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.

Foreword:
Rather than discuss only the performance of the enclosed subwoofer, I want to present some more, detailed information that not even some manufacturers are able to obtain. I will be using my own Klippel Distortion Analyzer and software modules to extract raw subwoofer driver data so we can assess the raw driver performance. This is telling because, simply put, if you start with garbage you will never achieve anything better than garbage. It’s always nice to know what is at the base of a system and this can help determine potential pitfalls in design and use.
