| A method of
connecting multiple electrical components such that there is the same current
through each. In loudspeakers, connecting woofers in series is accomplished
by connecting the woofers "positive to negative." Putting two
woofers in series will double the system impedance and system radiating
area. The net result of using two woofers in series is no gain in efficiency.
However, the increase in surface area will reduce the amount of excursion
required to produce a given SPL, and a higher overall SPL can be produced.
