Description
The SP 218 is a subwoofer designed to make it easy to add more
The enclosure is constructed of top- quality birch plywood with internal braces, covered with heavy duty black carpet and reinforced with
A
Inputs are at the rear of the enclosure and consist of two 1/4" jacks, one
This low frequency enclosure is comprised of two 18" Pro Rider® subwoofer drivers in a vented alignment. The Pro Rider driver delivers superior performance due to its advanced cooling system, large 4" voice coil with
venting for the system, and the molded vents also support the grille.
As the SP 218 does not include a passive subwoofer crossover, input should be electronically filtered for subwoofer applications. In addition, for high power operation, a
Frequency Response
This measurement is useful in determining how accurately a given unit reproduces an input signal. The frequency response of the SP 218 is measured at a distance of 1 meter using a 1 Watt (into the nominal impedance)
Power Handling
There are many different approaches to power handling ratings. Peavey rates this loudspeaker system’s power handling using a modified form of the AES Standard
Harmonic Distortion Second and third harmonic distortions vs. frequency are plotted in figures 3 and 4 for two power levels, ten percent (10%) of rated input power and either one percent (1%) of rated input power or 1 Watt, whichever is greater. Distortion is read from the graph as the difference between the fundamental signal (frequency response) and the desired harmonic. For example, a distortion curve that is down 40 dB from the fundamental is equivalent to 1% distortion.
