[QUOTE="Hennie, post: 38933, member: 20"] The peak to peak ripple is very typical, which is why anyone should take measures to improve on it. I would be the least concerned about the 25Hz null and give preference to smoothness from 40Hz upwards. Actually, when excluding the 25Hz null the response from 30Hz upwards does not look too bad given that you have not done any optimizing yet. [u]Things you can do:[/u] Move the sub around and measure Add bass traps Allow overlap between the sub and the mains. Measure the result for the sub in different positions. Change the phase switch and low pass filter control for every position and measure. It is a fallacy that the sub and mains cut-off characteristics should be complementary. Room acoustics screws this up and sometimes an asymmetric crossover, or overlap (too high crossover), or too low crossover gives the smoothest response. Do whatever gives you the smoothest end result. Add a second sub. Two subs when moved about for optimum location and each individually adjusted will give a substantial improvement over one sub. Adding a second sub and allowing overlap with the mains is even better. [/QUOTE]
