  1. Horn Build

    The real challenge of this build comes from trying to turn a 3D CAD model into a physical object. The benefits of the CAD modelling are huge as they largely remove the need to do math for some of the complex angles in a 3 dimensional space however they do…

  2. Horn Modeling

    Given the complexity of designing a Synergy Horn very few programs are available to model the predicted response. HornResp will work to some extent but given the complexity only Akabak really has the power to do the job. Unfortunately Akabak will be unapproachable to many people unless they have a…

  3. Horn Design

    Whilst reading about various DIY attempts at designing a Synergy Horn I came across an interesting quote that said that because you are designing in a 3D space something like a simple 60x60 degree horn does not contain any easy 60 degree angle cuts. Given this fact I thought why…

  4. Loudspeaker Frequency Response Measurement

    This tutorial aims to show you how to perform a loudspeaker frequency response measurement using ARTA for a two-way loudspeaker system. Required Equipment A sound card (either internal or external) which has two line-out (left and right channels) and two line-in (left and right channels). An amplifier (5W+ is more…

  5. Replace a Tweeter Voice Coil

    If you are reading this is it is likely you are kicking yourself for destroying a perfectly good tweeter. Don't worry. Fortunately Seas expected this kind of reckless behaviour and provides replacement voice coils for it's tweeters. In this tutorial I will show you how to replace the voice coil…

  6. Crossover

    This speaker uses the same bass driver crossover as Troels Gravesen's Eekel speaker which creates a third-order acoustic rolloff. The tweeter has to be heavily padded down to meet the low sensitivity bass driver and also uses an acoustic third-order rolloff. The crossover frequency is just under 3000Hz which is…

  7. Enclosure

    The enclosure for this speaker is a simple box of approximately 4.8 liters volume. Due to the size it does not need bracing and using 18mm MDF of equivalent results in a very solid and heavy little box. Thirty minutes from my house is a specialty loudspeaker cabinet maker…

  8. Drivers

    Seas Excel T29CF001 (E0038) 29mm fabric dome tweeter The Seas Excel T29CF001 (E0038) is a top of the line 29mm fabric dome tweeter. The faceplate is slightly concave creating a moderate horn loading which combined with a very strong Neodymium Iron Boron magnet system makes this tweeter extremely sensitive (Seas…

  9. Design Goals

    The ea loudspeakers are two-way loudspeakers employing the Seas Excel Nextel drivers with a second order acoustic crossover. As this was primarily a learning project for me my design goals for this project were simple: take high quality drivers and work them into a simple two-way loudspeaker utilising digital crossover…
