Take a sweep with REW and see what your response look like. Most receivers these days have flexible tone controls and equalizers built-in. You might be able to make some improvements with them, depending on what REW shows you. Post a graph and some details on what kind of equalizing your receiver is capable of, and I’ll see if I can make a recommendation. If you want to EQ full range (i.e, with an outboard equalizer), you’ll want a good-quality model – read “not cheap.”
