The AudioGraph® PowerCube® illustrates dynamic power capabilities of an amplifier. The PowerCube® tests an amplifier's ability to deliver linearly short term current into capacitive and inductive (not just resistive) speaker loads. These tests are designed to mimic an amplifier's ability to perform under real-world 4-ohm speaker loads. DO NOT follow the impedance loads illustrated in the charts - refer to your amplifier's owners manual for minimum "ohm" loads.

What is a PowerCube®? The PowerCube by AudioGraph is a specially designed test device that simulates a real speaker load playing a musical signal. Rockford Fosgate utilizes the PowerCube to show our customers an amplifier's performance in a real world environment, NOT an amplifier's unrealistic power rating into a laboratory load resistor. It is not possible to "tweak" the test to make an amplifier look beter or worse.

The device tests at (20) different impedances, not to see if the amplifier can drive those impedances of a loudspeaker, but to get the current draw on the amplifier to a level where it approximates the current requirements of a single 8Ω speaker. If an amplifier's PowerCube shows obvious problems and is not "cubic" in appearance, then that amplifier really will not drive an 8Ω speaker correctly, let alone a 4Ω or lower impedance load. This should be an easy test for a high quality amplifier to "pass". The test asks the amplifier to deliver high current for 20 milliseconds.

An amplifier that will not produce a "cubic" appearing cube almost always has power supply, protection circuitry or other circuit design problems or shortcomings.

If the PowerCube is relatively "cubic" in appearance, and the power expressed almost doubles as the load impedance is halved, then the amp should be able to adequately drive a normal loudspeaker, and will obviously be a better choice for lower impedances as well, when compared to an amplifier that does not produce a "cubic" cube. RF beleives that the information gleaned from testing with the PowerCube is valuable because it accurately predicts the output capabilities of a given amplifier, and perhaps even more importantly, the ability of an amplifier to drive a loudspeaker correctly. It shows problems in areas of amplifier design such as oscillations due to reactive loads, or inhibitive protection schemes that are not obvious during other test methods.

The PowerCube is Fair, unbiased and always accurate!

READING THE TEST AND CUBE QUICKLY

Figures 1 - 6 are taken from the PowerCube owners manual. All amplifiers should strive for Figure 1, the Perfect Amplifier. It's very hard to achieve a Figure 1 type cube. Look for them, perfection is rare.

Figure 1.
Perfect Amplifier
This amplifier works as a perfect voltage generator and is not affected by battery voltage, impedance or current demand.

Figure 4.
Current Limiting
This amplifier probably has too few output devices. To protect them, the amplifier has an electronic protection circuit which turns off the amplifier at "dangerous loads."

Figure 2.
Good Example
This is an amplifier with typically good behavior. There are some low impedances losses, but the PowerCube is still cubic.

Figure 5.
Oscillating
This amplifier is not stable at certain reactive loads. As a result, the distortion is always over 1% THD and the resulting output power is 0 watts.

Figure 3.
Poor Power Supply
This amplifier's power supply is too small or has too few output devices and cannot produce enough current in low impedances. As a result, the dynamic output power gets lower in these impedances.

Figure 6.
Poor Protection Circuitry
This amplifier is designed for higher impedance application. Subsequently, it shuts down into low impedance loads.

