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

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

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.
