I am pretty happy with my 4333A's as they have great sound, but have been wondering if ther is anything that I can do to improve them in any way? I know it is a loaded question, but I would like to hear any suggestions. They seem to sound better when I couple them with my L-166's and I was looking for a way to get around this(living room space is a factor )Maybe crossover mods? Should I stay with the mid horns? Also, does anyone use the expensive supertweeters available now?
