  • What to do with these drivers? (Pics)

    I found this centre speaker in Dick Smith's on special for $28; turns out they had none left in stock, so the guy sold me the display for $20. A bargain for down here in Tassie, it first retailed for $75.

    I took it home and unscrewed one of the (12cm) woofers after seeing that they were all working and not damaged. As you can see below, a very simple design with cast frame, no venting what-so-ever and a poly-coated paper cone. They need breaking in, but they should be two good, budget woofers.

    They seem like Hi-Vi drivers but without the aluminium cone. The tweeter is useless at this stage since there’s only one, and I haven’t found it particularly interesting to listen to.

    Now, what to do with them? I originally intended to get one driver to make a “sub”woofer to go with the two (silver) 40mm drivers from Jaycar, but since there’s two woofers, I was wondering if I should make a two-way instead. (I can't and don't have any measurements!)

    The options are:

    Jaycar drivers as stereo satellites, both DSE woofers as sub.

    Or: two-way bookshelves with DSE woofer and Jaycar driver.

    Note: Everything was set up for a 2.1 system: 1W + 1W for stereo, meagre 5W mono chip amp for sub. (It’s DIY cheapo, this project). I may need to build another amp if I do the bookshelf.

    Not trying to pick-
    That's a stamped-frame, not cast. If it was a Hi-Vi, the buck-cup would be black.

    I'm sure Andy G. could help you out down under...as well as a few others that post here.

    They definitely look intriguing!

      Actually, regarding the measurement, how accurate is measuring T/S parameters using Rod Elliot's method(s)? It seems all you really need is a 10 Ohm, 1% resistor, a multimeter (and plastic bag, rice, etc.)

      As for the drivers, the lipped frame looks similar to the Hi-Vi bs series, but I think are DSE's "Daytons" if you like...

      The bookshelf idea is looking more appealing (The drivers' appearance is too good to be stuffed in the corner! :p), which means measurements might be more important.

        Not sure I can at all. I've never seen that particular speaker or driver.
        (Rare for me to go to DSE)

        Not much I can suggest, sorry. :o
        If people want to listen to wiggles, that up to them....

        I prefer music.

          I guess I can experiment...:p

          Do you think I should pursue this method of measuring T/S parameters?

          I don't think I mind spending the time...

            I used to do it that way before buying a woofer tester and it works fine; just time consuming and tedious.
