Small Tannoy DCs 1666 Parameters

[David Blue]

Sorry, but 1st post is a question.
I have a few drivers sitting around and I have found the perameters for the 2008 drivers, but I can't get any information from anyone regarding the 6.5" drivers that I believe are 1666, but may be 2040.
Can anyone help.
I am trying to make use of these drivers in a small enclosure.
Thank you

If you have a Mac, you can measure the T/S parameters yourself with FuzzMeasure and the cheap/simple impedance jig described in FuzzMeasure's manual.

It's always better to take your own measurements rather than trusting others'. Even the manufacturer's.

Hi David,

Here are my personal T/S parameters recently measured with Woofertester2 V5.

#1. Tannoy Definition D100 (driver 1666 SN: 468384L)
Re = 4.4522 ohms
Zmax = 33.2435 ohms
Qes = 0.4163
Qms = 2.6921
Qts = 0.3605
Eff = 0.0055
Eff = 89.4378dB @1W
Sens = 91.9830dB @2.83V
Le = 0.3713 mH @1 kHz
Fs = 51.543 Hz
Sd = 0.014103 m²
Vas = 17.862 L
BL = 7.227 N/A
Mms = 0.015 g
Cms = 632.215 uM/N
Kms = 1581.739 N/M
Rms =1.814 ohms
.
#2. Tannoy Definition D100 (driver 1666 SN: 468387L)
Re = 4.2784 ohms
Zmax = 31.0194 ohms
Qes = 0.4222
Qms = 2.6392
Qts = 0.3640
Eff = 0.0057
Eff = 89.5801dB @1W
Sens = 92.2982dB @2.83V
Le = 0.3754 mH @1 kHz
Fs = 54.045 Hz
Sd = 0.014103 m^2
Vas = 16.239 L
BL = 7.205 N/A
Mms = 0.015 g
Cms = 574.788 uM/N
Kms = 1739.771 N/M
Rms = 1.941 ohms

The D100 is a small cabinet about 10,7 L.
Port dimensions :
diameter = 31 mm
length = 67 mm.

Hope it will help.
