Contents of the Data Package:

A) FRD Folder

This folder contains on-axis to 45° off axis frequency response data for the driver in open-standard FRD 
format.

All data measured at 2.83Vrms at a distance of 1 meter. All FRD data files include 
nearfield measurement data below 450 Hz. Smoothing is 1/24 octave.


B) GRAPH Folder

This folder includes PDF-format graphs for frequency response and impedance response 
data, plus parameter measurements. PDF files include vector-format graphics for 
scalability/zooming and reprinting.

Frequency response graph is produced using Dayton Audio OmniMic software. Off-axis 
data is included in the frequency response graph as follows:

Black trace: On-axis

Impedance response graph is produced using Dayton Audio DATS software.

C) TEXT Folder

This folder includes text-format data exported from DATS software, for import into 
DATS or CLIO software.

"_dats" = text-format data exported for DATS software
"_clio" = text-format data exported for CLIO software

Text files include impedance data and Thiele-Small parameter data.

D) ZMA Folder

This folder contains impedance response data for the driver in open-standard ZMA 
format.

Impedance data measured in free air at 0.280 Vrms (1/10 watt) using DATS hardware. 
All drivers are exercised for minimum of 8 hours at 60 - 70% of Xmax and allowed to cool to room temperature before measuring 
parameters, to prevent effects of suspension creep and provide accurate data.

Compression driver impedance is measured without horn installed.

Support:

If additional support is needed, or if a problem with the data is discovered, contact
info@daytonaudio.com for assistance. Please include the affected driver model, and 
the name and version number of the software you are using to work with the data 
package, if applicable.

In critical performance applications, please check for the latest revision of this 
data package online before using, and discard all previous revisions.
