Questions about modelling JBL 2226J
New to this forum...I now own 4 JBL 2226Js and 2 JBL 2225Js, I also own the JBL 2" CDs (I forget which model) that Im mounting on a IWATA-300 horn (LeCleach design from DIYAudio.com).
I have questions about the JBL 2226J.
I had some trouble with getting WinISD to accept the 2226J T/S parameters found on JBLs pdf but I think I have it working but does anyone else have the 2226J setup for WinISD so I can confirm they are right.
Also looking at the ported model it shows that the small ports have port velocity issues. The only model I could get the port velocity below 32ft/sec was using dual 8" ports.
Of course I wanted to just follow the 4648-8 enclosures which are 8 cu. ft, 40 hz tuning but the model tells me those ports will have huge noise issues....what gives??
Temporary thread kidnapping: apologies!
If this is the same penngray (can there be more than one :dont-know: ?) who asked

btw, are you able to measure the impulse of your K2?? There is a design discussion that a measurement of the K2 would help a great deal.
over on AVS (I'm filecat13), then grumpy is the guy who can do what you asked.
As it turns out, he's coming over on Friday to help me set up some 4-way actively quad-amped JBL L250s reborn as PT250s with inverted dome Ti drivers. :eek: He's got the gear to give you what you want if you're still needing the info.
Otherwise, carry on! :drive:
EDIT: By "help" I mean he does the thinking, I do the lifting and supply the components.
