Just use VirtualBox and boot a copy of Windows proper in a VM.

Hi!

Now hornresp works, i didnt recognize that my old win-pc is repaired and works again. LOL

In hornresp, i tried to simulate single usb loaded with rcf lf18g401.

Single usb
s1= 825.60
s2=877,2
con=13
s3=1210
con=20.5
s4=2770
con=33.5

vrc=46.5
lrc=22.7
fr=0
tal=0
vtc=31205
atc=2100

But when i want to change the driver arrangement to 2 parallel (full usb),
i only get : Vrc / Lrc { 2x Sd.

I dont think that doubling VRC and LRC is the answer, because VRC and LRC belong to one
driver, right?

Please help
thx
Avatron

If simulating a full USB, you simulate it as one large horn, so all areas and volumes combined, and then pick 2 drivers.  Alternately, if you have a half USB simulated, then use the multiple speakers option to simulate two halves together.

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?"

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

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

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.

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.

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
