I wouldn't know, only continental US gets free shipping. For international buyers they actually charge more for shipping than the shipping costs. And even though its international my previous orders were just sloppily dumped into a single thick box that didnt survive the journey, the drivers were in cardboard sleeves and not secured in the shipping box any way. Smaller items free to bounce around inside. I forget what percentage of drivers arrived damaged but it was way too high and way too expensive to do anything about it.
NOT doing that with $1000 (Cdn) drivers, especially when the first batch of these 21s is full of factory defects too. But Canadian retailers are notoriously slow up updating new inventory and marking it up unreasonably high.
Talking about pe in case it's not clear.
Indeed!
Looks OK higher up in an offset driver ~236 L 2:1 CR pipe, otherwise end loaded does too.

Don't forget to include the semi-inductance parameters in your sims. They can make a significant difference in the response curve for high Le drivers like this one.
