Off-screen response problems are often a result of a system with a large quantity of woofers. In some situations, this may be a desirable result. If so, look for smooth transition from octave to octave. If your goal is competition, you must have all the bands on display at one time. This problem is very similar to the Output Level Incompatibility Problems discussed earlier.

Non-Equalizer Solutions

Since this situation is similar to Output Level Incompatibility Problems discussed earlier, the solution to this particular problem is the same. First try balancing the output between the midrange and tweeter. For this example, reduce the level of the midrange. If you have passive crossovers between the midrange and the tweeters, increase the level of the tweeter. If you have an active system, balance the level between the midrange and the tweeter by raising the level of the midrange. Once you have achieved a balance between the tweeter and midrange integrate the level of the woofer by similar tuning techniques.

Equalizer Solutions

Use the DEQ 30 as a cut only device to try to smooth out the non-linearity of the system. Cut frequencies gradually starting with the center point of the problem area. Do not cut the centered band to get the frequency response to the flat position for it will dip below when you change adjacent bands. Periodically listen to your system during this process to make sure the changes you make do not adversely affect the detail and sound quality of the system.
