Has anyone modeled Just he top of the Altec A7(825) cab. The ones that people cut down and just use the horn section? I just got a pair and for the life of me, I can't figure out HR. I can cut, weld, design....but I am NOT good with programs.

djn,

I have done the 828 together with 416-8B. Not a pretty sight! What driver do you have?

I simmed the compression loaded ones I use to do in MJK's original FLH WS to proof its overall accuracy. It has maybe a bit too much built-in acoustic smoothing though for some of the folks here though. I'm busy with house repairs ATM, but as time permits I'll load them into HR to see if they look as ugly as Lars indicates. For sure, me and the folks I did them for thought they sounded pretty good at the time [~1968-1975].

"not a pretty sight" How so? I will be using the Lambda TD15x drivres. interestingly....the T/S of the TD15x is VERY VERY similar to the 416.

Thanks GM, much appreciated. I also have 4 really good subs to fill in the bottom end.

I will be using the red Edgarhorn and Heil in this pic on these cabs. I am moving to a smaller place and the big scoops are too big for my new room.

So copy and paste isn´t to bad.

Eventually not so much to discuss the result is the same.

Any one found a working, easy to use, Excel to CAD-program converter?
I recall there is a script for SolidWorks called Points Import or something like that.

Hey GM,
What, compression? Do we mean the same cabinet? Didn´t everything sound great for a couple of years after Woodstock? Yes, it is a joke so don´t mind! I for some reason liked the dreadful production Klipshorns.

djn,
About not a pretty sight they aren´t! Needs smaller box other porting and maybe another flare in the horn.

OK, here is what comes out of HR. All dimensions aren´t exact but good enough. On-axis is acceptable.

There is an interesting article somewhere about Exemplar.

Hi Jean-Michel,

That's a great idea - after several hours simulating on Hornresp, most users are probably ready for a cup of coffee :-).

I will add it to the wish list... :-).

Kind regards,

David

About VOTT, tune it to ca 40Hz. With 1,8cm baffle thickness it will be something like 200cm2.

Lambda TD15x
djn,

where are the T/S parameters? They are not AE´s site. This is all there is:

FS: 23.2Hz
Qts: 0.28
Vas: 467L

Estimated the other values in course sim and I guess it is better to check the drivers from Great Plains. The main reason is TD15x´s high cone mass.
