Default Freq Response Measurements of PHL drivers

Has anyone made Frequency response measurements of any of the PHL drivers? I can' t find that info anywhere.

Also, if anyone has made these measurements of 2 or 3 way speakers with a PHL driver in it could you please post a link to it?

Thanks
Alex

Im actually a little disappointed... Those graphs are pretty rough. I expected those PHL drivers to be a lot smoother than it shows.

Now I just have to find the measurements for some Lambda acoustics 10 and 12 inch drivers and im set.

Thanks
Alex

At least we now know why PHL doesn't post curves on their website!

at least these are very honest graphs, not those delivered by thh compagnie wich are most of the times smoothed or scaled to a almost unreadable db scale. With that in mind these graphs actually look pretty good.

Most of the graphs show a lower spl at the lower end (150-500 hz) would this be due to the baffle step, diffraction?

Thanks

Actually I looked at the PDF on the link to the PHL1120. It looks pretty flat when mounted on a 15by8 baffle... The 1220 looks alot more peaky.

PHL 1340 in box. But dont remember the dimensions.

IMHO PHLs are very good drivers but only for midrange.

It's odd that the PHL charts don't look pretty like Focal, Seas, etc.,
but for some reason we always choose the PHL over the other
drivers during blind auditions. The finger points to PHL when
it comes down to sound quality.
