"Trichotomy"- an oddly non-disparate design...

Those look great, Wolf!
And thanks for letting us see the tilt and level change of the final tweak.

Nice job Ben. I like the shape of these. Hopefully I will get to hear them one day.
As to the problem you had with your tape pulling the clear. One thing I do is buy my tape from an auto paint store. It's more money but better quality. I only use it to tape along the adjacent color. I then use cheap tape and paper to mask off the rest. The cheap tape only touches the good tape. When your done masking all you have touching your paint is one line of good paint. The better paint will also give you a cleaner line. I prefer 3M. Another tip is don't get your tape wet while it's on your project, like wet sanding, it makes it really tough to remove. Also keep your tape in a dry moisture free place. I also like to use mild wax and grease remover after I remove the tape, to say for instance, clear coat. Sometime the residue from the tape is left on the finish. I also wipe my project down with it before painting to remove any silicone's or oils from my hands before painting.

Hope this helps
Dave

I don't know why, but voicing a speaker using the Neo3 is a really difficult task, and yeah, I also got lots of sibilance when I worked on my 2 Neo3 design... it's interesting to see how you managed to control it!

I also think the damping pad on the chamber back helped too. Sounds a little less 'dark'.
Hope it's useful, the 20 ohm was mainly for level, but the zobel tamed it nicely.

Re: "Trichotomy"- an oddly non-disparate design...

What's funny is that where it pulled was not on the edge adjacent to the brass. The line was great and clean. It's on the top in a couple places, along a couple front vertical edges, as well as along the spine in the rear in a couple places.

I didn't wet-sand these, and I did do some wipe-down before primer. I think it's the questionable bond between the Polycrylic and the Chalkboard paint, honestly.

I thought about waxing with some Meguiars I have, after I touch up the clear in the spring. That'll be a few months.

Thanks for the advice, and the comments!
Wolf

PS- your wild advances in shape and style led me more in addition to making the speaker get what it needed to evolve into this form. They're not what I initially envisioned, but definitely appealing.

Re: "Trichotomy"- an oddly non-disparate design...

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.

Thanks, Bryan! I still think you did a wonderful classic look on the Speedsters too, especially for plywood.

The Trike's sounded better in the hotel room, that's for sure. The large room swallowed up their bass potential, and they were too far from the wall as well. Kind of amazes me they're in less volume than the Speedsters too....

Thanks, PI! Hope it clarifies some things for you. SSSibilance is normally manifested lower between 6-8kHz, and I think the spike at 12kHz was the main factor here, maybe even a harmonic of the normal issue.

Re: "Trichotomy"- an oddly non-disparate design...

Every time I think you've gone as far out there as you can go, you take it to another level!:eek:

It always seems to work out in the end, though, and I agree with Bryan that you really nailed the color combo here. I can see where the clear came off, but I'll just bet that it's exaggerated somewhat by the flash. In a longer shot with natural light, I'm betting it's darn near invisible.


I can't WAIT to hear them!:D


Nicely done, my friend!

Hopefully I step up everytime I build something. It's an escalator you know....
Thanks! I try to push the limits.

Re: "Trichotomy"- an oddly non-disparate design...

Now that you have tweaked and finished, other than lower bass in the Vijon, which design do you pick as the winner from 55hz on up?

Looks great. I really like the finish.

These have about the same bottom end extension, as the Vijon is sealed.
I won't pick a winner, as they both have very nice qualities. It's tradeoffs and balancing them; that's it in a design.

Re: "Trichotomy"- an oddly non-disparate design...

Unlike Ben, who I suspect is still in the 'proud-papa' stage, I'm willing to pick a favorite, based on what I heard of the Trichotomies at Chicago DIY and the Vijon two DIY Iowas prior. I heard things with the Vijon that I just didn't hear with the Trichotomy; the integration between the planar and the large-VC Dynavox midbass was significantly better in the Vijon. I heard some kind of distortion artifacts (or maybe the FR variation) in the midrange with the Trichotomy that I couldn't quite block out, which I attribute to the difficulty in integrating a midbass with limited top-end extension with a planar that inherently doesn't like a low crossover frequency and responds by injecting distortion. The Dynavox mid seemed better-behaved in its transition to the Hi-vi planar in the Vijon.

I will need to hear the tweaked Trichotomy design in a week in Kentucky (with my own front-end components) to hear whether the kinks in the crossover were ironed out with the latest revision, but it will require a noticeable improvement from the Trichotomies (except in the bass) to challenge the coherence, clarity, and integration of the Vijon.

That's my opinion. (Ben, please don't kick my ar-se when I see you in a week.

Heh- you're entitled to your opinion, but I think the mass-load on the chamber really made a lot of difference. That's the only thing you will be entertaining as 'different' in a week's time. As drivers go, the Dynavox is better behaved than the D5G, but designs are tradeoffs, and all will be different. The BG is just fine and happy where I have it, so it would be FR variation for certain if that's the case.

We'll see how you feel in a week, Bigshot! :p;):rolleyes:

PS- and FWIW- the Vijon are a touch 'hot'. I did that for clarity and noticed little fatigue on those.

Yeah, well, whatever. The Vijon still stick out in my mind as being an excellent design that produced some really excellent sound; the Trichotomies still don't stick in my memory in quite the same way. They have an interesting look (and I'm glad you didn't paint them blue), but I don't think they come as close as the Vijon to 'state of the art' in terms of sound. I still think the D5G midbasses would be better with a large-voice-coil tweeter like the Morel (or even a modified Dayton) 1-1/8" domes which can reach down into the triple digit frequencies (if only just barely) for a smoother transition, and that would resolve the FR and distortion issues at the same time.
