Audio Development SW800 8-Inch Woofer Review

YouTube Video Review version:

Information

Before I dive in I want to note that this is a dual voice coil (DVC) woofer with dual 3.2 Ohm coil configurable in parallel or in series. I have tested and provided the T/S parameters with the coils wired in series and also in parallel. However, based on a poll I created on my Facebook page where I asked if people prefer to run a DVC woofer at a higher or lower load where over 80% of the replies indicated “higher load”, I only tested the woofer at the higher series load of 6.4-ohm nominal for frequency response. However, the linear excursion limits are practically the same between the two sets (the Bl, Cms, and Le curves do not change) and, thus, I only provide the results of the series testing.

Information

Before I dive in I want to note that this is a dual voice coil (DVC) woofer with dual 2 Ohm coil configurable in parallel or in series. I have tested and provided the T/S parameters with the coils wired in series and also in parallel. However, based on a poll I created on my Facebook page where I asked if people prefer to run a DVC woofer at a higher or lower load where over 80% of the replies indicated “higher load”, I only tested the woofer at the higher series load of 4-ohm nominal for frequency response. However, the linear excursion limits are practically the same between the two sets (the Bl, Cms, and Le curves do not change) and, thus, I only provide the results of the series testing.
