I was so pleased to get the owner`s manuel within one hour! Thanks again.
Regards

Finding the owners manual for my Pioneer CRWM62R is greatly appreciated. I had searched several other web sites with no success. Although my manual was not listed on your site for immediate download, I recevied an email within a few hours that my ower's manual was posted for me. I had no difficulty downloading the manual for my 20 year old multi-cassette player. Owner Manuals provides a service that is valuable, easy-to-use, accurate , efficient, and priced fairly. I thank you.

Excellent manual - just what I needed. Although currently available only in German, their are lots of pictures which makes it all very clear.

Connecting Your Subwoofer to Your Amplifier JBL GTO Series
JBL GTO Series subwoofers are available in two different con�gurations: as a single 2-ohm voice coil or as dual 2-ohm voice coils. Depending on the ampli�ers you are using, you may use either single-voice coil or dual-voice coil subwoofers in singles or multiples to maximize the power available from your ampli�ers. To achieve the maximum ampli�er output possible, you should design a speaker system that provides the lowest impedance that your ampli�er is rated to drive safely. When designing a subwoofer system, consider the following rules: 1. Don�t mix different subwoofer or enclosure types in the same system (use all single-coil woofers or all dual-coil woofers). 2. You may connect the coils of a dual-voice coil woofer in series, but we recommend that you avoid connecting separate woofers in series. The ampli�erdamping factor (the ampli�er�s ability to control the motion of the woofer) is expressed as a ratio of terminal impedance (the sum of speaker impedance, wire resistance and the D.C. resistance of any crossover coil connected to the woofer) to ampli�er-output impedance. Therefore, connecting separate woofers in series reduces the damping factor of the ampli�er to a value less than 1. This will result in poor transient response. 3. You must use both coils of a dual-voice coil woofer connected either in series or in parallel. 4. Most ampli�ers deliver exactly the same amount of power bridged into a 4-ohm load as they do running a 2-ohm stereo load. To design a subwoofer system that maximizes available ampli�er power, keep the following rules in mind: 1. The total system impedance of woofers in parallel can be calculated using the formula: Impedance = 1 1 + 1 + 1 ... w w w

where w is the nominal impedance of the woofer. 2. The total system impedance of voice coils (or woofers) in series can be calculated using the formula: Impedance = w1 + w2 + w3 . . . The diagrams at right show parallel and series speaker connections.
