    Wolf--Any chance that we could see FR of Before/After the final tweak, which addressed the sibilance issue?

        Re: "Trichotomy"- Painting almost complete!

        Let's just say that I got what I wanted out of the finish this time around, and I will post pics when I get them reassembled. I have to wait a couple more hours before I can apply the clearcoat and wait a few days to final cure.

        Stay tuned!
        Wolf

        Oh yeah- And I will be trying the 'Spiral-horn' port thingy with these too. Just an A/B mostly.

          I'm really looking forward to seeing your latest creation. I saw the photos from Chicago -- very interesting look.

            Re: "Trichotomy"- Finishes and an added tweak...

            Argh!!, but a mild one. The painter's tape took off a bit of clear-coat in spots. I'll wait until Spring to finish it, or touch it up/repair. It may be that the Polycrylic and Chalkboard paint weren't the most friendly bonding paints, but only a few places were less than ideal.

            I used my usual Duplicolor High-Build Filler Primer, and then proceeded with Krylon chalkboard paint for a thicker application and semi-flat finish. Then I topcoated with Polycrylic Spray.

            Waited a couple days, and then masked the entire cabinet off to apply the color onto the side-panels. I used Scotch's Blue Painter's tape this time (when I've always used Duck before, but the Scotch had a less-strong adhesive so I figured it would pull off easier, and it took some clear-coat off the chalkboard paint with it), since I had so much area to cover.

            I then lightly hand-sanded the inner panels, and wiped out the dust. I applied Rustoleum (only maker that had the colors, or it woulda been Krylon) Antique Brass Metallic, waited for it to set, then applied American Accents Stone "Mineral Brown" on top. I applied about 2-3 coats of the Brass, and same on the stone, so the brass sheen comes through the rich stone-colored texture. It looks really good against the black majority, marble baffle, and kevlar/paper midbasses.

            Tweak:
            I'm currently awaiting E6000 adhesive to set on the rear of my BG's to hold the 3/8" thick sport-florring rubber pads (shredded tires). This was a tweak I did in the Attitudes on the chamber cups for the Usher midranges. I applied a square there that had the corners touching the perimeter, and that is how most had heard them. It had such a profound change on the sound that it must have damped the plastic's resonances that were formerly emitted under operation. While I know that the BG's likely have some damping internally, I couldn't let it go completely without trying this to appease my mind of probable causes. (Also let it be known that I had to seal my BG's with E6000 previously; both from the cabinet volume to the cap and through the faceplate. Just a perimeter application is all that was needed there. It squeaked without it.) I figured the dark character typically established in the Neo3 could be nothing more than an undamped chamber or one that oscillated with internal pressures.

            I'll let you all know my findings on this! Pictures will be posted soon....

            Later,
            Wolf

            In addition, a note from Mark at Meniscus about their preference in mounting the BG Neo3:

            We like to pop
            the stock back cup off and use a deeper, sealed cavity behind the tweeter
            - about 2 inches depth, built up from behind the baffle with scrap wood. >Yes, usually a bit of Dacron will do for fill.

            Regards,
            Mark

                That is one crazy lookin' speaker, man, looks good, though.

                You can barely see it, but I'm on a 42" screen right now, lol.

                  I overlayed the FR plots of before and after the tweaks on the topend of the response, since PassingInterest asked. Its change includes both the resistor and zobel across the BG. You can see the tilt, and the level change.

                            The loudspeaker as sculpture -- very innovative design Wolf. Those can't fail to draw a lot of attention, even when they're not playing. They look great...

                              Ron- if you and Mark make it out here next Spring, you can hear them too! :D
                              Jay- Yeah, It came out okay!

                              Thanks for the comments, fellas. These were more of a challenge to build than many others I've done. I suppose 'speakers as art' really does apply here.
                              It's a shame I didn't take pictures when they covered in masking tape.....

                                Holy crap, bro!!! I was wondering how you were going to finish these and they look fantastic! You nailed it......That's a great mix of paints and it blends well with the baffle. Great job, as always. ....and it was a real pleasure getting to audition these before the Chicago DIY. :D



                                Quite a transformation :eek:
