Is there a way in HR to specify the scale or just the 2 options for scale? For doing ported do I use the Vtc and Atc for volume and cross sectional area then derive length? Any quick pointers for designing ported in HR?
Horizontal (frequency) scale? There's just the two options. A couple of weeks ago there was only one option.
Hover over the input boxes and look at the bottom of the input window, it will show a description of what the box is and what it's for. Or look in the help file.
In this case, Vtc is volume of the throat chamber and Atc is area of the throat chamber.
Ported boxes can use either the rear chamber (Vrc and Lrc) to define the chamber or they can use a throat chamber instead (Vtc, Atc).
If using a rear chamber the port is defined using Ap, Lpt (area and length of port), if using a throat chamber the port is described using the segments (S1, S2, L12, etc).
Using a throat chamber as the ported box chamber allows you to use different shapes of port, for example flared ports.
Double clicking most input boxes will initiate a wizard that will help you fill in that box.
If you don't understand any of this just ask. The more specific the question the more likely I'll be able to help.
What is the Qa, Ql, Qp and Qicl? The first 3 show up in WinISD for ported and that 4th one shows up in ABC.
All those Qs are loss factors for the box, the port, etc, you can look up what they are and what you should set them at. Most other simulators assume no internal losses, this is just one of many reasons WinISD sims won't match sims from other simulators.
Edit I got the basics for ported and realize I got the 2 parameters mixed up with the ones I mentioned. What are those for Vtc and Atc? Is that to specifically set driver size to figure out how much volume to take away from box volume?
Also is it possible to run multiple sims side by side like WinISD? Or even multiple instances of the program? It won't let me open multiple instances off the single file location but I haven't tried making multiple file locations.
I already talked about Vtc and Atc. I answered a lot of questions with pictures about how to sims sealed, ported and tl boxes but I can't find the thread now. Maybe later.
Hornresp can overlay a current sim and a single captured sim, like I showed in the sim pics earlier.
But yes, you can run multiple instances of the program, I've run as many as 4 at a time side by side but there's no limit to how many you can run. You can likely put them all in the same folder too, just give each separate copy of the program it's own folder and unique name and you should be good to go.
Most of the time you won't need multiple instances - the Loudspeaker Wizard allows instantaneous changes so you can run through multiple design changes and watch how it affects the situation in real time.
