Feedback needed
 
Hi,

I have just finished my software, and would like to get more feedback on it.

Speakerbuilder Pro 2.0

Is the layout good?
Does it do what you need?
Does it look good in exotic browsers like Internet Explorer too?
And so on.... :)

Hope youll help making this even better, by applying your feedback.

It seems to be working okay.
It seems to follow the same predictions as Winlsd on my latest subwoofer box using 3 X 8" PRO-CSW800 Radio Shack subwoofers in a 3 cu.ft. box tuned to 26hz.
The ports seem to be the correct length at about 2 X 4"dia X 33"L.
I am using Chrome ver14 right now and it is the Bomb compared to IE8.
I would like to see a group delay chart and maybe a spl output chart.
I like the idea of seeing all of the charts at the same time when I make a change of a parameter,Winlsd does not do this.

Great job and keep up the good work!
I will play with it some more and let you know when I come up with some more idea's for you to implement.

I have it bookmarked. Now I will only have to go upstairs to the UNIX box in order to model horns and TLs. ;)

Hi,

Thank you :)
Groupdelay is on its way, as is impedance.

Can you define SPL output?

U/Linux rocks. Most of my coding is done on Linux/Fedora/CentOS. :)

Please keep good ideas coming :)

The Spl out when driven by the signal.

Maybe ireleavent, But Winlsd does this and is good to show when comparing number of drivers to excursions.
Where as the transfer curve is the frequency response and spl would show the theoretical output curve as per power in.

Although this can easily be calculated in the head but seeing the graph with the numbers some times gives you a different perspective on what you should expect to hear and/or experience.

like this example.
Had I changed the scaling the curves would look a little different.
I just did this quick and then I had to find a .xps to .jpg converter,What a pain!

But maybe you will get what I am saying.
Either way I like your program alot.

Here is an example with the scales set something what I like.
Fr +6db to -12db

spl 0db to 130db

Here is the same example with the fr set to +12db to -12db.

Anyway it is just a thought.

Nice! Works good in Chrome and on dial-up.

Hi,

Gerald > I have that i mind. Maby when the last graphs is done, ill make an dropdown where different scales can be selected, or customized. The graph component i made (that draws the responscuves) allready support this. So it should be easy for me to do.
