Yeah...I'm really stoked about how the Othorn turned out. As Mike says once you start getting it shoveling out the bass it wants to jump around. Bracing won't help as the forces involved are moving...

No box for the 24" and I have too many other things to do to go about paying for and building a huge box for it just to test it and then scrap it. I wouldn't hold your breath it will likely be months...

Yes the adapter mounts directly to the 21" driver cut out. Tested it with the 5100 and it worked like a champ. Almost exactly as modeled.

I will have to look at the new 18 sound drivers. It has...

At this time the only drivers that model well and I know work well are the UXL and the 5400. The 21sw152 is not a match.

Did you model the new 18 sound driver in this cab? I haven't.

No revisions worth getting crazy about. Just incremental stuff like the bracing.

Correct. You need complex inductance modeling to even get in the ballpark with those types of drivers and HR can't do it. You can fool with the single generic LE parameter all day and you cannot make...

Good points have been made by diyspeaker guy. This is most likely a combo of the horn built being slightly different than the simulation for the reasons mentioned. I'm not familiar with this...

John I guarantee the impedance min was well over 8ohms by that point! Lots of heat.

Correct.

Also the 9515 MTX is a beast of a driver with a huge motor, aluminum shorting rings and a 4" voice coil. Look at the amount of power (voltages are listed) dumped into it to make the...
