[QUOTE="Frank Koenig, post: 125203, member: 416"] Re: My Current SH46 Settings Here's an update. I threw out the horizontally on-axis measurements that bisect the 2 speaker array.

Having it too bright caused me to turn up the bass shelving to compensate during listening tests and the whole thing ended up sounding like ass.
