Tannoy System 800 (or CMS8) driver specifications? Anyone have a WT-3?

gripracer · 4th February 2010, 02:32 AM

I have scoured the web for the specifications (most importantly Q, Fs, and Sd) of the woofer and tweeter of the drivers that come in Tannoy's System 800 monitors that were made around 2005. All I can find is the specs of the speakers already in their boxes as a system, like overall frequency response and efficiency and such.

I'm really starting to doubt the specs are out there. If anyone here has them, awesome!

But no one probably does, so will anyone lend me their WT-3 tester? I will pay for shipping both ways and give you a little cash. Let me know if you have one!

Here's what I have in my database. I don't remember if I took any of these measurements personally or if I got them all from elsewhere.

Tannoy 2046 8" Dual Concentric:

Znom: 8.000ohms
Revc: 4.400ohms
Sd: 196 cm^2
BL: 7.5253
Vas: 34.7
Cms: 635.4423 um/N
Mms: 23.2575g
Mmd: 21.6785g
Fi: 40.062Hz
Fo: 41.400Hz
Qms: 10.550
Qes: 0.470
Qts: 0.450
Pmax: 100W
Hvc: 10mm
Hag: 5mm
Xmax: 2.5mm
Cmx: 2.5mm
Cmo: 1mm
No: 0.51%
SPLo: 89.08dB
SPL 2.83V/m: 91.10

FYI, these drivers were also used in the I8AW all-weather speaker.

No problem. What are you planning to do with them? I'm using a pair of 2046's from CMS-8's as surrounds in my main system (modified 12 DMT II's up front).

I think an MTM with the 2046 and two sealed Peerless SLS10's would be an awful lot of fun, myself. Coherence and incredible midbass dynamics in one package.
