The tweeter is a "GR Neo 3" which is planar magnetic design.
If by "LA" you mean "listening area", not tapered, damn near a square.
But with the open baffle speakers it is manageable and not as hard to wrestle with as a sealed or ported speaker would be.
I got a lot of help on dialing the room in from Greg and Dave at PI Audio Group (I believe they are located in your neck of the woods JRS). Their advice was a huge help.
Once again, as far as bass for music goes, if you have the space, then the open baffle options are worth considering.
I plan on moving a few things around next weekend and will likely tweek the PEQ and go through a whole new round of measurements as I squeeze every last bit of performance I can out them.
If there is specific measurement on the subs (or the speakers for that matter) accessible within REW that interests the forum, I will happily run it and post it here. Please remember, my name is not Amir and my skill level is pretty close to that of a monkey with a microphone,
so mileage may vary.
Now if Amir was interested in traveling over the mountains to give these a listen and run his own measurements, he is more than welcomed.
