Thanks Ian

Will do. I do have a question. In the above post you recommend using a new D8R2425 diaphragm. Speaker Exchange also has the D16R2425 I believe the original In the L300 documentation it has the D16R2425 as the substitute. I did order the D16R2425. Is this correct as the passive crossovers are looking at 16 ohm load?

I saw a video of Steve Guttenberg interviewing Andrew Jones entitled "Measurements won't tell us if we'll like the sound of the music". Very informative. As you have stated above although measurements are important, there is also an art to get the speakers to sound right.

Thanks
