resistance and the impedance as a result).Parameters that change when adding another speaker in parallel : L e doubles (the inductance of the voice coil).V as doubles (the equivalent compliance in liters.R e doubles (the DC resistance and the impedance as a result).
Parameters that change when adding another speaker in series : Depending on how you wire the speakers, in series or in parallel, some parameters change in different ways. When you plan to use 2 identical speakers in the same enclosure, some parameters cha nge, and most notably, some retain their original value. Then, we can move to the isobaric configuration. First of all, let’s see which parameters change when using 2 speakers in a standard configuration. Anyway, the isobaric setup implies using 2 speakers. I will try to clarify things along the way, if it get’s too confusing. If you want to refresh your memory, check out this article : However, if you want to dig deeper into the subject, you need to be familiar with the T/S parameters and how their values are affected by the isobaric subwoofer box design. Even if you don’t have this know-how, you can still understand the conclusion. Back to the rootsīefore we get to explain how the isobaric design works, we need some basic understanding on Thiele / Small parameters. We shall see how this affects the parameters, and what are the pros and cons of an isobaric subwoofer box design. As a result, the pressure in the small chamber remains constant. As the speakers move, they do it at the same time and in the same direction. The main idea of the design is that you have 2 identical speakers, and 1 small chamber between them. Therefore, isobaric stands for “equal pressure” or “ constant pressure“.
The term isobaric is made by two parts : iso = equal and baric = pressure. In reality, it’s really rather simple, after you understand how it works.
An isobaric subwoofer box design sounds like something that only an experienced engineer can grasp.
