the necessary data to calculate the proper box and port size. We have also provided the dealer with several opti- mum enclosure dimensions.
Connection
Speaker Cable
Speaker cable is not supplied with these subwoofers. We strongly recommend using a high quality speaker cable to connect your subwoofers to the amplifier. Your Sound- stream dealer has a variety of high quality speaker cables; ask for their recommendation.
The Soundstream Reference Series Subwoofers have been supplied with premium connection terminals. These termi- nals do not require any type of wire fitting.
CAUTION: Before connecting speaker to the woofers, be sure that the system’s power if off!
Proper Phasing
When connecting the speaker cable to the subwoofer, be sure the positive terminal of the amplifier is connected to the positive terminal of the speaker, and the negative terminal of the amplifier is connected to the negative terminal of the speaker.
The terminals of your subwoofers are Red for positive (+) and Black for negative. Speaker cable is typically coded by color or by markings on the jacket.
If you have any questions as to whether your subwoofer is in phase, verify by ear. The correct polarity produces the most bass; incorrect polarity produces a strangely dislo- cated sound image on mono material. A positive (+) DC voltage applied to the positive (+) terminal will produce a forward excursion of the cone.
Crossover Points
If you are using these speakers as a subwoofer, you will want the crossover point to be set at 100 HZ of less. If you are using them as a woofer, set the crossover point at 1000 Hz or less. The optimum crossover frequency choices depend on three factors: the slope of your crossover network, enclosures used for your subwoofers, and the acoustics of your car. because of interior dimensions, most automobiles have a strong resonance in the 100
By spacing crossover points (that is, placing the low fre- quency crossover point at a lower frequency than the high frequency crossover point), you can create a dip in the output response of the system that will compensate for the peak caused by the resonance. Flat response is the ultimate
result. (If the low and high frequency crossover points were set at the same frequency, the system output might be flat but the audible result would be a severe peak.) With opti- mum crossover settings utilized, equalization is often unnecessary. (The fewer links in the audio chain, the better.)