Legal Agreement

*	Submission Policy: Rockford Corporation “Bright Idea” Policy Statement Thank you for your interest in submitting an idea or invention to Rockford Corporation (“Rockford”). Each and every year Rockford and its affiliates and subsidiaries receive a significant number of communications containing ideas and suggestions for its use. These ideas relate to new inventions, new products, product names, advertising campaigns, marketing strategies as well as other matters relating to Rockford’s business. For convenience, we will refer to all types of submissions as “ideas” or “submissions.” As a company founded on providing innovative new products to its customers, Rockford greatly appreciates these submissions and the interest in Rockford and its business. However, Rockford has access to many ideas through its extensive experience, research activities, employees, independent contractors and other sources. It is, therefore, likely that any idea submitted is already known or available to Rockford. As a result, Rockford finds it necessary to set forth a uniform policy concerning submitted ideas. Rockford wants you to protect whatever interests, if any, you may have in your submission before disclosing it to us. We cannot do that for you so you will need to do your own research and, if you choose, consult with an attorney so that you fully understand your legal rights in your submission – or more likely the lack of such rights. At the same time, Rockford must also protect its interests and avoid misunderstandings or disputes with submitters if Rockford products, product names, advertising campaigns, or marketing strategies might appear similar to ideas or suggestions submitted to Rockford. For this reason, we will not consider any idea submitted unless the submitter follows the process outlined below and provides a signed “Submission Release.” [www.rockfordfosgate.com/brightidea/] Most ideas and suggestions submitted to Rockford are not protectible by patent, trademark, copyright or other laws and are submitted without any thought of compensation. While Rockford certainly appreciates the enthusiasm with which these ideas are given, you should understand that Rockford does not usually act on such proposals. In rare situations, the persons making the submission may have a unique product or plan that Rockford is interested in further investigating. For that reason, Rockford has created a two-tier process for idea submissions. 1) SUBMISSION FOR NON-PATENTED, NON-PATENTABLE OR UNREGISTERED IDEAS, MATERIALS, CONCEPTS, NAMES, PROGRAMS AND LIKE MATERIALS. [WWW.ROCKFORDFOSGATE.COM/BRIGHTIDEA/] i) What’s Included. This form is essentially for any ideas, materials, concepts, names, programs and like materials that are not patented, patentable or registered with a government entity charged with registering and protecting that type of material. ii) How to Submit. All initial ideas must be submitted through either the “Bright Idea” tab on Rockford’s website [www.rockfordfosgate.com/brightidea/] or by mail to: Rockford Corporation Bright Idea Submissions c/o Marketing & N.P.D. 600 South Rockford Drive Tempe, Arizona 85281 iii) Submission Requirements. All submissions must be in writing and must include a signed Submission Release. [www.rockfordfosgate.com/brightidea/] The Submission Release is binding so do not sign the agreement or submit your idea if you do not understand the agreement or disagree with any part of it. The Submission Release must be signed and submitted by every person, business, or entity that helped create the idea or that may have an ownership interest in the Idea (or both) at the time the Idea is submitted. iv) Review and Return of Materials. Rockford will review submissions from time to time on no particular schedule. You should understand Rockford is not obligating itself to review, consider or use any or all of your submission. If you provide a self addressed envelope with sufficient postage (or a return email address if the submission is purely electronic), Rockford will try to return your submission to you and inform you of whether it is interested in using your submission, but Rockford is not obligating itself to do so. Please keep a complete copy of anything you submit. Do not submit unique or one-of-a-kind materials because Rockford is not liable for their protection or safe return. v) No Expectation of Compensation. Most importantly, unless you have a patented or patentable product, do not submit any Idea if you expect to be compensated, paid, rewarded or recognized for its use. 2. SUBMISSION FOR PATENTED, PATENTABLE INVENTIONS, COPYRIGHTED WORKS, REGISTERED TRADEMARKS, NAMES AND LIKE MATERIALS. [WWW.ROCKFORDFOSGATE.COM/BRIGHTIDEA/] i) What’s Included. Though rare, there are certain situations in which Rockford may be interested in further exploring a submitted idea. This will almost always be limited to situations involving a patented or patentable product or, in even more rare situations, for other materials protected by intellectual property laws. If Rockford is interested in pursuing discussions, a representative will contact you directly. ii) How to Submit. All initial ideas must be registered through the “Bright Idea” tab on Rockford’s website [www.rockfordfosgate.com/brightidea/] with all documentation sent by mail to: Rockford Corporation Bright Idea Submissions c/o Marketing & N.P.D. 600 South Rockford Drive Tempe, Arizona 85281 iii) Submission Requirements. All submissions must be in writing and must include a signed Submission Release [www.rockfordfosgate.com/brightidea/] and a copy of any and all registrations or applications for intellectual property protection. The Submission Release is binding so do not sign the agreement or submit your idea if you do not understand the agreement or disagree with any part of it. The Submission Release must be signed and submitted by every person, business, or entity that helped create the Idea or that may have an ownership interest in the Idea (or both) at the time the Idea is submitted. iv) Review and Return of Materials. Rockford will review submissions from time to time on no particular schedule. You should understand Rockford is not obligating itself to review, consider or use any or all of your submission. If you provide a self addressed envelope with sufficient postage (or a return email address if the submission is purely electronic), Rockford will try to return your submission to you and inform you of whether it is interested in using your submission, but Rockford is not obligating itself to do so. Please keep a complete copy of anything you submit. Do not submit prototypes or equipment of any kind during this phase. If Rockford is interested in exploring your idea, it will request any such materials from you at a later date. Rockford is not liable for the protection of or safe return of anything you submit. v) No Expectation of Compensation. Despite the fact you believe you have a patented or patentable product or other registerable and protectible materials, Rockford, by reviewing your submission, is not in any way admitting that you have such rights or agreeing to compensate, pay, reward or recognize you for your submission. If Rockford is interested in further investigating your submission, it will contact you directly so that mutually agreeable arrangements can be made to protect both parties should negotiations for purchase or license of the submission ensue.
