    Hi everyone, i hope your doing good !!

    I´m a tech enthusiast that live on the edge in this Beautiful but Intriguing Country, Venezuela. Where Music is a must in our culture and I, as a music lover and DiY guy,  plan to start a journey building a pair of DINAS. This will be my First speakers Build and i think this experience will be really nice.

    I´m expecting to receive all the components in about 12 days, so i´m going to start building the wood box according to original plans, but with a little twist on the outside. 

    Thanks to @123toid for making and testing this design, i hope this build goes as good or better as the originals.

    Best Regards.

    Daniel Strauss.

    @djstrauss I’m really excited that you are building the Dinas! Feel free to post a build log off you want. And past pictures when your done! I love seeing others builds!

    Hi, @123toid

    I just want to be clear about the components connection.

    I already saw the diagram and understand this:

    S1 NEG goes to Cap then Cap to S2 POS and Finally to Amp POS.

    This serial connection creates a 8ohm load on Amp POS. Correct?

    Then S1 POS and S2 NEG to Amp NEG.

    This creates the other 8ohm. Correct?

    Then Sub connection is polarity inverted directly on the Amp. 

    That’s it?

    Sorry for my noob assumption.

    Just wanted to be clear.

    With the inverted polarity for the sub, you can always test if the bass sounds weak or normal. If weak you have a null being created and need to inverse the polarity, if not then your polarity is fine! I don’t know the circuit diagrams for the DINAS, but if they are 80hm drivers they will be in parallel for 4ohms. If they are 4ohm drivers they will most likely be in series for 8ohms total.

    Hope this helps. 🙂

    you can either hook it up to the other side of the cap or directly to the amplifier.  It makes the same connection.  But yes, you are correct, except for the resistance rating and serial connection.  Since both drivers have their own ground and positive, this is a parallel connection.  a series connection would have only one positive and one ground hooked up, with the speakers positive and negative wired together.   This maintains a nominal 4 ohm load, however, it does rise to around 8ohms at it’s highest peak.  Without the cap, it would make it a nominal 2 ohm load.

    Awesome, so is he just using a cap on the tweeter? Won’t that tweak the polar response of the driver combination?

    It is just a basic first order crossover on the tweeter.  Any crossover can affect polar response, it all depends on how it is implemented.
