Well, I respectfully disagree that in room tuning is a bad thing. In fact I'm a proponent of in room tuning and virtually opposed to lab and anechoic tuning.

Yes, of course in room tuning is more difficult to do. But. Since we don’t often listen to our speaker inside a chamber or laboratory. We need to have them balanced, voiced or tuned for the rooms we listen in.

If in room tuning was such a bad thing. then they would have all kinds of crazy EQ's, feedback destroyers and various other types of equipment for the balancing of studios, halls, rooms and all other venues including homes, home theaters and cars.

One of the main reasons anechoic testing is good. Is it gives all things an even playing field to compare against. theoretically the chamber in California is the same as in New York as in Sweden. This chamber also gives you a constant to measure any changes or modifications against.

Beyond that. In room testing, although difficult, is a must.

Good luck,

Bill
