In Reply to: Hyperion and Other SF Fans: How do I measure distance from the Signums to the wall behind them? posted by jaybar on September 22, 2001 at 09:30:46:
I'm a former Signum user.I assume you are wanting to determine the distance in order to calculate the effect of the backwave bouncing back from the wall on the bass output.
The distance will depend on which frequencies are concerned. The really low frequencies around 50- 35 Hz will emerge from the port on the back, so the backwave will merge with the port at these frequencies. For these low frequencies, measure from the port to the back wall.
The upper bass frequencies from 50Hz upwards will emerge from the mid bass drivers, so the backwave will merge with the driver at these frequencies. Measure from the cone of the driver to the back wall as far as these frequencies are concerned.
