I have a box of Monsoon MM-700 drivers collecting dust in the garage.

Was thinking about sending them to eBay, so thought I'd measure them first.

Performance is surprisingly good!

CSD is very poor though; I wonder if there's some 'special' way to measure planar CSD? I know that you can't get a good phase measurement from a planar.

if to close the - 5 db might be part of the filter to compensate for the lows rolling off to early. so you might have over compensated now for a normal listening distance?

Before you get too excited about the frequency response, try doing a measurement off axis at say 45 degrees. This will show you how much beaming (pattern narrowing) that they have.

Well that's a feature isn't it?

No. That kind of response embodies poor "pattern control". It's not usually viewed as something positive.

I disagree. IMHO, there are circumstances where you may want narrow directivity. While the off-axis response of a planar is not as smooth as the off-axis response of a waveguide with a narrow angle, the planar will have a much smaller package.
