any idea what will be the T/S parameters for the bass drivers from ATC.

Just two parameters are more imp
Qts and Compliance

I see their motors are very heavy and beefed up so the Qts has to be too low or Compliance has to be too low.

Is that the ATC SM75-150S (16 Ohms/Re=10.5)?

Looks like Dropbox may be blacklisted from your network (working place or home ?)

It seems that your computer cannot establish a direct secure connection with the Dropbox servers. Could be the NSA listening in on you ( 😛 ) or a proxy.

I have attached it in zip form below; hope that helps.

With Google Chrome, who knows? for years I used Mozilla Firefox, but a couple of years ago it began causing the computer's processor to run at 100%, effectively locking it up and none of its updates has solved the problem nor did uninstalling/re-installing it.

Thanks, appreciate it!

Note: sure it doesn't look like it (besides the lettering stating "SCM20sl"), compare the two. It has a round/circular flange around and something black on top like a waveguide??? 🙁
