  • "Mr. East" nearing completion....

    This was a project for fun, pure and simple, and to see what could come from a decent 2" driver. I chose the TB W2-803SM, and thought for a bit...

    -Wanted more output potential; I had a few extra 60/40 Selenium biradial horn-flares, 3 to be exact.
    -I had this weird plasti-composite 3/8" material from Menards; E*** board (you find the letters to fill in).
    -I wanted *reasonable* bass extension, W2 has 1mm Xmax too.

    I contacted Paul K. for a model with measured data, and it looked good enough to pursue on the bass end. We combined our efforts to produce this:



    Sim uses 1 oz of poly-fill, and I weighed poly-batting to fit the mass-spec and wrap around the interior wall.

    Template assembly:



    Assembled minus side:



    I used the first flare to experiment with fitting of the W2, and then cut the 2nd and 3rd to match the result. Depth varies on build, and flange thickness, so try your own. I 2" Forstnered a hole through the throat to allow full-position of driver in the end. Sprayed flares with Krylon Fusion Hammered Silver. Truck bed liner on the rear of the flare, and there will be gaskets to isolate, and polyfill to further damp the back of the flare volume when this is done.

    1st mockup was measured by Brian at his place to try for a network. Ohhh boy, **!!HONK!!** :eek: Network simmed to reduce honk and level high-end rolloff. 5 cheap parts resultant. Not much acoustic gain from the flare in the end, but it was fun!!



    Here is how she sits currently:



    I have to finish assembly on the second unit, and test the simulated network to verify it works well enough. Plastic cabinets will be painted with Krylon Fusion Satin Burgundy, as the plastic-bond works very well.

    The name results from seeing the Tannoy Westminster, and the TB manufactured in the East; ipso-facto: "Mr. East". :rolleyes: These are a ton smaller, and different than any other DIY project I've encountered or built, and bizarre enough I had to try it!! :D

    I know I'm different, so don't tell me....
    Thanks for saying, "Whuh!?!?"

    That is so cool wolf. Love it. You're a madman.

    Can't wait to hear your listening impressions.

      Heh, looks like you squeezed every ounce of output from that driver.

        I presume your changes got rid of the honk? I looking forward to hearing them, too.

          Tiny TL's... I like it! A pair of those in a bigger box, and you're on the path to a B**e Wave Radio...

            I have to test the filters yet, Paul, so I'm not certain.

            As to the amount of output, it's probably an 87dB nominal, but the measurement was taken at a higher level. These are 85dB on their own without added fixins.

            Thanks for the support, guys! I will be reporting my findings.

                  I really like the look of this Wolf. Very interesting use of the horn for loading. What are you doing, if anything, to reduce the honk associated with the horn loading?

                    That is what the filter will be used for. It's in the FR picture.
                    The 'hill' is the natural response, the filtered is the flatter one.

                          Very Cool Wolf, very cool, I am stumped as to what a Menard's is other than a race car manufacturer but I doubt that is what you meant and am totally stumped as to the "E*** board" could be. Could you give us a little hint? That composite board has me interested in getting my hands on some.


                          Thanks!

                            Okay, I figured out what your Menards is, it is a big box hardware/lumber store, but I can't find out the "E*** board" stuff......

                              Mr. Wolf,

                              I love how you seem to make small speakers sound big. Even if you never posted your name to this one, I think I'd still know it was you that made it.
