Time for some Ansonica - a new design for Jagman's theater

[cjd]

Well... weather this weekend looks garage-shop worthy! Here's hoping I get everything cut right the first time and get to slopping some glue around!

[jagman]

Now the real fun begins!

[cjd]

We have sawdust!

[cjd]

And we have parts, baffles routed, all set to start assembly.

[---k---]

They are a lot smaller in person than I was expecting. The laminated baffle looked real good. Looking forward to hearing them some day.

[evilskillit]

You're building a new design, with a new driver and making little 1 line posts that say things like "did stuff". Allow me to be the first to say.



Seriously tho, I'm excited to see how this thing turns out. If you get a chance take some more pics and throw em up on the way. Also if you can, bring em by when you're done. :W

[cjd]

I'll get pics but i was just plain worn out.

[evilskillit]

I know the feeling. I never feel like taking pictures when I've got a good head of steam and am getting a lot done. Often afterwards or the next day I'll think that I may want some memories, or someone might benefit from what I did. So I'll snap a few finished product pictures or stage some bogus in progress pics from finished stuff if possible and take em. Well when you get around to it, give us some eye candy. Some of us live vicariously through you ya know.

He also had some jerkoff bothering him yesterday. He dropped off 5 speakers and was demanding crossovers be designed.

The cats said "thanks!" by the way. they love their new scratching post/climbing tree thing.

AHAHAHAHAHAHA

=D =D =D =D

edit: I am assuming this is a joke. =)

[cjd]

Now less worthless...

Missing: tweeter back. I mis-measured that one piece, but as the tweeter isn't even as deep as the baffle it will be quite easy to remedy either way. Also missing is the back, but you can see where it should slide into place.

This is dry assembled.

Slot port, as you can probably tell. I'll probably take a quick round-over to the back corner of the port as well as probably smoothing the woofer relief a little. Chamfer on the box edges will be done after assembly (and done on the table saw or router table, NOT hand-held).

[---k---]

You're going to run the roundover over the braces holes also, right.

[evilskillit]

Looks sharp man. Can't wait to see some more eyecandy and measured response.

[numberoneoppa]

That looks astonishing.

[cjd]

I've not had to make so many jigs for a project in a while. Safety first though, and a proper jig can be a huge part of that.

[savage25xtreme]

off topic, and I am sure you have post this before, but what camera and lens are you using for those low light shots?

[cjd]

Canon 30D, Tamron 17-50mm/2.8 - these shot at 1/50th f5.6ish iso800. The new 7d kicks the pants off the 30D for low light, too. Must.Resist.New.Toys.

[savage25xtreme]

I am trying to resist getting into the photography hobby, you are making it difficult. Keep up the good work on the speakers, but post some fuzzy crappy pics like I do

[cjd]

Does it help knowing that my degree is in Fine Art, with a minor in Photography (only a minor because I'd already been studying it so long and becoming a Drawing major gave me more room in my schedule to branch out even more...) ?

kinda... I will say that the main reason I want to get into photography is to capture retrievers in action, my other passion in life besides home theater (which I cant afford either). The deterrent is that to get a nice camera and lens to do that is on the order of 2k+.

To capture a retriever and all its drive and desire in a still is something I have dreams about! wayyyy off topic and I apologize. Maybe I will take it to PMs as I would like to get your thoughts!

Is that LBL, by any chance? It looks like there is a lot of voiding in there for the expense, if it is. This is starting to look like a great design, though. Good work!

[savage25xtreme]

I was wondering that as well, but Jon's LBL has much wider lamination. Chris's looks like plywood laminated. Please enlighten us Chris

[numberoneoppa]

Doesn't look like bamboo to me.

Yes, you want a 7d and a nice fast lens, maybe IS. You'll almost always shoot bursts. Check out photography-on-the.net

The floor is LBL (horizontal laminates, 6" wide). The box is birch plywood, best I was able to source locally. There are a few voids but very few. I guess I picked the worse of the two baffles with regard to voids. They will get filled, mix of sawdust and glue.

Much of what may look like void is just knots in the core ply layers, from what I can tell. It's not 13 ply 18mm either, little wider. I couldn't find 13 ply that wasn't a void-fest.

was actually looking at a D90 with a 70-200mm 2.8

Well, if you want to swing that way I suppose...

only 4.5fps burst on it, and only ISO3200... Certainly workable, as just a couple years ago that would have been an awesome spec.

