I don't know if DVE has test tones. I've been using the RealTraps tests tones that Randy suggested.

For the longest time I reasoned to myself that cascading filters are "bad" so why try? And then I decided to go for it and was surprised at how much better it sounded. I'm sure this has a a lot to do with my bright room. Bass just hangs around in that room even when it's time is supposed to be up.
