Illuminati (1st Degree)

I think I know what the mis-understanding is here. In a BLH design the bass is brought up to match nicely with the mid-treble response. In a typical box design, the bass isn't brought up as much. In order to get a measurably flat response, some sort of compensation circuit is frequently applied to bring the mid-highs down to the level of this bass. This causes a drop in the direct radiators output. The driver itself hasn't changed in anyway, only the signal going to it.

At least, that's what I think this conversation is about.