7d is 8fps burst, ISO12800 but a (worthwhile, IMO) solid jump in price - it's still my recommendation. For lower price I'd look at the T1i (500D) Canon: has ISO12800 but only 3.4fps burst. Both shoot 1080p also, though the 7d is required to maintain up to 30fps. With the extra ISO (it's amazingly clean, by the way - less noise at 12800 than my 30D at ISO1600) you can keep shutter speed up in crazy low light conditions.

I've never been a fan of Nikon, and that goes waaaaay back to when I was using my Canon F1's and got to play with some Nikon F2's... Realistically, they do a fine camera.

C

[savage25xtreme]

I have no doubt the 7d is excellent but its twice the money of the D90... Have to draw the line somewhere

I may have to look at the canon line-up. a local friend shoots nikon so that is all I have been looking at.

Got it. The baffle is a bunch of thin strips glued top-and-bottom and turned on edge to get the "edge grain" (ply). I had thought it might be the vertically-oriented LBL, but I get how you have it laid up now. I can be a bit slow.

Good camera, great lens. That lens is 2000 dollars, though, last I checked (assuming you're talking Nikkor). I shoot a D80 (have since it came out) and I'm pretty darn satisfied with it. I've yet to reach the camera's potential in most situations - the glass I have truly being the biggest bottleneck for PQ.

7D is sexy. Rather have a D700, though. Nikon <3 <3 <3

Oh, and if you do stretch your budget, go full frame.

[cjd]

On-topic. Going to have to haul out the table saw to do some trimming on the braces, my calculations did not properly account for the angle I think, so they're all ~1/8" too long. Which is better than too short, so I'll take it.

Oh, and if you do stretch your budget, go full frame.

Disagree in this context, since you'll likely be pushing for more zoom and APS-C sort-of gives you this for free.

D700 is really nice, even pricier than the 7d though.

I believe the Sigma 70-200/f2.8 is available for both folks that have seen the light, and folks that haven't... er, I mean, Canon and Nikon. My copy is excellent, though I'm one of a few people that could consistently tell which lens was which vs. the Canon L variant.

[savage25xtreme]

Thomas is going to scold us for sure for all the camera talk.

CDJ, what was your reasoning for doing the ply on its side like that? strength or aesthetics? seems like a lot of work, but I think it looks sharp.

[cjd]

Ummmm... I knew these would need a thicker baffle and I have been getting bored with normal construction - so I got curious, thought the aesthetics would be good, figured I'd try it on a smaller project. I think I like it. Will be especially interesting once I get the die job done, but that will be a little while - measurements and crossover first.

I like things that don't try to hide how they're made - classic joinery comes to mind. While I'm not planning to dovetail my next speaker, I think that could be interesting. Ply doesn't really lend itself to that.

Also, some other projects I have in in the works will be easier to do laminated, but I needed to try the process first on something simpler.

I think it's also providing more native damping on the baffle, but that's not a scientific observation.

Sweeeeeet.... How does your back feel?

[cjd]

Sweeeeeet.... How does your back feel?

My back? My back is fine. My hands and the associated tendons in my forearms aren't so thrilled - the orbital sander and the large chamfer router bit both induce excessive vibration and such...

The final glue-up of the first enclosure is currently clamped happily together - they're starting to be a little heavy for casual lugging, but not too bad. They're small still.

[evilskillit]

If you're used to working with MDF they're probably lighter than you think. Every time I heft my 43" tall birch boxes all I think to myself is "man I'm glad these aren't MDF, they're so light"

[cjd]

32 pounds flat before chamfer, box only.

Very Nice

[numberoneoppa]

fapfapfap

Very nice, how are you going to finish it?

[savage25xtreme]

very slick! set the drivers in there so we can really :drool:

[cjd]

What, me finish?! Nooooo, never.

If I can properly clean up the glue lines this will be given a die job to an adequate state of purple-ness, then clear-coated to a mild sheen, or till I get tired of finishing...

I just got back from the doctor, I have Strep throat... yay. Progress thanks to illness. I guess it's not all bad (I've worked from home yesterday and today, thankfully it seems, as I may not get anyone else at work sick...)

[cjd]

Yes, it goes low.

Yes, it's easy to overdrive without a rumble filter if you feed it stuff <20Hz.

wheeeee. :B

[evilskillit]

Looks very nice, definitely a lot of potential there with a bit of round over or chamfer on front or something and a neat finish. It'll probably be a very popular design. Especially over at hometheatershack where all the little exodus audio fans are going nuts waiting for a good Anarchy design.
