I posted this pic in another thread. The 15/6/1 dominated too much to make a really good sonic match IMO. The whole stack sounded very good though, don't get me wrong. Note that this is not really a fEearful 15/6 either...just a near cousin. I'm going to keep working on this idea, since I can! I've totally reworked the top box in the last few days, so my impressions may be different when I re-try this combo.
