This is true. I was just checking for a pulse. No big deal either way, plus the PE forum is a bit of a fun circus to peruse once in a while.

I've bought some drivers from Bob before and he was very responsive. Better to bring new drivers to the market and take care of paying customers first.

The tweeter thread has turned into the Inquisition. Never fails...

I see there's been some discussion at the parts express forum about this driver's measured specs. Does anyone have any listening impressions or done any builds yet aside from Mark's?

Hi,

In addition to those who have heard the drivers here (and all are welcome to come and listen) there were some comments after the recent DIY event in Ottawa.

DIY OTTAWA WINTER 2012

There were also some others in that thread so please have a look.

Bob

yes.

baffle is about 3x4'. no compensation for baffle step. you can get a better feel for the low end response (negating baffle step) in the HD test where the mic is 1/2m.

sim'd in Edge, the result of BS is exactly as it is measured. one day I'll start merging NF/FF but I honestly don't do it because of the increased time. i put the information out there so people understand it and hope that it is sufficient.

I just had a look at the spec sheet for the LD25x. How was this thing measured? How is there a "measurement blip" at 950hz??? That's a strange place to have a blip. And what kind of blip is it. If a flat IB, then it's not diffraction. It seems much to high of q to be diffraction also. If it's a reflection, it could be gated out below 500hz easily. And if it wasn't gated, it would occur at more than one frequency.

It's a reflection as mentioned in the spec sheet.

Measurement conditions were not optimal. There were two reflecting surfaces almost exactly the 950 hertz wavelength apart from each other, and I kept getting a nasty bounce.
If I measured in close it disappears but I don't believe in publishing perfect curves for the sake of marketing. Top that off with loosing all the data on my computer due to a mother board failure and what you see is what I had to work with at the time. I will replace the measurements with ones that will keep you happy. I have a spanky new measurement puter as of last week!
