tweaking caps / resistors in a zobel network ?
luvdunhill replied to Spiug31's topic in Do It Yourself
hm good question. I expect most people would say it isn't worth it. I would say that, until you came back and told me that you are driving speakers with these that have a significant amount invested in the crossover. Let's say approximately the same cost as the drivers themselves. That pretty much rules out most commercial speakers.... and after this, you tried to convince me that it makes sense to spend money in this zobel, because after all, it serves the same function as the zobels you integrated into each driver in the crossover (again, something that isn't always done to start with, zobels before the driver that is).... ... then I'd just ask why the heck are you using a beta22 to drive speakers of that implied caliber... -
Additional memory (Macintosh)
luvdunhill replied to archosman's topic in GoRedwings19's Computer Help Hotline
hm. I might be looking to upgrade my mini memory, and heard rumors that you can stick 6G in it? Anyone know the exact model people have successfully used? -
yeah, but then you have to pay sales tax. Not much of a discount. Just buy it online via Macmall (assuming you don't live in one of the two states that they must charge sales tax) and don't mess with the Edu discount.
-
so, after you get the credit from Radio Shack, what are the prices for the phones, assuming no incentives from AT&T? I cannot seem to find this info...
-
huh? still Intel Core 2 Duo... well, at least I'm not pissed that I bought mine when I did.
-
I have Gerbers somewhere. But are you really asking for a schematic, or looking for a set of TH boards?

So, Pete about those Jordan's.........you were saying, not like any other full ranger? -
which plug-in are you looking at? Here's a list: MiniDSP - Audio plug-ins More info on the associated datasheet, for example, here's the datasheet for the "2-way advanced" http://www.minidsp.com/images/documents/Product%20Brief-%202way%20Xover%20ADV%20plug-in.pdf If you want, you can always ask them. Just don't be an like this guy: http://www.diyaudio.com/forums/minidsp/158963-minidsp-kits-our-answers-your-technical-questions-17.html#post2186514

Dusty: I'm glad that they don't try to be a TI/Analog Devices/Xilinx and provide the support those companies do. Why do you think these companies charge so much for an eval board? Answer: support. If you want to use an IDE (which are pretty much locked into a given manufacturer anyways), then go ahead pick on the above and get ready for sticker shock (25x - 50x part cost is average). bhjazz: Pretty close to impossible. That comes from someone whose day job is reverse engineering.

Craig: Why not look locally for your wire? I've used this source in the past with good luck: WIRES.CO.UK Online Catalogue Nate: I haven't had that experience, but thanks for the heads up.
-
I think that will work for me Kevin, since I have the longer heat sinks. This are the standard diameters that Plitron will offer, hence the question.
-
This isn't the best place for this, but some of you might be interested in this: MiniDSP I'm planning on trying one out for a few things
-
so, 80 VA roughly each. How would 95-97mm diameter fit (all three this diameter)?
-
Cool Ari. Must have that Brew Dog photo in avatar size!!! Mine didn't come out nearly as well ...

Aurum Cantus G2si. Ignoring Colin, because Zaph has distortion measurements for the G3si, and the G2si cannot be that bad, right? Aurum cantus http://www.aurumcantus.com/aurumcantus-tweeter/aluminum%20ribbon%20tweeter%20G2sipic022.htm
-
that's a very cool option... hm.
-
In that case, let's view this initial run as "prototyping". If anyone wants in, let me know, but I plan to act on this pretty quick. I'm not exactly clear on how to deal with the extra length, but I need to look things over. My first impression is that shoving the board to the rear of the case is the way to go. It's not that much longer really.
-
ah, okay I was confused because some people (like deepak) had boards and didn't have cases. I guess that implies that Kevin has left over cases. If there is a 1:1 correspondence, then perhaps my services aren't needed. I want to make sure all of Kevin's cases get sold.
-
Just out of curiosity, how many boards were originally made, and how many cases? Ok, I have a ball park on the heat sinks. Absolute worse case, including shipping to you is about $300 for a set of four in 100mm lengths anodized. If you want black anodized, we can do that for the differential above. That's $75 each. There is a lot of padding in there, trust me, in case I get hit for import taxes and fluctuating exchange rates. That's not cheap, but given the fact that this profile isn't easy to find (even for Kevin) I think it's fair. I will obviously refund any overage, but I want to cover my ass. Also, please buy Kevin's stuff before considering this. I don't want to step on his toes. Must stay in good graces to qualify for those mounting brackets

Cool. Any reason to think that these accounts would allow a package to originate internationally? Looks like I may try FedEx.
-
I've run into the need for some sort of shipping account a few times in the past, and recently ran into this again. Is this something that's hard to setup, or perhaps not worthwhile for occasional use? If I were to find someone that had an account I could use, is there any sort of authorization, or do you just give the shipping party the number and an address and the package shows up and the account is charged? Seems like that could be abused pretty readily. Anyways, if anyone might be able to help with an account number, PM me Otherwise, I'm trying to talk the vendor out of this requirement or seeing what it takes to set one up on my own. Thanks!

I think I just found some inspiration for a project:

The price I am able to get for the above profile is 28.77 eur for raw aluminum and 37.09 eur for black anodized in precut 100mm lengths. Shipping is still to be defined. My German is a little rusty and had to ask for clarification. Depending on this answer, I might take on a few extra pairs. Here's an example of this profile, if you need something more visual (obviously a little taller than 100mm length though):
