Default CV subs

Whoops I forgot to give the model number. They are ATW15's and also on the magnet is C5V.

Thanks

You will have to measure them yourself. It is tedious, but easy to do. One article on how to do it:
http://www.epanorama.net/documents/a...arameters.html

You use your soundcard equipped computer with an audio generator program (NCHtone makes a good free one) and a voltmeter and a couple resistors.

or you can go whole hog and use a free measurement system, called Speaker Workshop (google it).

I have some AT-12's from that era and they measure Fs=20, Qts=0.16 and Vas=360L...

About all I could say about the 15s is that you should expect low Q and High Vas - that's how they get the high sensitivity.
