• Series capacitor. Put a capacitor (with its ESR) in series with the driver, next to series resistance, in any enclosure type.
• The port length and port air speed calculators have been rebuilt to be clearer and quicker to use.
• F3, F6 and F10 now find the real roll-off rather than a dip in the response, and horns and bandpass boxes get upper and lower markers. Their settings sit under Advanced, and the panel can be pinned beside the chart.

• Choose which emails you get from your account page, with one-click unsubscribe.
