My friend the photo up above are the Sachiko double-back-loaded horns I have been using with various single, fullrange, drivers since 2008. I've used and removed Fostex FE206E, FE206ES-r, FE208ES-r and Lowther DX4 drivers. I had everyone of those speaker's cones treated ---{except the FE208ES-r drivers}--- with a special, proprietary, 7-step treatment that greatly improved their sonics! But I was never satisfied with the sonics until I installed Dayton PS220-8 drivers with the cone treatment applied. I highly suggest:
1) Forgetting those Madisound BK-20 cabinets.
2) Use the Dayton PS220-8 instead of Fostex FE206EN drivers.
3) Use the Frugal Horn link below, click on the word Plans below the words Spawn Family and look for Kirishimas.
4) Build the Kirishima which replaced my Sachikos and were meant to use the FE206EN, like my Sachikos were meant to use the FE206E drivers.
As I stated up above, I use Sachikos with Dayton Audio PS220-8 single, fullrange, drivers that same cone treatment applied and I'm amazed at what I hear every time I turn on my audio system! With these treated PS220-8 drivers in the Sachiko cabinets I can play something such as small ensemble playing chamber music or Guinnevere by the acoustic group Crosby, Stills & Nash at low SPLs and hear all the inner-detail, delicacy, correct harmonic tone, color & timbre that one usually purchases single fullrange drivers in horn cabinets to hear.
Yet on the very next cut I'm able to play some seriously loud Progressive Rock music such as Perpetual Change by Yes at 100dB+ SPLs and I can still hear that same inner-detail, delicacy ---{if there's any delicacy in the music to be heard}--- correct harmonic tone, color & timbre plus with huge, wide dynamics and lightning fast transients! The music somehow retains a sense of ease, is crystal clear and without the slightest hint of any "Lowther Shout" or sense of driver strain one often detects when single, fullrange drivers are played too loudly!
How many speakers do you know that can do powered by a 40W/ch, SET tube amp and sound great when playing both types of those musical genres? This Sachiko/PS220-8 combo sounds like you're listening to a pair of Quad ESL speakers, but Quads with a 95dB sensitivity rating & much, much better bass & treble extension! That analogy will give you just a hint of an idea of what type of sound quality I'm talking about. In all honesty this sound really almost must be heard to be believed. The best part is these speakers are easily duplicated. So anyone can either build a pair of these exact same speakers for themselves or have a pair built for them, just by clicking on the link Frugal Horn below and downloading the Kirishima plans! Of course you can use the Fostex FE206EN "if" you prefer, but I wouldn't...
I hope I've helped you with any questions you might have and please feel free to ask me any additional questions here on The Asylum or via private email if you prefer.
