As for your judgement scores, you are comparing 2 very different drivers for 2 VERY different intended applications. Take the efficiency readings with a pinch of salt and read up about Hoffmans Iron law. The ratings on power handling are also somewhat off, Fi rate the IB3 based on mechnical power handling not thermal. Thermally that thing will take twice the rated power but in IB drivers the mechnical limitations are primary way of giving ratings.
What you say about IB not having good top end? I play my 15's to 90hz to enforce my 5x7's. If you cant get good output past 45hz, you need to choose a better driver and ditch a class d amp and go with a good class ab amp.
