how to increase piezo power handling
type: item
description: How do I increase the power handling of the ksn 1038 without changing the overall efficiency? If I put 2 of them in parallel, the overall efficiency will go up by 6 db. If I put 2 of them is series, the overall efficiency will not change correct? Because doubling the impedance decrease the efficiency by 3db, and doubling the radiating area increase it by 3db so net gain is 0. However these piezos act like capacitors at hight frequency that is why you can use them without a filter capacitor, but would putting 2 of them in series result in 1/2 the capacitance at high frequency and therefore shifting the xover frequency upward?

Put 'em in series
type: item
description: You can increase power handling withouint increasing voltage sensitivity by putting two of them in series. When doing so, keep them close together and align them vertically on the baffle rather than putting them side by side.
