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.

After reading lots of material and looking at the specs of both subs, JL 12W7 seems very promising for IB. I am not saying better than IB3 but should give the results similar to IB3.

Also considering that my boot is half full most of the time, I am hoping that it will give me excellent results.

What do you say?

Tried to install it today on the rear deck. Loads of work is involved, but eventually I will get there.
