And if you take the time to realise why it thinks some of your TS are wrong, you will realise what the most important TS figures are and why the rest of them are secondary and derived from the primary set. Which in turn helps you get a feel for a driver by looking at its data.

Well, realistically you are going to have to do what the rest of have done. 

Go through the help file included in the program and then work through (from the begining of the thread) some of the examples given by various DIYers. I would even suggest taking notes that you can refer to. This is a powerful program that will save you from many false starts. It is worth the time & effort.

For TL designs, there is other software that may be more appropriate. Again, use the search fucntion and work through some of the threads. There is no magic 100-word summary.

I gave up with WinISD and went Bass Box Pro. It doesn't have hiissy fits about T/S it THINKS are wrong and produces the results expected
It's everything, not everythink!

The 200ltr Fane constructor box for 18xb etc. Four ports. I put the 18xb in a 200ltr box in winisd got the response to a pretty flat line but the 4x ports were at least 3 times the length of the plan for the same diameter. When I tried it with the suggested length for the ports the graph did not look right at all,
huge short bump and a very high cut off. I don't have access to the pc right now so I can't give actual
figures. I tried with the 12" cab from the constructor series (2 ports) and got ports approx' 3x as long as the plan again to achieve the suggested cut off. When I modeled a 20ltr box with one port all went well,
the box behaved as expected when built. I modeled a box 20ltr for the same speaker with 2x ports, built it but found myself cutting down and widening the ports quite a bit, a lot I'd say, to get a similar
response to the 20ltr with the single port. The double 15" al a Tony wilkes I modeled for my driver,
shortened the port a little as It is primarily my kick bin, always plays out doors and doesn't need the low extension. That works just as predicted, single port again. "Baffled" I amConfused

High, I have used winisd in the past to build a boom box, a small 20ltr monitor set and a double 15 slightly modded from Tony Wilkes design on here. With the boom box and the monitors I had to do extensive re-shaping of the ports (multiple) to get the response I was aiming for. The double 15 behaved as expected (single port). I recently put the 200ltr fane box into winisd and got port lengths about three times the length of the plans (for a reasonably flat response from an xb). So I put in a couple of other recommended plans with multiple ports and had similar results. I read on another forum that the program has trouble with multiple ports. Can someone here confirm that? Or am I going for too flat a response? I don't think so because the bump in low frequencies seems huge with the winisd port lengths
recommended. I hope I havn't missed this some where, couldn't find it in this thread.

My last post wasn't clear enough written! 

The Xmax problems start at 100 Watt (as far as i remember), this is the thing i wonder about.

Also in my last post i tried to sim USB + RCF LF18G401.
But i will use the Celestion FTR18-4080FD!

In the second sim (with celestion) i also get xmax problems at ~100 Watt!
So i did something wrong, but i dont know what.

you wonder why you dont get over 146db for six cabs so ~139db out of a single BPH without getting probems with xmax ?

Can someone verify my simulation, please?

I think that this is the right thread for this simulation, because its my first try,
and i believe there is an error somewhere because the cone excursion.

If a moderator read this, please correct me if i'm wrong and i will post in the 
"database simulation" thread in "other plans"!

Input data:


Respone half usb


gettin a warning, when i try to sim more than 3 speakers


response 6 half usb (3 full usb)


MaxSPL (3 full usb)


Diaphragm displacement


thx in advance

thx i found it!

It works for simulating 1 - 3 speakers.
But when i try to simulate 4 or more speakers (in this case 4 or more single usb)
i get:

"Caution Horn Segment 3 normalised 4 pi mouth circumference in exponential flare cutoff
frequency wavelengths = 1,04"

"For multiple-segement horns, the more that value of Cir excedds 1 for any horn segment, the less
accurate the calculated throat acoustical impedance and other results become.
Are you sure you want to continue?"
