DIY Coax

edited April 2017 in DIY
The inDIY '18 competition categories got me thinking CHEAP. I heard​ Ani's art nouveau entry(great speaker) and decided to use the miniscule tweeter in a coax. Low n' behold, TB13-1761s and Peerless TC10FG00-04 were merged. Got a FR(22uF cap for the tweeter) and some speaker porn pics.




............. could you hum a few bars.

    Well, well done!

    Awesome. I have been meaning to do something like that, but sloth is my identifying trait methinks.

    I have a signature.

    Nice, and that tc10 has high sensitivity and power handling to boot. WTG Kenny. I am also going to try this out.... Have the parts on the way
  • kennykkennyk
    Glad to serve.

    Oh, one critique.......Mother to solder leads on the TB.........cooked the trace.

    Finally put a second coax together, surprised at the FR.


    Next I got to audition them.

    Is that with any sort of crossover on them? They only need a notch at like 400ish and 8k-10k and they'll be nice and flat.

    Just have a 22ohm cap on the tweeter.

    If it is a cap it would be in farads, and 22uF seems large.
  • ani_101ani_101
    you are right, i got it wrong too!

    I used a 4.7 uF but i was crossing at 7khz. that tweeter should not be crossed lower than 4.5 - 5k, 7-8k is better

    Just had it on for protection, same cap as in the first post.. I was looking for a general FR.

  • greywardengreywarden
    Oh wow, ok, so that's pretty flat with essentially no crossover!

    Decided to use this for Iowa(if it works). The coax will be sealed in 0.62L on top of the DS115(same woofer in the itty-bitty) in 3-6L. This will get on a plane.  :3

    Well, it worked in the itty-bitty. Just not too many small woofs that would work. Hmmmmm, I should look a little harder.  ;)

    Just did some quick sims with some 4"ers and the DS looks best. I'm stuck with it.
    Now if you have any suggestions...........

    Try the Tectonic Elements TEBM65C20F for $14

     John H, btw forum has decided I don't get emails
  • kennykkennyk
    Thanks John, but the DS114 has more efficiency, lower fs, low VAS and I used it before with success.

    hopefully not too late, but you could use this website to make a cone shape that will make the transition from cone to tweeter housing a bit better, make smooth out some of the FR, too?

    The tweeter is 6mm proud. I plan on using an o-ring to fill the gap and hope it will help with wave integration.

    Excellent.  Look forward to hearing these in Indy next year
  • kennykkennyk
    Actually, these are for IOWA. Plan on a larger woofer for INDIY.(as per the rules)

    Would you be performing another "Operation" on these for Indi?

    I will make a "fresh" pair for indiy with larger woofers. Volume was the issue in the last pair.

    Larger woofer that is NOT a Designer series?
