[q] drivers from an old TV
I picked up 2 drivers from the old TV (phillips projection tv similar to this
http://download.p4c.philips.com/file...37_dfu_aen.pdf) how do I determine the characteristics of the drivers -- so that then I can calculate out the enclosure for DIY build ? is that even doable (I can post pics of the drivers) |

You'll need something along the lines of a WT-3 (Woofer Tester). Without something of the sort, there's really no way to tell what the parameters are for an appropriate enclosure. Maybe someone can help by finding a spec sheet about the speaker. Pictures of the front and back, including any printing on the magnet, might help.
Sorry I couldn't have been at least somewhat helpful. Mike

OK, I just found something that might be helpful. If you are a little handy, you could throw on of these together and see what you get.

Look to the size of the TV as a guide, i.e. too big to bother, so OB or at least a relatively large ~aperiodic cab around 2-3 ft^3 and preferably as a TL. Note too the power supply specs is only flat from 100-10 kHz at 5% distortion, further confirming a typical TV's high Fs, Qts driver.

attached are the front and back
(took me a while to realize that the upload does not resize pics automatically, and instead I had to it) the back has something written on it, not sure if of any importance thanks in advance for the suggestions |
