Having a metal screen in front of a tweeter really messes things up when you measure with MLS signals. I would recommend doing a gated sweep to see how they compare.
Hey, I like the looks. If nobody wants them, send them my way. Probably may end up in a student project.

The impedance curve smooths out with them gone, so i assume it has some resonances.

I left the grille in, simply because I couldn't see a simple way of removing it. Does it just pull out, or do you have to dismantle the tweeter to get it out?
i just stick a pointed stick in (metal works best). lift an edge and then use a set of needlenose if it balks. It is just glued to the horn sides.

Well, after a couple of weeks of extreme busyness, I have time to look at this again. I need to get on, so I went out yesterday to get some timber, and found that SE England is undergoing a shortage of birch ply! In the end, despite trying several stockists, I had to get some marine grade hardwood ply instead, less laminations, but it seems fairly void free from looking at the edges.
So, my next issue with Soundeasy. Playing around with the enclosure designer last night, I found what seems to be a bug. Whatever I set the port diameter to in both the enclosure designer and the port analysis calculator, the rectangular box designer seems to use a much larger diameter for the ports than set in either of the two above windows. I'll post the driver file and some pics in a bit when I fire up the laptop so you can see what I mean. Not the end of the world, but annoying.
Now I just have to wait for this rain shower to pass so I can go outside and precut the 8x4's into a size I can get down to my basement workshop. 😉

Just installed SE14 today. I am in for a journey for sure!
Any recommendations on a good but not hideously expensive sound card?

Lots of discussions on this, but I'm quite happy with my M-Audio Transit.
Oh, and I found the dongle. 😉

I am using M Audio FireWire 410 and is working really well for me. It is completely mobile so I could use it with my Apple Power Book or with stationary G5 or PC. This box has two balanced or SE inputs that are Mike/Line level with switched Phantom power. So with Sound Easy you wouldn't need any other preamps and is very convenient - just plug the mike in and use other channel as reference. On the top of that it is very good and quiet 24/192 card. (192 on two outs and 96 on six other outputs) Here is the link:

One note for Apple Intel Power Books owners - Apple seems like has lowered voltage or available current on their FW400 buss on Power Books so the MAudio FW410 as well as higher end digital cameras or any other more powerful FW user are having problem if not additionally powered to AC. There is also another workaround - use adapter FW800-FW400, and that in some cases solves the problem if AC is not available.
AR2 I just started using the Firewire 410 and I'm having big problems. IR's that change, move around, occasionally disappear. Mostly it's the changing that is the problem. I can do ten measurements adn not only will the amplitude change but so will the response for EVERY measurement. Any tips?
I'm using a Toshiba laptop, I think a 2.2ghz celeron and 512mb or 1g of ram. I have to use a Firewire pcmcia card. I'm using the latest (January 2008 I think) drivers.

Hi, please do not take me as an expert since I am Mac guy, and using Windows only when I have to. Here are few things to check - if you are on XP than most likely you do not have enough RAM which will affect more or less everything. Than in that case increasing latency as pinkmouse wisely advised will certainly help. Try the same operation on desktop PC if available and see how it goes. Laptops do not perform as well as desktops and if suffocated with inefficient amount of RAM than you will see all kinds of side effects. There are no reason for your Toshiba not to work, Sound Easy is not to demanding app, just stuff some more RAM.
I had a similar problem but with a desktop machine with 1GB of RAM. It worked quite fine before I had to upgrade to Service Pack 2, but after upgrade it just slowed down dramatically. I added RAM to 2 GB and it came to life again. Not to scare you but I just yesterday got Service Pack 3. I am still to see how it works. Man I love Macs.
How do you have your FW410 connected? 4 pin or 6 pin firewire?

They cost $10,000 used? OMG - that is damn expensive! 😱
Pinkmouse, I think you said your Audax tweeters didn't work?
Would you like a pair of the J3 version? I could send you a couple if the shipping isn't too much.
I haven't tried that (Titanium) model but I got some of the textile dome version because I liked them very much and they were on closeout for $9 ea. The only criteria that I used to form my opinion are: FR, dispersion, and power handling (by power handling what I mean is that we really had to TRY to blow them with a 300 watt Crown power amp, even WITHOUT a cap on them to protect them).
Now, I haven't done any distortion testing myself, so I'm not sure if maybe Audax's recommended crossover freqs are a little conservative? : http://www.hautparleur.fr/_audax/tm020j3.pdf
According to that .PDF, the 30 degree off axis response is almost ruler flat, almost all the way to 20Khz. Much better dispersion than the typical 1" - 1 1/8" tweeters...
An externally hosted image should be here but it was not working when we last tested it.
pinkmouse said:
Oh, for some reason I thought I saw you posted a picture w/ 3/4" Ti dome Audax tweeters.
I remember reading about the HD3P tweeters when they were new, looked nice, but a little overpriced.
edit: Harmon sucks for taking Audax out of the diy market...

I don't see a latency setting in the M Audio control panel?
I'm using the 6 pin cable.
Do you think ram would be a problem just with firewire? Because it works fine with MAudio Transit.
Thanks for the help!
Ok, lets go one at the time. Since you are on 6 pin FW do you have M Audio Power supply connected while you are doing measurements or you use just power supplied from FW?
