I like to build a special speaker that is designed for a particular application if I'm going to do the whole cabinet. Just once in a while. Too busy with wood tweeter horns most of the time, and when summer is in the good days I like to be on my boat.

Do you use a sweep, discrete sines, white (or pink) noise or a maximum length sequence for your measurements? If a sweep or MLS, how do you synchronize the input capture with the output signal?

How do you decide on the best places to put your speakers?

In any case, might I suggest that measurement microphones placed as an array of points showing response in the listening area might be more useful than the placements of microphones in room corners.

• To measure or not to measure (and what good is it anyway?)

I agree with you on micing the room corners. It does give a baseline for room mode and depending on results it can show a room anomaly that can be helped by an acoustical treatment. The placement of the speakers is determined in large by where the customer wants them. There is always a little wiggle room and when you evaluate what you hear and what measurements look like you can make a placement change. For the most part the speakers already have a designated place in the home. been good chatting, take care.
